COROLLA MATRIX (EM00F0U)

Engine Control for 2ZZ–GE
System Outline
The engine control system utilizes a microcomputer and maintains overall control of the engine, etc. An outline of engine
control is given here.
1. Input Signals
(1) Engine coolant temp. signal system
The engine coolant temp. sensor detects the engine coolant temp. and has a built–in thermistor with a resistance which
varies according to the engine coolant temp. Thus the engine coolant temp. is input as a control signal to TERMINAL
THW of the engine control module.
(2) Intake air temp. signal system
The intake air temp. sensor is installed in the mass air flow meter and detects the intake air temp., which is input as a
control signal to TERMINAL THA of the engine control module.
(3) Power steering oil pressure signal system
Power steering oil pressure is detected by the power steering oil pressure SW and is input as a control signal to
TERMINAL PSW of the engine control module.
(4) RPM signal system
Camshaft position and crankshaft position are detected by the camshaft position sensor and crankshaft position sensor.
Camshaft position is input as a control signal to TERMINAL G2 of the engine control module, and engine RPM is input
into TERMINAL NE+.
(5) Throttle signal system
The throttle position sensor detects the throttle valve opening angle, which is input as a control signal to TERMINAL VTA
of the engine control module.
(6) Vehicle speed signal system
The vehicle speed is detected by the ABS speed sensor and the signal is input to TERMINAL SPD of the engine control
module via the comb. meter and the skid control ECU with actuator. (w/ ABS)
The vehicle speed is detected by the vehicle speed sensor installed in the transaxle and the signal is input to
TERMINAL SPD of the engine control module via the comb. meter. (w/o ABS)
(7) A/C SW signal system
The operating voltage of the A/C SW is detected and is input as a control signal to TERMINAL A/CS of the engine
control module.
(8) Battery signal system
Voltage is constantly applied to TERMINAL BATT of the engine control module. When the ignition SW is turned to on,
voltage for engine control module operation is applied via the EFI relay to TERMINAL +B of the engine control module.
(9) Intake air volume signal system
Intake air volume is detected by the mass air flow meter, and is input as a control signal to TERMINAL VG of the engine
control module.
(10) STA signal system
To confirm that the engine is cranking, the voltage applied to the starter motor during cranking is detected and is input as
a control signal to TERMINAL STA of the engine control module.
(11) Oxygen sensor signal system
The oxygen density in the exhaust gases is detected and is input as a control signal into TERMINALS OX1A and OX1B
of the engine control module. To maintain stable detection performance by the oxygen sensor, a heater is used for
warming the sensor. The heater is also controlled by the engine control module (HT1A and HT1B).
(12) Engine knock signal system
Engine knocking is detected by the knock sensor (Bank 1) and input as a control signal to TERMINAL KNK1 of the
engine control module.
(13) Electrical load signal system
When systems which cause a high electrical load such as the rear window defogger, taillight are turned on, a signal is
input to TERMINALS ELS and ELS2 as a control signal.

66

COROLLA MATRIX (EM00F0U)

2. Control System
∗ SFI system
The SFI system monitors the engine conditions through the signals, which are input from each sensor to the engine
control module. Based on this data and the program memorized in the engine control module, the most appropriate fuel
injection timing is decided and current is output to TERMINALS #10, #20, #30 and #40 of the engine control module,
operating the injectors (to inject fuel). This is the system which finely controls the fuel injection in response to the driving
conditions, through the engine control module.
∗ ESA system
The ESA system monitors the engine conditions using the signals, which are input to the engine control module from each
sensor. Based on this data and the program memorized in the engine control module, the most appropriate ignition timing
is decided and current is output to TERMINALS IGT1, IGT2, IGT3 and IGT4 of the engine control module. This output
controls the ignition coil and igniter No. 1 , No. 2 , No. 3 and No. 4 to produce the most appropriate ignition timing for the
driving conditions.
∗ IAC system
The IAC system increases the RPM and provides idle stability for fast idle–up when the engine is cold, and when the idle
speed has dropped due to electrical load and so on. The engine control module evaluates the signals from each sensor,
and outputs current to TERMINAL RSD to control the idle air control valve.
∗ Knock control system
Knock control system controls the gate based on the engine rotation speed and detects knocking by the peak value of the
knock sensor (Bank 1) output during the gate open period, and then controls it to the most suitable ignition timing in
proportion to the driving condition.
∗ Evapoparge control system
This system leads the vapor stuck to the canister to the serge tank in order not to agitate the air fuel by adjusting the fuel
injection volume.
The signal at this time will be output from TERMINAL PRG of the engine control module to VSV (Purge).
3. Diagnosis System
With the diagnosis system, when there is a malfunctioning in the engine control module signal system,the malfunction
system is recorded in the memory. The malfunctioning system can be found by reading the display (Code) of the malfunction
indicator lamp.
4. Fail–Safe System
When a malfunction occurs in any system, if there is a possibility of engine trouble being caused by continued control based
on the signals from that system, the fail–safe system either controls the system by using the data (Standard values)
recorded in the engine control module memory or else stops the engine.

COROLLA MATRIX (EM00F0U)

Engine Control for 1ZZ–FE (4WD)
System Outline
The engine control system utilizes a microcomputer and maintains overall control of the engine, etc. An outline of engine
control is given here.
1. Input Signals
(1) Engine coolant temp. signal system
The engine coolant temp. sensor detects the engine coolant temp. and has a built–in thermistor with a resistance which
varies according to the engine coolant temp. Thus the engine coolant temp. is input as a control signal to TERMINAL
THW of the engine control module.
(2) Intake air temp. signal system
The intake air temp. sensor is installed in the mass air flow meter and detects the intake air temp., which is input as a
control signal to TERMINAL THA of the engine control module.
(3) Power steering oil pressure signal system
Power steering oil pressure is detected by the power steering oil pressure SW and is input as a control signal to
TERMINAL PSW of the engine control module.
(4) RPM signal system
Camshaft position and crankshaft position are detected by the camshaft position sensor and crankshaft position sensor.
Camshaft position is input as a control signal to TERMINAL G2 of the engine control module, and engine RPM is input
into TERMINAL NE+.
(5) Throttle signal system
The throttle position sensor detects the throttle valve opening angle, which is input as a control signal to TERMINAL VTA
of the engine control module.
(6) Vehicle speed signal system
The vehicle speed is detected by the ABS speed sensor and the signal is input to TERMINAL SPD of the engine control
module via the comb. meter and the skid control ECU with actuator. (w/ ABS)
The vehicle speed is detected by the vehicle speed sensor installed in the transaxle and the signal is input to
TERMINAL SPD of the engine control module via the comb. meter. (w/o ABS)
(7) NSW signal system (A/T)
The Park/Neutral position SW detects whether the shift position is in neutral or not, and inputs a control signal to
TERMINAL NSW of the engine control module.
(8) A/C SW signal system
The operating voltage of the A/C SW is detected and is input as a control signal to TERMINAL A/CS of the engine
control module.
(9) Battery signal system
Voltage is constantly applied to TERMINAL BATT of the engine control module. When the ignition SW is turned to on,
voltage for engine control module operation is applied via the EFI relay to TERMINAL +B of the engine control module.
(10) Intake air volume signal system
Intake air volume is detected by the mass air flow meter, and is input as a control signal to TERMINAL VG of the engine
control module.
(11) STA signal system
To confirm that the engine is cranking, the voltage applied to the starter motor during cranking is detected and is input as
a control signal to TERMINAL STA of the engine control module.
(12) Oxygen sensor signal system
The oxygen density in the exhaust gases is detected and is input as a control signal into TERMINALS OX1A and OX1B
of the engine control module. To maintain stable detection performance by the oxygen sensor, a heater is used for
warming the sensor. The heater is also controlled by the engine control module (HT1A and HT1B).
(13) Engine knock signal system
Engine knocking is detected by the knock sensor (Bank 1) and input as a control signal to TERMINAL KNK1 of the
engine control module.
(14) Electrical load signal system
When systems which cause a high electrical load such as the rear window defogger, taillight are turned on, a signal is
input to TERMINALS ELS and ELS2 as a control signal.

COROLLA MATRIX (EM00F0U)

2. Control System
∗ SFI system
The SFI system monitors the engine conditions through the signals, which are input from each sensor to the engine
control module. Based on this data and the program memorized in the engine control module, the most appropriate fuel
injection timing is decided and current is output to TERMINALS #10, #20, #30 and #40 of the engine control module,
operating the injectors (to inject fuel). This is the system which finely controls the fuel injection in response to the driving
conditions, through the engine control module.
∗ ESA system
The ESA system monitors the engine conditions using the signals, which are input to the engine control module from each
sensor. Based on this data and the program memorized in the engine control module, the most appropriate ignition timing
is decided and current is output to TERMINALS IGT1, IGT2, IGT3 and IGT4 of the engine control module. This output
controls the ignition coil and igniter No. 1 , No. 2 , No. 3 and No. 4 to produce the most appropriate ignition timing for the
driving conditions.
∗ IAC system
The IAC system increases the RPM and provides idle stability for fast idle–up when the engine is cold, and when the idle
speed has dropped due to electrical load and so on. The engine control module evaluates the signals from each sensor,
and outputs current to TERMINAL RSD to control the idle air control valve.
∗ Knock control system
Knock control system controls the gate based on the engine rotation speed and detects knocking by the peak value of the
knock sensor (Bank 1) output during the gate open period, and then controls it to the most suitable ignition timing in
proportion to the driving condition.
∗ Evapoparge control system
This system leads the vapor stuck to the canister to the serge tank in order not to agitate the air fuel by adjusting the fuel
injection volume.
The signal at this time will be output from TERMINAL PRG of the engine control module to VSV (Purge).
3. Diagnosis System
With the diagnosis system, when there is a malfunctioning in the engine control module signal system,the malfunction
system is recorded in the memory. The malfunctioning system can be found by reading the display (Code) of the malfunction
indicator lamp.
4. Fail–Safe System
When a malfunction occurs in any system, if there is a possibility of engine trouble being caused by continued control based
on the signals from that system, the fail–safe system either controls the system by using the data (Standard values)
recorded in the engine control module memory or else stops the engine.

COROLLA MATRIX (EM00F0U)

Engine Control for 1ZZ–FE (2WD)
System Outline
The engine control system utilizes a microcomputer and maintains overall control of the engine, etc. An outline of engine
control is given here.
1. Input Signals
(1) Engine coolant temp. signal system
The engine coolant temp. sensor detects the engine coolant temp. and has a built–in thermistor with a resistance which
varies according to the engine coolant temp. Thus the engine coolant temp. is input as a control signal to TERMINAL
THW of the engine control module.
(2) Intake air temp. signal system
The intake air temp. sensor is installed in the mass air flow meter and detects the intake air temp., which is input as a
control signal to TERMINAL THA of the engine control module.
(3) Power steering oil pressure signal system
Power steering oil pressure is detected by the power steering oil pressure SW and is input as a control signal to
TERMINAL PSW of the engine control module.
(4) RPM signal system
Camshaft position and crankshaft position are detected by the camshaft position sensor and crankshaft position sensor.
Camshaft position is input as a control signal to TERMINAL G2+ of the engine control module, and engine RPM is input
into TERMINAL NE+.
(5) Throttle signal system
The throttle position sensor detects the throttle valve opening angle, which is input as a control signal to TERMINALS
VTA1 and VTA2 of the engine control module.
(6) Vehicle speed signal system
The vehicle speed is detected by the ABS speed sensor and the signal is input to TERMINAL SPD of the engine control
module via the comb. meter and the skid control ECU with actuator. (w/ ABS)
The vehicle speed is detected by the vehicle speed sensor installed in the transaxle and the signal is input to
TERMINAL SPD of the engine control module via the comb. meter. (w/o ABS)
(7) NSW signal system (A/T)
The Park/Neutral position SW detects whether the shift position is in neutral or not, and inputs a control signal to
TERMINAL NSW of the engine control module.
(8) A/C SW signal system
The operating voltage of the A/C SW is detected and is input as a control signal to TERMINAL A/CS of the engine
control module.
(9) Battery signal system
Voltage is constantly applied to TERMINAL BATT of the engine control module. When the ignition SW is turned to on,
voltage for engine control module operation is applied via the EFI relay to TERMINAL +B of the engine control module.
(10) Intake air volume signal system
Intake air volume is detected by the mass air flow meter, and is input as a control signal to TERMINAL VG of the engine
control module.
(11) STA signal system
To confirm that the engine is cranking, the voltage applied to the starter motor during cranking is detected and is input as
a control signal to TERMINAL STA of the engine control module.
(12) Oxygen sensor signal system
The oxygen density in the exhaust gases is detected and is input as a control signal into TERMINAL OX1B of the
engine control module. To maintain stable detection performance by the oxygen sensor, a heater is used for warming
the sensor. The heater is also controlled by the engine control module (HT1B).
(13) Engine knock signal system
Engine knocking is detected by the knock sensor (Bank 1) and input as a control signal to TERMINAL KNK1 of the
engine control module.
(14) Electrical load signal system
When systems which cause a high electrical load such as the rear window defogger, taillight are turned on, a signal is
input to TERMINALS ELS1 and ELS2 as a control signal.
(15) Air fuel ratio signal circuit
The air fuel ratio is detected and input as a control signal into TERMINAL A1A+ of the engine control module.

COROLLA MATRIX (EM00F0U)

2. Control System
∗ SFI system
The SFI system monitors the engine conditions through the signals, which are input from each sensor to the engine
control module. Based on this data and the program memorized in the engine control module, the most appropriate fuel
injection timing is decided and current is output to TERMINALS #10, #20, #30 and #40 of the engine control module,
operating the injectors (to inject fuel). This is the system which finely controls the fuel injection in response to the driving
conditions, through the engine control module.
∗ ESA system
The ESA system monitors the engine conditions using the signals, which are input to the engine control module from each
sensor. Based on this data and the program memorized in the engine control module, the most appropriate ignition timing
is decided and current is output to TERMINALS IGT1, IGT2, IGT3 and IGT4 of the engine control module. This output
controls the ignition coil and igniter No. 1 , No. 2 , No. 3 and No. 4 to produce the most appropriate ignition timing for the
driving conditions.
∗ Knock control system
Knock control system controls the gate based on the engine rotation speed and detects knocking by the peak value of the
knock sensor (Bank 1) output during the gate open period, and then controls it to the most suitable ignition timing in
proportion to the driving condition.
∗ Evapoparge control system
This system leads the vapor stuck to the canister to the serge tank in order not to agitate the air fuel by adjusting the fuel
injection volume.
The signal at this time will be output from TERMINAL PRG of the engine control module to VSV (Purge).
3. Diagnosis System
With the diagnosis system, when there is a malfunctioning in the engine control module signal system,the malfunction
system is recorded in the memory. The malfunctioning system can be found by reading the display (Code) of the malfunction
indicator lamp.
4. Fail–Safe System
When a malfunction occurs in any system, if there is a possibility of engine trouble being caused by continued control based
on the signals from that system, the fail–safe system either controls the system by using the data (Standard values)
recorded in the engine control module memory or else stops the engine.

COROLLA MATRIX (EM00F0U)

Headlight
System Outline
The current is always flowing from the HEAD MAIN fuse to HEAD relay (Coil side) to TERMINAL 6 of the daytime running
light relay and from ECU–B fuse to TERMINAL 3 of the daytime running light relay. The current is always flowing from the
TAIL fuse to TAIL relay (Coil side) to TERMINAL 14 of the daytime running light relay.
When the ignition SW is turned on, the current flowing through the GAUGE fuse flows to TERMINAL 12 of the daytime
running light relay.
1. Daytime Running Light Operation
When the engine is started, voltage generated at TERMINAL L of the generator is applied to TERMINAL 8 of the daytime
running light relay. If the parking brake lever is pulled up (Parking brake SW on) at this time, the relay is not activated so the
daytime running light system does not operate. If the parking brake lever is then released (Parking brake SW off), a signal is
input to TERMINAL 11 of the relay.
This activates the daytime running light relay and the HEAD relay is turned to on, so the current flows from the HEAD MAIN
fuse to the HEAD relay (Point side) to HEAD LH LWR, HEAD RH LWR fuses to TERMINAL 2 of the headlights to TERMINAL
1 to TERMINAL 1 of the daytime running light relay to TERMINAL 2 to GROUND, causing the headlights to light up
(Headlights light up dimmer than normal brightness.). Once the daytime running light system operates and the headlights
light up, the headlights remain on even if the parking brake lever is pulled up (Parking brake SW on).
If the engine stalls and the ignition SW remains on, the headlights remain light up even through current is no longer output
from TERMINAL L of the generator. If the ignition SW is then turned off, the headlights go off.
If the engine is started with the parking brake lever released (Parking brake SW off), the daytime running light system
operates and headlights light up when the engine starts.
2. Headlight Operation
When the light control SW is switched to Head position and the dimmer SW is set to Low position, causing the daytime
running light relay and the HEAD relay to turn on, so the current flows from the HEAD MAIN fuse to HEAD relay (Coil side) to
TERMINAL 6 of the daytime running light relay to TERMINAL 7 to TERMINAL 12 of the light control SW to TERMINAL 11 to
GROUND. The current to HEAD relay (Point side) then flows to HEAD LH LWR, HEAD RH LWR fuses to TERMINAL 2 of the
headlights (Low) to TERMINAL 1 to TERMINAL 1 of the daytime running light relay to TERMINAL 2 to GROUND, causing
the headlights to light up at normal intensity.
When the light control SW is switched to Head position and the dimmer SW is set to High position, the signal from the
dimmer SW is input to the daytime running light relay. This activates the daytime running light relay and the HEAD relay is
turned on, so the current flows from the HEAD MAIN fuse to HEAD relay (Point side) to TERMINAL 1 of the DIMMER relay to
TERMINAL 2 to TERMINAL 13 of the daytime running light relay, activating the DIMMER relay. This causes current to flow
from TERMINAL 3 of the DIMMER relay to TERMINAL 5 to HEAD LH UPR, HEAD RH UPR fuses to TERMINAL 2 of the
headlights (High) to TERMINAL 1 to GROUND, causing the headlights to light up at high beam and the high beam indicator
light to light up.
When the dimmer SW is switched to Flash position, the signal from the dimmer SW is input to the daytime running light relay.
This activates the daytime running light relay and the HEAD relay is turned on, so the current flows from the HEAD MAIN
fuse to HEAD relay (Point side) to TERMINAL 1 of the DIMMER relay to TERMINAL 2 to TERMINAL 13 of the daytime
running light relay, activating the DIMMER relay, and also flows from the HEAD LH UPR, HEAD RH UPR fuses to
TERMINAL 2 of the headlights to TERMINAL 1 to GROUND, causing the headlights to light up at high beam and the high
beam indicator light to light up.
3. Automatic Light Control Operation (USA)
When the daytime running light is operating and the Automatic control sensor detects a decrease in the ambient light, the
automatic light control operation starts. At the same time, daytime running light relay is activated, so current flows from the
TAIL fuse to the TAIL relay (Coil side) to TERMINAL 14 of the daytime running light relay, and the HEAD MAIN fuse to the
HEAD relay (Coil side) to TERMINAL 6 of the daytime running light relay, activating both the TAIL relay and the HEAD relay,
so that the taillights and headlights light up.
When the automatic light control sensor detects an increase in the ambient light, the ignition SW is turned to off, the light
control SW is turned to Head position, and the automatic light control operation stops.

System Outline
With the ignition SW turned on, the current flows to TERMINAL 8 of the front wiper and washer SW, TERMINAL 2 of the front
wiper motor through the WIPER fuse, and the current flows to TERMINAL 2 of the washer motor through the WASHER fuse.
1. Low Speed Position
With the front wiper SW turned to LO position, the current flows from TERMINAL 8 of the front wiper and washer SW to
TERMINAL 7 to TERMINAL 1 of the front wiper motor to TERMINAL 5 to GROUND and causes to the front wiper motor to
run at low speed.
2. High Speed Position
With the front wiper SW turned to HI position, the current flows from TERMINAL 8 of the front wiper and washer SW to
TERMINAL 9 to TERMINAL 4 of the front wiper motor to TERMINAL 5 to GROUND and causes to the wiper motor to run at
high speed.
3. INT Position
With the front wiper SW turned to INT position, the wiper relay operates and the current which is connected by relay function
flows from TERMINAL 8 of the front wiper and washer SW to TERMINAL 5 to GROUND. This flow of current operates the
intermittent circuit and the current flows from TERMINAL 8 of the front wiper and washer SW to TERMINAL 7 to TERMINAL
1 of the front wiper motor to TERMINAL 5 to GROUND and the functions.
The intermittent operation is controlled by the charge/discharge function of the condenser installed in the relay, and the
intermittent time is controlled by a time control SW (w/ intermittent volume SW) to change the charging time of the
condenser.
4. MIST Position
With the front wiper SW turned to MIST position, the current flows from TERMINAL 8 of the front wiper and washer SW to
TERMINAL 7 to TERMINAL 1 of the front wiper motor to TERMINAL 5 to GROUND and causes to the front wiper motor to
run at low speed.
5. Washer Continuous Operation
With the front washer SW turned to on, the current flows from TERMINAL 2 of the front washer motor to TERMINAL 1 to
TERMINAL 4 of the front wiper and washer SW to TERMINAL 5 to GROUND and causes to the washer motor to run, and
the window washer jet operates. This causes the current to flow to washer continuous operation circuit in TERMINAL 8 of
the front wiper and washer SW to TERMINAL 7 to TERMINAL 1 of the front wiper motor to TERMINAL 5 to GROUND and
the washer operates continuously.

Rear Wiper and Washer
System Outline
When the ignition SW is turned on and glass hatch is closed, the current flows through the WASHER fuse to TERMINAL 2 of
the rear washer motor, the current flows through the RR WIPER fuse to IG relay (Point side) to TERMINAL 7 of the junction
SW and TERMINAL 3 of the rear wiper relay.
1. Rear Wiper Normal Operation
When the ignition SW is turned on, glass hatch is closed and rear wiper SW turned to ON position, the current flows through
the TERMINAL 3 of the rear wiper relay to TERMINAL 6 to TERMINAL 2 of the rear wiper SW to TERMINAL 5 to GROUND.
As a result, the rear wiper relay is operated, and the current flows through the TERMINAL 3 of the rear wiper relay to
TERMINAL 4 to TERMINAL 3 of the junction SW to rear wiper motor to TERMINAL 1 of the junction SW to GROUND,
causing the motor to operate the rear wiper.
2. Rear Wiper Intermittent Operation
When the ignition SW is turned on, glass hatch is closed and rear wiper SW turned to INT position, the current flows through
the TERMINAL 3 of the rear wiper relay to TERMINAL 2 to TERMINAL 1 of the rear wiper SW to TERMINAL 5 to GROUND.
As a result, the intermittent circuit of the relay operates and the rear wiper motor operates.
3. Washer Operation
With the ignition SW is turned on, glass hatch is closed and rear washer SW turned to ON and washer position, when the
rear wiper SW is turned further, the current flows through the WASHER fuse to TERMINAL 2 of the rear washer motor to
TERMINAL 1 to TERMINAL 3 of the rear washer SW to TERMINAL 5 to GROUND, so that the rear washer motor rotates
and the window washer emits a water, only while the switch is fully turned.
With the ignition SW turned on and the rear wiper and washer SW turned to OFF position, when the washer is turned ON (to
Wiper OFF side), current flows as above so that the rear washer motor rotates and the window washer emits water as well
as the wiper operates.

COROLLA MATRIX (EM00F0U)

Power Window
System Outline
When the ignition SW is turned on, the current flows through the GAUGE fuse to TERMINAL 1 of the P/W relay to
TERMINAL 2 to GROUND. This activates the relay and the current flows through the POWER fuse to TERMINAL 5 of the
relay to TERMINAL 3 to TERMINAL B of the power window master SW, TERMINAL 4 of the power window control SW front
RH and TERMINAL 3 of the power window control SW rear LH, RH.
1. Manual Operation (Driver’s Window)
With the ignition SW turned on and with the power window master SW (Front LH) in Up position, the current flowing to
TERMINAL B of the power window master SW flows to TERMINAL DU of the master SW to TERMINAL 4 of the power
window motor to TERMINAL 5 to TERMINAL DD of the master SW to TERMINAL E to GROUND and rotates the power
window motor in the up direction. The window ascends only while the SW is being pulled. In down operation, the flows of
current from TERMINAL B of the power window master SW to TERMINAL DD to TERMINAL 5 of the motor to TERMINAL 4
to TERMINAL DU of the master SW to TERMINAL E to GROUND, flowing in the opposite direction to manual up operation
and rotating the motor in reverse, thus opening the window.
2. Auto Down Operation (Driver’s Window)
When the front LH window control SW in the power window master SW is pushed strongly on the down side, current flows
from TERMINAL B of the master SW to TERMINAL DD to TERMINAL 5 of the power window motor to TERMINAL 4 to
TERMINAL DU of the master SW to TERMINAL E to GROUND. Because the hold circuit inside the master SW keeps the
relay on the down side activated, the power window motor continues operating even if the power window master SW is
released. When the driver’s window is fully opened, the hold circuit turns off and the relay on the down side turns off, and
auto down operation is completed.
3. Stopping of Auto Down Operation (Driver’s Window)
When the master SW (Front LH) is pulled to the up side during auto down operation, a ground circuit opens in the master
SW and current does not flow from TERMINAL DU of the master SW to TERMINAL E, so the motor stops, causing auto
down operation to stop. If the master SW is pulled continuously, the motor rotates in the up direction in manual up operation.
4. Manual Operation (Front RH Window)
With the power window control SW (Front RH) pulled to the up side, current flowing from TERMINAL 4 of the power window
control SW flows to TERMINAL 3 to TERMINAL 4 of the power window motor to TERMINAL 5 to TERMINAL 1 of the power
window control SW to TERMINAL 2 to TERMINAL PD of the master SW to TERMINAL E to GROUND and rotates the power
window motor (Front RH) in the up direction. Up operation continues only while the power window control SW is pulled to the
up side. When the window descends, the current flowing to the motor flows in the opposite direction, and the motor rotates in
reverse. When the window lock SW is pushed to the lock side, the ground circuit to the passenger’s window becomes open.
As a result, even if Open/Close operation of the passenger’s window is attempted, the current from TERMINAL E of the
power window master SW is not grounded and the motor does not rotate, so the passenger’s window can not be operated
and window lock occurs.
5. Manual Operation (Rear LH, Rear RH Window)
With the power window control SW (Rear LH, rear RH) pulled to the up side, current flowing from TERMINAL 3 of the power
window control SW flows to TERMINAL 4 to TERMINAL 5 of the power window motor to TERMINAL 4 to TERMINAL 2 of the
power window control SW to TERMINAL 1 to TERMINAL RLD, RRD of the master SW to TERMINAL E to GROUND and
rotates the power window motor (Rear LH, rear RH) in the up direction. Up operation continues only while the power window
control SW is pulled to the up side. When the window descends, the current flowing to the motor flows in the opposite
direction, and the motor rotates in reverse. When the window lock SW is pushed to the lock side, the ground circuit to the
passenger’s window becomes open. As a result, even if Open/Close operation of the passenger’s window is attempted, the
current from TERMINAL E of the power window master SW is not grounded and the motor does not rotate, so the
passenger’s window can not be operated and window lock occurs.

COROLLA MATRIX (EM00F0U)

System Outline
The current always flows to TERMINAL 1 of the integration relay through the DOOR fuse.
1. Manual Lock Operation
When the door lock control SW or door key lock and unlock SW are operated to Lock position, a lock signal is input to
TERMINAL (A) 9 or (A) 7 of the integration relay and causes the relay to function. The current flows from TERMINAL 1 of the
relay to TERMINAL 2 to the door lock motors to TERMINALS (A) 1 and 3 of the relay to TERMINAL 9 to GROUND and the
door lock motors locks the door.
2. Manual Unlock Operation
When the door lock control SW or door key lock and unlock SW are operated to Unlock position, an unlock signal is input to
TERMINAL (A) 8, (A) 6 or (A) 5 of the integration relay and causes the relay to function. The current flows from TERMINAL 1
of the relay to TERMINALS (A) 1 and 3 to the door lock motors to TERMINAL 2 of the relay to TERMINAL 9 to GROUND
and the door lock motors unlocks the door.
3. Double Operation Unlock Operation
When the door key lock and unlock SW LH is turned to the unlock side, only the driver’s door is unlocked. By turning the
door key lock and unlock SW LH to the unlock side, a signal is input to TERMINAL (A) 6 of the relay, and if the signal is input
again within 3 seconds by turning the SW to the unlock side again, current flows from TERMINAL 3 of the integration relay to
the door lock motors to TERMINAL 2 of the relay to TERMINAL 9 to GROUND, causing the door lock motors to operate and
unlock the doors.
4. Ignition Key Reminder Operation
∗ Operating door lock knob (Operation of door lock motors)
With the ignition key in the cylinder (Unlock warning SW on), when the door is opened and locked using door lock knob
(Door lock motor), the door is locked once but each door is unlocked soon by the function of the relay. As a result, the
current flows from TERMINAL 1 of the integration relay to TERMINALS (A) 1 and 3 to the door lock motors to
TERMINAL 2 of the relay to TERMINAL 9 to GROUND and unlocks all the doors.
∗ Operating door lock control SW or door key lock and unlock SW
With the ignition key in the cylinder (Unlock warning SW on), when the door is opened and locked using door lock
control SW or key SW, the door is locked once but each door is unlocked by the function of SW contained in motors,
and the signal is input to TERMINAL (A) 19 of the relay. According to this input signal, the current flows from TERMINAL
1 of the relay to TERMINALS (A) 1 and 3 to the door lock motors to TERMINAL 2 of the relay to TERMINAL 9 to
GROUND and unlocks all the doors.
∗ In case of key less lock
With the ignition the key in the cylinder (Unlock warning SW on), when the unlock function is disturbed for example
pushing the door lock knob etc., the door holds on lock condition. After closing the door, door courtesy SW inputs the
signal into TERMINAL 5 or 6 or (A) 13 of the integration relay. By this input signal, the relay works and current flows from
TERMINAL 1 of the relay to TERMINALS (A) 1 and 3 to the door lock motors to TERMINAL 2 of the relay to TERMINAL
9 to GROUND and unlocks all the doors.
5. Glass Hatch Open Operation
When the glass hatch opener SW on, the ignition SW at OFF position or the ignition SW at ON position and the vehicle
speed is less than approx. 16 km/h (9.6 mph), the glass hatch is opened.

Door lock control (Lock and unlock) and panic control (TVIP alarm and flash) is performed by remote control, without the
ignition key inserted in the door key cylinder, using low–power electrical waves emitted by a transmitter.
1. Wireless Door Lock or Unlock Normal Operation
With the ignition key not inserted into the ignition key cylinder (Unlock warning SW off) and all the doors completely closed,
when the lock or unlock button (Transmitter) is pushed, the door control receiver receives the electrical waves from the
transmitter, and sends a signal to the integration relay causing it to operate.
As a result, the integration relay judges whether the door is locked or unlocked based on the signal from the door lock motor
and door unlock detection SW, and sends a signal to switch the condition from lock to unlock or vice versa, causing the door
lock motor to operate.
2. Visual Confirmation of Lock or Unlock
If all doors indicate that they are locked after the lock command, parking lights and taillights will flash once. If any door
indicates that it is open after the unlock command, parking lights and taillights will flash twice.
3. Wireless Door Unlock Operation
Pushing the unlock button (Transmitter) once, driver’s door is unlocked. Furthermore, pushing the button again within 3
seconds, the other doors are unlocked.
4. Automatic Lock Operation
With the ignition key not inserted into the ignition key cylinder (Unlock warning SW off) and all the doors completely closed,
after pushing the button (Transmitter) to unlock all the doors, if a door is not opened within 30 seconds, all the doors will be
automatically relocked.
5. Glass Hatch Open Operation
With the ignition key not inserted into the ignition key cylinder, when the hatch button (Transmitter) is pushed, the door
control receiver receives the electrical waves from the transmitter, and sends a signal to the integration relay causing it to
operate.
As a result, the glass hatch is opened.
6. Wireless Control Stop Function
If a door is open (Door courtesy SW on), a signal is input from the door courtesy SW to the integration relay stopping
wireless door lock or unlock.
If the ignition key is in the ignition key cylinder (Unlock warning SW on), the unlock warning SW inputs a signal to the
integration relay stopping wireless door lock or unlock.
7. Repeat Function
In case an appropriate lock detection signal is not received after outputting a lock signal when pushing the lock button
(Transmitter), 1 seconds later, the integration relay output the lock signal again.
8. Remote Panic Operation
Panic will function when doors are locked or unlocked, open or closed. When the panic button (Transmitter) is pushed once,
theft alarm sounds and headlights and taillights flash. Then, the panic or the unlock button (Transmitter) is pushed once
more, sounding and flashing will stop. Panic will not function when ignition key is in ignition key cylinder.

COROLLA MATRIX (EM00F0U)

Electronically Controlled Transmission
System Outline
Previous automatic transaxle have selected each gear shift using mechanically controlled throttle hydraulic pressure,
governor hydraulic pressure and lock–up hydraulic pressure. The electronically controlled transmission, however, controls
the line pressure and lock–up pressure etc. electrically, through the solenoid valve. The engine control module controls each
solenoid valve based on the input signals from each sensor, which makes smooth driving possible by shift selection for each
gear that is most appropriate to the driving conditions at that time.
1. Gear Shift Operation
When driving, the engine warm up condition is input as a signal to TERMINAL THW of the engine control module from the
engine coolant temp. sensor and the vehicle speed signal from vehicle speed sensor is input to TERMINAL NT+ of the
engine control module. At the same time, the throttle valve opening signal from the throttle position sensor is input to
TERMINAL VTA (4WD) or TERMINALS VTA1 and VTA2 (2WD) of the engine control module as throttle angle signal.
Based on these signals, the engine control module selects the best shift position for the driving conditions and sends current
to the electronically controlled transmission solenoid.
2. Stop Light SW Circuit
If the brake pedal is depressed (Stop light SW on ) when driving in lock–up condition, a signal is input to TERMINAL STP of
the engine control module, the engine control module operates and continuity to the lock–up solenoid is cut.
3. Overdrive Circuit
∗ Overdrive on
When the engine is turned on from ignition off, the engine control module turns the O/D on. When the O/D main SW is
pushed while the O/D is off, a signal is input into TERMINAL ODMS of the engine control module, and the O/D is turned
on by the engine control module. In this case, the engine control module controls the gear shift according to the vehicle’s
driving condition, using the O/D range. At this time, the O/D OFF indicator light is off.
∗ Overdrive off
When the O/D main SW is pushed while the O/D is on, a signal is input into TERMINAL ODMS of the engine control
module, and the O/D is turned off. At this time, the current flows through the O/D OFF indicator light to TERMINAL ODLP
of the engine control module. As a result, the O/D OFF indicator light turns on, and the engine control module controls the
gear shift according to the vehicle’s driving condition, without using the O/D range.

COROLLA MATRIX (EM00F0U)

Cruise Control for 2ZZ–GE and 1ZZ–FE (4WD)
System Outline
The current is applied at all times through the STOP fuse to TERMINAL (A) 2 of the stop light SW.
With the ignition SW turned to on, the current flows through the MAIN fuse to AM2 fuse to ignition SW (IG2) to TERMINAL 2
of the combination meter and the current through the ECU–IG fuse flows to TERMINAL 2 of the cruise control ECU.
When the ignition SW is on and the CRUISE SW is turned on, a signal is input from TERMINAL 2 of the cruise control SW to
TERMINAL 11 of the cruise control ECU. As a result, the cruise control ECU functions and the current flows from the
ECU–IG fuse to TERMINAL 2 of the cruise control ECU to TERMINAL 16 of the cruise control ECU to GROUND, and the
cruise control system is in a condition ready for operation.
At the same time, the current through the MAIN fuse flows to AM2 fuse to ignition SW (IG2) to TERMINAL 2 of the CRUISE
indicator light to TERMINAL 14 to TERMINAL 5 of the cruise control ECU to TERMINAL 16 to GROUND, causing the
CRUISE indicator light to light up, indicating that cruise control is ready for operation.
1. Set Operation
When the CRUISE SW is turned on and the SET SW is pushed with the vehicle speed within the set limit (Approx. 40 km/h,
25 mph to 200 km/h, 124 mph), a signal is input to TERMINAL 11 of the cruise control ECU, and the vehicle speed at the
time the SET SW is released is memorized in the ECU as the set speed.
2. Set Speed Control
During cruise control driving, the ECU compares the set speed memorized in the ECU with the actual vehicle speed input
into TERMINAL 12 of the cruise control ECU from the combination meter, and controls the cruise control actuator to maintain
the set speed.
When the actual speed is lower than the set speed, the ECU causes the current to the cruise control actuator to flow from
TERMINAL 15 of the cruise control ECU to TERMINAL 1 of the cruise control actuator to TERMINAL 2 to TERMINAL 7 of
the cruise control ECU. As a result, the motor in the cruise control actuator is rotated to open the throttle valve and the
throttle cable is pulled to increase the vehicle speed. When the actual driving speed is higher than the set speed, the current
to the cruise control actuator flows from TERMINAL 7 of the ECU to TERMINAL 2 of the cruise control actuator to
TERMINAL 1 to TERMINAL 15 of the cruise control ECU.
This causes the motor in the cruise control actuator to rotate to close the throttle valve and return the throttle cable to
decrease the vehicle speed.
3. Coast Control
During cruise control driving, while the –/SET SW is on, the cruise control actuator returns the throttle cable to close the
throttle valve and decrease the driving speed. The vehicle speed when the –/SET SW is turned off is memorized, and the
vehicle continues at the new set speed.
4. Accel Control
During cruise control driving, while the +/RES SW is turned on, the cruise control actuator pulls the throttle cable to open the
throttle valve and increase the driving speed.
The vehicle speed when the +/RES SW is turned off is memorized and the vehicle continues at the new set speed.
5. Resume Control
The set speed is maintained even after the vehicle speed drops down to approx. 40 km/h (25 mph) or less. Therefore the
resume control will be effective when the vehicle speed reaches back to approx. 40 km/h (25 mph). After canceling the set
speed by the CANCEL SW, pushing the +/RES SW will cause the vehicle to resume the speed set before cancellation.
6. Manual Cancel Mechanism
If any of the following operations occurs during cruise control operation, the magnetic clutch of the actuator turns off and the
motor rotates to close the throttle valve and the cruise control is released.
∗ Placing the shift lever to positions except ”D” position (Park/Neutral position SW except ”D” position)(A/T), depressing the
clutch pedal (Cruise control clutch SW off)(M/T). ”Signal is not input to TERMINAL 4 of the ECU”
∗ Depressing the brake pedal (Stop light SW on). ”Signal input to TERMINAL 3 of the ECU”
∗ Pushing the CANCEL SW (CANCEL SW on). ”Signal input to TERMINAL 11 of the ECU”
∗ Pushing the CRUISE SW off ”signal input to TERMINAL 11 of the ECU”.
7. Tap–Up Control Function
When the difference between the actual vehicle speed and the set speed is less than 5 km/h (3 mph), the set speed can be
increased 1.6 km/h (1 mph) each time by operating the +/RES SW quickly within 0.6 seconds.
8. Tap–Down Control Function
When the difference between the actual vehicle speed and the set speed is less than 5 km/h (3 mph), the set speed can be
lowered 1.6 km/h (1 mph) each time by operating the –/SET SW quickly within 0.6 seconds.

176

COROLLA MATRIX (EM00F0U)

9. Auto Cancel Function
A) If any of the following operating conditions occurs during cruise control operation, the set speed is erased, current flow to
the magnetic clutch is stopped and the cruise control is released, (CRUISE SW turns off).
When this occurs, the ignition SW must be turned off once before the CRUISE SW will turn on.
∗ When current continues to flow to the motor inside the actuator in the throttle valve ”OPEN” direction.
∗ The motor does not operate despite the motor drive signal being output.
B) If any of the following operating conditions occurs during cruise control operation, the set speed is erased, current flow to
the magnetic clutch is stopped and the cruise control is released. (CRUISE SW turn off).
When this occurs, the cancel state is cleared as the CRUISE SW will turn on again.
∗ Over current to transistor driving the motor or the magnetic clutch.
∗ Open circuit in the magnetic clutch.
∗ Momentary interruption of vehicle speed signal.
∗ Short circuit in the cruise control SW.
∗ Short circuit of the ground when the control SW is turned ON.
C) If the following condition occurs during cruise control operation, the set speed is erased and the cruise control is released.
(The power to the magnetic clutch is cut off until the SET SW is ”ON” again.)
∗ When the power to the cruise system is momentarily cut off.
D) If the following condition occurs during cruise control operation, the cruise control is released. (The power to the magnetic
clutch is cut off until the SET SW is ”ON” again.)
∗ When the vehicle speed falls below the minimum speed limit, approx. 40 km/h (25 mph).
10. Automatic Transaxle Control Function (A/T)
∗ In overdrive. If the vehicle speed becomes lower than the overdrive cut speed (Set speed minus approx. 4 km/h, 2.5 mph)
during cruise control operation, such as driving up a hill, the overdrive is released and the power is increased to prevent a
reduction in vehicle speed.
∗ After releasing the overdrive, if the vehicle speed becomes higher than the overdrive return speed (Set speed minus
approx. 2 km/h, 1.2 mph) and the ECU judges by the signals from the actuator’s potentiometer that the upward slope has
finished, the overdrive is resumed after approximately 2 seconds.
∗ During cruise control driving, the cruise control operation signal is output from the cruise control ECU to the engine control
module. Upon receiving this signal, the engine control module changes the shift pattern to normal.
To maintain smooth cruise control operation (on a downward slope etc.), the lock–up release of the transaxle when the
idling point of the throttle position is ”ON” is forbidden.

Cruise Control for 1ZZ–FE (2WD)
System Outline
The cruise control system is a constant vehicle speed controller in which control of the switch on the instrument panel makes
it possible to automatically adjust the opening of the engine throttle valve without depressing of the accel pedal.
1. Set Operation
When the cruise control main SW is turned on, the system starts preparations necessary for the cruise control and turns on
the indicator light in the combination meter.
2. Set Speed Control
When the –/SET SW is operated with the cruise control main SW turned on during travelling, the constant vehicle speed is
controlled.
3. Coast Control
When the –/SET SW is kept turned on during cruise control travelling, the engine control module controls the throttle valve to
decelerate the vehicle. Every time the –/SET SW is turned on instantaneously, the vehicle speed is decelerated
approximately 1.6 km/h.
4. Accel Control
When the +/RES SW is kept turned on during cruise control travelling, the engine control module controls the throttle valve to
accelerate the vehicle. Every time the +/RES SW is turned on instantaneously, the vehicle speed is accelerated
approximately 1.6 km/h.
5. Resume Control
If the cruise control is cancelled, use of the +/RES SW accelerates the vehicle to the speed level used before canceling the
cruise control.
6. Manual Cancel Mechanism
If any of the following signals is input during cruise control travelling, the cruise control is cancelled.
∗ The stop light SW is turned on.
∗ The CANCEL SW is turned on.
∗ The cruise control main SW is turned off.
7. Auto Cancel Function
If any of the following conditions is encountered, the cruise control is automatically cancelled.
∗ The stop light SW wiring is faulty or short–circuited.
∗ The vehicle speed signal is faulty.
∗ The electronically controlled throttle malfunctions.
8. Overdrive Control Function
The overdrive control may be cancelled if the vehicle travels on the slope during cruise control travelling. After the overdrive
control has been cancelled it is decided that the slope is finished, the vehicle returns to the overdrive control mode again.

System Outline
The vehicle could be in an extreme over steering or under steering tendency due to unexpected accidents, road conditions,
vehicle speed, or by other external factors. In such a case, this system automatically controls the engine output and the
braking to each wheel, to decrease the extreme over steering and under steering.
∗ To decrease extreme over steering tendency
When the system determines that the over steering tendency is large, the system applies brakes to the outer wheels
according to the degree of over steering, and crates a moment towards the outer side of the vehicle, to decrease the
tendency of over steering. Also, when the brakes are applied, the vehicle speed decreases while the stability increases.
∗ To decrease extreme under steering tendency
When the system determines that the under steering tendency is large, the system applies brakes to the front or rear wheels
according to the degree of under steering, to decrease the tendency of under steering.
∗ TRAC OFF SW
TRAC OFF SW is only for two–wheel drive models. Four–wheel drive models is needless this SW.
The SW to send the traction control system into OFF mode. When the SW is pushed after starting the engine, the system will
be in OFF mode, and the TRAC OFF indicator light will turn on. When the SW is pushed again, the system will be in standby
mode. When the engine is stopped and re–started, regardless of the TRAC OFF SW, the system will be in standby mode.

Information to the driver

The VSC system informs the driver when the tire grip is about to exceed its grip capacity, by blinking the slip indicator light
and emiting an intermittent sound of the buzzer. Accordingly, the driver is informed to drive more gently.

COROLLA MATRIX (EM00F0U)

ABS and Tire Pressure Warning System
System Outline
ABS is a brake system designed to improve the operating ability and securing the stability of the vehicle by preventing the
lock–up of the vehicle by controlling the wheel cylinder pressure of all the four wheels at the time of sudden braking.
1. Input Signals
(1) Speed sensor signal
The speed of the wheels is detected and input to TERMINALS FL+, FR+, RL+, and RR+ of the skid control ECU with
actuator.
(2) Stop light SW signal
A signal is input to TERMINAL STP of the skid control ECU with actuator when brake pedal is depressed.
2. System Operation
When the wheels are locked–up, the solenoid inside the actuator is controlled by the signal from the skid control ECU with
actuator, and the brake fluid in the wheel cylinder will flow through the reservoir and reduce the hydraulic pressure.
While the ABS is in operation, as the skid control ECU with actuator always outputs the operation signal to the pump inside
the actuator, and the brake fluid stored inside the reservoir will be sucked up by the pump inside the actuator and returned to
the master cylinder.
When the hydraulic pressure of the wheel cylinder is decompressed or increased until the necessary hydraulic pressure, the
solenoid inside the actuator is controlled by the control signal from the skid control ECU with actuator and as a result,
hydraulic pressure of the wheel cylinder will be closed at both the master cylinder and reservoir sides routes, and the
hydraulic pressure of the wheel cylinder will be in the hold condition.
If increase of the hydraulic pressure volume of the wheel cylinder becomes necessary, the control signals from the skid
control ECU with actuator control the solenoid inside the actuator, to resume to the normal condition. Thus the brake fluid of
the master cylinder will be sent to the wheel cylinder and will increase the hydraulic pressure of the wheel cylinder. At this
time, in the case that the brake fluid is left in the reservoir, it will be sucked up by the pump inside the actuator and will be
sent to the wheel cylinder.

COROLLA MATRIX (EM00F0U)

SRS
NOTICE: When inspecting or repairing the SRS, perform service in accordance with the following precautionary instructions
and the procedure, and precautions in the Repair Manual applicable for the model year.

D Malfunction symptoms of the SRS are difficult to confirm, so the DTCs become the most important source of information
when troubleshooting. When troubleshooting the SRS, always inspect the DTCs before disconnecting the battery.

D Work must be started more than 90 seconds after the ignition SW is turned to the ”LOCK” position and the
negative (–) terminal cable is disconnected from the battery.
(The SRS is equipped with a back–up power source so that if work is started within 90 seconds from
disconnecting the negative (–) terminal cable of the battery, the SRS may deploy.)

D When the negative (–) terminal cable is disconnected from the battery, the memory of the clock and audio system will be
cleared. So before starting work, make a record of the contents in the audio memory system. When work is finished,
reset the audio systems as they were before and adjust the clock. Some vehicles have power tilt steering, power
telescopic steering, power seat and power outside rear view mirror which are all equipped with memory function.
However, it is not possible to make a record of these memory contents. So when the work is finished, it will be
necessary to explain it to your customer, and ask the customer to adjust the features and reset the memory. To avoid
erasing the memory in each system, never use a back–up power supply from outside the vehicle.

D Before repair, remove the airbag sensor if shocks are likely to be applied to the sensor during repair.

D Do not expose the following parts directly to hot air or flame;

D Even in cases of a minor collision where the SRS does not deploy, the following parts should be inspected;

D Never use SRS parts from another vehicle. When replacing parts, replace with new parts.

D For the purpose of reuse, never disassemble and repair the following parts.

D If the following parts have been dropped, or have cracks, dents and other defects in their case, bracket, and connector,
replace with new one.

D Use a volt/ohmmeter with high impedance (10 kΩ/V minimum) for troubleshooting electrical circuits of the system.

D Information labels are attached to the periphery of the SRS components. Follow the instructions of the notice.

D After work on the SRS is completed, check the SRS warning light.

D If the vehicle is equipped with a mobile communication system, refer to the precaution in the IN section of the Repair
Manual.

SRS
System Outline
The SRS is a driver and front passenger protection device which has a supplemental role to the seat belts.
When the ignition SW is turned to ON, current from the MAIN fuse flows to AM2 fuse to ignition SW (IG2) to TERMINAL (B)
21 of the airbag sensor assembly.
If an accident occurs while driving, when the frontal impact exceeds a set level, the current from the TERMINAL (B) 21 of the
airbag sensor assembly flows to TERMINALS (B) 5, (B) 8, (B) 4, (B) 1, (A) 2 and (C) 4 of the airbag sensor assembly to the
airbag squibs and the pretensioners to TERMINALS (B) 6, (B) 7, (B) 3, (B) 2, (A) 1 and (C) 5 of the airbag sensor assembly
to TERMINAL (B) 25, (B) 26 or BODY GROUND to GROUND, so that the current flows to the front airbag squibs and the
pretensioners, and causes them to operate.
When the side impact also exceeds a set level, the current from the TERMINAL (B) 21 of the airbag sensor assembly flows
to TERMINALS (A) 9, (C) 7, (A) 7, (C) 9 of the airbag sensor assembly to the side airbag squibs and curtain shield airbag
squibs to TERMINALS (A) 10, (C) 6, (A) 6, (C) 10 of the airbag sensor assembly to TERMINAL (B) 25, (B) 26 or BODY
GROUND to GROUND, causing side airbag squibs to operate.
The airbag stored inside the steering wheel pad is instantaneously expanded to soften the shock to the driver.
The airbag stored inside the passenger’s instrument panel is instantaneously expanded to soften the shock to the front
passenger.
Side airbags are instantaneously expanded to soften the shock of side to the driver and front passenger.
The curtain shield airbag can reduce impact on the head of the front and rear passengers and reduce risk or injury.
The pretensioners make sure of the seat belt restrainability.

System Outline
When the ignition SW is turned to ON position, the current from the ECU–IG fuse flows to TERMINAL 5 of the shift lock
control ECU.
Shift Lock Mechanism
With the ignition SW at ON position, when a signal that the brake pedal is depressed (Stop light SW on) and a signal that the
shift lever is put in P position is input to the ECU, the ECU operates and the current flows from TERMINAL 5 of the ECU to
TERMINAL SLS+ of the shift lock solenoid to TERMINAL SLS– to TERMINAL 1 of the ECU to GROUND. This causes the
shift lock solenoid to turn on (Plate stopper disengages) and the shift lever can shift into position other than P.

COROLLA MATRIX (EM00F0U)

System Outline
The current is applied at all times to TERMINAL 1 of the combination meter through the DOME fuse.
When the ignition SW is turned to ON position, the current flows to TERMINAL 21 of the combination meter through the
GAUGE fuse. When the light control SW is turned to Tail or Head position, current is applied to TERMINAL 4 of the
combination meter through the TAIL fuse via the TAIL relay (USA) or light control SW (Canada).
1. Light Reminder System
When the light control SW is in Tail or Head position, the ignition SW turned to OFF from ON position, and the driver’s door
opened (Door courtesy SW on), the current flows to TERMINAL 21 of the combination meter stops. As a result, the
combination meter is activated and current flows from TERMINAL 1 of the combination meter to TERMINAL 40 to GROUND,
the buzzer in the combination meter goes on to remind the light is lighting up.
2. Key Reminder System
When the driver door is opened with the ignition SW off and ignition key remaining in the key cylinder (Unlock warning SW
on), a signal is input from the unlock warning SW to TERMINAL 15 of the combination meter, and from the door courtesy SW
front LH to TERMINAL 26 of the combination meter. As a result, the buzzer in the combination meter goes on and warns the
driver that the key is remaining in the key cylinder.

Seat Belt Warning
System Outline
Current is always applied from the DOME fuse to TERMINAL 1 of the combination meter. When the ignition SW is turned to
ON position, the current from the GAUGE fuse flows to TERMINAL 21 of the combination meter and flows to TERMINAL 4 of
the front passenger seat belt warning light.
Seat Belt Warning System
When the ignition SW turned on, a signal is input to the combination meter. To determine whether the driver has fastened the
seat belt, a signal is input from the buckle SW LH to TERMINAL 31 of the combination meter. When the seat belt is not
fastened, the seat belt warning light in the combination meter blinks, and emits a warning sound.
In addition, the front passenger is recognized by a sensor (Occupant detection sensor) is installed in the front passenger
seat, and determines whether the seat belt is fastened. When not fastened, the signals from the occupant detection sensor
is input to TERMINAL 37 of the combination meter, and the front passenger seat belt warning light blinks.

System Outline
The current is applied at all times through the RDI FAN fuse to TERMINAL 5 of the FAN NO.1 relay.
When the ignition SW is turned on, the current flows through the ECU–IG fuse to FAN NO.1 relay (Coil side) to TERMINAL
CF of the engine control module. At the same time as this current flow, the current from ECU–IG fuse flows to the FAN NO.2
relay (Coil side) to TERMINAL 3 of the pressure SW.
1. Low Speed Operation
When the A/C system is operating, the FAN NO.1 Relay is turned on. As a result, the current flows from the RDI FAN fuse to
FAN NO.1 relay (Point side) to TERMINAL 2 of the radiator fan motor to TERMINAL 1 to TERMINAL 3 of the FAN NO.2 relay
to TERMINAL 4 to TERMINAL 2 of the radiator fan resistor to TERMINAL 1 to GROUND, and the radiator fan motor rotates
at low speed.
2. High Speed Operation
When the pressure SW is on or engine control module operated, the FAN NO.1 and NO.2 relay is turned on. As a result, the
current flows from the RDI FAN fuse to FAN NO.1 relay (Point side) to radiator fan motor to TERMINAL 3 of the FAN NO.2
Relay to TERMINAL 5 to GROUND, and the radiator fan motor rotates at high speed.

When the ignition SW is turned on, the current flows through the GAUGE fuse to TERMINAL 2 of the HTR relay to
TERMINAL 1 to TERMINAL 6 of the blower SW.

1. Heater Blower Motor Operation

∗ Low speed operation
When the blower SW is moved to LO position, the current flows to TERMINAL 6 of the blower SW to TERMINAL 5 to
GROUND, causing the HTR relay to turn on. This causes the current flows from the HEATER fuse to TERMINAL 5 of
the HTR relay to TERMINAL 3 to the blower motor to the blower resistor to GROUND, rotating the blower motor at low
speed.

∗ Medium speed operation (Operation at M1, M2)

When the blower SW is moved to M1 position, the current flows to TERMINAL 6 of the blower SW to TERMINAL 5 to
GROUND, causing the HTR relay to turn on. This causes the current flows from the HEATER fuse to TERMINAL 5 of
the HTR relay to TERMINAL 3 to the blower motor to the blower resistor to TERMINAL 2 of the blower SW to
TERMINAL 5 to GROUND. At this time, the blower resistance of the blower resistor is smaller than at low speed, so the
blower motor rotates at medium low speed.
When the blower SW is moved to M2 position, the current flows through the HTR relay to the blower motor to the blower
resistor to TERMINAL 1 of the blower SW to TERMINAL 5 to GROUND. At this time, resistance of the blower resistor is
smaller than at M1 position, so the blower motor rotates at medium high speed.

∗ High speed operation

When the blower SW is moved to HI position, the current flows to TERMINAL 6 of the blower SW to TERMINAL 5 to
GROUND, causing the HTR relay to turn on.
This causes the current flows from the HEATER fuse to TERMINAL 5 of the HTR relay to TERMINAL 3 to the blower
motor to TERMINAL 4 of the blower SW to TERMINAL 5 to GROUND, rotating the blower motor at high speed.

System Outline
Current is applied at all times through the HEATER fuse to TERMINAL 5 of the HTR relay.
When the ignition SW is turned on, the current flows through the GAUGE fuse to TERMINAL 2 of the HTR relay to
TERMINAL 1 to TERMINAL 6 of the blower SW.

1. Heater Blower Motor Operation

∗ Low speed operation
When the blower SW is moved to LO position, the current flows to TERMINAL 6 of the blower SW to TERMINAL 5 to
GROUND, causing the HTR relay to turn on. This causes the current flows from the HEATER fuse to TERMINAL 5 of
the HTR relay to TERMINAL 3 to the blower motor to the blower resistor to GROUND, rotating the blower motor at low
speed.

∗ Medium speed operation (Operation at M1, M2)

When the blower SW is moved to M1 position, the current flows to TERMINAL 6 of the blower SW to TERMINAL 5 to
GROUND, causing the HTR relay to turn on. This causes the current flows from the HEATER fuse to TERMINAL 5 of
the HTR relay to TERMINAL 3 to the blower motor to the blower resistor to TERMINAL 2 of the blower SW to
TERMINAL 5 to GROUND. At this time, the blower resistance of the blower resistor is smaller than at low speed, so the
blower motor rotates at medium low speed.
When the blower SW is moved to M2 position, the current flows through the HTR relay to the blower motor to the blower
resistor to TERMINAL 1 of the blower SW to TERMINAL 5 to GROUND. At this time, resistance of the blower resistor is
smaller than at M1 position, so the blower motor rotates at medium high speed.

∗ High speed operation

When the blower SW is moved to HI position, the current flows to TERMINAL 6 of the blower SW to TERMINAL 5 to
GROUND, causing the HTR relay to turn on.
This causes the current flows from the HEATER fuse to TERMINAL 5 of the HTR relay to TERMINAL 3 to the blower
motor to TERMINAL 4 of the blower SW to TERMINAL 5 to GROUND, rotating the blower motor at high speed.
2. Air Conditioning Operation
When the blower SW is set on, the current flows from the HEATER fuse to the HTR relay (Point side) to the A/C fuse to the
TERMINAL 8 of the A/C SW and TERMINAL 2 of the defroster mode SW. If the A/C SW or the defroster mode SW is turned
on, at this time a signal is input into the engine control module. This activates the engine control module and M/G CLT relay.
So that current flows from the A/C fuse to M/G CLT relay (Point side) to A/C magnetic clutch. Causing the compressor to
operate.
3. DEF or FOOT & DEF Synchronized Control Function
When the blower SW is on and the heater control lever (Air vent mode control lever) turned to DEF or FOOT & DEF position,
it causes A/C to run and the air inlet control SW to be at FRESH position whether A/C SW is on or not.
