HOW TO USE THIS MANUAL B
This manual provides information on the electrical circuits installed on vehicles by

dividing them into a circuit for each system.
The actual wiring of each system circuit is shown from the point where the power
source is received from the battery as far as each ground point. (All circuit
diagrams are shown with the switches in the OFF position.)
When troubleshooting any problem, first understand the operation of the circuit
where the problem was detected (see System Circuit section), the power source
supplying power to that circuit (see Power Source section), and the ground points
(see Ground Point section). See the System Outline to understand the circuit
operation.
When the circuit operation is understood, begin troubleshooting of the problem

circuit to isolate the cause. Use Relay Location and Electrical Wiring Routing
sections to find each part, junction block and wiring harness connectors, wiring
harness and wiring harness connectors, splice points, and ground points of each
system circuit. Internal wiring for each junction block is also provided for better
understanding of connection within a junction block.
Wiring related to each system is indicated in each system circuit by arrows
(from__, to__). When overall connections are required, see the Overall Electrical
Wiring Diagram at the end of this manual.

[O] SYSTEM OUTLINE
Current is applied at all times through the STOP fuse to TERMINAL 2 of the stop light SW.
When the ignition SW is turned on, current flows from the GAUGE fuse to TERMINAL 8 of the light failure sensor, and also flows
through the rear lights warning light to TERMINAL 4 of the light failure sensor.
STOP LIGHT DISCONNECTION WARNING
When the ignition SW is turned on and the brake pedal is pressed (Stop light SW on), if the stop light circuit is open, the current
flowing from TERMINAL 7 of the light failure sensor to TERMINALS 1, 2 changes, so the light failure sensor detects the
disconnection and the warning circuit of the light failure sensor is activated.
As a result, the current flows from TERMINAL 4 of the light failure sensor to TERMINAL 11 to GROUND and turns the rear lights
warning light on. By pressing the brake pedal, the current flowing to TERMINAL 8 of the light failure sensor keeps the warning
circuit on and holds the warning light on until the ignition SW is turned off.

SYSTEM OUTLINE
The engine control system utilizes a microcomputer and maintains overall control of the engine, transmission etc. An outline
of the engine control is given here.
1. INPUT SIGNALS
(1) Engine coolant temp. signal circuit
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. The engine coolant temp. is input into TERMINAL THW of the engine
control module as a control signal.
(2) Intake air temp. signal circuit
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) Oxygen sensor signal circuit
The oxygen density in the exhaust emission is detected and is input as a control signal from the heated oxygen sensors
to TERMINALS OX1A, OX2A, OX1B, OX2B of the engine control module.
(4) RPM signal circuit
The camshaft position is detected by the camshaft position sensor and is input into TERMINAL G2 of the engine control
module as a control signal. Also, the engine RPM is detected by the crankshaft position sensor and the signal is input
into TERMINAL NE+ of the engine control module.
(5) Throttle position sensor signal circuit
The throttle position sensor detects the throttle valve opening angle as a control signal, which is input into TERMINALS
VTA1, VTA2 of the engine control module.
(6) Vehicle speed circuit
The vehicle speed sensor (Combination meter) detects the vehicle speed, and the signal is input into TERMINAL SPD
of the engine control module via the combination meter.
(7) Battery signal circuit
Voltage is constantly applied to TERMINAL BATT of the engine control module. When the ignition SW is turned on, the
voltage for engine control module start up power supply is applied through the EFI relay, to TERMINALS +B, +B2 of the
engine control module. The current from the IGN fuse flows to TERMINAL IGSW of the engine control module, and
voltage is constantly applied to TERMINAL +BM.
(8) Intake air volume signal circuit
The 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.
(9) Stop light SW signal circuit
The stop light SW is used to detect whether the vehicle is braking or not, and the signal is input into TERMINAL STP of
the engine control module as a control signal.
(10) Starter signal circuit
To confirm whether the engine is cranking, the voltage applied to the starter motor when the engine is cranking is
detected, and is input into TERMINAL STA of the engine control module as a control signal.
(11) Engine knock signal circuit
Engine knocking is detected by the knock sensors, and is input into TERMINALS KNK1, KNK2 of the engine control
module as a control signal.
84
2. CONTROL SYSTEM
∗ SFI system
The SFI system monitors the engine condition through the signals input from each sensors to the engine control module.
The control signal is sent to the engine control module TERMINALS #1, #2, #3, #4, #5, #6, #7, #8 to operate the injector
(Fuel injection). The SFI system controls the fuel injection by the engine control module in response to the driving
conditions.
∗ ESA system
The ESA system monitors the engine condition through the signals input from each sensors to the engine control module.
The best ignition timing is decided according to this data and the data memorized in the engine control module. The
control signal is output to TERMINALS IGT1, IGT2, IGT3, IGT4, IGT5, IGT6, IGT7, IGT8, and these signals control the
igniter to provide the best ignition timing.
∗ Heated oxygen sensor heater control system
The heated oxygen sensor heater control system turns the heater on when the intake air volume is low (Temp. of exhaust
emission is low), and warms up the heated oxygen sensors to improve their detection performance. The engine control
module evaluates the signals from each sensors, and outputs current to TERMINALS HT1A, HT2A, HT1B, HT2B to
control the heater.
∗ Fuel pump control system
The engine control module supplies current to TERMINAL FPR, and controls the operation speed of the fuel pump with
the F/PMP relay.
∗ ETCS–i
The ETCS–i controls the engine output at its optimal level in accordance with the opening of the accelerator pedal, under
all driving conditions.
3. DIAGNOSIS SYSTEM
When there is a malfunction in the engine control module signal system, the malfunctioning system is recorded in the
memory. The malfunctioning system can be found by reading the code displayed on the malfunction indicator lamp.
4. FAIL–SAFE SYSTEM
When a malfunction has occurred in any system, there is a possibility of causing engine trouble due to continued control
based on that system. In that case, the fail–safe system either controls the system using the data (Standard values)
recorded in the engine control module memory, or else stops the engine.

SYSTEM OUTLINE
The engine control system utilizes a microcomputer and maintains overall control of the engine, transmission etc. An outline
of the engine control is given here.
1. INPUT SIGNALS
(1) Engine coolant temp. signal circuit
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. The engine coolant temp. is input into TERMINAL THW of the engine
control module as a control signal.
(2) Intake air temp. signal circuit
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) Oxygen sensor signal circuit
The oxygen density in the exhaust emission is detected and is input as a control signal from the heated oxygen sensors
to TERMINAL OX2B of the engine control module.
(4) RPM signal circuit
The camshaft position is detected by the camshaft position sensor and is input into TERMINAL G2 of the engine control
module as a control signal. Also, the engine RPM is detected by the crankshaft position sensor and the signal is input
into TERMINAL NE+ of the engine control module.
(5) Throttle position sensor signal circuit
The throttle position sensor detects the throttle valve opening angle as a control signal, which is input into TERMINAL
VTA of the engine control module.
(6) Vehicle speed circuit
The vehicle speed sensor (Combination meter) detects the vehicle speed, and the signal is input into TERMINAL SP1 of
the engine control module via the combination meter.
(7) Battery signal circuit
Voltage is constantly applied to TERMINAL BATT of the engine control module. When the ignition SW is turned on, the
voltage for engine control module start up power supply is applied through the EFI relay, to TERMINAL +B of the engine
control module.
(8) Intake air volume signal circuit
The 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.
(9) Stop light SW signal circuit
The stop light SW is used to detect whether the vehicle is braking or not, and the signal is input into TERMINAL STP of
the engine control module as a control signal.
(10) Starter signal circuit
To confirm whether the engine is cranking, the voltage applied to the starter motor when the engine is cranking is
detected, and is input into TERMINAL STA of the engine control module as a control signal.
(11) Engine knock signal circuit
Engine knocking is detected by the knock sensors, and is input into TERMINALS KNK1, KNK2 of the engine control
module as a control signal.
(12) A/C SW signal system
The operating voltage of the A/C magnetic clutch is detected and input in the form of a control signal to TERMINAL AC1
of the engine control module.
(13) 4WD signal system
Whether or not the vehicle is operating in 4WD mode is determined, and a control signal is input to TERMINAL 4WD of
the engine control module.
(14) Air fuel ratio signal system
The air fuel ratio is detected and input as a control signal into TERMINAL AF1+ of the engine control module.
93
2. CONTROL SYSTEM
∗ SFI system
The SFI system monitors the engine condition through the signals input from each sensors to the engine control module.
The control signal is sent to the engine control module TERMINALS #10, #20, #30, #40, #50, #60 to operate the injector
(Fuel injection). The SFI system controls the fuel injection by the engine control module in response to the driving
conditions.
∗ ESA system
The ESA system monitors the engine condition through the signals input from each sensors to the engine control module.
The best ignition timing is decided according to this data and the data memorized in the engine control module. The
control signal is output to TERMINALS IGT1, IGT2, IGT3 and these signals control the igniter to provide the best ignition
timing.
∗ Heated oxygen sensor heater control system
The heated oxygen sensor heater control system turns the heater on when the intake air volume is low (Temp. of exhaust
emission is low), and warms up the heated oxygen sensors to improve their detection performance. The engine control
module evaluates the signals from each sensors, and outputs current to TERMINAL HT2B to control the heater.
3. DIAGNOSIS SYSTEM
When there is a malfunction in the engine control module signal system, the malfunctioning system is recorded in the
memory. The malfunctioning system can be found by reading the code displayed on the malfunction indicator lamp.
4. FAIL–SAFE SYSTEM
When a malfunction has occurred in any system, there is a possibility of causing engine trouble due to continued control
based on that system. In that case, the fail–safe system either controls the system using the data (Standard values)
recorded in the engine control module memory, or else stops the engine.

SYSTEM OUTLINE
With the ignition SW turned on, the current flows to TERMINAL 9 of the integration relay through ECU IG fuse.
Voltage is applied at all times to TERMINAL 6 of the integration relay through the TAIL fuse, and through the H–LP relay coil
side.
1. NORMAL LIGHTING OPERATION
<Turn taillight on>
With the light control SW turned to TAIL position, a signal is input into the integration relay. Due to this signal, the current
flowing to TERMINAL 6 of the relay flows to TERMINAL 14 of the light control SW to TERMINAL 16 to GROUND, and
taillights to turn on.
<Turn headlight on>

With the light control SW turned to HEAD position, a signal is input into the integration relay. Due to this signal, the current
flowing to the relay flows to TERMINAL 13 of the light control SW to TERMINAL 16 to GROUND in the headlight circuit, and
causes taillight and H–LP relay to turn the lights on. The taillight circuit is same as above.
2. LIGHT AUTO TURN OFF OPERATION
With light on and ignition SW turned off (Input signal goes to TERMINAL 9 of the relay), when the driver’s door is opened
(Input signal goes to TERMINAL 14 of the relay), the relay operates and the current is cut off which flows from TERMINAL 6
and through the H–LP relay coil side of the relay to taillight circuit and headlight circuit.
As a result, all lights are turned off automatically.

SYSTEM OUTLINE
The electronically controlled transmission electrically controls the, throttle pressure, lock–up pressure, and accumulator
pressure etc. through the solenoid valve.
The electronically controlled transmission is a system which precisely controls the gear shift timing and lock–up timing in
response to the vehicle’s driving conditions and the engine condition detected by various sensors. It makes smooth driving
possible by shift selection of the gear which is the most appropriate to the driving conditions at that time, and by preventing
downing, squat and gear shift shock when starting off.
1. GEAR SHIFT OPERATION
When driving, the engine warm up condition is input as a control signal from the engine coolant temp. sensor to TERMINAL
THW of the engine control module, and the vehicle speed is input to TERMINAL SP2+ of the engine control module from the
vehicle speed sensor. At the same time, the throttle valve opening signal from the throttle position sensor is input to
TERMINALS VTA, VTA2 of the engine control module as a 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. LOCK–UP OPERATION
When the engine control module decides based on each signal that the lock–up condition has been met, the current flows
from the engine control module TERMINAL SL to TERMINAL 7 of the electronically controlled transmission solenoid to
GROUND.
3. STOP LIGHT SW CIRCUIT
If the brake pedal is depressed (Stop light SW on) when driving in lock–up position, a signal is input to TERMINAL STP of
the engine control module. As a result, the engine control module cuts the current to the solenoid to release the lock–up.
4. OVERDRIVE CIRCUIT
∗ O/D main SW on
When the O/D main SW is switched to ON position, a signal is input to TERMINAL ODMS of the engine control module,
and enables shift change to the overdrive range, through the control of the engine control module.
∗ O/D main SW off
When the O/D main SW is switched to OFF position, a signal is input to TERMINAL ODMS of the engine control module,
and prohibits shift change to the overdrive range through the control of the engine control module. When in the overdrive
range already, shift down is made.

SYSTEM OUTLINE
Previous automatic transmissions have selected each gear shift using mechanically controlled throttle hydraulic pressure,
governor hydraulic pressure and lock-up hydraulic pressure. The electronically controlled transmission, however, electrically
controls the governor pressure and lock-up sensor through the solenoid valve. Control of the solenoid valve by the engine
control module based on the input signals from each sensor makes smooth driving possible by shift selection for each gear
which is most appropriate to the driving conditions at that time.
1. GEAR SHIFT OPERATION
During driving, the engine control module selects the shift for each gear which is most appropriate to the driving conditions,
based on input signals from the engine coolant temp. sensor to TERMINAL THW of the engine control module and also the
input signals to TERMINAL SP2+ of the engine control module from the vehicle speed sensor devoted to the electronically
controlled transmission. Current is then output to the electronically controlled transmission solenoid. When shifting to 1st
speed, current flows from TERMINAL S1 of the engine control module to TERMINAL 4 of the electronically controlled
transmission solenoid to GROUND, and continuity to the No.1 solenoid causes the shift.
For 2nd gear, current flows from TERMINAL S1 of the engine control module to TERMINAL 4 of the electronically controlled
transmission solenoid to GROUND, and from TERMINAL S2 of the engine control module to TERMINAL 8 of the
electronically controlled transmission solenoid to GROUND. And continuity to solenoid No.1 and No.2 causes the shift.
For 3rd gear, there is no continuity to No.1 solenoid, only to No.2 causing the shift. Shifting into 4th gear (Overdrive) takes
place when there is no continuity to either No.1 or No.2 solenoid.
2. LOCK-UP OPERATION
When the engine control module judges from each signal that lock-up operation conditions have been met, current flows
from TERMINAL SL of the engine control module to TERMINAL 7 of the electronically controlled transmission solenoid to
GROUND, causing continuity to the lock-up solenoid and causing lock-up operation.
3. STOP LIGHT SW CIRCUIT
If the brake pedal is depressed (Stop light SW on) when driving in lock–up position, a signal is input to TERMINAL STP of
the engine control module. As a result, the engine control module cuts the current to the solenoid to release the lock–up.
4. OVERDRIVE CIRCUIT
∗ O/D main SW on
When the O/D main SW is switched to ON position, a signal is input to TERMINAL ODMS of the engine control module,
and enables shift change to the overdrive range, through the control of the engine control module.
∗ O/D main SW off
When the O/D main SW is switched to OFF position, a signal is input to TERMINAL ODMS of the engine control module,
and prohibits shift change to the overdrive range through the control of the engine control module. When in the overdrive
range already, shift down is made.

SYSTEM OUTLINE
This system controls the respective brake fluid pressures acting on the disc brake cylinders of the right front wheel, left front
wheel, and rear wheels when the brakes are applied in a panic stop so that the wheels do not lock.
This results in improved directional stability and steerability during panic braking.
1. INPUT SIGNAL
(1) Speed sensor signal
The speed of the wheels is detected and input to TERMINALS FL+, FR+, RL+ and RR+ of the ABS actuator with ECU.
(2) Stop light SW signal
A signal is input to TERMINAL STP of the ABS actuator with ECU when the brake pedal is depressed.
2. SYSTEM OPERATION
During sudden braking, the ABS actuator with ECU which has signals input from each sensor lets the hydraulic pressure
acting on each wheel cylinder escape to the reservoir.
The pump inside the ABS actuator with ECU is also operating at this time and it returns the brake fluid from the reservoir to
the master cylinder, thus preventing locking of vehicle wheels.
If the ABS actuator with ECU judges that the hydraulic pressure acting on the wheel cylinder is insufficient, the current acting
on the solenoid is controlled and the hydraulic pressure is increased.
Holding of the hydraulic pressure is also controlled by the ECU, by the same method as above, by repeated pressure
reduction. Holding and increase are repeated to maintain vehicle stability and to improve steerability during sudden braking.

CRUISE CONTROL (2UZ–FE)
SYSTEM OUTLINE
The cruise control system is a constant vehicle speed controller which controls the opening angle of the engine throttle valve
by the SW, and allows driving at a constant speed without depressing the accelerator pedal.
SET CONTROL
When the SET/COAST SW is operated while traveling with the main SW on, the speed when the SET/COAST SW is
operated to off is memorized, and the vehicle speed is controlled at that speed.
COAST CONTROL
When the SET/COAST SW is operated to on, the cruise control opening angle requirement is turned to 0 to decrease the
vehicle speed, and the speed when the SET/COAST SW is operated to off is memorized, and the vehicle speed is controlled
at that speed.
Furthermore, every time the SET/COAST SW is operated momentarily (Approx. 0.5 sec.) to on, the memorized vehicle
speed is decreased by approx. 1.6 km/h (1.0 mph).
ACCEL CONTROL
When the RES/ACC SW is operated to on, the throttle motor rotates the throttle valve to open direction to increase the
vehicle speed, and the speed when the RES/ACC SW is operated to off is memorized, and the vehicle speed is controlled at
that speed.
Furthermore, every time the RES/ACC SW is operated momentarily (Approx. 0.5 sec.) to on, the memorized vehicle speed is
increased by approx. 1.6 km/h (1.0 mph).
MANUAL CANCEL MECHANISM
If any of the following signals are input during cruise control traveling, the current to the motor flows in the direction to close
the throttle valve, and cancel the cruise control.
(1) Stop lamp SW is on (Brake pedal is depressed)
(2) The CANCEL SW of the control SW is on
(3) CRUISE SW is off
RESUME CONTROL
After canceling the cruise control (Except when the main SW is off) if the vehicle speed is above the minimum speed limit
(Approx. 40km/h, 25mph), operating the RES/ACC SW to on from off will cause the system to accelerate and resume to the
vehicle speed before manual cancellation.
OVERDRIVE FUNCTION
The overdrive may be cut on an uphill grade, while traveling with the cruise control.
After the overdrive is cut, if the vehicle speed reaches the overdrive resume speed (Set speed minus 2 km/h (1.2 mph) ), and
if the system determines that the uphill grade has finished, the overdrive will resume after the overdrive timer operation.
AUTO CANCEL OPERATION
If any of the following conditions are detected, the set speed is erased and the control is canceled.
(1) Disconnection and/or short in the stop light SW
(2) Malfunction in the vehicle speed signal
(3) Malfunction in the electronic throttle parts
(4) Malfunction in the stop light SW input circuit
(5) Malfunction in the cancel circuit
(6) The actual vehicle speed becomes slower than the minimum speed limit
(7) The actual vehicle speed becomes –16 km/h (10 mph) slower than the set speed

SRS
NOTICE: When inspecting or repairing the SRS, perform the operation in accordance with the following precautionary
instructions and the procedure and precautions in the Repair Manual for the applicable model year.
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.
Work must be started after 90 seconds from when the ignition switch 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 be deployed.)
When the negative (–) terminal cable is disconnected from the battery, the memory of the clock and audio system will be
canceled. So before starting work, make a record of the contents memorized in the audio memory system. When work is
finished, reset the audio systems as they were before and adjust the clock. To avoid erasing the memory in each
memory system, never use a back–up power supply from outside the vehicle.
Before repairs, remove the airbag sensor if shocks are likely to be applied to the sensor during repairs.
Do not expose the steering wheel pad, front passenger airbag assembly, seat belt pretensioner, center airbag sensor
assembly or front airbag sensor assembly directly to hot air or flames.
Even in cases of a minor collision where the SRS does not deploy, the steering wheel pad, front passenger airbag
assembly, seat belt pretensioner, center airbag sensor assembly and front airbag sensor assembly should be inspected.
Never use SRS parts from another vehicle. When replacing parts, replace them with new parts.
Never disassemble and repair the steering wheel pad, front passenger airbag assembly, seat belt pretensioner, center
airbag sensor assembly or front airbag sensor assembly in order to reuse it.
If the steering wheel pad, front passenger airbag assembly, seat belt pretensioner, center airbag sensor assembly or
front airbag sensor assembly has been dropped, or if there are cracks, dents or other defects in the case, bracket or
connector, replace them with new ones.
Use a volt/ohmmeter with high impedance (10 kΩ/V minimum) for troubleshooting the system’s electrical circuits.
Information labels are attached to the periphery of the SRS components. Follow the instructions on the notices.
After work on the SRS is completed, perform the SRS warning light check.
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 protection device which has a supplemental role to the seat belts.
When the ignition SW on, the current from the IGN fuse flows to TERMINAL (B) 5 of the center airbag sensor assembly.
If an accident occurs while driving, deceleration caused by a frontal impact is detected (by sensor) and when the frontal
impact exceeds a set level, the current from the IGN fuse flows to TERMINAL (B) 5 of the center airbag sensor assembly.
This current flows to TERMINAL (B) 14, (A) 2, (C) 5 to TERMINAL 1 of the airbag squib (Steering wheel pad) and
Pretensioners to TERMINAL 2 to TERMINAL (B) 13, (A) 1, (C) 6 of the center airbag sensor assembly, and also flows to
TERMINAL (B) 11 of the center airbag sensor assembly to TERMINAL (A) 4 of the passenger airbag manual On–Off SW to
TERMINAL (A) 2 to TERMINAL 1 of the airbag squib (Front passenger airbag assembly) to TERMINAL 2 to TERMINAL (A)
3 of the passenger airbag manual On–Off SW to TERMINAL (A) 1 to TERMINAL (B) 10 of the center airbag sensor
assembly. Furthermore, the current flows to TERMINAL (B) 27 or (B) 28 to GROUND, causing the center airbag squibs to
expand.
When the safing sensor built into the center airbag sensor assembly is on, airbag sensor is off and the current from the IGN
fuse flows same as above–mentioned flowing, causing the airbag squibs to expand. When the safing sensor built into the
center airbag sensor assembly is on, the airbag sensor on one of the above-mentioned circuits is activated so that current
flows to the airbag squibs and causes them 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
passenger.
1. FRONT PASSENGER AIRBAG ON/OFF OPERATION
When the passenger airbag manual On–Off SW is on, the current flowing from the IGN fuse to the airbag squib (Front
passenger airbag assembly) is same as above, causing the airbag squib (Front passenger airbag assembly) to expand in an
accident.
If the passenger airbag manual On–Off SW is turned to off, the current flows from the ACC fuse to TERMINAL (B) 13 of the
passenger airbag OFF indicator (Integration control and panel) to TERMINAL (A) 3 to TERMINAL (B) 2 of the airbag manual
On–Off SW to TERMINAL (B) 1 to TERMINAL (A) 1 of the integration control and panel to TERMINAL (B) 1 to GROUND,
lighting the indicator up. Then the current between TERMINAL (B) 11 of the airbag sensor assembly and the airbag squib
(Front passenger airbag assembly) is cut off, so that it does not expand the airbag squib (Front passenger airbag assembly)
in an accident.

SYSTEM OUTLINE
In the conventional system, the 2–4 select SW and the transfer shift lever was used to shift the mode between H–L. In this
system, the transfer shift lever is not used, and the H–L mode shift can be done by the transfer shift actuator.
The mode can be changed by the touch select 2–4 SW and touch select high–low in the integration control and panel.
The shift range is controlled according to the vehicle speed sensor and Park/Neutral position SW, and the indicator light is
turned ON to inform the driver if any of the following conditions are detected:
∗ The shift is not completed even though 3 seconds have elapsed after transfer operation.
∗ The vehicle speed is above approximately 100 km/h (63 mph) when shifting from H2 to H4.
∗ The vehicle speed is below approximately 5 km/h (3 mph) or the A/T shift lever is in a position other than N position, when
shifting from H4 to L4 or visa versa, and from L4 to H2.
TRANSFER OPERATION
H2 to H4
When the touch select 2–4 SW in the integration control and panel is turned ON, a signal is input into TERMINAL 4 of the
4WD control ECU.
The 4WD control ECU is activated by this, and the current flows from the 4WD control ECU TERMINAL 13 to transfer shift
actuator TERMINAL 1 to motor to TERMINAL 2 to 4WD control ECU TERMINAL 26 to GROUND, and the transfer shifts to
4WD (H4 position.)
When the system shifts to 4WD, the detection SW (Transfer 4WD position) is turned ON, and the current flows from 4WD
control ECU TERMINAL 11 to ADD actuator TERMINAL 5 to motor to TERMINAL 1 to 4WD control ECU TERMINAL 24 to
GROUND, and the ADD actuator is activated, and the ADD is connected. When the ADD is connected, the detection SW
(ADD position SW) is turned ON, and the 4HI Indicator light comes ON.
H4 to H2
When the touch select 2–4 SW in the integration control and panel is turned OFF, a signal is input into TERMINAL 4 of the
4WD control ECU.
2WD (H2 position.)
When the system shifts to 2WD, the detection SW (Transfer 4WD position) is turned OFF, and the current flows from 4WD
GROUND, and the ADD actuator is activated, and the ADD is disconnected. When the ADD is disconnected, the detection
SW (ADD position SW) is turned OFF, and the 4HI indicator Light turns OFF.
H4 to L4
When the touch select high–low SW in the integration control and panel is turned ON, a signal is input into TERMINAL 7 of
the 4WD control ECU.
4WD LO position (L4 position.)
The 4HI Indicator is turned OFF and the 4LO indicator is turned ON.
L4 to H4
When the touch select high–low SW in the integration control and panel is turned OFF, a signal is input into TERMINAL 7 of
the 4WD control ECU.
4WD HI position (H4 Position.)
The 4HI indicator is turned ON and the 4LO indicator is turned OFF.
The shift is not completed even though 3 seconds have elapsed after transfer operation.
∗ The vehicle speed is above approximately 100 km/h (63 mph) when shifting from H2 to H4.
∗ The vehicle speed is below approximately 5 km/h (3 mph) or the A/T Shift Lever is in a position other than N position,
when shifting from H4 to L4 or visa versa, and from L4 to H2.
L4 to H2
When the touch select 2–4 SW in the integration control and panel is turned OFF, a signal is input into TERMINAL 4 of the
4WD control ECU.
actuator TERMINAL 2 to motor to TERMINAL 1 to 4WD control ECU TERMINAL 13 to GROUND, and the detection SW
(Transfer L4 position) is turned OFF.
Furthermore, the motor rotates to shift the transfer to 2WD (H2 position.)
When the system shifts to 2WD, the detection SW (Transfer 4WD position) is turned OFF, and the current flows from 4WD
GROUND, and the ADD actuator is activated, and the ADD is disconnected. When the ADD is disconnected, the detection
SW (ADD position SW) is turned OFF, and the 4LO indicator light turns OFF.
177
4WD (2UZ–FE)
H2 to L4
When the touch select 2–4 SW in the integration control and panel is turned ON, and the touch select high–low SW is turned
ON, a signal is input into TERMINAL 4 of the 4WD control ECU.
4WD (H4 position.)
When the system shifts to 4WD, the detection SW (Transfer 4WD position) is turned ON, and the current flows from 4WD
GROUND, and the ADD actuator is activated, and the ADD is connected. Then a signal is input into TERMINAL 7 of the
4WD control ECU and the 4WD control ECU is activated by this, so the current flows from the 4WD control ECU TERMINAL
13 to transfer shift actuator TERMINAL 1 to motor to TERMINAL 2 to 4WD control ECU TERMINAL 26 to GROUND. The
transfer shifts to 4WD LO position (L4 position), and the 4LO indicator light comes ON.

SYSTEM OUTLINE
Current always flows to TERMINAL 3 of the integration relay through the POWER fuse.
1. MANUAL LOCK OPERATION
To push the door lock control SW or door key lock and unlock SW to LOCK position, a lock signal is input to the integration
relay and causes the relay to function. Current flows from TERMINAL 3 of the relay to TERMINAL 13 to TERMINAL 2 of the
door lock motors to TERMINAL 3 to TERMINAL 12 of the relay to TERMINAL 8 to GROUND and the door lock motor causes
the door to lock.
2. MANUAL UNLOCK OPERATION
To push the door lock control SW or door key lock and unlock SW to UNLOCK position, an unlock signal is input to the
integration relay and causes the relay to function. Current flows from TERMINAL 3 of the relay to TERMINAL 12 to
TERMINAL 3 of the door lock motors to TERMINAL 2 to TERMINAL 13 of the relay to TERMINAL 8 to GROUND and the
door lock motor causes the door to unlock.
3. DOUBLE OPERATION UNLOCK OPERATION
When the door key lock and unlock SW LH is turned to unlock position, only the front LH door is mechanically unlocked.
Turning the door key lock and unlock SW LH to the unlock side causes a signal to be input to the relay, and if the signal is
input again within 3 seconds by turning the door key lock and unlock SW LH to the unlock side again, current flows from
TERMINAL 12 of the integration relay to TERMINAL 3 of the door lock motors, TERMINAL 2 to TERMINAL 13 of the
integration relay to TERMINAL 8 to GROUND, causing the door lock motors to operate and unlock the doors.
4. KEY CONFINE PREVENTION FUNCTION
∗ Operating door lock knob (In door lock motor operation)
With ignition key in cylinder (Unlock warning SW on), when any 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 integration relay. As a result,
current flows from TERMINAL 3 of the relay to TERMINAL 12 to TERMINAL 3 of the door lock motors to TERMINAL 2 to
TERMINAL 13 of the relay to TERMINAL 8 to GROUND and causes all the doors to unlock.
∗ Operating door lock control SW or door key lock and unlock SW
With ignition key in cylinder (Unlock warning SW on), when any door is opened and locked using the door lock control
SW or door key lock and unlock SW, all doors are locked once but each door is unlocked by the function of the SW
contained in motor, which inputs the signal to the integration relay. According to this input signal, current flows from
TERMINAL 3 of the relay to TERMINAL 12 to TERMINAL 3 of the door lock motors to TERMINAL 2 to TERMINAL 13 of
the relay to TERMINAL 8 to GROUND and causes all the doors to unlock.

SYSTEM OUTLINE
Current always flows to TERMINAL 3 of the integration relay through the POWER fuse.
1. MANUAL LOCK OPERATION
To push the door lock control SW or door key lock and unlock SW to LOCK position, a lock signal is input to the integration
relay and causes the relay to function. Current flows from TERMINAL 3 of the relay to TERMINAL 13 to TERMINAL 2 of the
door lock motors to TERMINAL 3 to TERMINAL 12 of the relay to TERMINAL 8 to GROUND and the door lock motor causes
the door to lock.
2. MANUAL UNLOCK OPERATION
To push the door lock control SW or door key lock and unlock SW to UNLOCK position, an unlock signal is input to the
integration relay and causes the relay to function. Current flows from TERMINAL 3 of the relay to TERMINAL 12 to
TERMINAL 3 of the door lock motors to TERMINAL 2 to TERMINAL 13 of the relay to TERMINAL 8 to GROUND and the
door lock motor causes the door to unlock.
3. DOUBLE OPERATION UNLOCK OPERATION
When the door key lock and unlock SW LH is turned to unlock position, only the front LH door is mechanically unlocked.
Turning the door key lock and unlock SW LH to the unlock side causes a signal to be input to the relay, and if the signal is
input again within 3 seconds by turning the door key lock and unlock SW LH to the unlock side again, current flows from
TERMINAL 12 of the integration relay to TERMINAL 3 of the door lock motors, TERMINAL 2 to TERMINAL 13 of the
integration relay to TERMINAL 8 to GROUND, causing the door lock motors to operate and unlock the doors.
4. KEY CONFINE PREVENTION FUNCTION
∗ Operating door lock knob (In door lock motor operation)
With ignition key in cylinder (Unlock warning SW on), when any 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 integration relay. As a result,
current flows from TERMINAL 3 of the relay to TERMINAL 12 to TERMINAL 3 of the door lock motors to TERMINAL 2 to
TERMINAL 13 of the relay to TERMINAL 8 to GROUND and causes all the doors to unlock.
∗ Operating door lock control SW or door key lock and unlock SW
With ignition key in cylinder (Unlock warning SW on), when any door is opened and locked using the door lock control
SW or door key lock and unlock SW, all doors are locked once but each door is unlocked by the function of the SW
contained in motor, which inputs the signal to the integration relay. According to this input signal, current flows from
TERMINAL 3 of the relay to TERMINAL 12 to TERMINAL 3 of the door lock motors to TERMINAL 2 to TERMINAL 13 of
the relay to TERMINAL 8 to GROUND and causes all the doors to unlock.

POWER WINDOW
SYSTEM OUTLINE
With the ignition SW turned on, current flows through the ECU IG fuse to TERMINAL 9 of the integration relay to TERMINAL
2 to TERMINAL 1 of the power relay to TERMINAL 2 to GROUND, activating the power relay, and the current flowing from
TERMINAL 5 of the power relay flows to TERMINAL 3 to TERMINAL 9 of the power window master SW and TERMINAL 4 of
the power window control SW RH.
1. MANUAL OPERATION (DRIVER’S WINDOW)
With the ignition SW turned on and with the power window master SW (Manual SW) in UP position, the current flowing to
TERMINAL 9 of the power window master SW flows to TERMINAL 3 to TERMINAL 2 of the power window motor LH to
TERMINAL 1 to TERMINAL 4 of the master SW to TERMINAL 1 to GROUND and causes the power window motor to rotate
in the up direction. The window ascends only while the SW is being pushed.
In down operation, the current flowing from TERMINAL 9 of the power window master SW to TERMINAL 4 flows to
TERMINAL 1 of the motor LH to TERMINAL 2 to TERMINAL 3 of the master SW to TERMINAL 1 to GROUND, flowing in the
opposite direction to manual up operation, causing the motor to rotate in reverse and lowering the window.
2. AUTO DOWN OPERATION (DRIVER’S WINDOW)
With the ignition SW on and with the auto SW of the power window master SW in DOWN position, the current flowing to
TERMINAL 9 of the master SW flows to TERMINAL 4 of the master SW to TERMINAL 1 of the power window motor LH to
TERMINAL 2 to TERMINAL 3 of the master SW to TERMINAL 1 to GROUND, causing the motor to rotate towards the down
side.
Then the solenoid in the master SW is activated and it locks the auto SW being pushed, causing the motor to continue to
rotate in auto down operation.
When the window has completely descended, the current flowing between TERMINAL 3 of the master SW and TERMINAL 1
increases. As a result, the solenoid stops operating, the auto SW turns off and the flowing from TERMINAL 9 of the master
SW to TERMINAL 4 is cut off, stopping the motor so that auto stop occurs.
3. STOPPING OF AUTO DOWN AT DRIVER’S WINDOW
When the manual SW (Driver’s) is pushed to the up side during auto down operation, a ground circuit opens in the master
SW and current does not flow from TERMINAL 3 of the master SW to TERMINAL 1, so the motor stops, causing auto down
operation to stop. If the manual SW is pushed continuously, the motor rotates in the up direction in manual up operation.
4. MANUAL OPERATION BY POWER WINDOW CONTROL SW (PASSENGER’S WINDOW)
With the power window control SW RH is pushed to the up side, the current flowing from TERMINAL 4 of the power window
control SW RH flows to TERMINAL 3 of the power window control SW RH to TERMINAL 1 of the power window motor RH to
TERMINAL 2 to TERMINAL 1 of the power window control SW RH to TERMINAL 2 to TERMINAL 10 of the master SW to
TERMINAL 1 to GROUND. This causes the power window motor RH to rotate in the up direction. Up operation is continuous
only while the power window control SW RH is pushed to the up side. When the window descends, the current flowing to the
motor flows in the opposite direction, from TERMINAL 1 to TERMINAL 2, and the motor rotates in revers.
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 tried, the current from TERMINAL 9 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. KEY OFF POWER WINDOW OPERATION
With the ignition SW turned from on to off, the integration relay operates for about 43 seconds and current flows from
TERMINAL 1 of the power relay to TERMINAL 2 to GROUND. For this period, current also flows TERMINAL 5 to TERMINAL
3. This current flows to TERMINAL 9 of the power window master SW and to TERMINAL 4 of the power window control SW
RH. As a result, for about 43 seconds after the ignition SW is turned off, it is possible to raise and lower the power window by
the functioning of the integration relay. Also, by opening the door (Door courtesy SW on) within about 43 seconds after
turning the ignition SW to off, a signal is input to TERMINAL 3, 14 or 15 of the integration relay. As a result, the integration
relay turns off, and up and down movement of the window stops.

SYSTEM OUTLINE
Current always flows to TERMINAL (B) 5 of the combination meter through the DOME fuse.
1. SEAT BELT WARNING SYSTEM
When the ignition SW is turned on, current flows from the GAUGE fuse to TERMINAL (A) 9 of the combination meter. This
current activates the combination meter and the current flowing through the seat belt warning light flows from TERMINAL (B)
8 to GROUND, causing the warning light to light up. A buckle SW off signal is input to TERMINAL (B) 12 of the combination
meter to TERMINAL (B) 8 to GROUND, causing the warning light to light up. A buckle SW off signal is input to TERMINAL
(B) 12 of the combination meter, the current flowing to TERMINAL (B) 5 of the combination meter flows from TERMINAL (B)
8 to GROUND and the seat belt warning buzzer sounds. However, if the seat belt is put on during this period (While the
buzzer is sounding), signal input to TERMINAL (B) 12 of the combination meter stops and the current flow from TERMINAL
(B) 5 of the combination meter to TERMINAL (B) 8 to GROUND is cut, causing the buzzer to stop.
2. KEY REMINDER SYSTEM
With the ignition key inserted in the key cylinder (Unlock warning SW on), the ignition SW still off and driver’s door open
(Door courtesy SW on), when a signal is input to TERMINAL (B) 13 of the combination meter, the combination meter
operates, current flows from TERMINAL (B) 5 of the combination meter to TERMINAL (B) 8 to GROUND and key reminder
buzzer sounds.

With the ignition SW turned on, current flows to TERMINAL 17 of the wiper and washer SW, TERMINAL 3 of the washer
motor and TERMINAL 2 of the wiper motor through the WIP fuse.
1. LOW SPEED POSITION
With wiper SW turned to LOW position, current flows from TERMINAL 17 of the wiper and washer SW to TERMINAL 7 to
TERMINAL 5 of the wiper motor to TERMINAL 4 to GROUND and causes the wiper motor to run at low speed.
2. HIGH SPEED POSITION
With wiper SW turned to HIGH position, current flows from TERMINAL 17 of the wiper and washer SW to TERMINAL 8 to
TERMINAL 3 of the wiper motor to TERMINAL 4 to GROUND and causes the motor to run at high speed.
3. INT POSITION
With wiper SW turned to INT position, the relay operates and the current which is connected by relay function flows from
TERMINAL 17 of the wiper and washer SW to TERMINAL 2 to GROUND. This flowing the intermittent circuit and current
flows from TERMINAL 17 of the wiper and washer SW to TERMINAL 7 to TERMINAL 5 of the wiper motor to TERMINAL 4 to
GROUND and the wiper functions.
The intermittent operation is controlled by charging and discharging of the condenser installed in the relay and the
intermittent time is controlled by a time control SW to change the charging time of the condenser.
4. WASHER INTERLOCKING OPERATION
With the washer SW turned to on, current flows from TERMINAL 3 of the washer motor to TERMINAL 4 to TERMINAL 11 of
the wiper and washer SW to TERMINAL 2 to GROUND and causes to the washer motor to run, and the window washer is
jetted.
This causes current to flow to washer continuous operation circuit in TERMINAL 17 of the wiper and washer SW to
TERMINAL 7 to TERMINAL 5 of the wiper motor to TERMINAL 4 to GROUND and the wiper functions.

SYSTEM OUTLINE
1. HEATER BLOWER MOTOR OPERATION
Current is applied at all times through the HTR fuse to TERMINAL 5 of the HTR relay.
When the ignition SW is turned on, current flows through the GAUGE fuse to TERMINAL 2 of the HTR relay to the coil side
to TERMINAL 1 to TERMINAL 3 of the blower SW.
∗ Low speed operation

When the blower SW is moved to LO position, current flows to TERMINAL 3 of the blower SW to TERMINAL 1 to
GROUND, causing the HTR relay to switch on. This causes the current to flow from the HTR fuse to TERMINAL 5 of the
HTR relay to TERMINAL 3 to TERMINAL 1 of the blower motor to TERMINAL 2 to TERMINAL 4 of the blower resistor to
TERMINAL 1 to GROUND, causing the blower motor to rotate at low speed.
∗ Medium speed operation (Operation at M1, M2)

When the blower SW is moved to M1 position, current flows to TERMINAL 3 of the blower SW to TERMINAL 1 to
GROUND, turning the HTR relay to switch on. This causes the current to flow from the HTR fuse to TERMINAL 5 of the
HTR relay to TERMINAL 3 to TERMINAL 1 of the blower motor to TERMINAL 2 to TERMINAL 4 of the blower resistor to
TERMINAL 3 to TERMINAL 4 of the blower SW to TERMINAL 1 to GROUND. At this time, the blower resistance of the
blower resistor is less than at low speed, so the blower motor rotates at medium low speed.
When the blower SW is moved to M2 position, current flows through the motor flows from TERMINAL 4 of the blower
resistor to TERMINAL 2 to TERMINAL 8 of the blower SW to TERMINAL 1 to GROUND. At this time, resistance of the
blower resistor is less than at M1 position, so the blower motor rotates at medium high speed.
∗ High speed operation

When the blower SW is moved to HIGH position, current flows to TERMINAL 3 of the blower SW to TERMINAL 1 to
GROUND, turning the HTR relay to switch on.
This causes the current to flow from the HTR fuse to TERMINAL 5 of the HTR relay to TERMINAL 3 to TERMINAL 1 of the
blower motor to TERMINAL 2 to TERMINAL 5 of the blower SW to TERMINAL 1 to GROUND, causing the blower motor to
rotate at high speed.
2. OPERATION OF AIR INLET CONTROL SERVO MOTOR
∗ Switching from FRESH to RECIRC
With the ignition SW turned on, current flows from the GAUGE fuse to TERMINAL 5 of the air inlet control servo motor.
When the RECIRC/FRESH SW is switched to the RECIRC side, current flows from TERMINAL 5 of the air inlet control
servo motor to TERMINAL 1 to TERMINAL (A) 13 of the integration control and panel to TERMINAL (B) 1 to GROUND.
The motor rotates and the damper moves to the RECIRC side. When it is in the RECIRC position, current is cut inside the
servo motor and the damper stops at that position.
∗ Switching from RECIRC to FRESH

With the ignition SW turned on, when the RECIRC/FRESH SW is switched to the FRESH side, current flows from
TERMINAL 5 of the air inlet control servo motor to TERMINAL 2 to TERMINAL (A) 15 of the integration control and panel
to TERMINAL (B) 1 to GROUND, the motor rotates and the damper moves to the FRESH side. when it is in the FRESH
position, current is cut inside the servo motor and the damper stops at that position. When the ignition SW turned on, and
mode SW (Integration control and panel) is at DEF or F/DEF position, it causes the damper to move to the FRESH side.
Whether the RECIRC/FRESH SW (Integration control and panel) is on or not.
3. AIR CONDITIONING OPERATION
When the blower SW is on, current flows from the GAUGE fuse to the HEATER relay (Coil side) to TERMINAL 3 of the
blower SW to TERMINAL 1 to GROUND, activating the HTR relay. This causes current to flow from the HTR fuse to the HTR
relay (Point side) to A/C fuse to TERMINAL (B) 12 of the A/C SW (Integration control and panel). When the A/C SW
(Integration Control and panel) is turned on. Current flows from the A/C fuse to TERMINAL (B) 12 of the integration control
and panel to TERMINAL (A) 8 to A/C magnetic clutch. Causing The compressor to operate.
When blower SW is on and mode SW (Integration control and panel) is at DEF or F/DEF position, it causes A/C to run
whether A/C SW (Integration control and panel) is on or not.
