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 MET
fuse. When the light control SW is turned to TAIL or HEAD position, current is applied to TERMINAL 8 of the combination
meter through the TAIL fuse.

1. 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 10 of the combination meter, and from the door courtesy SW
(Driver’s side) to TERMINAL 16 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.

2. Light Reminder System
When the light control SW is in TAIL or HEAD position, the ignition SW turned to OFF from ON position, ignition key is not in
the key cylinder 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,
the buzzer in the combination meter goes on to remind the light is lighting up.

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 line pressure, throttle pressure, lock–up pressure and accumulator pressure etc. through the solenoid valve. The
electronically controlled transmission is a system which precisely controls 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 for each 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. Lock–Up Operation
When the transmission control ECU decides based on each signal that the lock–up condition has been met, the current
flows through TERMINAL SL of the transmission control ECU to TERMINAL 7 of the ECT solenoid to GROUND, causing
lock–up operation.

2. Stop Lamp SW Circuit
If the brake pedal is depressed (Stop lamp SW on) when driving in lock–up condition, a signal is input to TERMINAL STP of
the transmission control ECU. The transmission control ECU operates and cuts the current to the solenoid to release
lock–up.

System Outline
This system controls the respective brake fluid pressures acting on the 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 skid control ECU with
actuator.
(2) Stop lamp SW signal
A signal is input to TERMINAL STP of the skid control ECU with actuator when the brake pedal is depressed.

2. System Operation
During sudden braking, the skid control ECU with actuator which has signals input from each sensor lets the hydraulic
pressure acting on each wheel cylinder escape to the reservoir.
The pump inside the skid control ECU with actuator 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 skid control ECU with actuator 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.

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.

System Outline

The SRS is a driver protection device which has a supplemental role to the seat belts.
When the ignition SW is turned to ON, the current from the ignition SW flows to TERMINAL 21 of the airbag sensor assembly
center.
If an accident occurs while driving, when the frontal impact exceeds a set level, the current from the ignition SW flows to
TERMINAL 5 of the airbag sensor assembly center to the airbag squibs TERMINAL 6 of the airbag sensor assembly center
to TERMINAL 25, 26 or BODY GROUND to GROUND, 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.

System Outline

Driving mode is switched to H2 or H4 or L4 when the driver operates the transfer shift lever. Transfer indicator SW (4WD
position) is turned on when the transfer shift lever is shifted in 4WD (H4 or L4).

1. 2-4 Select System

(1) Shifting from H4 to H2
When the transfer shift lever is changed from H4 to H2 position, transfer indicator SW (4WD position) detects OFF signal
to activate the ADD motor, which results in changing the transfer to 2WD (H2 position).
At this time, the transfer indicator SW (4WD position) are off.

(2) Shifting from H2 to H4
When the transfer shift lever is changed from H2 to H4 position, transfer indicator SW (4WD position) detects ON signal
to activate the ADD motor, which results in changing the transfer to 4WD (H4 position) to light up 4WD indicator.

(3) Shifting from H4 to L4
When the transfer shift lever is changed from H4 to L4 position, the shift fork shaft moves to change the transfer to 4WD
(L4 position), which results in turning ON transfer indicator SW (L4 position). ADD motor does not operate since it is only
the lever operation.

(4) Shifting from L4 to H4
When the transfer shift lever is changed from L4 to H4 position, the shift fork shaft moves. When transfer indicator SW
(L4 position) is turned OFF, the transfer changes to 4WD (H4 position). ADD motor does not operate since it is only the
lever operation.

2. Other Control
When abnormality is found in the 4WD system, the driver is warned by 4WD indicator light’s flashing.

System Outline

When the ignition SW is turned to ACC position the current from the ACC fuse flows to TERMINAL 6 of the shift lock control
ECU. When the ignition SW is turned to ON position, the current from the ECU–IG&GAUGE fuse flows to TERMINAL 1 of
the shift lock control ECU.

1. Shift Lock Mechanism
If the brake pedal is depressed with the ignition SW set at ON (The stop lamp SW is on), the shift lock control ECU is
activated, allowing the driver to change the shift lever to a position other than the P position.

2. Key Interlock Mechanism
With the ignition SW at ON or ACC position, when the shift lever is put in P position, the current flowing from TERMINAL 12
of the shift lock control ECU to key interlock solenoid is cut off. This causes the key interlock solenoid to turn off (Lock lever
disengages from LOCK position) and the ignition key can be turned from ACC to LOCK position.

System Outline

1. Manual Lock Operation
When the door lock control SW or driver’s side door key lock and unlock SW (When driver’s seat belt is unfastened) are
operated to LOCK position, a lock signal is input to TERMINAL 14 of the integration relay and causes the integration relay to
function. The current flows from TERMINAL 5 of the integration relay to TERMINAL 3 to the door lock motors to TERMINAL
2 of the integration relay to TERMINAL 1 to GROUND and the door lock motors locks the door.

2. Manual Unlock Operation
When the door lock control SW or driver’s side door key lock and unlock SW (When driver’s seat belt is unfastened) are
operated to UNLOCK position, an unlock signal is input to TERMINAL 11 of the integration relay and causes the integration
relay to function. The current flows from TERMINAL 5 of the integration relay to TERMINAL 2 to the door lock motors to
TERMINAL 3 of the integration relay to TERMINAL 1 to GROUND and the door lock motors unlocks the door.

3. Speed–Sensitive Automatic Door Lock
Under the precondition that one of the doors is opened with the ignition SW OFF, the theft warning ECU outputs lock signal
to the integration relay and the relay sends the lock signal to all the door lock motors when all the flowing conditions are
satisfied.
∗ All the door are shut.
∗ The unlock warning SW is ON besides the ignition SW is ON.
∗ The vehicle speed reaches about 25km/h.

4. Ignition SW Linked Automatic Door Unlock
Under the precondition that the unlock warning SW is ON as well as the ignition SW is ON after door locked by the
speed–sensitive automatic door lock, the theft warning ECU outputs unlock signal to the integration relay and the relay
sends the unlock signal to all the door lock motor when all the flowing conditions are satisfied.
∗ The unlock warning SW is ON.
∗ The ignition SW is OFF.

System Outline

Door lock control (Lock and unlock) and panic control (Theft 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. Normal Operation
∗ Lock operation

When the lock button on the transmitter is pressed, all the doors are locked.
∗ Unlock operation

When the unlock button on the transmitter is pressed, all the doors are locked.

2. Visual Confirmation of Lock or Unlock
If all doors indicate that they are locked after the lock command, security horn sound and hazard lights will sound and flash
once. If any door indicates that it is open after the unlock command, theft deterrent horn sound and hazard lights will sound
and flash twice.

3. Automatic Lock Operation
All the doors are automatically relocked unless any door is opened within 15 seconds after pushing the button (Transmitter)
to unlock all the doors under conditions that the ignition key is not inserted into the ignition key cylinder (Unlock warning SW
off), ignition SW is at OFF and all the doors are completely closed.

4. Illuminated Entry Function
When pushing the unlock button (Transmitter), it turns on the lights, such as the ignition key cylinder lamp for approx. 30
seconds. If the doors are locked with lock button (Transmitter) during this operation and ignition key is in the ignition key
cylinder (Unlock warning SW ON) to turn ON the ignition SW, lighting is cancelled and the lights immediately fade out.

5. Panic Alarm Operation
When the panic button on the transmitter is pushed, alarm sound and flash starts. The panic alarm operation is canceled
when one of the lock button, unlock button and panic alarm button is pressed.

6. Door Ajar Warning (By Pushing Wireless Lock Button)
Half–shut door is warned with security horn sound (For 1 second) by pushing the lock button (Transmitter) when one of the
doors is not completely shut.
