When the ignition SW is turned to ACC position the current from the ACC fuse flows to TERMINAL 1 of the shift lock ECU, in
the ON position, the current from the ECU±IG fuse flows to TERMINAL 3 of the ECU.
1. SHIFT LOCK MECHANISM
With the ignition SW on, 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 (Continuity between P1 and P of the shift lock control SW) is input to the ECU, the ECU operates and
current flows from TERMINAL 3 of the ECU to TERMINAL SLS+ of the shift lock solenoid to solenoid to TERMINAL SLS± to
TERMINAL 5 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 the P.
2. KEY INTERLOCK MECHANISM
With the ignition SW ON or ACC position, when the shift lever is put in P position (No continuity between P2 and P of shift
lock control SW), the current flowing from TERMINAL 4 of the ECU to the 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.

WIRELESS DOOR LOCK CONTROL
The current is always sent from DOOR fuse to TERMINAL B of body ECU. At the same time, the current is always sent from
DOME fuse to TERMINAL CPUB of power window master SW, and from ECU±B fuse to wireless door lock receiver. When
ignition SW is turned on, the current is sent from GAUGE fuse to TERMINAL IG of body ECU.
1. WIRELESS DOOR LOCK OR UNLOCK NORMAL OPERATION
*Lock operation
When the LOCK SW of the transmitter is pushed, all the doors are locked.
*Unlock operation
When the UNLOCK SW of the transmitter is pushed, all the doors are unlocked.
2. AUTOMATIC LOCK OPERATION
After all the doors are unlocked by pushing the UNLOCK SW of the transmitter, unless each of the doors is opened or the
ignition key is inserted, all the doors are locked again.
3. VISUAL CONFIRMATION OF LOCK OR UNLOCK FUNCTION
When doors are locked by using the transmitter, the taillight and parking lights blink once. When doors are unlocked by using
the transmitter, the taillights and parking lights blink twice. If UNLOCK SW of the transmitter is pushed while all the doors are
locked, doors are unlocked and the room lights are turned on simultaneously.
4. WIRELESS CONTROL STOP FUNCTION
If the following situations occur, wireless door lock function does not operate.
*When each of the doors opens. (Door courtesy SW is on)
*When ignition key is inserted to ignition SW. (Unlock warning SW is on)
*When ignition SW is on.
5. REPEAT FUNCTION
If the doors are not locked after the lock signal is out put from transmitter by pushing LOCK SW, the lock signal is sent again
to lock the doors.
6. PANIC MODE FUNCTION
When the panic SW of the transmitter is pushed, the horn comes on, and the headlight and taillight flashes.

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 ºLOCKº 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, side airbag assembly, seat belt pretensioner,
airbag sensor assembly or side airbag sensor 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, side airbag assembly, seat belt pretensioner, airbag sensor assembly and side 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, side airbag assembly, seat belt
pretensioner, airbag sensor assembly or side airbag sensor assembly in order to reuse it.

If the steering wheel pad, front passenger airbag assembly, side airbag assembly, seat belt pretensioner, airbag sensor
assembly or side 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 kW/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.
