Power Locks: Testing and Inspection

[Central door locking system]

Vehicles without keyless entry system
1. Every door lock actuator does not operate.
- Check fusible link No. 4.
- Check multi-purpose fuses No. 19 and No. 6.
- Check the door lock switch.
- Check the door lock relay.

2. One of the door lock actuators fails to operate.
- Check the actuator which fails to operate.

Vehicles with keyless entry system
1. The indicator will not light when the transmitter switch of the transmitter is pushed.
- Check or replace the battery.
- Replace the transmitter.

2. Though the transmitter is transmitting waves (the indicator is lit) the system does not operate.
- Check the way the code is registered.*
- Check the keyless entry control unit terminal for voltage.
- Check to see if the coaxial and ground cables of the antenna are connected.

3. Only either of the door or the backdoor can lock or unlock.
- Check the door lock relay.
- Check the door lock control unit.
- Check the voltage of the keyless entry control unit terminal.

4. All the doors and the backdoor can be locked or unlocked by the transmitter, but the dome light does not flicker nor light. (The interlocking lighting of the dome light according to opening and closing of the doors, however, is normal.)
- Check the voltage of the keyless entry control unit terminal.
- Check the harness.

NOTE:
*: Carry it out when the transmitter or the keyless entry control unit has been replaced, or a defect in memory of the code has occurred.
