Fuse Inspection:

Action Chart:

Step 1
Check the DOOR LOCK 30A fuse and ROOM 15A fuse in the fuse block.

Step 2
1. Remove the passenger's front side trim.

Voltmeter Connection:

Action Chart:

2. Measure the voltage at the (W/G) terminal wire of the door lock timer unit connector.

Ohmmeter Connection:

Action Chart:

Step 3
1. Disconnect the door lock timer unit connector.
2. Check for continuity between the (B) terminal wire and ground.

Step 4

Voltmeter Connection:

Reference:

1. Measure the voltage between the (G/B) terminal wire and ground with the driver's door lock knob in the following positions.
2. If correct, go to Step 5.
3. If not as specified, go to Step 8.

Ohmmeter Connection:

Action Chart:

Step 5
1. Disconnect the negative battery cable.
2. Check for continuity between the (G/B) terminal wire and ground with the driver's door lock knob in the unlock position.

Step 6

Voltmeter Connection:

Reference:

1. Measure the voltage at the terminal wires of the door lock timer unit connector with the driver's door lock in the following positions.
2. If correct, go to Step 7.
3. If not as specified, check the door lock timer unit

Step 7
1. Remove the passenger's/rear door trim and door screens.

Voltmeter Connection:

Reference:

2. Measure the voltage at the terminal wires of the door lock actuator connectors with the driver's door lock knob in the following positions.
3. If correct, check the door lock actuators.
4. If not as specified, repair the wiring harness (door lock timer unit-door lock actuator).

Step 8
1. Remove the driver's door trim arid door screen.

Voltmeter Connection:

Reference:

2. Measure the voltage at the (G/B) terminal wire of the door lock-link switch connector with the driver's door lock knob in the following positions.
3. If correct, repair the wiring harness (door lock timer unit-door lock link switch).
4. If not as specified, go to Step 9.

Step 9

Voltmeter Connection:

Action Chart:

Measure the voltage at the (L/R) terminal wire of the door lock-link switch connector.

Ohmmeter Connection:

Action Chart:

Step 10
1. Disconnect the door lock-link switch connector.
2. Check for continuity between the (B) terminal wire and ground.
