For a complete wiring diagram, refer to the Wiring Information. Electrical Diagrams






1. DRIVER DOOR LATCH INOPERATIVE




1. Disconnect the Driver Door Latch connector.
2. Connect a test light between the (P393) Door Lock Driver circuit and the (P1) Driver Door Unlock Driver circuit.
3. Close the front doors or trip the door latches to the closed position.
4. Operate the door locks in both positions and observe the test light.

Does the test light illuminate brightly for approximately 300 ms. when the door locks are actuated?

Yes

- Replace the Driver Door Latch.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

No

- Go To 2

2. CHECK (P1) DRIVER DOOR UNLOCK DRIVER CIRCUIT FOR AN OPEN




1. Disconnect the Cluster C1 connector.
2. Measure the resistance of the (P1) Driver Door Unlock Driver circuit between the Latch connector and the Cluster C1 connector.

Is the resistance below 2.0 ohms?

No

- Repair the (P1) Driver Door Unlock Driver circuit for an open.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

Yes

- Go To 3

3. CHECK (P1) DRIVER DOOR UNLOCK DRIVER CIRCUIT FOR A SHORT TO GROUND




1. Measure the resistance between Ground and the (P1) Driver Door Unlock Driver circuit.

Is the resistance below 1,000 ohms?

Yes

- Repair the (P1) Driver Door Unlock Driver circuit for a short to ground.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

No

- Go To 4

4. CHECK (P393) DOOR LOCK DRIVER CIRCUIT FOR AN OPEN




1. Measure the resistance of the (P393) Door Lock Driver circuit between the Cluster C1 connector and the Driver Door Latch connector.

Is the resistance below 2.0 ohms?

Yes

- Go To 5

No

- Repair the (P393) Door Lock Driver circuit for an open.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

5. CHECK (P393) DOOR LOCK DRIVER CIRCUIT FOR A SHORT TO GROUND




1. Measure the resistance between Ground and the (P393) Door Lock Driver circuit.

Is the resistance below 1,000 ohms?

Yes

- Repair the (P393) Door Lock Driver circuit for a short to ground.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

No

- Replace the Instrument Cluster.
- Perform the BODY VERIFICATION TEST. Body Verification Test.
