One Passenger Door Lock Inoperative

ONE PASSENGER DOOR LOCK INOPERATIVE





For a complete wiring diagram refer to the Wiring Information .






Diagnostic Test

1. PASSENGER DOOR LATCH INOPERATIVE

NOTE: Graphics in this test show Left Rear Latch. For the other 2 passenger door lock cavities, see the schematic.





1. Turn the ignition off.
2. Disconnect the inoperative Passenger Door latch connector.
3. Connect a test light between the Door Lock Driver circuit and the Door Unlock Driver circuit.
4. Close the front doors or trip the door latches to the closed position.
5. 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 Passenger Door Latch Assembly.
- Perform BODY VERIFICATION TEST - VER 1.Body Verification Test

No

- Go To 2

2. PASSENGER DOOR UNLOCK DRIVER CIRCUIT OPEN




1. Disconnect the TIPM C5 connector.
2. Measure the resistance of the appropriate Door Unlock Driver circuit between the Latch connector and the TIPM C5 connector.

Is the resistance below 2.0 ohms?

No

- Using the wiring diagram/schematic as a guide, measure the circuit from the in-line door harness connector to the latch connector to determine if the wire is open in the door harness or the instrument panel harness. Repair the appropriate Door Unlock Driver circuit for an open.
- Perform BODY VERIFICATION TEST - VER 1.Body Verification Test

Yes

- Go To 3

3. PASSENGER DOOR UNLOCK DRIVER CIRCUIT SHORT TO GROUND




1. Measure the resistance between Ground and the appropriate Door Unlock Driver circuit.

Is the resistance below 1000.0 ohms?

Yes

- Using the wiring diagram/schematic as a guide, measure the circuit from the in-line door harness connector to ground to determine if the wire is shorted in the door harness or the instrument panel harness. Repair the appropriate Door Unlock Driver circuit for a short to ground.
- Perform BODY VERIFICATION TEST - VER 1.Body Verification Test

No

- Go To 4

4. PASSENGER DOOR LOCK DRIVER CIRCUIT OPEN




1. Disconnect the TIPM C6 connector.
2. Measure the resistance of the appropriate Door Lock Driver circuit between the TIPM C6 connector and the appropriate Door Latch connector.

Is the resistance below 2.0 ohms?

Yes

- Go To 5

No

- Using the wiring diagram/schematic as a guide, measure the circuit from the in-line door harness connector to the latch connector to determine if the wire is open in the door harness or the instrument panel harness. Repair the appropriate Door Lock Driver circuit for an open.
- Perform BODY VERIFICATION TEST - VER 1.Body Verification Test

5. PASSENGER DOOR LOCK DRIVER CIRCUIT SHORT TO GROUND




1. Measure the resistance between Ground and the appropriate Door Lock Driver circuit.

Is the resistance below 1000.0 ohms?

Yes

- Using the wiring diagram/schematic as a guide, measure the circuit from the in-line door harness connector to ground to determine if the wire is shorted in the door harness or the instrument panel harness. Repair the appropriate Door Lock Driver circuit for a short to ground.
- Perform BODY VERIFICATION TEST - VER 1.Body Verification Test

No

- Replace the Totally Integrated Power Module.
- Perform BODY VERIFICATION TEST - VER 1.Body Verification Test
