NOTE:
Graphics in this test show the Front Passenger Latch. The 2 rear passenger latches (if applicable) are similar. See the schematic for the connector cavity numbers.
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. Turn the ignition on.
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 the BODY VERIFICATION TEST. Refer to STANDARD PROCEDURE .
  No
  - Go To 2.

1. Turn the ignition off.
2. Disconnect the TIPM C5 connector.
3. 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?
  
  Yes
  - Go To 3.
  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 the BODY VERIFICATION TEST. Refer to STANDARD PROCEDURE .
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 1, 000 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 the BODY VERIFICATION TEST. Refer to STANDARD PROCEDURE .
  No
  - Go To 4.

1. Measure the resistance of the appropriate Door Lock Driver circuit between the TIPM C5 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 the BODY VERIFICATION TEST. Refer to STANDARD PROCEDURE .

1. Measure the resistance between Ground and the appropriate Door Lock Driver circuit.
  Is the resistance below 1, 000 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 the BODY VERIFICATION TEST. Refer to STANDARD PROCEDURE .
  No
  - Replace the Totally Integrated Power Module in accordance with the Service Information.
  - Perform the BODY VERIFICATION TEST. Refer to STANDARD PROCEDURE .
