SWING GATE LOCK INOPERATIVE





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






1. SWING GATE LATCH INOPERATIVE




1. Disconnect the Swing Gate Latch connector.
2. Connect a test light between the (P304) Swing Gate Lock Driver circuit and the (P406) Swing Gate Unlock Driver circuit.
3. Close the front doors or trip the front 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 Swing Gate Latch.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

No

- Go To 2

2. (P306) SWING GATE UNLOCK DRIVER CIRCUIT OPEN




1. Turn the ignition off.
2. Disconnect the TIPM C5 connector.
3. Measure the resistance of the (P306) Swing Gate Unlock Driver circuit between the Latch connector and the TIPM C5 connector.

Is the resistance below 2.0 ohms?

No

- Repair the (P306) Swing Gate Unlock Driver circuit for an open.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

Yes

- Go To 3

3. (P306) SWING GATE UNLOCK DRIVER CIRCUIT SHORT TO GROUND




1. Measure the resistance between Ground and the (P306) Swing Gate Unlock Driver circuit.

Is the resistance below 1,000 ohms?

Yes

- Repair the (P306) Swing Gate Unlock Driver circuit for a short to ground.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

No

- Go To 4

4. (P304) SWING GATE LOCK DRIVER CIRCUIT OPEN




1. Disconnect the TIPM C6 connector.
2. Measure the resistance of the (P304) Swing Gate Lock Driver circuit between the TIPM C6 connector and the Swing Gate Latch connector.

Is the resistance below 2.0 ohms?

Yes

- Go To 5

No

- Repair the (P304) Swing Gate Lock Driver circuit for an open.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

5. (P304) SWING GATE DOOR LOCK DRIVER CIRCUIT SHORT TO GROUND




1. Measure the resistance between Ground and the (P304) Swing Gate Lock Driver circuit.

Is the resistance below 1,000 ohms?

Yes

- Repair the (P304) Swing Gate Lock Driver circuit for a short to ground.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

No

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