All Door Lock Output Circuit Shorted To Ground

*ALL DOOR LOCK OUTPUT CIRCUIT SHORTED TO GROUND





For a complete wiring diagram Consult Diagrams/Electrical.





NOTE: If any of the above circuits are shorted, the fuse may blow after one attempt to operate the locks.

Theory of Operation

The Door Lock Driver Right Doors circuit and the Door Lock Driver Left Doors circuits are connected together inside the module. Therefore any circuit that is connected to either one cause this problem.

Diagnostic Test

1. CHECK FOR TROUBLE CODES.
Turn the ignition on.
With the scan tool, read DTC's.
Does the scan tool display any Body related DTC's?

No

- Go To 2

Yes

- Diagnose and repair the DTC(s).

2. CHECK (P392) DOOR LOCK DRIVER RIGHT DOORS FOR SHORT TO GROUND




Turn the ignition off.
Disconnect the Cluster C1 connector.
Measure the resistance between ground and the (P392) Door Lock Driver Right Doors circuit.
Is the resistance below 1000.0 ohms?

No

- Go To 3

Yes

- Repair the (P392) Door Lock Driver Right Doors circuit for a short to ground.
- Perform BODY VERIFICATION TEST - VER 1. Body Verification Test

3. CHECK (P393) DOOR LOCK DRIVER LEFT DOORS CIRCUIT FOR A SHORT TO GROUND




Measure the resistance between ground and the (P393) Door Lock Driver Left Doors circuit.
Is the resistance below 1000.0 ohms?

No

- Go To 4

Yes

- Repair the (P393) Door Lock Driver Left Doors circuit for a short to ground.
- Perform BODY VERIFICATION TEST - VER 1. Body Verification Test

4. CHECK THE (P392) DOOR LOCK DRIVER RIGHT DOORS CIRCUIT FOR A SHORT TO THE (G778) DOOR UNLOCK DRIVER RIGHT DOORS CIRCUIT




Measure the resistance between the (P392) Door Lock Driver Right Doors circuit and the (G778) Door Unlock Driver Right Doors circuit.
Is the resistance below 1.6 ohms?


No

- Go To 5

Yes

- Repair the (P392) Door Lock Driver Right Doors circuit for a short to the (G778) Door Unlock Driver Right Doors circuit.
- Perform BODY VERIFICATION TEST - VER 1. Body Verification Test

5. CHECK THE (P393) DOOR LOCK DRIVER LEFT DOORS CIRCUIT FOR A SHORT TO THE (P5) DOOR UNLOCK DRIVER LEFT REAR CIRCUIT




Measure the resistance between the (P393) Door Lock Driver Left Doors circuit and the (P5) Door Unlock Driver Left Rear circuit.
Is the resistance below 1.6 ohms?

No

- Go To 6

Yes

- Repair the (P393) Door Lock Driver Left Doors circuit for a short to the (P5) Door Unlock Driver Left Rear circuit.
- Perform BODY VERIFICATION TEST - VER 1. Body Verification Test

6. CHECK THE (P393) DOOR LOCK DRIVER LEFT DOORS CIRCUIT FOR A SHORT TO THE (P1) DOOR UNLOCK DRIVER LEFT FRONT CIRCUIT




Measure the resistance between the (P393) Door Lock Driver Left Doors circuit and the (P1) Door Unlock Driver Left Front circuit.
Is the resistance below 2.5 ohms?

No

- Replace the Cluster.
- Perform BODY VERIFICATION TEST - VER 1. Body Verification Test

Yes

- Repair the (P393) Door Lock Driver Left Doors circuit for a short to the (P1) Door Unlock Driver Left Front circuit.
- Perform BODY VERIFICATION TEST - VER 1. Body Verification Test
