Does the test light illuminate brightly on both sides of the fuse?

No

- Repair the open circuit as necessary. If the fuse is blown, replace it and try the locks. If it blows again, use the schematics and locate and repair the short circuit.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

Yes

- Go To 3

3. (A 932) FUSED B+ CIRCUIT OPEN




1. Disconnect the Instrument Cluster C1 connector.
2. Measure the voltage of the (A932) Fused B+ circuit in the Cluster C1 connector.

Is the voltage above 11.0 volts?

Yes

- Go To 4

No

- Repair the (A932) Fused B+ circuit for an open.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

4. (P33) DOOR LOCK DRIVER WIRE OPEN




1. Disconnect any Door Latch Connector.
2. Measure the resistance of the (P33) Door Lock Driver wire between the Cluster C1 connector and the door latch connector.

Is the resistance below 5.0 Ohms?

Yes

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

No

- Repair the (P33) Door Lock Driver wire for an open.
- Perform the BODY VERIFICATION TEST. Body Verification Test.
