Yes
- Go To 3
3. (A 932) FUSED B+ CIRCUIT OPEN
Disconnect the Instrument Cluster C1 connector.
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 BODY VERIFICATION TEST - VER 1. (Refer to 8 - ELECTRICAL/ELECTRONIC CONTROL MODULES - STANDARD PROCEDURE)
4. (P33) DOOR LOCK DRIVER WIRE OPEN
Disconnect any Door Latch Connector.
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 in accordance with service information.
- Perform BODY VERIFICATION TEST - VER 1. (Refer to 8 - ELECTRICAL/ELECTRONIC CONTROL MODULES - STANDARD PROCEDURE)
No
- Repair the (P33) Door Lock Driver wire for an open.
