Test C: A Single Door Lock Is Inoperative

PINPOINT TEST C: A SINGLE DOOR LOCK IS INOPERATIVE

C1-C2:

Normal Operation
The door lock control switches supply a signal to the smart junction box (SJB). When the SJB receives a door lock control switch lock command through circuit 1088 (PK/WH), it supplies voltage to the door lock actuators through circuit 117 (PK/BK) while grounding circuits 118 (PK/OG) and 163 (RD/OG) to lock all the doors. When the SJB receives a door lock control switch unlock command through circuit 1088 (PK/WH), it supplies voltage to the door lock actuators through circuits 118 (PK/OG) and 163 (RD/OG) while grounding circuit 117 (PK/BK) to unlock all the doors. The driver and passenger door lock control switch circuits are spliced together within the wiring harness.

Possible Causes
- Circuit 117 (PK/BK) open
- Circuit 118 (PK/OG) open
- Circuit 163 (RD/OG) open
- Door latch
- Liftgate latch actuator
- SJB (LH front door lock only)
