Normal Operation
When the smart junction box (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 door lock control switch and passenger door lock control switch circuits are spliced together within the wiring harness. The SJB is provided ground through circuit 57 (BK).

Possible Causes
- Circuit 57 (BK) open
- Circuit 117 (PK/BK) open or short to ground
- Circuit 118 (PK/OG) open or short to ground
- Circuit 1088 (PK/WH) open or short to ground
- Door lock control switch
- SJB
