Normal Operation
The central junction box (CJB) supplies voltage to the LH and RH door lock control switch through circuit 1524 (DB). The driver door module (DDM) receives lock or unlock requests from the door lock control switches on circuits 119 (PK/YE) and 120 (PK/LG). The DDM supplies voltage on circuit 117 (PK/BK) to the door lock actuators if a lock command is received or voltage on circuits 163 (RD/OG) (driver door) and 118 (PK/OG) (passenger door) if an unlock command is received.

DTC B1396 - sets when the power door lock circuit is shorted to voltage.

DTC B1397 - sets when the power door unlock circuit is shorted to voltage.

Possible Causes
- Fuse
- Circuit 117 (PK/BK) open
- Circuit 119 (PK/YE) short to voltage or ground
- Circuit 120 (PK/LG) short to voltage or ground
- Circuit 1524 (DB) open
- Door lock control switch
- DDM
