Normal Operation
The smart junction box (SJB) monitors circuits 119 (PK/YE), 120 (PK/LG), 1296 (OG/BK) and 1297 (YE/RD) for a ground signal. If the door lock control switch connects circuit 119 (PK/YE) (driver door) or 1296 (OG/BK) (passenger door) to the ground circuit 57 (BK) the doors lock. If the door lock control switch connects circuit 120 (PK/LG) (driver door) or 1297 (YE/RD) (passenger door) to the ground circuit 57 (BK) the doors unlock.

Possible Causes
- circuit 57 (BK) open
- circuit 119 (PK/YE) open or short to ground
- circuit 120 (PK/LG) open or short to ground
- circuit 1296 (OG/BK) open or short to ground
- circuit 1297 (YE/RD) open or short to ground
- driver door lock control switch
- passenger door lock control switch
