Normal Operation
The smart junction box (SJB) supplies voltage to the lock all relay, the unlock driver door relay or unlock all relay based upon input from the door lock control switches, the remote keyless entry (RKE) transmitter, or the keyless entry keypad. When the SJB supplies voltage to circuit CPL52 (VT/GY) (RH front, LH rear, RH rear doors), CPL51 (BU/GN) (LH front door) and ground through circuit CPL11 (GY/BN), the door latches unlock the doors. When the SJB supplies voltage to circuit CPL11 (GY/BN) and ground through circuit CPL52 (GY/BN) (RH front, LH rear, RH rear doors) and circuit CPL51 (BU/GN), the door latches lock the doors.

Possible Causes
- Circuit CPL11 (GY/BN) open
- Circuit CPL51 (BU/GN) open
- Circuit CPL52 (VT/GY) open
- Door lock actuator (part of the door latch)
- SJB
