Normal Operation
When a door is opened, the door ajar circuits 1312 (LG/BK) or 1314 (YE/GN) to the smart junction box (SJB) open. When the SJB identifies that the circuit is open, the SJB provides voltage to the courtesy lamps through circuit 53 (BK/LB). The door ajar switches are grounded through circuit 1205 (BK). When the dimmer control switch is rotated to the interior lamps ON position, the SJB receives a signal through circuit 2085 (VT/YE) requesting the courtesy lamps.

Possible Causes
- Circuit 53 (BK/LB) short to voltage
- Circuit 54 (LG/YE) short to ground
- Circuit 1205 (BK) open
- Circuit 1312 (LG/BK) open or short to voltage
- Circuit 1314 (YE/LG) open or short to voltage
- Circuit 2085 (VT/YE) short to ground
- Door ajar switch
- Dimmer control switch
- SJB
