PINPOINT TEST D: THE COURTESY LAMPS DO NOT TURN ON WITH ONE DOOR OPEN


D1-D5:






Normal Operation
When any door is opened, the ajar switch opens the circuit to the smart junction box (SJB). The SJB monitors the ajar circuits, and based on the ajar status, the SJB will supply voltage to the courtesy lamps on circuit VLN33 (GY/VT).

Possible Causes
- Circuit CPL26 (GN/VT) short to ground
- Circuit CPL31 (WH) short to ground
- Circuit CPL36 (GN) short to ground
- Circuit CPL39 (YE) short to ground
- Ajar switch
- SJB
