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

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

This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- Door ajar switch
- SJB
