PINPOINT TEST H: THE INTERIOR LAMPS DO NOT TURN ON WITH ONE DOOR OPEN

Test H1-H2:

Test H3:

Normal Operation
The vehicle security module monitors the door ajar switch status on circuits 700 (WH/VT), 759 (LG/YE), 760 (PK/LB), 761 (GY/RD), 765 (YE/BK) and 1351 (TN) for a ground supplied through the ajar switches by circuit 1205 (BK) indicating an entry point is closed. The vehicle security module transmits information over the UBP network to indicate a door open condition. The instrument cluster then energizes the courtesy lamp circuits, lighting the courtesy lamps.

Possible Causes
- vehicle security module
- instrument cluster
- circuit 1205 (BK)
- ajar switches
