PINPOINT TEST A: THE INTERIOR LAMPS ARE INOPERATIVE


Test A1-A2:






Test A3-A5:






Normal Operation
When a door or the liftgate is closed, the ajar switch grounds the circuit from the vehicle security module. The vehicle security module monitors the door ajar switch status and transmits a dome lamp on signal to the instrument cluster indicating an entry point is open. The instrument cluster energizes the courtesy lamp circuits, lighting the courtesy lamps.

Possible Causes
- vehicle security module
- instrument cluster
- fuses
- circuit 3049 (BK/LG)
- circuit 1203 (BK/LB)
