Pinpoint Test 3

PINPOINT TEST 3: THE INTERIOR LAMPS DO NOT TURN ON WITH ONE DOOR OPEN

Normal Operation
When any door is opened, the door ajar switch closes and signals the smart junction box (SJB). The SJB receives the door open signal and activates the interior lamp relay (integral to the SJB) and applies voltage to circuit (B/LB).

Possible Causes
- Circuit (B) open
- Circuit (GY/R) open
- Circuit (Y/B) open
- Door ajar switch
- SJB
