Normal Operation
The smart junction box (SJB) monitors the door ajar switch status on circuits 759 (LG/YE), 760 (PK/LB), 761 (GY/RD) and 765 (YE/BK) for a ground supplied through the ajar switches by circuit 57 (BK) indicating an open door. The SJB then grounds the control side of the battery saver relay and the interior lamp relay. When the relays are energized, voltage is supplied to the interior lamps through circuit 53 (BK/LB).

Possible Causes
- Fuse(s)
- Circuit 53 (BK/LB) open
- Circuit 1052 (TN/BK) open
- SJB
- Headlamp switch
