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 also monitors the instrument panel dimmer switch on circuit 1008 (LG/OG). Based on these inputs, 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
- Circuit 53 (BK/LB) short to voltage
- Circuit 1008 (LG/OG) short to ground
- Circuit 759 (LG/YE) short to ground
- Circuit 760 (PK/LB) short to ground
- Circuit 761 (GY/RD) short to ground
- Circuit 765 (YE/BK) short to ground
- Door ajar switch(es)
- Headlamp switch
- SJB
