A5-A7:

Normal Operation
Power is supplied to the smart junction box (SJB) through circuit 1695 (YE/WH). When any door, liftgate, or liftgate glass is opened, the ajar switch opens, signaling the SJB. The SJB monitors the ajar circuits, and based on the ajar status, the SJB will supply voltage to the interior lamps on circuit 1005 (VT/OG), and ground through circuit 401 (PK).

Possible Causes
- Fuse
- Circuit 401 (PK) open or short to voltage
- Circuit 1005 (VT/OG) open or short to ground
- Circuit 1695 (YE/WH) open
- SJB
