Test C1-C2:

Test C3-C5:

Test C6-C8:

Normal Operation
The interior lighting feature provides interior lighting whenever a door is ajar. The interior lamps are controlled through the SJB. The SJB provides the power and ground circuits for the dome/map lamps and the power circuits for the RH and LH footwell lamps, the RH and LH approach lamps and the RH and LH sliding door stepwell lamps. The front dome/map lamps are on separate power and ground circuits from the remaining dome/map lamps. Each footwell lamp, approach lamp and sliding door stepwell lamp has its own power circuit from the SJB. If only the rear dome/map lamps are inoperative, check the power circuit 1458 (VT/WH) and the ground circuit 1334 (OG/WH).

Possible Causes
- lamp
- SJB
- circuit 1458 (VT/WH) open or shorted to ground
- circuit 1334 (OG/WH) open, shorted to ground or shorted to power.
