Normal Operation
The SJB provides the power circuits for the demand lamps. There are three separate power circuits to the demand lamps. The first, circuit 705 (LG/OG) supplies power to the front dome/map lamps. Next is circuit 1458 (VT/WH) which supplies power for the second row and third row dome/map lamps. Finally circuit 53 (BK/LB) supplies power to the RH and LH vanity mirror lamps. All of the demand lamps share in a common ground, circuit 1205 (BK).

Possible Causes
- circuit 705 (LG/OG)
- circuit 1458 (VT/WH)
- circuit 53 (BK/LB)
- circuit 1205 (BK) open
- demand lamp
- SJB
