PINPOINT TEST A: THE INTERIOR LAMPS ARE INOPERATIVE

Test A1:

Test A2-A3:

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 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 all interior lamps are inoperative the only common component is the SJB.
