Normal Operation
SSP provides power to the interior lamps through SSP relay 2 and circuit 30-DD2 (RD/BU) between the BJB and the CJB. The interior lamp circuits are protected by CJB fuse 31 (10A). Power continues to the lamps through three circuits leaving the CJB. Circuit 29S-LB19 (OG/BU) supplies power to the dome/map lamps. Circuit 29S-LC5 (OG/BU) provides power to the AJB which connects to circuit 29S-LC11 (OG/WH) to the LH footwell lamp. Circuit 29S-LC1 (OG/BU) supplies power to the RH footwell lamp.

The ground circuit from the dome lamp, circuit 9-LB14 (BN/BU), is spliced into circuit 9-LB19 (BN/RD). The ground circuits from the LH footwell lamp, circuit 31S-LC11 (BK/WH), and the RH footwell lamp, circuit 31S-LC23 (BK/WH), are spliced together to create circuit 31S-LC4 (BK/GN).

The interior lamps ground circuits 9-LB19 (BN/RD) and 31S-LC4 (BK/GN) connect to the AJB where they are combined into circuit 29S-LC3 (OG/BU) to the FEM. The FEM provides the remaining ground connection when a lighting request is received from one of the door ajar switches or the instrument panel dimmer switch.
