Normal Operation
The interior lighting feature provides interior lighting whenever a door is ajar. The interior lamps are controlled through the FEM. The FEM provides the ground circuit for the front dome/map lamps, rear grab handle lamps, RH and LH footwell lamps and the RH and LH puddle lamps through common circuit 29S-LC3 (BK/OG). Power for the interior lamps is supplied through common circuit 29S-LB2 (OG/BU) from switched system power (SSP) relay 3.

Possible Causes
- battery junction box (BJB)
- circuit 29S-LC23 (OG/WH) open
- circuit 31S-LC3 (BK/OG) short to power
- circuit 31-DK20 (BK/RD) open
- FEM
