Interior Lighting

INTERIOR LIGHTING

The interior lighting system consists of 2 subsystems:
- Interior lamps
- Demand lamps

The interior lamps are controlled by the front electronics module (FEM). The interior lamp subsystem consists of the left and right puddle lamps, footwell lamps, map lamps and the grab handle lamps. The FEM controls the interior lamps by providing the ground circuit when a door ajar is detected.

The demand lamps subsystem consists of the glove compartment lamp, luggage compartment lamp, front map lamps, left and right vanity mirror lamps and the rear grab handle reading lamps. Each of these lamps are switched individually and share a common ground circuit.

Both subsystems use the same power supply circuit through switched system power (SSP) relay 3, with the exception of the luggage compartment lamp which is powered through SSP relay 4.
