Interior Lighting Module: Description and Operation

How the Circuit Works

Voltage is applied at all times to the ignition key light in the steering lock through fuse 41 and to the ceiling light through fuse 46. When you open either door, the driver's multiplex control unit provides a ground for the ignition key light and ceiling light (in DOOR position) and the lights come on. The lights remain on, then fade out in about 10 seconds after both doors are closed.
