INTERIOR ILLUMINATION

DESCRIPTION

General
Interior illumination provides background lighting for the instrument pack and control switch graphics. Interior illumination operates when the lighting switch is turned to the side or headlamp position, irrespective of ignition switch position.

OPERATION

General
Feed from the positive battery terminal (C0192) is supplied to fusible link 12 of the engine compartment fuse box (C0632) on an R wire. Fusible link 12 (C0575) is connected to the lighting switch (C0041) by an RN wire. When the lighting switch is turned to the side or headlamp position, current flows across the switch (C0041) to fuse 16 of the passenger compartment fuse box (C0587) on an R wire.
