Operation CHARM: Car repair manuals for everyone.

Lighting With Switches

The IP compartment lamp, the rear compartment lamp, courtesy/reading lamps, and all vanity mirrors each have a switch on the ground side of the lamp. When the inadvertent power output of the Body Control Module (SBM) is inactive, activating a switch will ground the inadvertent power input. This tells the SBM to activate the inadvertent power output, which supplies power to the interior lamps. Any lamp with an active switch will then turn on.
