Operation CHARM: Car repair manuals for everyone.

Keyless Entry Interior Illumination

When the driver uses the remote function actuator transmitter to unlock the doors or rear compartment, the BCM will illuminate the courtesy lamps for approximately 40 seconds. When the courtesy lamps are illuminated, and the door locks are activated to the UNLOCK or LOCK position, or if the ignition switch is turned to either the RUN or CRANK position the courtesy lamps will turn off immediately.
