Courtesy Lamp Control

The Body Control Module (BCM) has direct control over the majority of the vehicle's courtesy lamps. The BCM will illuminate the courtesy lamps under any of the following conditions:

- Any door is ajar.
- The courtesy lamp switch on the instrument panel is closed.
- A Remote Keyless entry unlock message is received. If the interior lamps are left on after the ignition is turned off, the BCM will turn them off after 1 hour or until either the dome lamp switch or door ajar switch changes state.
