Exit Illumination

The BCM grounds circuit 690 for 22-28 seconds, turning on the interior courtesy lights, when the following conditions are met:
^ The exit illumination is enabled (interior lighting mode 3 or 4). Refer to Interior Lights for more information. Lighting and Horns
^ The ignition key is removed from the ignition key cylinder (the BCM detects a transition from ground to open in circuit 80.)
^ The I/P dimmer switch is off.
^ The interior lamps override switch is on (interior courtesy lights enabled).
^ All vehicle doors are closed at the time the ignition key is removed from the ignition key cylinder (circuits 49, 54 and 159 are open).

The exit illumination is canceled when:
^ Turning the ignition switch to the ACC or RUN position.
^ Locking the doors when using either a power door lock switch or a keyless entry transmitter.
^ Re-inserting the key into the ignition cylinder within 5 seconds when exit illumination starts.
