Courtesy Lamp Control: Notes
The interior courtesy lamps located in the right and left foot well area, the rear view mirror and the ignition switch halo lamp are hardwired together and are controlled by the BCM. They can be activated by the dome lamp switch, by opening a door or by the RKE when it activates the BCM 30 second illuminated entry timer. The interior lamps will then fade to off over a 5 second period.
