Courtesy Lamp: Description and Operation

COURTESY LAMP CONTROL
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, opening a door or if the RKE activates the BCM 30 second illuminated entry timer. The interior lamps will then fade to off over a 5 second period.

Reading Lamps
The reading lamps and control switches are mounted on the rear view mirror.

Interior Lamp Battery Protect Feature (Load Shedding)
To protect the battery from excessive current draw, the courtesy, halo, reading and glove box lamps are shut oft after 15 minutes if they have been left ON or a door has been left ajar after the ignition key is removed from the ignition. This is accomplished by the BCM which removes ground from these lamps.
