Door Activated Courtesy Lighting

The interior lamp switch must be in the AUTO position. When a door is opened, the respective door lock actuator contacts close. The door module Door Open Input is grounded. In response to this input, the door module sends a class 2 message to the Rear Integration Module (RIM) indicating that a door is open. If the ambient light sensor indicates nighttime conditions, the RIM will activate the INT LP relay.

The RIM will continue to keep the courtesy lamps on for 25 seconds after all doors are closed. The courtesy lamps will turn off immediately it the ignition switch is turned to the ON position, the interior lamp switch is placed in the OFF position, or an all doors lock command is issued with all doors closed.
