Door/Trunk Ajar Indicator/Lamp: Description and Operation
CIRCUIT OPERATION
Each door and the liftgate have an ajar switch that connects to the Body Control Module (BCM). The BCM senses when the liftgate or a door
opens, and sends the a signal to the VIC on the CCD bus. In response, the VIC displays which door is open. The VIC communicates with the BCM
over the CCD bus on circuits D1 and D2.
