Doors: Description and Operation

DOOR AJAR INDICATOR
The IPC illuminates the DOOR AJAR indicator in the message center when the Body Control Module (BCM) detects that the driver or passenger door is open. The IPC receives a class 2 message from the BCM requesting illumination. If the vehicle is in a forward or reverse gear position, the BCM sends a class 2 message to the radio in order to activate an audible warning.
