Door Ajar Warning

The chime producer activates the door ajar audible warning as requested by the BCM. The BCM sends a serial data message to the chime producer indicating the chime frequency and duration. The door ajar warning sounds and the door ajar indicator displays in the driver information center (DIC) when the following occurs:

• The BCM determines that a door (driver door, passenger door, left rear door, right rear door) is open. The IPC receives a serial data message from the BCM indicating the door ajar status.
• The vehicle is not in PARK. The BCM receives a serial data message from the ECM/BCM indicating the gear position.
