Door Ajar Warning

The chime producer activates the door ajar audible warning as requested by the IPC. The IPC sends a class 2 message to the chime producer indicating the chime duration, 4 pulses. The door ajar warning sounds and the appropriate DOOR AJAR indicator illuminates in the Driver Information Center when the following occurs:

• The body control module (BCM) determines that a door; driver door, passenger door, left rear door, right rear door, is open, signal is low. The IPC receives a class 2 message from the BCM indicating the door ajar status.
• The vehicle is not in park. The IPC receives a class 2 message from the PCM indicating the gear position.
• The vehicle speed is greater than 8.05 km/h (5 mph). The IPC uses the vehicle speed signal circuit, 4000 pulses/mile, from the PCM in order to calculate the vehicle speed.
