Door Ajar Warning

The audio amplifier activates the door ajar audible warning as requested by the IPC. The IPC sends a serial data message to the radio indicating the chime frequency. The door ajar warning sounds and the door ajar message is displayed in the DIC when the following occurs:

• The IPC determines that the driver door is open and the signal circuit is low. The IPC also displays the appropriate door ajar message in the DIC.
• The vehicle is not in PARK. The IPC receives a serial data message from the BCM indicating the gear position.
