Door Ajar Warning

Radio activates door ajar audible warning as requested by Body Control Module (BCM). BCM sends a class 2 message to radio, indicating chime frequency of a medium rate and at a continuous duration. Door ajar warning sounds and DOOR AJAR indicator illuminates when following occurs:

• BCM determines that driver's door is open and signal circuit is low. Instrument Panel Cluster (IPC) receives a message via class 2 from BCM requesting illumination of DOOR AJAR indicator.
• The vehicle is not in Park. BCM receives a class 2 message from PCM indicating gear position.
