Door Ajar Warning
WARNING: This page is about a different car, the 2002 Oldsmobile Aurora and 2001 Oldsmobile Aurora. However, it is still accessible from the selected car via links, so may be relevant.
The radio activates the door ajar audible warning as requested by the IPC. The IPC sends a class 2 message to the radio indicating the chime frequency and the duration. The door ajar warning sounds and the DIC displays the XX DOOR AJAR message when the following occur:
- The driver door module (DDM) detects that the driver door is open (signal circuit is low). The IPC receives a class 2 message from the DDM indicating the door ajar status.
- The IPM detects that the key is in the ignition. The IPC receives a class 2 message from the IPM indicating the key-in-ignition status.
- The vehicle is not in park or neutral. The IPC receives a class 2 message from the PCM indicating the gear position.
