Key-In-Ignition 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 key-in-ignition audible warning as requested by the IPC. The IPC sends a class 2 message to the radio indicating the chime frequency (medium rate) and duration (continuous). The key-in-ignition warning sounds when the following occurs:
- The ignition switch is OFF.
- The driver door module (DDM) detects that the driver door is open (signal is low). The IPC receives a class 2 message from the DDM indicating the door ajar status.
- The instrument panel integration module (IPM) determines that the key-in-ignition switch is open (signal is high). The IPC receives a class 2 message from the IPM indicating the key-in-ignition status.
