Key In Ignition Reminder

The IPC activates the key-in-ignition audible warning as requested by the BCM. The BCM sends a class 2 message to the IPC 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 Body Control Module (BCM) determines that the driver's door is open (signal circuit is low). The IPC receives a class 2 message from the BCM indicating the door ajar status.
^ The BCM determines that the key-in-ignition switch is closed (signal circuit is low). The IPC receives a class 2 message from the BCM indicating the key-in-ignition status.
