Key In Ignition Reminder

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 of a medium rate and at a continuous duration. 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 and the 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 open and the signal circuit is high. The IPC receives a class 2 message from the BCM indicating the key-in-ignition status.
