Key-In-Ignition Warning

The chime producer activates the key-in-ignition audible warning as requested by the IPC. The IPC sends a class 2 message to the chime producer indicating the chime frequency 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 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 closed and the signal circuit is low. The IPC receives a class 2 message from the BCM indicating the key-in-ignition status.
