Key-In-Ignition Warning

The chime producer activates the key-in-ignition audible warning as requested by the body control module (BCM). The BCM sends a GMLAN message to the chime producer indicating the chime frequency of a medium rate and continuous duration. The key-in-ignition warning sounds when the following occurs:

• The ignition switch is OFF.
• The BCM determines that the driver door is open and the signal circuit is low. The IPC also receives a GMLAN 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 GMLAN message from the BCM indicating the key-in-ignition status.
