The chime producer activates the key-in-ignition audible warning as requested by the body control module (BCM). The BCM sends a serial data message to the chime producer indicating the chime frequency and duration. The key-in-ignition warning sounds when the following occurs:
- The ignition switch is turned OFF. (The chime will not come on until the key is turned on and the OFF.)
- The BCM determines that the driver door is open. The IPC also receives a serial data 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 serial data message from the BCM indicating the key-in-ignition status.
