Chime Request Function
When the
BCM requests the instrument cluster to display a driver waring or status message, the BCM also requests a chime appropriate for that message. The instrument cluster then sends a request to the radio to sound the chime. The one exception is the seat belt indicator ON, the BCM sends a class 2 request for a chime directly to the radio.
