Chime Systems: Notes

The Chime System is an integral part of the Body Control Module (BCM) and provides the driver with two types of chimes, Warning and Announcement. The BCM monitors its hardwired inputs and CCD bus messages to determine when a chime is needed. The Warning Chimes are a dual tone chime for the following conditions: Seat Belt Unbuckled, Exterior Lamps On, Key-In Ignition, Critical tire pressure, and Dome Lamps On. The Announcement Chime is a single tone chime to warn the driver when an instrument cluster gauge is out of range or a warning lamp is on. Refer to INSTRUMENT CLUSTER (MIC)  for more information on the Instrument Cluster gauges and warning lamps.

During shipment (with the IOD fuse disconnected) the Warning and Announcement chimes will not work with the ignition key turned off.
