Chime System
WARNING: This page is about a different car, the 2002 Dodge Stratus and 2002 Chrysler Sebring. However, it is still accessible from the selected car via links, so may be relevant.
The chime system is comprised of an audible chime located internal to the BCM, and is dependent on various inputs to the BCM to operate. These inputs to the BCM include key-in ignition switch, exterior lamps as well as requests for the Mechanical Instrument Cluster from the seat belt switch input or whenever certain indicators are turned on.
