There isn't a chime module , built into instrument cluster !
Door Ajar Chime
The door ajar chime feature is controlled by the smart junction box (SJB). The driver and passenger door ajar switches, and the lift gate are hardwired to the SJB. If any door or lift gate is sensed as being open, and the ignition switch is in RUN/START position, the SJB will process the input and sends a chime request to the instrument cluster over the controller area network (CAN).
Safety Belt Warning Chime
The safety belt chime feature is controlled by the restraints control module (RCM). The driver safety belt switch is hardwired to the RCM. The RCM communicates with the instrument cluster over a hardwire connection. If at any time during the first 6 seconds after the ignition switch is placed in RUN the driver safety belt is sensed as being unfastened, the RCM will process the input, and in turn, sends a chime request to the instrument cluster.
Do you know what C.A.N controller area network is ? Serial data communication bus.
