Chime Service: Notes

WARNING: This page is about a different car, the 2003 Jeep Liberty. However, it is still accessible from the selected car via links, so may be relevant.

The EMIC is equipped with hardware and software to provide chime service for all available features in the chime warning system. Upon receiving the proper chime inputs, the EMIC activates an integral on-board audible tone generator to provide audible chime tones to the vehicle operator. The chime tone generator in the EMIC is capable of producing single chime tones or repeated chime tones at two different rates: a slow rate of about fifty chime tones per minute, and a fast rate of about 180 chime tones per minute. The internal programming of the EMIC determines the priority of each chime tone request input that is received, as well as the rate and duration of each chime tone that is to be generated.

The EMIC is programmed to provide chime service when certain indicators are illuminated. In addition, the EMIC is programmed to provide chime service for other electronic modules in the vehicle when it receives the proper electronic chime request messages over the Programmable Communications Interface (PCI) data bus. (Refer to CHIME WARNING SYSTEM ).

The hard wired chime inputs to the EMIC and the Body Control Module (BCM) may be diagnosed using conventional diagnostic methods. However, proper testing of the EMIC programming and the electronic chime request messages received by the EMIC over the PCI data bus requires the use of a DRBIII(R) scan tool. Refer to the appropriate diagnostic information.
