the instrument cluster circuitry. The check gauges indicator may be illuminated when any critical engine or transmission systems are operating
outside of their normal parameters. The instrument cluster monitors electronic messages received over the CAN data bus to determine when to
illuminate the check gauges indicator.
The CCN provides chime service for all available features in the chime warning system. The CCN relies upon its internal programming, numerous
hardwired inputs, and electronic message inputs received from other modules over the CAN data bus network to provide the chime warning system
features. The internal programming of the CCN determines the priority of each chime request input that is received, as well as the rate and duration of
each chime that is to be generated.
The hardwired chime warning system inputs to the CCN may be diagnosed and tested using conventional diagnostic tools and procedures. However,
conventional diagnostic methods may not prove conclusive in the diagnosis of the CCN, the CAN data bus, or the electronic messages received by the
CCN from other modules. The most reliable, efficient and accurate means to diagnose the CCN, the CAN data bus, or the electronic message inputs used
for the chime warning system requires the use of a diagnostic scan tool. Refer to the appropriate diagnostic information.
