The CCN provides chime service for all available features in the chime warning system, except for the audible warning function provided by each of the optional park assist system display modules. The CCN relies on its internal programming, numerous hardwired inputs, and electronic message inputs received from other modules over the Controller Area Network (CAN) and the Local Interface Network (LIN) data buses 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 circuits between components related to the chime warning system may be diagnosed using conventional diagnostic tools and procedures. Refer to the appropriate wiring information. The wiring information includes wiring diagrams, proper wire and connector repair procedures, details of wire harness routing and retention, connector pin-out information and location views for the various wire harness connectors, splices and grounds.
However, conventional diagnostic methods will not prove conclusive in the diagnosis of the chime warning system or the electronic controls or communication between modules and other devices that provide some features of the chime warning system. The most reliable, efficient, and accurate means to diagnose the chime warning system or the electronic controls and communication related to chime warning system operation requires the use of a diagnostic scan tool. Refer to the appropriate diagnostic information.
