Description And Operation: Operation: Notes

The audio system components are designed to provide audio entertainment and information through the reception, tuning and amplification of locally broadcast radio signals in both the Amplitude Modulating (AM) and Frequency Modulating (FM) commercial frequency ranges. If the vehicle is so equipped, the audio system can also receive, amplify or process certain cellular, satellite audio and satellite Global Positioning System (GPS) radio signals. The audio system components operate on battery current received through a fuse in the BCM.

The optional navigation radio system receives GPS signals from up to eight satellites to display the position and direction of the vehicle. An electronic gyro-sensor and the speed sensor in the vehicle enable the system to display the present vehicle position even in locations where GPS signals may be blocked. When a destination is selected, the navigation system uses information from the map to quickly calculate a route. As the vehicle is driven along the chosen route, the operator is guided with pictorial displays and voice prompts.

The hard wired circuits between components related to the audio system may be diagnosed using conventional diagnostic tools and procedures. Refer to the appropriate wiring information. The wiring information includes wiring diagrams, details of wire harness routing and retention, connector pin-out information and location views for the various wire harness connectors, splices and grounds. For proper wire repair, and connector repair procedures. Refer to STANDARD PROCEDURE . and. Refer to REMOVAL . Refer to INSTALLATION .

However, conventional diagnostic methods will not prove conclusive in the diagnosis of the audio system or the electronic controls and communication between modules and other devices that provide some features of the audio system. The most reliable, efficient and accurate means to diagnose the audio system or the electronic controls and communication related to audio system operation requires the use of a diagnostic scan tool. Refer to the appropriate diagnostic information.
