Diagnostic System Diagram
This diagram below shows all of the navigation diagnostic features available for system troubleshooting. The diagram starts at the center, and works outward in layers.
Access to the diagnostic features begins by starting the vehicle. This is necessary so the system can check the other systems connected by various busses. After starting the vehicle you can enter the diagnostic mode by pressing and holding the MENU, MAP/GUIDE, and CANCEL buttons.
The main menu screen allows 2 checking modes - one automatic, and one manual:
- The automatic diagnostic check starts when you select "SELF DIAGNOSTIC MODE". The system runs for several seconds, and reports any issues with Red icons. Use the joystick or touch screen and select the icon you wish obtain the problem details.
- The manual diagnostic check is selected from the main menu by selecting "DETAIL INFORMATION AND SETTING". The traditional diagnostic menu is displayed. This allows you to obtain additional details as instructed in the troubleshooting procedures.
