System Links

By selecting Self-Diagnosis Mode from the navigation screen main menu. The message at the bottom of the screen flashes indicating the diagnostic is running. Make sure you enter the audio anti-theft code.
NOTE:
- The system cannot complete a full diagnosis unless the engine is running.
- DTC 2703 can be stored when the ignition switch is at ACCESSORY (I). With the ignition switch is in ACCESSORY (I), the climate control unit is turned off and the navigation unit loses communication and stores DTCs. Therefore, there is a possibility that the system is normal even DTC 2703 is stored. Check system links with the engine running, and if it shows normal, the system is OK at this time.
