DTC 1501 and/or 2703 can be stored when the ignition switch is at ACCESORY (I). With the ignition switch is in ACCESORY (I), the A/C 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 1501 and/or 2703 is
stored. Check system links with the engine running, and if it shows normal, the system is OK at this time.
Rotate the interface dial to select the icon you want to diagnose. Push in the selector to see the details of that diagnostic function.
The System Links function runs automatically and displays a flashing message at the bottom of the screen reminding you to have the engine running for the test.

The results from the various components shown in the block diagram.
The microphone is tested by listening to the bong sound produced by the navigation unit from the speakers when the diagnostic is started. This requires that
the audio system be operating normally.
