Start-up procedure and Diagnostic Menu

There are two ways to enter the diagnostic mode:
1. Connect the SCS connector to the navigation service connector located in the trunk. Turn the ignition switch to the ON (II) position. The display will go directly to the diagnostic menu screen shown below.

NOTE: When finished troubleshooting, make sure to remove the SCS connector.




2. Turn the ignition switch ON (II). Use the navigation display hard buttons as described below:
Make sure the battery is connected, then press and hold the three buttons (Menu, Map/Guide, and Cancel), and keep them pressed for approximately 5 seconds. The display screen will go directly to the "Select Diagnosis Items" menu shown above.
3. After the display changes to the Select Diagnosis Items menu, select the item you want to check and the diagnostic will start. To return to the previous screen, select "RETURN".

Factory diagnostic screen "In Line Diag"

When a navigation control unit is powered up for the first time at the factory, the "factory diagnosis" screen (In Line Diag) shows up. Normally the factory performs the steps necessary to verify proper operation and terminate the "factory diagnostic". Until the proper confirmation sequence is performed, the screen will show up every time the vehicle is started.
Follow the steps below to prevent the screen from showing up in the future:
- Hold down the buttons (Menu + Map/Guide + Cancel) for about 5 seconds (the "Select Diagnosis items" screen will appear).
- Hold down the Map/Guide button for 5-10 seconds (A screen with a "Complete" button, will appear).
- Touch "Complete", and then the "Return" button (the system may re-boot).
- Restart the vehicle, and confirm normal operation by completing the "TQI of the Navigation System" Service Bulletin.
