| Diagnosis and Testing Worldwide Diagnostic System (WDS) Inspection and Verification NOTE:If the navigation system display module displays either of the following: - serial number(s) are incompatible
- vehicle identification number (VIN) does not match
NOTE:Use the WDS to configure the navigation system display module and the navigation digital versatile disc (DVD) unit to each other. - Verify the customer concern.
- Visually inspect for obvious signs of mechanical or electrical damage.

| - If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step.
- If the cause is not visually evident, refer to the Self-Diagnostic Mode.
Self-Diagnostic Mode NOTE:It is necessary to carry out part of the system diagnosis outside the workshop. Make sure that there are no large buildings/obstructions or metal objects in the immediate vicinity. - Turn the ignition switch to position II.
- To access the diagnostic menu, PRESS and HOLD the MENU button for approximately 10 seconds, until a audible beep is heard and the screen changes to the personal identification number (PIN) number display.
- ENTER the following PIN number on the display to access the additional diagnostic menus: 6414.
- PRESS the ENTER button on the display screen to confirm PIN number input.
The display screen will show the following sub-menu(s): - General Info
- Manual Check
- Display Info
- Navigation Info
- S/W Update
- Self Check
- TOUCH the display screen to select the required sub-menu.
Additional menus can be accessed from the following sub-menus: General Info This sub-menu contains vehicle configuration information. The additional menus from this sub-menu are as follows: - Audio Diagnostics - Allows audio unit diagnosis
Manual Check This sub-menu allows access to key test screens. The additional menus from this sub-menu are as follows: - DIAGNOSTIC ERROR CODES - This will display a list of all set diagnostic trouble codes (DTC)s.
- NAV RGB TEST - Display color confirmation.
- TOUCH SCREEN CHECK - Allows the display touch calibration.
- DISPLAY HARDKEY CHECK - On screens icons are illuminated when a hard key is pressed.
Display Info This sub-menu contains software version information for the display. Navigation Info This sub-menu allows access to the global positioning system (GPS) information screens. The additional menus from this sub-menu are as follows: - RESET POSITION - Allows the vehicle position to be reset to the current map DVD default country (Belgium).
- VEHICLE/GYRO SIGNALS - Displays the vehicle direction, speed and distance. Also displays the gyro information.
- GPS INFORMATION - Displays the GPS satellites signals to the navigation system and their position.
S/W Update This sub-menu allows the update of the navigation system DVD unit software from a separate DVD ROM sent when an update is required and is available. This cannot be done from the normal navigation system DVD ROM. Self-Check This sub-menu displays error codes detected after an internal self-diagnostic check of the navigation DVD unit. - Turn the ignition switch to position 0 to exit the diagnostic menu.
- If the cause is not visually evident after the Self-Diagnostic Mode, connect the WDS to the data link connector (DLC).
- Retrieve the DTCs and refer to the DTC Index Chart.
