To access the Dealer Engineering Mode, press the UVO hard key. Then, use a finger to touch a specific area of the head unit screen (A -> B), as shown in the image below.

After performing the A -> B procedure correctly, the Dealer Engineering screen will be displayed on the head unit. Press the eServices Check button to test system operation.

The system will display the status of various subsystems. If all subsystems are working correctly, the following message will be displayed:

“TMU, OK!” – “BT Connection, OK!” – “USB Connection, OK!” – “eServices Check, OK!”

Note: The message above indicates all subsystems are working correctly. No further action is required.

If any of the system checks fail, refer to the Troubleshooting Matrix below or to the applicable workshop manual on KGIS.
