In order to carry out a diagnosis on the vehicle or to be able to connect a tester to the OBD2-Port, the DataDisplay must be disabled/locked.
(If the OBD2-Blocker is activated in the settings, deactivate it first)
To lock the DataDisplay, press the lock symbol in the main menu.
If not already done, enter a 4-digit PIN (0000 is not allowed). Repeat the PIN to make sure that you have not mistyped.
Then the DataDisplay is locked and the OBD2-Port can be used by external devices.
ATTENTION F-Series: In the F-Series, turn the ignition off and lock the car once. Open the car again and the OBD2-Port is released for other devices.
When the use of the OBD2-Port is finished, the DataDisplay can be unlocked again with the self-selected 4-digit PIN.
