Perform vehicle system test

Connect the diagnostic unit, → Diagnostic testing unit, connecting .
Switch ignition on.
Select operating mode "Guided Fault Finding" on the display.
Then perform vehicle identification on tester.

Program now performs a vehicle system test automatically and checks for all possible control modules for this vehicle type.

Press Continue > button.

Now all DTCs will be listed.

At this point it makes sense to switch into operating mode Guided Functions in order to perform further work using VAS 5051 and to prevent a second vehicle identification on the tester.
To do so, press operating mode button and then Guided Functions.
Refer to the corresponding work descriptions for the continued sequence.
In order to return to Guided Fault Finding, press the operating mode button and then Guided Fault Finding.

WARNING: In any case, the vehicle must be returned to the customer with DTC memory erased.

Static malfunction

If one or more static malfunctions are stored in data memory, it is recommended to arrange with the customer to repair this malfunction via Guided Fault Finding.

Sporadic malfunctions

In the event only sporadic malfunctions or notes are stored in DTC memory and the customer has made registered no complaint in conjunction with an electronic vehicle system, erase DTC memory.

Press the Continue > button again to enter the test plan.
Now end Guided Fault Finding via Go to button and then End.

All DTC memories will be checked now once more.

The window that now appears confirms that all sporadic faults were cleared.

Then the diagnostic protocol is sent "online" or stored on the tester.

NOTE:

If tester is not connected to the network, diagnostic protocol is stored and the transmission follows as soon as tester is connected to the network.
Protocols that have been stored and are older than four days are erased automatically.

Vehicle system test is completed.
