Click on Brief test.
The brief test is carried out.

Note:
For motor vehicle diagnostics, the brief test is essential for evaluating possible stored diagnostic trouble codes. In the brief test, the control units are physically identified in succession and their fault memories read out.
If the fault memory has been read out, the faults appear in the "Fault pattern selection" mask in the "Fault memory contents" field.
