- Press key 0 twice for address word "Automatic test sequence" and confirm entry with Q button. The V.A.G 1551 transmits all known address words one after the other.

When a control module answers with its identification the number of stored DTCs appears on the display or "No DTC recognized".

Any system faults that are stored will be displayed one after the other and printed out. The V.A.G 1551 will then transmit the next address word.
