If there is no malfunction displayed anymore the backspace was successful.

Checking DTC memory of all control modules
During test and assembly work malfunctions can be recognized from other control modules like e.g. plug disconnected. Therefore on completion the fault memories of all control modules must be checked and erased. To do this:
- Press button 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 malfunctions appears on the display or "No fault detected".

Any system malfunctions 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.
