Automatic test sequence
During test and assembly work faults can be recognised from other control units like e.g. plug disconnected. Therefore, on completion, the fault memories of all control units must be interrogated and erased. To do this:
–  Press key 0 twice to input the address code “Automatic test sequence” and confirm entry with Q -key. The -V.A.G 1551- transmits all known address words one after the other.
When a control unit answers with its identification the number of stored faults appears on the display or “No fault recognised”.
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.
   
The automatic test sequence has ended when following is indicated on display:
–  Erase all fault memories and then carry out a road test.
Observe the valid safety precautions when carrying out a road test → Chapter.

t  The coolant temperature must exceed 80 °C.
t  When the temperature is reached, the operating conditions idling part throttle full throttle overrun
t  At full throttle the speed must exceed 3500 rpm.
–  Again interrogate the fault memories of all control units using the “Automatic test sequence”.
