–  Perform test as described in the relevant repair sequences.
  Note
t  After re-connecting the engine control unit perform the following:
t  Adapt the engine control unit to the throttle valve control unit → Chapter.
t  Adjust the kick-down function for vehicles with an automatic gearbox → Chapter.
t  Interrogate fault memory and if necessary erase → Chapter.
For engines with engine identification characters ARX and AUM
–  Whenever the fault memory is erased, it is necessary to generate a readiness code → Chapter.
