Check and adjustment of speed of the single course / moment of ignition/concentration WITH

Within maintenance adjustment of speed of idling, the moment of ignition and concentration WITH is not required since the specified parameters are set by a control system depending on requirements.

If the valid parameters differ from set, the reason lies in malfunction of details which have to be replaced. The qualified check of a control system demands special diagnostic units.

Speed of idling can be a little changed by reprogramming of the monitor by means of the diagnostic unit.
