11.14. Adjustment of turns of idling and the contents WITH in exhaust gases

GENERAL INFORMATION

For check of turns of idling and the contents WITH in exhaust gases application of an exact tachometer and the analyzer of exhaust gases is necessary. If the measured sizes do not correspond to demanded values, adjustment is necessary for making at service station with use of the special diagnostic equipment. As neither idling turns, nor the contents WITH are not regulated manually.

The diagnostic socket for connection of the special equipment is located in a plait of wires of a control system the engine. Use of the special equipment allows easily and to define quickly malfunction in a control system of the engine. Check of a control system by the engine without the special equipment by process of elimination takes a lot of time and not always yields positive results. Thus there is a probability of damage of the electronic ECU control unit.
