Frequency of rotation of a cranked shaft of the petrol engine makes 900 mines-1 and is established by the management block on turbodiesel engine Endura of 850 mines-1.

The number of turns of idling constantly by means of a servomotor, after inclusion (for example, headlights, the conditioner or the steering amplifier) is calibrated by the management block. Focus with the petrol engine works on 900 rpm, Endura-Turbodiesel rotates a cranked shaft about 850 rpm. For the preventive control the exact device is necessary for measurement of turns for you. Workshops use an autotester for this purpose. If the number of turns does not correspond to factory parametres, they cannot be adjusted separately. It is necessary to search for the failure reason in all control system. If the storage battery has been disconnected, it is required to pass not less than 2-8 km that in memory of the block of management the old data was restored. Otherwise operate as follows:

- Check up a condition of hoses for air intake;

- Check up an accelerator drive, whether hard it;

- The further control spend in workshops with application of special autotesters for engine check;

- Absence of pressure in fuel system can cause unstable idling. Check of size of pressure spend in a workshop.
