Checks of system of injection of fuel

Before starting to work, familiarise with the safety measures resulted in Section the General data and security measures.

At failure detection of system of injection of fuel first of all be convinced of reliability of joining of all sockets and absence on their surfaces of traces of corrosion. Further be convinced that malfunction is caused not by neglect regular service (check up an air cleaner, working backlashes of valves, a compression in cylinders, the fuel filter). Be convinced also that hoses of system of ventilation картера are not blocked.

If after carrying out described before checks the cause of defect is not found out, drive away the car on HUNDRED diagnostics for carrying out. In the bottom part of the instrument panel from outside the driver there is a diagnostic socket which the special diagnostic equipment joins. This equipment reads out the codes of malfunctions fixed in memory of the block of management.

Codes of malfunctions can be считаны by means of the special diagnostic scanner which is available on HUNDRED, or personal computer with a special payment, the program and a cable.

By means of reading of codes you can easily find out malfunction even if it is not obvious. You can check up any knot without application of the diagnostic scanner of codes, but keep in mind that nonprofessional intervention in system can lead to damage of electronic knots.

If at your order there is a diesel tachometre or other suitable equipment, you can measure idling turns. But adjustment of these parametres is not made. As a reason for rejection of turns of idling faulty atomizers can serve. In this case they are necessary for clearing and откалибровать. Service life of atomizers is unlimited, but can happen so that you should repair or replace them after run approximately 100000 kilometres. The expert should carry out repair and calibration of atomizers.
