6.3.2. Checks of system of injection of fuel

Before starting to procedure performance, familiarize with the precautionary measures given in the Section General information and security measures.

At identification of signs of violation of serviceability of functioning of system of injection of fuel, first of all check reliability of a tightening of all shtutserny connections of a path of a power supply system. Make sure that a cause of infringement is not the elementary neglect to performance of procedures of regular service, - check a condition of an air purifier and the fuel filter, make measurement of working gaps of valves, kompressionny pressure in cylinders, etc. Make sure of passableness of hoses of system of ventilation of a case (see. Head Current leaving and service).

If after carrying out listed above checks to reveal a cause of infringement it is not possible, drive away the car on HUNDRED pains for carrying out detailed diagnostics, - in the lower part of the dashboard from the driver there is a diagnostic DLC socket for connection of the special scanner by means of which reading of codes of the malfunctions (DTC) revealed by system of onboard self-diagnostics and brought in memory of the processor of the module of management is made.

Alternatively reading of the DTC codes can be made by means of the personal computer equipped with a special payment with the established software, - for computer connection to the DLC socket the special cable is used. By reading of codes the operator can easily reveal even the hidden refusals.

Remember that any nonprofessional intervention in the device of a control system is interfaced by the engine to risk of irreversible failure of electronic components!

Turns of idling of the engine can be measured by means of the special tachometer intended for use on diesel engines, however adjustment of this parameter is not represented possible. From adjusting value violation of serviceability of functioning of nozzles which should be in this situation cleared and откалиброваны can be a reason for rejection of turns of idling. Service life of nozzles is unlimited, however at excess by run of the car of 100 000 km the probability of their refusals raises, - it is necessary to charge performance of procedures of regenerative repair and calibration of nozzles to specialists of car-care center.
