Diagnostics of malfunctions

The description of diagnostics of electronic control systems and codes of malfunctions are resulted in the Head of System of an electric equipment of the engine.

In the given section the most simple scheme of finding-out of the reasons of malfunctions and the refusals occurring in knots and systems of the car is offered. Refusals and their possible reasons are broken into groups on the basis of the relation to certain components or car systems, as for example the engine, cooling system, etc., besides, in the text references to chapters and the sections concerning given problems are given.

Remember that successful end of search of causes of defect is defined by integrity of a complex of good knowledge and the patient, regular approach to problem research. To move always follows from simple to difficult, to lead up each check to the logic end and to try not to pass the obvious facts - everyone can forget to fill fuel in a fuel tank or to leave for the night included lighting devices.

And, at last, always it is necessary to try to make an accurate picture of development of malfunction and to undertake corresponding steps on relapse prevention. If refusal of an electric equipment was the result of infringement of quality of contact, check up at the same time a condition of all other contacts and electric sockets of system. If the same safety lock has fused some times successively, there is no sense in its further replacement - try to find out a cause of a failure. Remember that failure of a minor component can be a sign of infringement of functioning of more important knot or the whole system.

Automatic transmission (АТ)

In view of complexity of design АТ diagnostics of its malfunctions and repair of components is desirable for spending in a car-care centre workshop.

The shared problems connected with functioning of the mechanism of switching

    It is possible to carry the following to number of the refusals connected with infringement of adjustment of draught of switching:
      Engine start is possible at the positions of transmission which are distinct from “Р” and “N”; Indications of the indicator of position of transmission differ from really chosen transfer; The car moves at the transmission established in position “Р” or “N”; Transfers are switched hardly or any way.
    Make adjustment of draught of a gear change.

Transmission revolves, is switched hardly, publishes extraneous noise or does not provide car movement at installation on one of transfers

    There is a set of the possible reasons of the problems listed in heading, however under the competence of the mechanic-fan one of them - wrong level трансмиссионной liquids (ATF) gets only. Before driving away the car in a car-care centre workshop check up level and condition ATF. Modify level ATF or replace it.

Leaks трансмиссионной liquids (ATF) take place

    ATF has dark red colour. Traces of its leaks should not be confused to traces of impellent oil which can be taken down on картер transmissions by a running stream of air. For revealing and localisation of a source of leak first of all remove from a transmission boat all traces of a dirt and greasing. Take advantage approaching обезжиривателем and-or make steam cleaning. Then make on the car a short trip on small speed (that leak traces did not communicate a running stream far from its source). Stop, поддомкратьте the car and by visual survey establish a leak source. More often as those act:

Scratch of brakes

    Often reason in atmospheric influence (humidity of air). If the scratch appears after long parking at the raised humidity and then vanishes, anything it is not necessary to do. Are established колодки inappropriate type. The brake disk rotates not in parallel a support. The support mine is polluted. Погнуты fastening springs колодок. Press springs are stretched.

Pulsation of a pedal of a brake

    Sign of normal operation ABS. Palpation of a brake disk is excessively great. The brake disk rotates not in parallel a support.

Control lamp ABS lights up during movement

    Pressure of a food (more low 10) does not suffice. Check up pressure. Check up, whether the control lamp of the generator after engine start dies away. If everything is all right, check up a belt of a drive of the generator. Malfunction ABS takes place, - check up a condition and reliability of fixing клеммного connections of weight of the returnable pump (in the hydromodulator).

Suspension bracket and steering

The car withdraws at movement in one of the parties

    Tyres are pumped non-uniformly up. Defect of tyres takes place. Suspension bracket or steering components are worn excessively out. Carrying out of adjustment of corners of installation of forward wheels is required. Forward brake mechanisms are taken.

Jerks, дёрганье or vibrations take place
