Diagnostics of malfunctions

In this Section the simplest scheme of clarification of the reasons of malfunctions and the refusals occurring in knots and systems of a vehicle 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 are given references to Chapters and the Sections concerning these problems.

Remember that the successful conclusion of search of causes of defect at all is not the black magic available to only skilled professional mechanics, and is defined by a combination of a certain knowledge and a patient, systematic 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 the corresponding steps on recurrence prevention. If refusal of electric equipment was the result of violation of quality of contact, check at the same time a condition of all other contacts and electric sockets of system. If the same safety lock several times in a row continues to fuse, there is no sense in its further replacement - it is necessary to try to find out a cause of failure. Remember that failure of a minor component can be a sign of violation of functioning of more important knot or the whole system.

Automatic transmission (AT)

In view of complexity of a design of AT complete diagnostics of its malfunctions and repair of components are inaccessible to qualification of the average amateur mechanic. At emergence of any, excellent from listed below problems of functioning of AT the car should be driven away for check and repair in a workshop of car-care center or dealer office of the company.

The common problems connected with functioning of the mechanism of switching

  1. It is possible to carry the following to number of the refusals connected with violation of adjustment of draft of switching:
    • Start of the engine is possible at provisions of transmission, distinct from "P" (Parking) and "N" (Neutral).
    • Indications of the indicator of provision of transmission differ from really chosen transfer.
    • The car moves at the transmission established in the situation "P".

There is a set of the possible reasons of the problems listed in heading, however under competence of the amateur mechanic one of them - the wrong level of transmission liquid gets only.

Before driving away the car in a workshop of car-care center check level and a condition of transmission liquid (Head Automatic transmission). Modify level according to requirements of Specifications or replace liquid together with the filter. If the situation was not corrected, address for the help to experts.

Leakages of transmission liquid take place

  1. AT liquid has dark red color. Traces of its leaks should not be confused to traces of impellent oil which can be demolished on a case of transmission by a running stream of air.
  2. For identification and localization of a source of leak first of all remove from a transmission boat all traces of dirt and greasing. Use a suitable obezzhirivatel and/or make steam cleaning. Then make on the car a short trip on small speed (that traces of leak 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:
    • Pallet of a case of transmission: Tighten fixing bolts and/or replace pallet laying.
    • Tube of the gulf of liquid: Replace rubber consolidation in a place of an entrance of a tube in a transmission case.
    • Lines of transmission liquid: Tighten shtutserny connections or replace lines.
