Diagnostics of malfunctions

In this Section the simplest scheme of clarification of the reasons of the malfunctions and refusals happening in knots and systems of the vehicle is offered. Refusals and their possible reasons are broken into groups on a sign of the relation to certain components or systems of the car as, for example the engine, the cooling system, etc., besides, in the text are given references to Chapters and Sections concerning these problems.

Remember that the successful completion of search of causes of defect is not the black magic available only to skilled professional mechanics at all, and is defined by a combination of a certain knowledge and patient, systematic approach to a problem research. It is necessary to move always from simple to difficult, to bring each check to the logical end and to try not to pass the obvious facts - everyone can forget to fill fuel in the fuel tank or to leave included in lighting fixtures for the night.

And, at last, it is always necessary to try to make a clear picture of development of malfunction and to take the corresponding steps for prevention of a recurrence. If the failure of electric equipment happened for a cause of infringement of quality of contact, check a condition of all other contacts and electric sockets of system at the same time. 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 full diagnostics of its malfunctions and repair of components are inaccessible to qualification of the average amateur mechanic. At emergence of any, other than the listed below problems of functioning of AT the car should be driven away for check and repair in a workshop of car service 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 the provisions of transmission other than "P" (Parking) and "N" (Neutral).

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

Before driving away the car in a workshop of car service check the level and a condition of transmission liquid (The head Automatic transmission). Modify level according to requirements of Specifications or replace liquid together with the filter. If the situation did not improve, ask for the help experts.

Leak of transmission liquid takes place

  2. For identification and localization of a source of leak first of all remove all traces of dirt and lubricant from the transmission boat. Use suitable degreaser and/or make steam cleaning. Then make on the car a short trip at a small speed (that traces of leak did not communicate the running stream far from its source). Stop, the car and by visual survey establish to a poddomkratta a leak source. Most often act as those:
    • Transmission case pallet: Tighten fixing bolts and/or replace laying of the pallet.
    • Tube of the gulf of liquid: Replace rubber consolidation in the place of an entrance of a tube to a transmission case.
    • Lines of transmission liquid: Tighten nipple connections or replace lines.

  2. Excessively the level of hydraulic liquid fell (The head Podvesk and steering).
  3. Passability of hoses or lines of hydraulic system is broken. Check, in case of need make replacements.
  4. Air got to hydraulic system. Pump over system (The head Podvesk and steering).

Excessive wear of protectors takes place (not in one some area)

  1. Tires are pumped incorrectly up.
  2. Balancing of wheels is broken. Address in a tire workshop
  3. Disks of wheels are damaged. Check, in case of need make replacement.
  4. Components of a suspension bracket or steering are excessively worn-out (The head Podvesk and steering).

Excessive wear of protectors on an outer edge takes place

  1. Tires are pumped incorrectly up.
  2. Turns are too sharply made. Reduce speed.
  3. Adjustment of angles of installation of forward wheels (excessive convergence) is broken. Address in a workshop for carrying out professional adjustment.
  4. The suspension bracket lever is bent or twisted (The head Podvesk and steering).

Excessive wear of protectors on an inner edge takes place

  1. Tires are pumped incorrectly up.
  2. Adjustment of angles of installation of forward wheels is broken (divergence). Make adjustment in a workshop of car service.
  3. Components of steering are damaged or their fastening weakened (The head Podvesk and steering).

Local wear of a protector takes place

  1. Balancing of wheels is broken.
  2. Disks are damaged or bent. Check, in case of need make replacement.
  3. Defect of tires takes place.
