Diagnostics of malfunctions of knots and car systems

The owners of cars who are carrying out procedures of routine maintenance of a vehicle it agrees given in Head of Control and routine maintenance of the real Management of the schedule will be extremely seldom compelled to address to materials of this Section. Reliability of knots and the components established on modern cars is so high that at timely performance of replacement of the materials of details worn out and failed as a result of aging the probability of their sudden refusal is smallest. Refusals seldom occur spontaneously and usually are a consequence sometimes of long development of defect. In particular, failure of mechanical components practically always is preceded by emergence and development of the characteristic symptoms which are showing sometimes for many thousand kilometers of run to the full. The same components which can fail unexpectedly, usually are not vital for functioning of the main knots and car systems, or are easily replaced in road conditions.

Fundamental step at identification of the reasons of any refusal is the choice of a point of the beginning of searches. Often the reason appears lying on a surface, however in certain cases it is necessary to work, making small investigation. The motorist who has made half-dozens of casual checks, replacements and corrections quite has chance to find a cause of failure (or its symptom), however in any way it is impossible to call such approach reasonable, in view of its labor input and aimlessness of expenses of time and means. There is a quiet logic approach to search of the failed knot or a component much more effectively. Surely it is necessary to take into consideration everything preceding breakage, sometimes insignificant, symptoms and guarding signals, such as loss of capacity developed by the engine, change of indications of measuring instruments, emergence of unusual sounds and smells, etc. Do not forget that failure of such components as safety locks or spark plugs can be only a symptom more deeply the hidden violation.

Below rather simple scheme of diagnostics of most often meeting refusals is provided in this subsection. The reasons of violations and their symptoms are grouped in a sign of the relation to functioning of any concrete unit or system: "Engine", “Cooling system” etc. In brackets references to the corresponding Chapters and the Sections of the Management concerning functioning of components suspected of malfunction are given.
Regardless of the refusal nature in a basis of investigation of its reason identical base principles are always put:

Make sure of correctness of definition of symptoms of refusal. Told means confidence of delimitation of the area of searches that is especially important with the help in refusal diagnostics to other motorist who cannot adequately state symptoms of taking place violation.

Try not to look through obvious violations. For example, if the engine is not started, do not hesitate to check availability of fuel in a fuel tank (thus it is not necessary to take on trust statements of the owner of the faulty car). In default electric equipments first of all it is necessary to check a condition and reliability of fastening of terminal connections of electroconducting, after it it is meaningful to get diagnostic devices.

Try to eliminate a cause of failure, instead of its symptom. Replacement of the discharged battery new will help to make the engine start, however the taking place reason of a discharge of the old battery remains not eliminated that will lead to fast failure and new. Also replacement of the spark plugs thrown by oil will allow to restore for some time serviceability of functioning of the engine, however refusal by all means will soon repeat (if the reason lay not simply in application of candles not that type).

Do not take on trust any statements. Remember that the "new" component also can appear faulty, in particular if it long time lay in a luggage carrier - it is not necessary to exclude a component from the list checked only for the reason that it is new or is recently established. In case of neglect it is not necessary to be surprised with implementation of the made recommendation, when the cause of failure revealed, at last, will appear lying on a surface from the very beginning.

Diagnostics of malfunctions of AT

In view of complexity of a design of AT to the average amateur mechanic will be inconveniently enough exact to carry out diagnostics of its refusals and regenerative repair. In case of problems, excellent from listed below, the owner of the car should address for the help to specialists of car-care center. It is not necessary to hurry also with demontazhy faulty transmission as its many checks are made by in situ (on a regular place).

Leakages of ATF

1. ATF usually differs dark red color. It is not necessary to confuse traces of its leaks to those from impellent oil, - the last can communicate on a case of transmission by a running stream of air.
2. For identification of a source of leak, first of all, it is necessary to clear a case of transmission and surfaces surrounding it of dirt and greasing. Use a qualitative obezzhirivatel or execute steam cleaning of the unit. Make on the car a short trip with low speed of movement (that traces of taking place leak did not communicate far from its source). To Poddomkratta the car also establish it on props. Examine a transmission case, visually revealing sources of leakage of ATF. Most often as those act:

- The pallet of a case of transmission (see. Heads of Control both routine maintenance and Transmission);
- A directing tube measuring щупа (see. Heads of Control both routine maintenance and Transmission);
- Lines of an oil path of transmission (see. Head Transmission);
- The sensor of speed (see. Head Transmission).
- Epiploons of power shafts (see. Head Transmission).

ATF has brown color or smells as ashes

ATF level fell in transmission, or liquid burned and needs replacement (see. Head of Control and routine maintenance).

Problems with gear shifting take place

1. In Head the Transmission procedures of check and adjustment of a drive of the selector of transfers of AT are described. Most common problems which can appear connected with violation of adjustment of a drive below are listed:

- The engine is started in situation, distinct from "R" or “N”;
- The provision of transmission highlighted on the display panel differs from the actually chosen;
- The car is actuated at the transmission established in the situation "R";
2. The description of procedure of adjustment of the driving mechanism of the selector is provided also in Head the Transmission.

There is no automatic switching of transmission on a low gear at complete squeezing of a pedal of gas

AT has electronic control and any problems connected with violation of functioning of components of management should decide strengths of specialists of car-care center.

The engine is started in the provision of transmission, distinct from "R" or “N”

The sensor switch of permission of start is faulty, or its adjustment (is broken see. Head Transmission).

Transmission "comes off" the chosen situation, is switched hardly or with noise, or does not provide car progress forward or back

There is a set of the possible reasons of the listed refusals, however one of them gets to the sphere of competence of the average amateur mechanic - violation of level of ATF only. Check, in case of need make adjustment liquid and filter level/replacement, in parallel check ATF condition (see. Head of Control and routine maintenance). In all other cases the car should be driven away for diagnostics and regenerative repairs/replacements of transmission by car repair shop.
