Diagnostics of malfunctions of knots and systems of the car

The owners of cars performing procedures of routine maintenance of the vehicle it agrees provided in the Head Nastroyki and routine maintenance of the present manual of the schedule will be extremely seldom forced to address materials of this Section. Reliability of the knots and components installed on modern cars is so high that at timely performance of replacement of the materials of details which are worn out and failed as a result of aging the probability of their sudden refusal is extremely small. Refusals seldom happen spontaneously and usually are a consequence sometimes of long development of defect. In particular, failure of mechanical components practically is always preceded by emergence and development of the characteristic symptoms which are shown sometimes for many thousands of kilometers of a run to the full. The same components which can fail unexpectedly usually are not vital for functioning of the main knots and systems of the car, 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 is lying on a surface, however in certain cases it is necessary to work, making small investigation. The motorist who produced half-dozens of casual checks of replacements and corrections quite has chance to find a cause of failure (or its symptom), however it is impossible to call such approach reasonable, in view of its labor input and aimlessness of expenses of time and means in any way. There is a quiet logical approach to search of the failed knot or component much more effectively. Surely it is necessary to take into account everything preceding breakage, sometimes insignificant, symptoms and the guarding signals, such as loss of the power 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 of the hidden violation.

In this subsection rather simple scheme of diagnostics of the most often found refusals is given below. 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 Sections of the Management concerning functioning of the components suspected of malfunction are given.
Regardless of the refusal nature investigations of its reason are always taken the identical basic principles as a principle:

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

Try not to miss obvious violations. For example, if the engine is not started, do not hesitate to check availability of fuel in a gasoline tank (at the same time it is not necessary to take on trust statements of the owner of the faulty car). In case of refusal electric equipments first of all it is necessary to check a state and reliability of fastening of terminal connections of an electrical wiring, only after it it makes sense to get diagnostic units.

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

Do not take on trust any statements. Remember that the "new" component can also be 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 this recommendation when the cause of failure established, at last, is lying on a surface from the very beginning.

Diagnostics of malfunctions of AT

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

Leakages of ATF

1. ATF usually differs in dark red color. It is not necessary to confuse traces of its leaks to those from motive oil, - the last can communicate on a transmission case the running air stream.
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 lubricant. Use qualitative degreaser or execute steam cleaning of the unit. Make on the car a short trip with a low speed of the movement (that traces of the leak taking place did not communicate far from its source). The car also establish to Poddomkratta it on props. Examine a transmission case, visually revealing leakage sources of ATF. Most often act as those:

- The transmission case pallet (see Chapters of Control and routine maintenance and the Transmission);
- The directing tube of the measuring probe (see Chapters of Control and routine maintenance and the Transmission);
- Lines of an oil path of transmission (see the Head the Transmission);
- The speed sensor (see the Head the Transmission).
- Epiploons of power shafts (see the Head the Transmission).

ATF has brown color or smells of ashes

The ATF level fell in transmission, or liquid burned and needs replacement (see the Head Nastroyki and routine maintenance).

Problems with gear shifting take place

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

- The engine is started in situation, excellent from "Р" or "N";
- The provision of transmission highlighted on the display panel differs from actually chosen;
- The car is set in motion at the transmission established in situation "P";
2. The description of the procedure of adjustment of the driving mechanism of the selector is provided also in the Head the Transmission.

There is no automatic switching of transmission to a low gear at full squeezing of the accelerator pedal

AT has the electronic control and any problems connected with violation of functioning of components of management have to decide by forces of specialists of car service.

The engine is started in the provision of transmission, excellent from "Р" or "N"

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

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

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