Diagnostics of malfunctions of knots and car systems

The owners of cars who are carrying out procedures of routine maintenance of the car Routine maintenance of the present Management to the schedule agrees resulted in the Head will be extremely seldom compelled to address to materials of the given section. Reliability of knots and the components established on modern cars is so high that at timely performance of replacement worn out and failed as a result of ageing of a material of details the probability of their sudden refusal is smallest. Refusals extremely seldom occur spontaneously and usually of defect development (sometimes long) are a consequence. In particular, refusal of mechanical components is preceded always by occurrence and development of the characteristic symptoms shown sometimes for many thousand of kilometres of run to an exit of faulty knot out of operation. The same components which can fail unexpectedly usually are not vital for functioning of the basic knots and car systems, or are easily replaced directly on the car in road conditions.

Basic step at revealing of the reason of any refusal is the choice of a point of the beginning of searches. Often the reason appears enough obvious, however in certain cases it is necessary to work, making small investigation. The motorist who has made half-dozen casual checks, replacements and corrections quite has to find out a cause of a failure (or its symptom), however such approach in any way it is impossible to consider chance reasonable, in view of its labour 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. Necessarily it is necessary to take into consideration all preceding breakage, sometimes insignificant, symptoms and guarding signals, such as loss of capacity developed by the engine, change of indications of measuring instruments, occurrence 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 of the more deeply latent infringement.

More low in the given section simple enough scheme of diagnostics of most often happening refusals is resulted. The reasons of infringements and their symptoms are grouped on the basis of their relation to functioning of any concrete unit or system, for example: the Engine, cooling System etc. In brackets are given references to corresponding Chapters and the sections of the Management concerning functioning of components suspected of malfunction.
Without dependence by nature refusal identical base principles are put in a basis of investigation of its reason:

- Make sure of correctness of definition of symptoms of refusal. This means confidence of delimitation of area of searches that is especially important with the help in refusal diagnostics to other motorist which not in a condition adequately to state symptoms of taking place infringement.

- Try not to look through obvious infringements. For example, if the engine is not started, do not hesitate to check up fuel presence in a petrol 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 up a condition and reliability of fastening клеммных electroconducting connections, only after that it makes sense to get diagnostic devices.

- Try to eliminate a cause of a 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 filled in with oil (petrol engines) will allow to restore for some time serviceability of functioning of the engine, however its refusal by all means soon will repeat again (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 itself can appear faulty, in particular, if it long time has lain 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 performance of the made recommendation, when the cause of a failure revealed at last will appear lying on a kind from the very beginning.

Diagnostics of malfunctions of automatic transmission

In view of complexity of design АТ to the average mechanic-fan will be inconveniently enough exact to carry out diagnostics of its refusals and regenerative repair. In case of occurrence of the problems which distinct from are listed more low, to the owner the car it is necessary to address for the help to experts of a workshop of car-care centre. It is not necessary to hasten also with демонтажем faulty transmission as its many checks are made in situ (on a regular place).

Leaks ATF

• ATF usually has dark colour. It is not necessary to confuse traces of its leak to those from impellent oil - the last can communicate on картер transmissions by a running stream of air.
• For revealing of a source of leak, first of all, it is necessary to clear картер transmissions and surfaces surrounding it of a dirt and greasing (take advantage qualitative обезжиривателем or execute steam cleaning of the unit). Make on the car a short trip with low speed of movement (that leak traces did not communicate far from its source). Поддомкратьте the car also establish it on props. Examine картер transmissions, visually revealing sources of leak ATF. Most often as those act:

- The pallet картера transmissions (Routine maintenance and section Automatic transmission see the Head)
- Directing tube measuring probeа (Routine maintenance and section Automatic transmission see the Head)
- Tubes of connection of transmission with cooler ATF and their unions (Automatic transmission see)

ATF has brown colour or smells as ashes

• level ATF in transmission Has fallen, or the liquid requires replacement (address to the Head Routine maintenance).

Shared problems with a choice of transfers take place

• In section Automatic transmission check and adjustment procedures drive a cable of the selector of transfers АТ are described. Shared problems which can appear connected with adjustment infringement drive a cable are more low listed most:
- The engine is started in the position which is distinct from “Р” or “N”;
- Position of transmission highlighted on the display panel differs from actually chosen;
- The car is set in motion at the transmission established in position “Р” or “N”;
- There are difficulties with a choice or a gear change.
• the Description of procedure of adjustment drive a cable of the mechanism of the selector is resulted in section Automatic transmission.
- There is no automatic switching of transmission on a hill-climbing gear (mode Kick-Down) at full squeezing of a pedal of gas.
• level ATF (address to the Head Routine maintenance) Has fallen.
• adjustment drive a cable of a choice of transfers (Automatic transmission see) Is broken.

• adjustment of the gauge-switch of the permission of start (Automatic transmission see) Is broken.
• adjustment drive a cable of a choice of transfers (Automatic transmission see) Is broken.

Transmission "comes off" the chosen position, 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 sphere of the competence of the average mechanic-fan - infringement of level ATF only. Check up, in case of need make updating of level/replacement of a liquid and the filter, in parallel check up condition ATF (address to the Head Routine maintenance). In all other cases the car should be driven away for diagnostics and regenerative repair/replacement of transmission in a car-care centre workshop.
