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 a time of long development of defect. In particular, failure of mechanical components practically always is preceded by emergence and evolution 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. The quiet logic approach to search of the failed knot or a component appears much more effective. 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.

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.

First of all it is necessary to estimate the general mechanical condition of the power unit.

Functioning of a control system by supply of fuel on injector models is based on continuous monitoring of giving of the air and fuel mix, based on continuous data transmission from information sensors to the management module. Unlike carburetor models where for fuel pushing through through dosing-out jets for the purpose of providing demanded composition of gas mixture the energy developed by a stream of an air stream soaked up in the engine is used, on the models equipped with system of injection quality control of a mix it is carried out by means of management of duration of opening of injectors through which fuel moves in the pipeline / inlet ports of chambers of combustion.

Management is made on the basis of the analysis of the data which are continuously arriving from the corresponding information sensors. Sensors trace such parameters as working temperature of cooling liquid, temperature and amount of air soaked up in the engine, turns of a cranked shaft, the current provision of a butterfly valve, etc. the control unit continuously analyzes arriving information and defines duration of opening of injectors of injection demanded at the moment time. Sensors develop low-voltage signals in this connection violation of quality of contact connections of electroconducting of the corresponding connecting chains can make the most direct impact on efficiency of return of the engine (comparable with the influence rendered by an exit of sensors out of operation).

At the problem diagnostics, connected with serviceability of functioning of system of injection always first of all check a condition of the corresponding electroconducting of its contact connections. Watch reliability of fixing of electric sockets, periodically check their physical condition. Try not to use for cleaning of surfaces of components and control system electroconducting not approved by manufacturers of cars chemical means, - after application of such funds for surfaces of cleared components there can be a film which presence is inadmissible the risk of damage of isolation of electroconducting, besides, is great.

The system of electric equipment of the engine provides power supply giving to all onboard consumers, electronic control units, information sensors and actuation mechanisms. In view of extreme sensitivity of elements of a control system of the engine to tension differences, violation of serviceability of functioning of a generator/regulator of tension can lead to appreciable decrease in efficiency of return of the power unit. Cars considered in the real Management usually are completed with generators with the built-in regulator of tension. Working parameters of such regulators are not subject to adjustment and in case of violations it is necessary to replace the corresponding element (a regulator or the generator) assembled.

Functioning of system of ignition is also strongly connected with work of system of injection of fuel/engine management and is based on use by the module of management of data arriving from the corresponding information sensors. On the basis of the analysis of information arriving from sensors the module of management makes timely corrections of a corner of an advancing of ignition, achieving optimum operation of the engine at any turns and the current loadings. On the majority modern this sort of systems manual adjustment of a corner of an advancing of ignition any more is not represented possible. In case of violation of serviceability of functioning of such system the failed element is subject to replacement, - previously make sure that refusal is not connected with electroconducting damage, or weakening of fastening of its contact sockets. Periodically check a condition of electric sockets, in case of need process them with application of patent cleaners.

Councils on carrying out diagnostics of the problems connected by functioning of brake system

The reasons of emergence of pulsations and the vibrations appearing during braking usually come to light during trial runs of the car.

If vibrations arise in a brake pedal at its squeezing and are not transferred on steering a wheel, that, most likely the reason of their emergence is non-uniform wear or deformation of disks/drums of brake mechanisms of back wheels. Return in a wheel testifies to need of check first of all conditions of brake disks of forward wheels.

Pedal failures when braking can be connected with air hit to the hydraulic highway of system, or with boiling up of working liquid as a result "prikhvatyvaniye" of brake mechanisms or an incomplete otpuskaniye of the parking brake. The probability of violation of adjustment of drum-type brake mechanisms of back wheels is not excluded also. For check, without starting the engine, several times rock a brake pedal and, holding it squeezed out, cock the parking brake, then release a pedal and at once squeeze out it back. If at repeated squeezing the pedal "fails", therefore back brake mechanisms need adjustment.

It is not necessary to compensate violation of adjustment of drum-type brake mechanisms by fine tuning of the parking brake as it will result in premature wear of overlays of brake boots.
