Diagnostics of malfunctions

The description of diagnostics of electronic control systems and diagnostic codes are resulted in the Head of the Power supply system, management of the engine/decrease of toxicity of the fulfilled gases and release of the fulfilled gases (engine), and also in Heads Automatic transmission, Brake system and the Onboard electric equipment (АТ, ABS/EBD, SRS and an immobilizer).

In the given section the most simple scheme of finding-out of the reasons of malfunctions and the refusals occurring in knots and systems of a vehicle is offered. Refusals and their possible reasons are broken into groups on the basis of the relation to certain components or car systems, as for example the engine, cooling system, etc., besides, in the text references to chapters and sections concerning the given problems are given.

Remember that successful end of search of causes of defect is defined by a combination of certain knowledge and the patient, regular approach to problem research. To move always follows from simple to difficult, to lead up each check to the logic end and to try not to pass the obvious facts - everyone can forget to fill fuel in a fuel tank or to leave for the night included lighting devices.

And at last, always it is necessary to try to make an accurate picture of development of malfunction and to undertake corresponding steps on relapse prevention. If refusal of an electric equipment was the result of infringement of quality of contact, check up at the same time a condition of all other contacts and electric sockets of system. If the same safety lock some times continues to fuse successively, there is no sense in its further replacement - it is necessary to try to find out a cause of a failure. Remember that failure of a minor component can be a sign of infringement of functioning of more important knot or the whole system.

The engine

Base checks at the complicated start of the engine

If the engine is not started, it is necessary to try to analyse a situation coolly.

Petrol models

Visual survey

Estimate an external condition of all electroconducting in an impellent compartment, make sure of absence of signs of infringement of integrity of isolation, oxidation and easing of fastening of contact connections. Check up, whether is not present in the assembly block of the beaten out safety locks, whether will burst the case of the storage battery. Further it is necessary to make sure of correctness of a lining, serviceability of a condition and reliability of fastening of vacuum hoses, - in case of need address to the data of information label VECI (Identification numbers and information labels see in Section). Do not forget to check up also on presence of signs of development of leaks components of an inlet air path.

Mechanical checks

If during visual survey it is not possible to reveal any obvious infringements, it is necessary to make check компрессионного pressure in engine cylinders. The check description is resulted in Section Check компрессионного pressure, an estimation of a condition of cylinders.

One more important among mechanical check is check of passableness of a final path of the engine. Check can be made by means of a manometre, or the vacuum gauge. In the first case it is necessary to turn out a warmed up ljambda-probe, or the control valve of system подмешивания air in an exhaust (depending on a complete set). Screw to the place of the removed component a manometre with a range of measurement 0 0.35 кГс/см2 and start the engine with turns 2500 in a minute, - if the size противодавления in a final path makes more than 0.14 кГс/см2, passableness infringement, - most likely каталитического the converter hence takes place. At vacuum gauge use connect it to the vacuum union of the inlet pipeline, start the engine and consider the measuring instrument indication. Partially slightly open and fix throttle заслонку, - slow falling of depth of depression after stabilisation of turns will testify also to infringement of passableness of a final path.

Checks of serviceability of giving of fuel

Before the performance beginning большей from listed below checks it is necessary for part to make сбрасывание pressure in the power supply system, - the procedure description is resulted in the Head of the Power supply system, management of the engine/decrease of toxicity of the fulfilled gases and release of the fulfilled gases. Before start of the engine after pressure dump in the power supply system it is necessary to execute preliminary filling of its path, - such filling will allow to reduce essentially duration necessary проворачивания the engine a starter. The procedure description is resulted also in the Head of the Power supply system, management of the engine/decrease of toxicity of the fulfilled gases and release of the fulfilled gases.

At the given stage of base diagnostics it is necessary to make following checks (Power supply systems, managements of the engine/decrease of toxicity of the fulfilled gases and release of the fulfilled gases see):

  • Check of adjustable pressure of fuel;
  • Pressure check in fuel lines;
  • Check of tightness of components of a fuel path;
  • Check of a condition of the relay of the fuel pump;
  • Estimation of a condition of fuel injectors.

Checks of serviceability of functioning of system of ignition

First of all it is necessary to make sure of serviceability искрообразования on spark plugs, - check is better to make by means of a special tester. At revealing of infringements measure specific resistance ВВ of electroconducting, - the result of measurement should not exceed value 16 clod/m.

Further it is necessary to make check of serviceability of giving of a food on the coil of ignition and to measure resistance of primary and secondary contours of the coil (see the Head of System of an electric equipment of the engine).
