Diagnostics of malfunctions
Diagnostics of malfunctions
The description of diagnostics of electronic control systems and diagnostic codes are provided in Head of the Power supply system, management of engine/decrease in toxicity of the fulfilled gases and production of the fulfilled gases (engine), and also in Heads Automatic transmission, Brake system and Onboard electric equipment
(AT, ABS/EBD, SRS and an immobilizer).
In this section the simplest scheme of clarification 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, such as the engine, cooling system, etc., besides, in the text references to chapters and sections concerning these problems are given.
Remember that the successful conclusion of search of causes of defect is defined by a combination of a certain knowledge and a patient, systematic 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 the corresponding steps on recurrence prevention. If refusal of electric equipment was the result of violation of quality of contact, check at the same time a condition of all other contacts and electric sockets of system. If the same safety lock several times in a row continues to fuse, there is no sense in its further replacement - it is necessary to try to find out a cause of failure. Remember that failure of a minor component can be a sign of violation of functioning of more important knot or the whole system.
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 lack of signs of violation of integrity of isolation, oxidation and weakening of fastening of contact connections. Check, 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 laying, serviceability of a condition and reliability of fastening of vacuum hoses, - in case of need address to data of information label of VECI (see in the Section Identification numbers and information labels). Do not forget to check also on existence of signs of development of leaks components of an inlet air path.
Mechanical checks
If during visual survey of any obvious violations it is not possible to reveal, it is necessary to make check of kompressionny pressure in engine cylinders. The description of check is provided in the Section Check of kompressionny pressure, an assessment 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 manometer, or the vacuum gage. In the first case it is necessary to turn out warmed up a lambda probe, or the control valve of system of a podmeshivaniye of air in an exhaust (depending on a complete set). Screw to the place of the removed component a manometer with a range of measurement of 0 ? 0.35 kgfs/cm2 and start the engine with turns 2500 in a minute, - if the antipressure size in a final path makes more than 0.14 kgfs/cm2, passableness violation, - most likely the catalytic converter therefore takes place. When using the vacuum gage connect it to the vacuum union of the inlet pipeline, start the engine and consider the measuring instrument indication. Partially slightly open and fix a butterfly valve, - slow falling of depth of depression after stabilization of turns will testify also to violation of passableness of a final path.
Checks of serviceability of supply of fuel
At this stage of base diagnostics it is necessary to make the following checks (see. Power supply systems, managements of engine/decrease in toxicity of the fulfilled gases and production of the fulfilled gases):
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;
Assessment 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 of an iskroobrazovaniye on spark plugs, - check is best of all for making by means of a special tester. At identification of violations measure specific resistance of VV of electroconducting, - the result of measurement should not exceed value of 16 kiloohms/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. Head of System of electric equipment of the engine).
