Repair and operation of the car

Diagnostic of bad functioning

The description of the diagnostic one of systems of electronic control and the codes of bad functioning are supplied in the Chief Sistemy of the electric equipment of the motor.

In this section o scheme more simple of the clarification of the reasons of the bad functioning and refusals that happen in knots and systems of the car presents itself. The refusals and his possible reasons are broken in groups in a sign of the relation to certain component ones or the systems of the car, like the motor, the cooling system, etc., besides, in the references the text for chapters and sections about these problems happens.

Be remembered of what the quite succeeded realization of the inquiry of causes of the defect if it defines for the entirety of a complex of good knowledge and patient, systematic approximation of an inquiry of problem. It is necessary always to move from the simple one to a difficult one, to bring each check to the logical end and to try not to pass the obvious facts - everyone can forget of filling the fuel in the fuel tank or leaving included in the lighting of fixations of the night.

And, finally, it is always necessary to try to do a clear picture of the development of the bad functioning and to take the corresponding measures of the prevention of a repetition. If the failure of the electric equipment happened for a cause of the breach of the quality of the contact, check a condition of any other contacts and the electric captures of the system at the same time. If the same security lock merged several times successively, it has not been feeling in his new substitution - they try to discover a cause of the failure. Remember that the failure of a component juvenile can be a sign of the violation of the functioning of the most important knot or the whole system.

Motor

The essential conditions of the launch of any motor of gasoline are the usefulness of the provision of the mixture of air fuel in cylinders and opportune sparkling in spark captures.

First of all it is necessary to be secured of the usefulness of the provision of the fuel.

To define if the spark is formed, result when they were taken of spark, insert them in hints and separately apply to the weight. At the same time it is not necessary to maintain a wire or a tip hands, - they use the pliers of isolated flat nose. Ask a spectator to begin the motor. If the spark if it is going away, tries to define a cause of the failure.

The motor had not had been seen in attempts of his departure

Author

Contact with captures of an electrical system they have to concentrate confiantemente and do not rust!

• If the author does not turn, in the beginning it is necessary to secure that in the capture n ° 50 of the alternation of traction there is tension (at least 10 V). In negative results they check a condition of an electrical system of an outline of the current of an author.
• Since the check of the usefulness of the operation of an author in a tension full of the battery executes the next operations:
• Not including transfers, become a key in the provision of "in";
• ^{The author of Peremknite covers 30 and 50 encloses with a section not less than 4 mm2.}
• If the author works perfectly, the cause of the defect must be looked in wires to an author. If the author does not win, it must happen in the retired state.

The author does not revolve becoming a key in the "BROKEN" situation

1. The battery is unloaded.
2. The author of Peremknite covers 30 and 50: if the author revolves, 50 brought ones check the wire to the lock of ignition of the interval, also appreciate a condition of author's switch.
3. The weight wire is pulled out, or the quality of his terminal connection is broken.
4. Current weakening due to quality violation or oxidation of connections of contact.
