System of antiblockade of brakes (ABS) – the general information and codes of bad functioning

General information

When the vehicle is equipped of the system of brakes of the usual, sharp type to squeeze of a pedal of a brake of foot leads to the wheels blockade. At the same time the union of a protector with a road surface is broken, and the car can begin to slip, having lost controllability. The system of the antiblockade of brakes (ABS) juts out to prevent the premature blockade of wheels, when continuously working the speed of his rotation during the frenagem due to modulations of the pressure of hydraulic liquid in each one of mechanisms of brake.

ABS is composed of two main subsystems: electric and hydraulic. Four sensors of the speed of the rotation of wheels, the processor of management and group of an electrical system that is joined enter in an electric part of the system. A hydraulic part includes modulador of pressure, supports of mechanisms of brake of disc and hydraulic lines that adhere between component them.

The beginning of the functioning of the system is quite simple. Each one of wheels is equipped of the meter of REVOLUTIONS FOR individual MINUTE. The sensor is composed of a rotor (a ring with the teeth that are located exactly in his perimeter) and a sensitive element in the form of the roll of podmagnichenny. The sensitive element of the sensor fixes the moments of the passage of the rotor teeths for him and it will transform the information obtained the electric signs, control of ABS that are transferred continuously in the processor. For results of the processing of the signs they bring the processor near it obtains the information on the relative speed of the rotation of each one of wheels. While four wheels revolve with an identic frequency, ABS stays in a passive state. As soon as some of wheels begins to be blockaded, the processor fixes the modification of the sign of entry and develops the order of the operation of the modulador that deposits immediately the pressure of hydraulic liquid in the mechanism of brake of the corresponding wheel. As soon as the normal rotation of a wheel is restored, the processor stops working of the modulador.

In fact the scheme of the functioning of ABS is much more difficult, of what it can seem, therefore, that the authors of the present manual do not recommend to cars owners doing attempts of the realization independent of the repair of the system. In case of bad functioning the most reasonable thing will be to direct specialists of the service of the car.

Reading code of bad functioning of ABS

ORDER OF REALIZATION

1. In the launch of the motor the lamp of control of ABS in a policeman of instrument of the car has to be joined quickly and almost at the same time again to go out. If because of any violation the lamp will remain included after the implementation of the launch of the motor, the processor ABS writes the corresponding digital code in the memory of the block of the autodiagnostic one. To read of a code of a lamp of control:    a) Launch the capture of the diagnostic capture of the covering located below a box of article (to see the Head of the System of control of the motor);    b) One two contacts of the capture a point of passage of wire.

The Civic models (and It Integrates from 1998 of the question)

ORDER OF REALIZATION

1. Include the ignition (they do not begin the motor). Two seconds then after turning it of a key in the situation in the PROCESSOR ABS will begin to give the codes of bad functioning that are written in his
