Repair and operation of the car

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 memory, when there is appealing a scintillation of a lamp of control of ABS in a policeman of instrument of the car. The codes distinction begins with a pause that lasts 3,6 seconds. Then the sequence of impulses of the first one of written in the memory of processor of a code happens (series of blinkings of the main code, then, after a second pause, – series of blinkings of an additional code [if this it is supplied]). Besides, after a pause of five seconds, combination of codes (the principal and additional one) the second bad functioning, etc. stands out. The system allows to read aloud any quantity of codes. When someone wrote only information, companion compares it with the card of codes given on the table.

Code of bad functioning	Possible fountain of bad functioning
11	The sensor of the speed of the rotation of the right dispatches the wheel (circuit of interval / short circuit in a chain)
12	The sensor of the speed of the rotation of the right dispatches the wheel (electric hindrances or violation of the stability of the developed signs)
13	The sensor of speed of rotation of the left advanced wheel (circuit of interval / short circuit in a chain)
14	The sensor of speed of rotation of the left advanced wheel (electric hindrances or violation of stability of the developed signs)
15	The sensor of speed of rotation of right behind goes round (circuit of interval / short circuit in a chain)
16	The sensor of speed of rotation of right behind goes round (electric hindrances or violation of stability of the developed signs)
17	The sensor of speed of rotation of the left rear wheel (circuit of interval / short circuit in a chain)
18	The sensor of speed of rotation of the left rear wheel (electric hindrances or violation of stability of the developed signs)
21	The rotor of the sensor of the speed of the rotation of the right dispatches the wheel
22	Rotor of the sensor of speed of rotation of the left advanced wheel
23	Rotor of the sensor of speed of rotation of right behind goes round
24	Rotor of the sensor of speed of rotation of the left rear wheel
31	The entry the roll eletromagnético of the sensor of the right dispatches the wheel
32	The production the roll eletromagnético of the sensor of the right dispatches the wheel
33	When I entered I I roll eletromagnético of the sensor of the left advanced wheel
34	I roll production eletromagnético of the sensor of the left advanced wheel
35	When I entered I I roll eletromagnético of the sensor of right behind it goes round
36	I roll production eletromagnético of the sensor of right behind goes round

38	I roll production eletromagnético of the sensor of the left rear wheel
41	The blockade of the right dispatches the wheel
42	Blockade of the left advanced wheel
43	Blockade of right behind goes round
44	Blockade of the left rear wheel
51	Blockade of the motor
52	The motor is not lit
53	The motor is not put out
54	The security alternation is defective
61	Excessively low tension in a chain of ignition
62	Excessively high voltage in a chain of ignition

Besides, after a pause of five seconds, combination of codes (the principal and additional one) the second bad functioning, etc. stands out. The system allows to read aloud up to three codes. 2. If it lost the count reading codes, put the ignition out, then again they include it and begin again. One does not forget of from what any repair of ABS has to be made by specialists of the service of the car. The card of codes of bad functioning of ABS of the models of Full text for 1997 to question.

Cleaning of the memory of processor of ABS

After the elimination purified the system to processor memory it has to be compensated.

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

ORDER OF REALIZATION

1. To clean of the processor memory they withdraw a point of passage of wire of captures of the diagnostic capture, then not less than during three seconds they take the lock of security guard ABS B2 in 15 one of the car of the block of meeting installed in a compartment of reason. The insertion at the place a security lock and there adheres the capture of the diagnostic capture to a covering.

The models Integra for 1997 to question.

ORDER OF REALIZATION

1. Without withdrawing a point of passage of wire, put the ignition out, soon squeeze out a pedal of a foot they brake and again they turn the key of ignition in the position of in. When the lamp of control of ABS in an instrument policeman goes out, launch a pedal – the lamp has to be joined again. Again hold tight out a pedal and hope for the stoppage of a lamp. Launch a pedal. 2. The control lamp will blink two times, confirm memory of processor that the cleaning then is possible of putting the ignition out, withdrawing a point of passage of wire and restoring the initial connection of the diagnostic capture.
