System of anti-blocking of brakes (ABS) - the general information and codes of malfunctions When the vehicle is equipped with brake system of usual type, sharp squeezing of a pedal of a foot brake leads to blocking of wheels. Thus coupling of a protector with a paving is broken, and the car can start to skid, losing controllability. The system of anti-blocking of brakes (ABS) prevents premature blocking of wheels, continuously operating the speed of their rotation during braking due to modulations of pressure of hydraulic liquid in each of brake mechanisms.ABS consists of two main subsystems: electric and hydraulic. The electric part of system includes four sensors of speed of rotation of wheels, the processor of management and a set of a connecting electrical wiring. The hydraulic part includes pressure modulator, supports of disk brake mechanisms and hydraulic lines connecting components. The principle of functioning of system is rather simple. Each of wheels is equipped with the individual sensor of turns. The sensor consists of a rotor (a ring with the teeth which are evenly located on its perimeter) and a sensitive element in the form of the podmagnichenny coil. The sensitive element of the sensor fixes the moments of passing of rotor teeths by it and will transform the received information to electric signals, the control of ABS which are continuously transferred on the processor. By results of processing of the arriving signals the processor receives information on the relative speed of rotation of each of wheels. While all four wheels rotate with an identical frequency, ABS stays in a passive state. As soon as any of wheels starts being blocked, the processor fixes change of the entering signal and develops command for operation of the modulator which is instantly dumping pressure of hydraulic liquid in the brake mechanism of the corresponding wheel. As soon as normal rotation of a wheel is restored, the processor stops functioning of the modulator. Actually the scheme of functioning of ABS is much more difficult, than it can seem therefore authors of the present manual do not recommend to owners of cars to make attempt of independent performance of repair of system. In case of malfunctions it will be most reasonable to address to specialists of car service. Reading of codes of malfunctions of ABS At start of the engine the control lamp of ABS on an instrument guard of the car has to join quickly and almost at once again go out. If because of any violation the lamp remains the included ambassador of implementation of start of the engine, the ABS processor writes down the corresponding digital code in memory of the block of self-diagnostics. Reading of codes is made by means of the special scanner connected to the 16-contact diagnostic socket located under a forward overlay of a threshold of a driver's door of the car. In lack near at hand of the scanner the car should be driven away for reading of memory and performance of necessary recovery repair on car repair shop.The ID card of codes of malfunctions of ABS is given below.
Cleaning of memory of the ABS processor After elimination debugged system memory of the processor it has to be cleared. Memory cleaning again requires the scanner in the absence of which near at hand the car should be driven away on car repair shop. More detailed information on the skanerny reader is provided in the Head Engine management. |
