Anti-blocking system (ABS)

Depending on model and execution of MAZDA 323 it can be equipped with anti-blocking system (ABS). The additional ABS installation is impossible. The anti-blocking system prevents blocking of wheels at sharp braking. Thus, the car at complete braking remains operated. By means of the 4th sensors of speed speed of each wheel is measured. On the basis of signals of separate sensors of speed the electronic device calculates average speed which approximately corresponds to speed of the car. Comparing speed of a separate wheel to average speed of all wheels a monitor defines a condition of a probuksovyvaniye of a wheel and can establish the moment when the wheel is close to blocking.

If the wheel is inclined to blocking, i.e. pressure of brake liquid in the corresponding support too highly in relation to force of adhesion of a wheel from darling the hydraulic system on the basis of a signal from a monitor keeps pressure of liquid to constants. It means that pressure does not increase any more, despite pedal pressing. If there is a blocking threat further, brake pressure decreases opening of the final valve until the wheel will not start over again to be accelerated, then pressure is again supported to constants. Back wheels cope together, pressure in system decides by a back wheel on the greatest pro-slipping.

If the wheel is dispersed quicker than a certain value, pressure in system again raises, however, no more general pressure of all system.

This process for each wheel repeats until the gas pedal will be released, or the car will not be in a condition close to a stop (2-3 km/h).

The protective system provides automatic shutdown of ABS at an exit it out of operation (for example, because of cable break) or at too low voltage (tension of the battery is lower 10,5 In). In this case during movement the control lamp of ABS lights up. The usual brake system will function. The car when braking behaves how if it had no ABS. If during movement the control lamp of ABS lights up, it means that the anti-blocking system is disconnected.

 PERFORMANCE ORDER

  1. To stop the car, to muffle and again to start the engine.
  2. To check tension of the battery. If tension is lower 10,5 In, to charge the battery.

If at the beginning of a trip the control lamp of ABS burned, and after a while again went out, it means that in the beginning tension of the battery was too low, and then increased thanks to a charging from the generator.

  1. To check, that plugs of the battery were reliably tightened and had faultless contact.
  2. To lift the car, to remove forward wheels, to check electric wires of sensors of speed on existence of external damages.
  3. Further check of ABS should be made in a workshop. The monitor registers being shown malfunctions and writes down them in memory. In masterful MAZDAS it is possible to consider the written-down malfunctions from memory via the diagnostic tip.

Before electrowelding works it is necessary to disconnect the tip from a monitor. To disconnect the tip only at the switched-off ignition.
