Anti-lock braking system ABS — general description

The anti-lock braking system ABS consists of wheel speed sensors, a brake light switch, a hydraulic unit and an electronic control unit (ABS-ECU). If a malfunction occurs in the system, the faulty unit can be found through diagnostics. Using the MUT-II diagnostic tool, you can read diagnostic codes and technical data, as well as check actuators. The diagram of the anti-blocking system ABS of cars with left-hand drive is shown in fig. 14.34a, a diagram of the anti-lock braking system ABS of cars with right-hand drive - in fig. 14.34b. The technical characteristics of the anti-lock braking system ABS are given in table 14.3. The technical data of the anti-lock braking system ABS are given in table 14.4. Codes of diagnostics of antiblocking system ABS are resulted in table 14.5.
