The ABS system is one of the most important in any vehicle. However, due to its prevalence, drivers sometimes forget to check it. And this must be done, especially if the car is used. In the event of a breakdown, the helmsman gets into serious trouble. The AvtoVzglyad portal tells about the main dangers.
Looking at the time of purchase of a used car, we must not forget that the seller can hide ABS malfunctions. This is done with a scanner. Errors are cleared and when the car changes hands, the “style” reappears. Therefore, mandatory diagnostics are necessary, because if the system unit has to be changed, it will hurt the citizen’s wallet. Yes, repairs are cheap.
Another important point. When the errors are cleared, the braking system works but is not corrected by the electronics. Therefore, before buying the “iron horse” should be checked. Enough acceleration and abrupt braking. Well, if at the same time one wheel goes on asphalt and the other on the ground. This way you quickly know whether the ABS is working. The operation of the system is recognized by a characteristic beep. And still felt shaking on the pedals. If the car pulls to the side, the wheels will be blocked and the electronic assistant will not function.
Much depends on the design of the node. If the car is old, the anti-lock braking system consists of a so-called passive sensor and a gear ring on the drive, also called a “comb”. Constant dirt on the comb weakens the sensor signal. So there are several “glitches”. For example, when braking at a speed of about 20 km/h, the system is activated. If you relax, someone may come to the rear bumper. Therefore, gear rings must be cleaned regularly. And they rust and may even crack. This causes vibrations to appear on the steering wheel and the system sensors don’t like that, so they give errors.
Therefore, the car must be hoisted on a lift and inspected before purchase. Pay attention to the condition of the “combs”, as well as the wire contacts. It is important that there is no wear or damage. Otherwise it will lead to a short circuit. By the way, more often than not, the connections with the ground, that is, with the body, rust. This causes ABS malfunctions.
