What is ABS on a Seat Arosa

ABS means Anti Blocking System . It is a device that improves the braking system, among other things for sustained braking. Before ABS development, the brake pedal was directly connected to the pads. When the pedal was depressed, the pads closed on the discs. The trouble with this device is that there may be a risk of skating. Thanks to probes, ABS calculated the braking system. Instead of holding the discs, the pressure will oscillate various times per second, which avoids a blocking overall tires for your Seat Arosa. No skating, and braking becomes even more efficient.

Seat Arosa: why the ABS warning light is on

If the ABS warning light remains on, there is no question that this Seat Arosa has a problem. As with all other indicator lights, it is quite common that it simply concerns an electrical connection problem. However, it is better to be sure.

False contact

Follow the ABS sensor cables of this Seat Arosa and measure the electric voltage using a multimeter . Supposing that one of them does not have the same value as the others, it means that there is an electrical problem. Reassemble the wiring, if you discover a bad connection it must be adjusted. If ever a cable is in bad condition, it must be changed.

A sensor problem

This is indeed a fairly common problem on a Seat Arosa. The sonar may be sending the wrong message. In this case, it will suffice to change the sonar in question. You can control the probes with a oscilloscope .

A problem with the hydraulic block

The ABS of this Seat Arosa works thanks to a mechanism hydraulic , which allows you to manage the intensity of the brake pads. In the event that this mechanism is defective, replacement of the ABS unit is generally necessary. If this is still a block problem, you can usually feel it when you brake.

Conclusion

The ABS warning light that comes on can come from quite different causes. Whether it's a sonar problem, a false contact. Assuming the ABS unit has failed, it probably needs to be changed. And this intervention is quite expensive, on a Seat Arosa or on each type of vehicle. It is wiser not to leave an ABS warning light, for obvious safety reasons. You can write a comment in case this special ABS indicator light file served you. See you soon!
