An indicator light that trips is not a good sign. You may think it's just a problem with sensors . On the other hand, it is wiser to pay attention to it. What is the role of ABS? Why does the indicator light come on? How to do? We will answer all of these questions, so that you can get behind the wheel of your seat altea safely.indicator-abs-seat-altea

What is ABS on a seat altea

ABS means Anti Blocking System . It is a mechanism that improves your braking, especially for sustained brake applications. Before the creation of ABS, the brake pedal was simply linked to the pads. When pressed, the pads closed on the discs. The downside with this process is that there can be a chance of skidding. Using sensors, ABS calculated the braking system. Instead of staying pressed on the discs, the pressure will vary various times per second, thus preventing a blocking overall seat altea tires. No skidding, and braking becomes much more efficient.

seat altea: why the ABS warning light is on

If the ABS warning light comes on, it is certain that this seat altea has a problem. As with all the other witnesses, it is quite ordinary that it simply concerns a problem of contact. However, it is better to be sure.

False contact

Reassemble the ABS probe cables of this seat altea and take the electrical voltage with the help of a multimeter . If one of them does not have the same value as the other three, there is an electrical problem. Reassemble the line, if you find a bad connection it must be repaired. If a wire is damaged, it must be changed.

A sensor problem

This is naturally a fairly common problem for a seat altea. Sometimes the sensor sends the wrong message. Therefore, it will suffice to change the sonar in question. You can test the sensors using a oscilloscope .

A problem with the hydraulic block

The ABS of this seat altea works using a device hydraulic , which manages the pressure of the brake pads. In the event that this device is defective, changing the ABS block is usually essential. If it's a problem with the boulder, you can often feel it when you brake.

Conclusion

An ABS warning light that comes on can come from quite distinct causes. Either a sonar problem, an electrical fault. Assuming the ABS unit has failed, it probably needs to be changed. And this intervention happens to be quite expensive, for a seat altea or for any other type of automobile. It is wiser not to neglect an ABS witness, for obvious safety reasons.
