An indicator that lights up is in no way a good omen. You may think it's just a dysfunction related to sensors . However, it is wiser to pay attention to it. How does ABS work? Why does the witness go off? What should be done? We will answer all these questions, so you can take the wheel of the Seat Altea Freetrack with confidence.indicator-abs-Seat-Altea-Freetrack

What is ABS on a Seat Altea Freetrack

ABS means Anti Blocking System . It is a mechanism that improves your braking, especially during continuous braking. Before the creation of ABS, the brake pedal was directly connected to the pads. As soon as the pedal was depressed, the pads tightened on the discs. The downside with this system is that there can be a risk of skidding. Thanks to sensors, ABS calculated braking. Instead of holding the discs, the pressure will oscillate various times per second, which avoids a blocking total wheels of the Seat Altea Freetrack. Not a single skid, and braking becomes much more effective.

Seat Altea Freetrack: why the ABS warning light is on

If the ABS warning light remains on, there is no doubt that this Seat Altea Freetrack has a malfunction. As with all of the other indicator lights, it is quite common for it to be just a contact malfunction. However, it's better to be assured.

False contact

Follow the ABS sensor cables of this Seat Altea Freetrack and measure the electric voltage with the help of a multimeter . In the event that one of them does not have the same value as the other three, there is an electrical problem. Reassemble the wiring, if you find a bad connection it is necessary to troubleshoot it. When a wire is in bad condition, it is necessary to change it.

A sensor problem

This is obviously a fairly frequent malfunction on a Seat Altea Freetrack. Sometimes the sensor sends the wrong message. In this case, it will suffice to change the sensor in question. You can check the sensors using a oscilloscope .

A problem with the hydraulic block

The ABS of this Seat Altea Freetrack works using a system hydraulic , which will manage the intensity of the brake pads. In the event that this system fails, replacement of the ABS unit is generally essential. If it remains a block malfunction, it is usually felt when braking.

Conclusion

An ABS warning light that comes on can come from a variety of causes. Whether it is a sensor malfunction, an electrical fault. If the ABS unit is not functional, it is probably necessary to change it. And this intervention happens to be rather expensive, on a Seat Altea Freetrack or on each type of automobile. It is wiser not to abandon an ABS witness, for obvious safety reasons. Do not hesitate to leave a comment in case this special ABS witness text was useful to you. See you soon!
