Why is the light on? What to do? We will answer all these questions, so you can take the wheel of your Seat Mii with confidence.indicator-abs-Seat-Mii

What is ABS on a Seat Mii

ABS means Anti Blocking System . It is a system that improves braking, especially during intensive braking. Before the creation of ABS, the brake pedal was directly linked to the pads. When the pedal was depressed, the pads closed on the discs. The trouble with this system is that there can be a risk of slippage. Using probes, ABS calculated braking. Instead of holding the discs, the pressure will oscillate several times in a very short time, thus avoiding a blocking total tires of the Seat Mii. No skidding, and braking becomes much more efficient.

Seat Mii: why the ABS warning light is on

If the ABS warning light remains on, it is certain that this Seat Mii has a malfunction. As with all of the other indicator lights, it is quite common that it just concerns a contact malfunction. However, it's better to be sure.

False contact

Follow the wiring of the ABS probes of this Seat Mii and measure the electric voltage with a multimeter . In the event that one of them does not have the same value as the other three, it means that there is a false contact. Reassemble the line, if you find a connection fault you will have to troubleshoot it. If a wire is in bad condition, you will have to replace it.

A sensor problem

This is of course a rather common malfunction for a Seat Mii. It happens that your detector sends an erroneous message. In this situation, it will suffice to replace the sounder in question. You can check the probes using a oscilloscope .

A problem with the hydraulic block

The ABS of this Seat Mii works using a mechanism hydraulic , which manages the force of the brake pads. In the event that this mechanism is damaged, changing the ABS unit is usually mandatory. If this remains a block malfunction, it can usually be felt when braking.

Conclusion

An ABS warning light that stays on may be the result of very different reasons. Whether it is a sonar malfunction, a false contact. If your ABS unit is defective, you will probably have to replace it. And this operation is quite expensive, for a Seat Mii or for any type of car. It is essential not to neglect an ABS witness, for obvious security reasons. Do not hesitate to leave a comment in case this special ABS witness file was useful. Good walk!
