If that ABS indicator is on the safest thing is because obviously it is not working, now the following, if it gives you that error is due to the electrovalve that controls the ABS system is the one that is responsible for sending or blocking the flow of the liquid to the brakes and if that relay is damaged the most convenient thing is that you take a specialized dealership because if you start to fix that it is most likely. necessary fluid to stop, also that you may need welding or a change of the piece ... It can be said that the brakes is the most important part of the car and that is why my recommendation ... luck !!!
