What is ABS on a Toyota Yaris 2
ABS stands for Anti Blocking System . It is a device which will make it possible to improve the braking system, in particular during intensive braking. Before the development of ABS, the brake pedal was directly linked to the pads. As soon as you step on the pedal, the pads stick to the discs. The disadvantage with this system is that there may be a chance of skating. With the help of sensors, ABS calculated the braking system. Instead of staying pressed on the discs, the pressure will decrease and then increase various times in a very short time, in order to avoid a blocking complete wheels of your Toyota Yaris 2. Not a single slip, and braking is even more effective.

False contact
Reassemble the ABS sensor cables of your Toyota Yaris 2 and take the electrical 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 fault. Reassemble the wiring, if you find a bad connection it will have to be repaired.

A sensor problem
This is obviously a fairly frequent malfunction on a Toyota Yaris 2. It may be that your depth sounder is sending an erroneous message. In this case, it will suffice to change the sounder in question. You can check the sensors with a oscilloscope .
A problem with the hydraulic block
The ABS of your Toyota Yaris 2 works thanks to a device hydraulic , which will manage the pressure of the brake pads. In the event that this device is defective, the replacement of the ABS unit is generally necessary. In the event that this remains a malfunction of the block, it is often felt when braking.

And this operation happens to be quite expensive, on a Toyota Yaris 2 or on any other model of car. It is important not to leave an ABS witness, for obvious safety reasons.
