What is ABS on a Toyota Previa 2

ABS stands for Anti Blocking System . It is a mechanism that offers the possibility of improving your braking, especially for sustained braking. Before the invention of ABS, the brake pedal was simply connected to the pads. As soon as you pressed, the pads tightened on the discs. The downside with this mechanism is that there may be a chance of skating. Thanks to sensors, ABS calculated the braking system. Instead of being pressed on the discs, the pressure will vary several times in a very short time, thus preventing a blocking total wheels of the Toyota Previa 2. Not a single slip, and braking becomes much more efficient.

Toyota Previa 2: why the ABS warning light is on

If the ABS warning light remains on, there is no doubt that your Toyota Previa 2 has a problem. As with all the other indicator lights, it is rather usual that it only concerns an electrical connection problem. However, it is better to be certain.

False contact

Reassemble the ABS sensor cables of your Toyota Previa 2 and take the electrical current using a multimeter . If one of them does not have the same value as the other three, then there is an electrical fault. Follow the cables, if you find a bad connection you will have to adjust it. When a cable is in poor condition, it will have to be replaced.

A sensor problem

This is obviously a fairly common problem for a Toyota Previa 2. The detector may be sending the wrong message. In this case, it will suffice to replace the sonar in question. You will be able to control the sensors using a oscilloscope .

A problem with the hydraulic block

The ABS of your Toyota Previa 2 works using a device hydraulic , which manages the force of the brake pads. When this device is damaged, changing the ABS unit is generally necessary. If it is a block problem, you can often feel it when braking.

Conclusion

The ABS warning light that is triggered can come from many different reasons. Either a sonar problem, a false contact. In case the ABS unit is damaged, it will probably have to be changed. And this intervention happens to be relatively expensive, for a Toyota Previa 2 or for any type of automobile. It is essential not to neglect an ABS warning light, for obvious safety reasons.
