What is ABS on a Toyota Avensis 4

ABS means Anti Blocking System . It is a mechanism which makes it possible to improve braking, especially during intensive braking. Before the development of ABS, the brake pedal was directly linked to the pads. As soon as you depressed the pedal, the pads stuck to the discs. The downside with this device is that there may be a chance of slippage. By means of the sensors, the ABS assesses braking. Instead of holding the discs, the pressure will decrease and then increase several times per second, to avoid a blocking complete the tires of your Toyota Avensis 4. No skidding, and braking is much more efficient.

Toyota Avensis 4: why the ABS warning light is on

If the ABS warning light remains on, there is no doubt that this Toyota Avensis 4 has a problem. As on all the other LEDs, it is rather usual that this concerns quite simply a concern of contact. Still, it is better to be sure.

False contact

Reassemble the lines of the ABS sensors of this Toyota Avensis 4 and measure the electrical voltage with a multimeter . Assuming that one of them does not have the same value as the other three, there is an electrical fault. Follow the wiring, if you discover a connection fault it is necessary to repair it. When a wire is in bad condition, it is necessary to change it.

A sensor problem

This is obviously a rather frequent problem on a Toyota Avensis 4. It is possible that your detector emits the wrong message. In this specific case, it will suffice to change the problematic sounder. You can check the sensors with a oscilloscope .

A problem with the hydraulic block

The ABS of this Toyota Avensis 4 works thanks to a mechanism hydraulic , which manages the pressure of the brake pads. In the event that this mechanism is defective, changing the ABS unit is often necessary. If it's a block problem, it usually shows when braking.

Conclusion

The ABS warning light that activates can come from many causes. Either a sounder concern, an electrical fault. If your ABS unit is damaged, it is certainly necessary to replace it. And this intervention is rather expensive, on a Toyota Avensis 4 or on each type of vehicle. It is wiser not to neglect an ABS warning light, for understandable safety reasons.
