What is ABS on a Toyota Highlander

ABS stands for Anti Blocking System . It is a system which will make it possible to perfect the braking system, in particular for intensive braking. Before the invention of ABS, the brake pedal was simply connected to the pads. When pressed, the pads stick to the discs. The downside with this mechanism is that there is a chance of skating. With the help of probes, ABS assesses braking. Instead of pressing on the discs, the pressure will vary various times per second, thus avoiding a blocking overall wheels of the Toyota Highlander. No skating, and braking becomes much more efficient.

Assuming that one of them does not have the same value as the other three, there is an electrical problem. Reassemble the cables, if you find a bad connection you will have to adjust it. If a wire is damaged, it must be replaced.

A sensor problem

This is naturally a fairly common problem for a Toyota Highlander. Your detector may send the wrong message. So it will be enough to replace the problematic sonar. You can control the probes using a oscilloscope .

A problem with the hydraulic block

The ABS of the Toyota Highlander operates using a system hydraulic , which will manage the strength of the brake pads. In the event that this system fails, changing the ABS unit is generally compulsory. If this remains a problem of the block, it is generally felt when braking.
