What is ABS on a Toyota Rav 4

ABS stands for Anti Blocking System . It is a system that offers the possibility of improving braking, especially during sustained braking. Before the invention of ABS, the brake pedal was simply linked to the pads. When pressed, the pads tightened on the discs. The inconvenience with this device is that there may be a chance of slippage. With the help of probes, ABS assesses braking. Instead of remaining pressed on the discs, the pressure will vary various times in a very short time, in order to avoid a blocking complete tires of your Toyota Rav 4. No skidding, and braking becomes more efficient.

False contact

Reassemble the cables of the ABS probes of your Toyota Rav 4 and read the electric current with the help of a multimeter . If one of them does not hold the same value as the other three, it is because there is a false contact. Follow the cables, if you find a bad connection you will have to troubleshoot it. If ever a wire is in bad condition, it will have to be changed.

A sensor problem

This is naturally a fairly common concern for a Toyota Rav 4. It is possible that the detector sends a bad message. In this specific case, it will suffice to change the problematic sonar. You can test the probes using a oscilloscope .

A problem with the hydraulic block

The ABS of your Toyota Rav 4 works using a device hydraulic , which manages the pressure of the brake pads. If this device is ever damaged, replacement of the ABS unit is generally necessary. In case this remains a concern of the block, we can usually feel it when braking.

Conclusion
