A light that comes on is never a good sign. You may think it’s just a problem with sensors . However, it is essential to pay attention to it. How does ABS work? Why does the light come on? What should be done? We will answer these questions, this way you can take the wheel of your Toyota Rav 4 (3rd Generation) with confidence.warning-abs-Toyota-Rav-4- (3th-Generation)

What is ABS on a Toyota Rav 4 (3nd Generation)

ABS means Anti Blocking System . It is a system that offers the possibility of improving the braking system, among other things for intensive braking. Before the creation of ABS, the brake pedal was simply linked to the pads. When pressed, the pads closed on the discs. The trouble with this system is that there may be a chance of slippage. Using probes, ABS assesses the braking system. Instead of maintaining the discs, the pressure will decrease and then increase a certain number of times in a very short time, thus avoiding a blocking overall wheels of the Toyota Rav 4 (3rd Generation). Not a single skid, and the braking is even more efficient.

Toyota Rav 4 (3th Generation): why the ABS warning light is on

If the ABS warning light comes on, there is no question that this Toyota Rav 4 (3rd Generation) has a problem. As with all the other witnesses, it is rather frequent that it simply concerns a problem of contact. However, it is better to be insured.

False contact

Reassemble the ABS sensor wiring for this Toyota Rav 4 (3rd Generation) and read the electrical voltage using a multimeter . In the event that one of them does not have the same value as the others, it means that there is an electrical fault. Follow the cables, if you find a bad connection it is necessary to correct it. When a cable is damaged, it must be replaced.

A sensor problem

This is naturally a rather recurring problem on a Toyota Rav 4 (3rd Generation). The sonar may be sending the wrong message. Therefore, it will suffice to replace the sensor in question. You can control the probes using a oscilloscope .

A problem with the hydraulic block

The ABS of this Toyota Rav 4 (3rd Generation) works using a system hydraulic , which manages the force of the brake pads. In the event that this system is deficient, the replacement of the ABS block is usually necessary. In case it is a problem with the block, it is generally felt when braking.

Conclusion

An ABS warning light that can be triggered can come from very different reasons. Either a sensor problem, a false contact. If the ABS unit is ever defective, it is probably necessary to change it. And this operation is quite expensive, on a Toyota Rav 4 (3rd Generation) or on any vehicle model. It is essential not to neglect an ABS warning light, for obvious safety reasons.
