A light that is on is not necessarily a good sign. You may think it's just a concern from sensors . On the other hand, it is essential to pay attention to it. How does ABS work? Why is the light on? What should be done? We will try to clarify all of these questions, so you can drive your Toyota Rav 4 (2nd Generation) safely.
What is ABS on a Toyota Rav 4 (2nd Generation)
ABS stands for Anti Blocking System . It is a device which will make it possible to improve the braking system, inter alia during sustained brake applications. Before the development of ABS, the brake pedal was directly linked to the pads. When pressed, the pads tightened on the discs. The disadvantage with this mechanism is that there is a chance of slippage. Thanks to probes, ABS assesses braking. Instead of leaning on the discs, the pressure will vary a certain number of times in a very short time, which avoids a blocking complete set of tires for your Toyota Rav 4 (2nd Generation). Not a single skid, and braking is even more efficient.
Toyota Rav 4 (2th Generation): why the ABS warning light is on
If the ABS warning light is on, there is no question that this Toyota Rav 4 (2nd Generation) has a problem. As with all the other indicator lights, it is relatively usual for it to be just a concern for contact. That said, it is better to be sure.
False contact
Reassemble the ABS sensor cables of this Toyota Rav 4 (2nd Generation) and measure the electric current with a multimeter . When one of them does not hold the same value as the other three, it is because there is a false contact. Reassemble the line, if you discover a bad connection it is necessary to repair it. When a wire is damaged, it is necessary to replace it.
A sensor problem
This obviously remains a relatively common concern on a Toyota Rav 4 (2nd Generation). It happens that your sonar sends an erroneous message. Therefore, it will suffice to replace the sensor in question. It is possible to check the probes using a oscilloscope .
A problem with the hydraulic block
The ABS of this Toyota Rav 4 (2nd Generation) works using a system hydraulic , which allows you to manage the intensity of the brake pads. In the event that this system is defective, changing the ABS unit is usually necessary. If it is a problem of the block, it is generally felt when braking.
Conclusion
The ABS warning light that trips can come from a variety of causes. Either a sensor problem, a false contact. If your ABS unit is non-functional, it is probably necessary to replace it. And this intervention is rather expensive, on a Toyota Rav 4 (2nd Generation) or on any other type of automobile. It is essential not to abandon an ABS warning light, for understandable safety reasons. Leave a comment if this special ABS witness record was useful. Good road!
