An indicator light that comes on is not necessarily a good sign. It is easy to think that it is simply a problem arising from sensors . That said, it is essential to pay attention to it. What is ABS used for? Why does the indicator light come on? what are the solutions? We will answer all of these questions, so you can drive your Toyota I-unit safely.warning-abs-Toyota-I-unit

What is ABS on a Toyota I-unit

ABS stands for Anti Blocking System . It is a device which will make it possible to perfect the braking system, among other things for intensive braking. Before the development of ABS, the brake pedal was directly linked to the pads. As soon as you pressed, the pads tightened on the discs. The disadvantage with this process is that there is a risk of slipping. Using probes, ABS calculated the braking system. Instead of leaning on the discs, the pressure will oscillate a certain number of times in a very short time, in order to prevent a blocking overall tire size for the Toyota I-unit. Not a single skid, and the braking is much more efficient.

Toyota I-unit: why the ABS warning light is on

When the ABS warning light is on, there is no question that the Toyota I-unit has a problem. As on all the other indicators, it is quite usual that it is simply a problem of contact. That said, it's better to be sure.

False contact

Follow the wiring of the ABS probes of the Toyota I-unit and measure the electric voltage using a multimeter . If one of them does not hold the same value as the other three, there is an electrical problem. Follow the cables, if you find a connection fault you will have to troubleshoot it. When a wire is in poor condition, it will need to be replaced.

A sensor problem

This is of course a fairly common problem for a Toyota I-unit. It happens that your sensor sends an erroneous message. In this situation, it will suffice to replace the sensor concerned. You will be able to control the probes using a oscilloscope .

A problem with the hydraulic block

ABS of Toyota I-unit works with a device hydraulic , which gives the opportunity to manage the intensity of the brake pads. If ever this device is deficient, the replacement of the ABS unit is generally essential. When it's a block problem, you can usually feel it when braking.

Conclusion

An ABS warning light that stays on can come from quite different causes. Whether it's a sensor problem, an electrical fault. If your ABS unit is non-functional, it will probably have to be changed. And this operation is relatively expensive, for a Toyota I-unit or for any type of car. It is essential not to neglect an ABS warning light, for obvious safety reasons.
