A light that comes on is not a great sign. You might think that this is quite simply a concern coming from sensors . However, it is essential to pay attention to it. How does an ABS work? Why is the light on? what are the solutions? We will try to clarify all of these questions, so that you can take the wheel of your Toyota Hilux 4 with confidence.
What is ABS on a Toyota Hilux 4
ABS means Anti Blocking System . It is a device that improves braking, among other things for continuous braking. Before the development of ABS, the brake pedal was simply linked to the pads. When you pressed, the pads tightened on the discs. The inconvenience with this mechanism is that there may be a risk of skidding. With the help of the sensors, the ABS assesses braking. Instead of maintaining the discs, the pressure will decrease and then increase a certain number of times in a very short time, in order to prevent a blocking overall tire performance of the Toyota Hilux 4. No skidding, and braking becomes more efficient.
Toyota Hilux 4: why the ABS warning light is on
When the ABS warning light comes on, your Toyota Hilux 4 certainly has a problem. As on all the other LEDs, it is quite ordinary that it simply concerns a contact problem. However, it is better to be assured of this.
False contact
Follow the lines of the ABS sensors of your Toyota Hilux 4 and measure the electrical intensity using a multimeter . If one of them does not have the same value as the other three, there is an electrical fault. Follow the wiring, if you find a bad connection it is necessary to rectify it. When a wire is damaged, it is necessary to replace it.
A sensor problem
This is of course a fairly recurring problem on a Toyota Hilux 4. It is possible that the detector is sending an incorrect message. So, it will suffice to replace the sensor concerned. You can control the sensors using a oscilloscope .
A problem with the hydraulic block
The ABS in your Toyota Hilux 4 works using a system hydraulic , which manages the pressure of the brake pads. If ever this system is defective, changing the ABS unit is often mandatory. When this remains a blocking problem, it can often be felt when braking.
Conclusion
The ABS warning light that comes on can be for quite a variety of reasons. Either a problem with the sensor, a false contact. If the ABS unit is not functional, it is probably necessary to change it. And this intervention is quite expensive, on a Toyota Hilux 4 or any other type of automobile. It is essential not to neglect an ABS warning light, for obvious safety reasons.
