An indicator light that comes on is not necessarily a good sign. One can think that it is simply a dysfunction coming from the sensors . That said, it's wiser to pay attention to it. How does ABS work? Why does the indicator light come on? what are the solutions? We will answer these questions, so you can take the wheel of your Toyota Hilux with confidence.
What is ABS on a Toyota Hilux
ABS stands for Anti Blocking System . It is a device which offers the possibility of improving the braking system, in particular for sustained brake applications. Before the invention of ABS, the brake pedal was directly connected to the pads. When the pedal was depressed, the pads closed on the discs. The trouble with this mechanism is that there is a chance of skating. Using probes, ABS assesses braking. Instead of holding the discs, the pressure will oscillate a number of times in a very short time, which will prevent a blocking complete wheels of your Toyota Hilux. Not a single skate, and braking is much more efficient.
Toyota Hilux: why the ABS warning light is on
If the ABS warning light comes on, your Toyota Hilux is sure to have a malfunction. As with all other indicator lights, it is relatively frequent that this simply concerns a contact malfunction. However, it's better to be sure.
False contact
Follow the wiring of the ABS sounders of your Toyota Hilux and measure the electric voltage with a multimeter . If ever one of them does not have the same value as the other three, it is because there is a false contact. Reassemble the cables, if you discover a connection fault it is necessary to repair it. When a cable is in poor condition, it is necessary to change it.
A sensor problem
This is obviously a relatively common malfunction for a Toyota Hilux. It happens that the sounder sends a bad message. In this situation, it will suffice to change the problematic sensor. You can check the probes using a oscilloscope .
A problem with the hydraulic block
The ABS of your Toyota Hilux works using a device hydraulic , which will manage the pressure of the brake pads. When this device is damaged, changing the ABS unit is generally necessary. If it remains a malfunction of the block, it is generally felt when braking.
Conclusion
An ABS warning light that can be triggered can come from quite distinct causes. Whether it is a sensor malfunction, a false contact. If the ABS unit is not functional, it is probably necessary to replace it. And this operation happens to be rather expensive, for a Toyota Hilux or for any other type of vehicle. It is wiser not to abandon an ABS witness, for obvious safety reasons. Leave us a comment if this special ABS warning light article was useful. Good walk!
