A light that comes on is not necessarily an excellent sign. It is easy to believe that it is just a dysfunction resulting from sensors . However, it is essential to pay attention to it. How does ABS work? Why is the light on? What should be done? We will answer all these questions, this way you can take the wheel of your Toyota Supra Mkiii with confidence.
What is ABS on a Toyota Supra Mkiii
ABS means Anti Blocking System . It is a system which will make it possible to improve the braking system, inter alia during continuous braking. Before the creation of ABS, the brake pedal was directly linked to the pads. When the pedal was depressed, the pads tightened on the discs. The trouble with this mechanism is that there can be a chance of slippage. Using sensors, ABS assesses the braking system. Instead of staying pressed on the discs, the pressure will vary several times in a very short time, in order to avoid a blocking overall tire size for the Toyota Supra Mkiii. No skidding, and braking is more efficient.
Toyota Supra Mkiii: why the ABS warning light is on
When the ABS warning light remains on, it is certain that the Toyota Supra Mkiii has a malfunction. As with all the other indicator lights, it is relatively usual for this to concern just a malfunction of the electrical connection. However, it is better to be sure.
False contact
Follow the lines of the ABS sounders of the Toyota Supra Mkiii and measure the electric voltage with a multimeter . If one of them does not hold the same value as the others, it is because there is a false contact. Follow the cables, if you find a connection fault you must correct it. If a wire is damaged, it must be replaced.
A sensor problem
This is obviously a relatively common malfunction on a Toyota Supra Mkiii. It happens that the sonar sends an erroneous message. In this specific case, it will suffice to replace the problematic sonar. It is possible to test the sensors using a oscilloscope .
A problem with the hydraulic block
The ABS of the Toyota Supra Mkiii works thanks to a system hydraulic , which will manage the force of the brake pads. In the event that this system is deficient, replacement of the ABS block is generally necessary. When this remains a block malfunction, it usually feels when you brake.
Conclusion
An ABS warning light that stays on may be due to a variety of reasons. Either a sonar malfunction, an electrical fault. In the event that the ABS unit fails, it must certainly be changed. And this operation is rather expensive, on a Toyota Supra Mkiii or on any other car model. It is essential not to abandon an ABS witness, for obvious security reasons.
