A light that goes off is not a good sign. One can think that it is only a dysfunction resulting from the sensors . Nevertheless, it is essential to pay attention to it. What is the role of ABS? Why is the light on? How to do? We will try to elucidate all of these questions, so that you can drive the Toyota Corolla 7 with confidence.
What is ABS on a Toyota Corolla 7
ABS stands for Anti Blocking System . It is a system that offers the possibility of improving the braking system, among other things for intensive braking. Before the creation of ABS, the brake pedal was directly linked to the pads. As soon as you pressed, the pads closed on the discs. The inconvenience with this mechanism is that there may be a chance of slippage. Thanks to sensors, ABS assesses braking. Instead of holding the discs, the pressure will oscillate a number of times per second, to prevent a blocking total tires of the Toyota Corolla 7. No skidding, and braking becomes much more efficient.
Toyota Corolla 7: why the ABS warning light is on
When the ABS warning light comes on, the Toyota Corolla 7 is sure to have a malfunction. As on all the other witnesses, it is rather frequent that it concerns only a malfunction of electrical connection. However, it's better to be sure.
False contact
Wind the lines of the ABS probes of the Toyota Corolla 7 and take the electric current with a multimeter . When one of them does not have the same value as the others, it means that there is an electrical fault. Reassemble the wiring, if you find a connection fault you will have to resolve it. When a wire is in bad condition, you will have to change it.
A sensor problem
This is indeed a rather frequent malfunction on a Toyota Corolla 7. It is possible that your sensor sends an erroneous message. Therefore, it will suffice to change the sensor concerned. It is possible to check the sensors using a oscilloscope .
A problem with the hydraulic block
The ABS of the Toyota Corolla 7 works using a mechanism hydraulic , which will manage the force of the brake pads. When this mechanism is damaged, replacement of the ABS unit is usually necessary. When this remains a malfunction of the block, it is generally felt by braking.
Conclusion
The ABS warning light that comes on may be due to very different reasons. Either a sensor malfunction, an electrical fault. If your ABS unit is faulty, you will probably have to replace it. And this intervention is quite expensive, on a Toyota Corolla 7 or on any model of automobile. It is essential not to abandon an ABS witness, for understandable security reasons.
