A light that is on is not a good sign. You may think that this is simply a problem arising from sensors . However, it is wiser to pay attention to it. What is ABS used for? Why does the light come on? How to do? We will answer all of these questions, so you can drive the Toyota Corona with confidence.
What is ABS on a Toyota Corona
ABS means Anti Blocking System . It is a mechanism which will make it possible to improve the braking system, inter alia during intensive braking. Before the creation of ABS, the brake pedal was simply linked to the pads. When pressed, the pads tightened on the discs. The disadvantage with this device is that there is a chance of skating. Using sensors, ABS assesses braking. Instead of leaning on the discs, the pressure will vary a certain number of times in a very short time, which avoids a blocking overall wheels of the Toyota Corona. No skating, and braking becomes more efficient.
Toyota Corona: why the ABS warning light is on
In the event that the ABS warning light remains on, it is certain that the Toyota Corona has a problem. As with all other indicators, it is quite common that it simply concerns a contact problem. However, it's better to be sure.
False contact
Follow the cables of the ABS sensors of the Toyota Corona and measure the electric current using a multimeter . When one of them does not have the same value as the other three, it means that there is an electrical fault. Reassemble the cables, if you find a connection fault it must be repaired. When a cable is damaged, it must be replaced.
A sensor problem
This remains of course a fairly recurring problem for a Toyota Corona. Your detector may issue an erroneous message. In this specific case, it will suffice to replace the problematic sensor. You will be able to test the sensors using a oscilloscope .
A problem with the hydraulic block
The ABS of the Toyota Corona works using a device hydraulic , which manages the force of the brake pads. If ever this device is deficient, the change of the ABS block is generally compulsory. In the event that this remains a block problem, you can generally feel it when braking.
Conclusion
An ABS warning light that stays on can come from very different causes. Either a sensor problem, an electrical fault. Assuming your ABS unit is damaged, it probably needs to be changed. And this operation is relatively expensive, for a Toyota Corona or for any other car model. It is wiser not to neglect an ABS warning light, for understandable safety reasons.
