What is ABS on a Toyota Prius 4 Rechargeable
ABS means Anti Blocking System . It is a system which offers the possibility of perfecting the braking system, in particular for sustained braking. Before the invention of ABS, the brake pedal was directly connected to the pads. As soon as you depressed the pedal, the pads stuck to the discs. The disadvantage with this device is that there may be a risk of slipping. By means of the sensors, the ABS calculated the braking system. Instead of pressing on the discs, the pressure will vary a certain number of times per second, thus preventing a blocking overall tires of the Toyota Prius 4 Rechargeable. No slippage, and braking becomes much more efficient.
Toyota Prius 4 Rechargeable: why the ABS warning light is on
If the ABS warning light remains on, there is no doubt that your Toyota Prius 4 Rechargeable has a problem. As on all the other indicator lights, it is quite common that it simply concerns a contact problem. However, it is better to be sure.
False contact
Reassemble the lines of the ABS sensors of your Toyota Prius 4 Rechargeable and read the electrical voltage with a multimeter . When one of them does not have the same value as the others, there is an electrical problem. Reassemble the cables, if you find a connection fault it will have to be fixed. When a thread is damaged, it will have to be changed.
A sensor problem
This is indeed a fairly recurring concern on a Toyota Prius 4 Rechargeable. Your sensor may be sending an incorrect message. So, it will suffice to change the sensor in question. You will be able to test the sensors using a oscilloscope .
A problem with the hydraulic block
The ABS of your Toyota Prius 4 Rechargeable works by means of a mechanism hydraulic , which will manage the intensity of the brake pads. In the event that this mechanism is deficient, changing the ABS unit is generally essential. In the event that it is a problem with the block, it is usually felt when braking.
Conclusion
An ABS warning light that comes on can have many causes. Either a sensor problem, a false contact. Supposing that your ABS unit is faulty, it will certainly have to be changed. And this intervention is relatively expensive, on a Toyota Prius 4 Rechargeable or on each type of vehicle. It is wiser not to neglect an ABS warning light, for obvious safety reasons.
