What is an ABS on a Renault Clio 4 Rs
ABS means Anti Blocking System . It is a mechanism that offers the possibility of perfecting braking, among other things for intensive braking. Before the invention of ABS, the brake pedal was directly linked to the pads. When the pedal was depressed, the pads closed on the discs. The trouble with this system is that there is a chance of slippage. Thanks to probes, ABS assesses braking. Instead of holding the discs, the pressure will oscillate various times per second, which avoids a blocking total tires of the Renault Clio 4 Rs. No skidding, and braking is more efficient.

False contact
Reassemble the ABS sensor cables of the Renault Clio 4 Rs and read the electrical current with the help of a multimeter . In the event that one of them does not have the same value as the others, it means that there is an electrical fault. Reassemble the line, if you find a bad connection you will have to adjust it. If ever a wire is damaged, it will have to be changed.
A sensor problem
This is of course a fairly common problem on a Renault Clio 4 Rs. Your detector may send an erroneous message. In this case, it will suffice to change the sounder in question. You will be able to control the probes using a oscilloscope .
A problem with the hydraulic block
The ABS of the Renault Clio 4 Rs works using a system hydraulic , which will manage the intensity of the brake pads. In the event that this system is deficient, replacement of the ABS unit is generally necessary. If this remains a problem with the block, you can usually feel it when you brake.
Conclusion
An ABS warning light that comes on can come from very different causes. Whether it's a sonar problem, an electrical fault. If your ABS unit fails, it will probably have to be changed. And this operation is relatively expensive, on a Renault Clio 4 Rs or on any type of car. It is essential not to abandon an ABS witness, for obvious safety reasons.
