What is ABS on a Renault Espace 4

ABS means Anti Blocking System . It is a device which will make it possible to improve the braking system, in particular during sustained brake applications. Before the creation of ABS, the brake pedal was directly connected to the pads. When pressed, the pads closed on the discs. The inconvenience with this device is that there is a risk of slipping. With the help of probes, ABS assesses the braking system. Instead of holding the discs, the pressure will oscillate a certain number of times per second, thus making it possible to prevent a blocking total wheels of the Renault Espace 4. No skidding, and braking becomes much more efficient.

Renault Espace 4: why the ABS warning light is on

If the ABS warning light is on, it is certain that this Renault Espace 4 presents a problem. As with all of the other indicator lights, it is quite ordinary that it is just a concern for contact. However, it is better to be insured.

False contact

Raise the ABS probe lines of this Renault Espace 4 and measure the electrical voltage using a multimeter . Supposing that one of them does not hold the same value as the other three, it means that there is a false contact. Follow the line, if you find a connection fault you will have to troubleshoot it. If a wire is damaged, you will have to replace it.

A sensor problem

This naturally remains a fairly frequent concern on a Renault Espace 4. The sounder may send the wrong message. In this specific case, it will suffice to replace the sounder in question. It is possible to test the probes using a oscilloscope .

A problem with the hydraulic block

The ABS of this Renault Espace 4 operates using a mechanism hydraulic , which gives the opportunity to manage the intensity of the brake pads. In the event that this mechanism fails, changing the ABS unit is usually necessary. If this remains a problem of block, it is often felt when braking.

Conclusion

The ABS warning light which comes on may come from quite different causes. Whether it's a sonar problem, a false contact. If the ABS unit is damaged, you will probably have to change it. And this operation happens to be relatively expensive, on a Renault Espace 4 or on any other type of vehicle. It is essential not to neglect an ABS witness, for obvious safety reasons. Leave us a comment in case this specific ABS warning light file was useful. Enjoy the road!
