A light that turns on is never an excellent omen. You may think that this is simply a dysfunction coming from sensors . However, it is essential to pay attention to it. What is the role of ABS? Why does the light come on? What should be done? We will try to elucidate these questions, so that you can drive the Renault Espace 3 safely.
What is ABS on a Renault Espace 3
ABS means Anti Blocking System . It is a mechanism that offers the possibility of improving braking, especially for intensive braking. Before the creation of ABS, the brake pedal was directly linked to the pads. When the pedal was depressed, the pads tightened on the discs. The downside with this system is that there is a risk of slippage. Thanks to probes, ABS assesses braking. Instead of holding the discs, the pressure will oscillate various times in a very short time, thus preventing a blocking total wheels of the Renault Espace 3. Not a single slip, and braking is more efficient.
Renault Espace 3: why the ABS warning light is on
If the ABS warning light is on, it is certain that the Renault Espace 3 has a malfunction. As on all the other indicators, it is quite common for this to be quite simply a contact malfunction. However, it's better to be sure.
False contact
Reassemble the cables of the sounders of the ABS of the Renault Espace 3 and take the electric current with 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 problem. Follow the wiring, if you find a bad connection you will have to troubleshoot it. When a cable is in bad condition, it will have to be changed.
A sensor problem
This naturally remains a fairly common malfunction for a Renault Espace 3. It is possible that your sensor sends an erroneous message. In this specific case, it will suffice to change the sensor concerned. It is possible to test the probes using a oscilloscope .
A problem with the hydraulic block
The ABS of the Renault Espace 3 works using a system hydraulic , which allows you to manage the intensity of the brake pads. In the event that this system is defective, replacement of the ABS unit is generally essential. In the event that this remains a malfunction of the block, it is often felt when braking.
Conclusion
An ABS warning light that stays on can come from quite different reasons. Whether it is a sensor malfunction, a false contact. In case your ABS unit is not functional, it will probably have to be changed. And this intervention happens to be rather expensive, for a Renault Espace 3 or for any other type of car. It is essential not to neglect an ABS warning light, for obvious safety reasons. You can write a comment in case this special ABS witness file was useful to you. See you soon!
