A light that is on is never a great sign. You may think that this is simply a problem related to sensors . However, it is important to pay attention to it. How does ABS work? Why does the light go on? What should be done? We will answer these questions, so you will be able to drive and be confident about your Renault Juvaquatre.warning-abs-Renault-Juvaquatre

What is an ABS on a Renault Juvaquatre

ABS stands for Anti Blocking System . It is a device which will make it possible to improve the braking system, in particular for continuous braking. Before the invention of ABS, the brake pedal was directly linked to the pads. As soon as you pressed, the pads tightened on the discs. The trouble with this device is that there is a risk of slipping. Using probes, ABS calculated the braking system. Instead of holding the discs, the pressure will oscillate several times per second, to prevent a blocking overview of the Renault Juvaquatre wheels. Not a single skid, and braking becomes more efficient.

Renault Juvaquatre: why the ABS warning light is on

When the ABS warning light comes on, it is certain that your Renault Juvaquatre has a problem. As with all of the other indicator lights, it is relatively ordinary that this simply concerns a contact problem. However, it is better to be sure.

False contact

Follow the lines of the ABS probes of your Renault Juvaquatre and read the electrical intensity with a multimeter . If one of them does not have the same value as the other three, it is because there is an electrical problem. Reassemble the wiring, if you discover a connection fault you will have to resolve it. If a cable is damaged, it must be replaced.

A sensor problem

This is naturally a relatively frequent problem for a Renault Juvaquatre. Your detector may be sending the wrong message. In this specific case, it will suffice to replace the sensor concerned. It is possible to check the probes using a oscilloscope .

A problem with the hydraulic block

The ABS of your Renault Juvaquatre works thanks to a mechanism hydraulic , which will manage the pressure of the brake pads. When this mechanism is defective, replacement of the ABS unit is usually necessary. When this remains a problem of the block, it is often felt by braking.

Conclusion

An ABS warning light that comes on can come from quite different reasons. Either a sensor problem, a false contact. Suppose your ABS unit is defective, it will certainly have to be changed. And this operation is quite expensive, for a Renault Juvaquatre or for each model of automobile. It is important not to neglect an ABS warning light, for obvious safety reasons.
