An indicator light that lights up is not necessarily a good omen. It’s easy to think that it’s just a problem with sensors . On the other hand, it is essential to pay attention to it. What is the role of ABS? Why is the indicator light on? What to do? We will answer all of these questions, so you can get behind the wheel of the Renault Dezir safely.warning-abs-Renault-Dezir

What is an ABS on a Renault Dezir

ABS means Anti Blocking System . It is a device which offers the possibility of improving the braking system, in particular during continuous braking. Before the creation of ABS, the brake pedal was directly linked to the pads. As soon as the pedal was depressed, the pads closed on the discs. The downside with this system is that there can be a risk of skating. With the help of sensors, ABS calculated the braking system. Instead of maintaining the discs, the pressure will oscillate several times in a very short time, in order to avoid a blocking total of Renault Dezir tires. No skating, and braking becomes more efficient.

Renault Dezir: why the ABS warning light is on

If the ABS warning light comes on, it is certain that this Renault Dezir has a problem. As with all other indicator lights, it is relatively common that it just concerns an electrical connection problem. That said, it's better to be sure.

False contact

Raise the lines of the ABS probes of this Renault Dezir and read the electrical current using a multimeter . Supposing that one of them does not have the same value as the others, it means that there is an electrical problem. Reassemble the line, if you find a bad connection it will have to be rectified. If ever a wire is in bad condition, it will have to be changed.

A sensor problem

This obviously remains a relatively common problem on a Renault Dezir. Your sonar may be sending an erroneous message. Therefore, it will suffice to change the sensor concerned. It is possible to check the sensors using a oscilloscope .

A problem with the hydraulic block

The ABS of this Renault Dezir operates using a device hydraulic , which gives the opportunity to manage the intensity of the brake pads. In the event that this device is defective, replacement of the ABS unit is usually compulsory. If this remains a problem of the block, it is usually felt when braking.

Conclusion

An ABS warning light that stays on can come from quite distinct causes. Either a sensor problem, an electrical fault. If your ABS unit is defective, it will probably have to be changed. And this intervention is rather expensive, on a Renault Dezir or on any type of car. It is essential not to abandon an ABS witness, for understandable safety reasons.
