A light that is on is not necessarily a good sign. It's easy to believe that it's just a problem of sensors . However, it is essential to pay attention to it. What is ABS used for? Why does the light come on? what are the solutions? We will try to elucidate all these questions, in this way you will be able to drive this Renault Fregate safely.
What is ABS on a Renault Fregate
ABS stands for Anti Blocking System . It is a mechanism that improves the braking system, among other things during continuous braking. Before the development of ABS, the brake pedal was simply linked to the pads. As soon as the pedal was depressed, the pads tightened on the discs. The disadvantage with this system is that there may be a risk of slippage. With the help of sensors, ABS calculated the braking system. Instead of being pressed on the discs, the pressure will vary several times in a very short time, in order to prevent a blocking overview of the Renault Fregate wheels. No skidding, and braking becomes even more effective.
Renault Fregate: why the ABS warning light is on
If the ABS warning light remains on, there is no question that this Renault Fregate has a problem. As on all the other indicators, it is relatively usual that it concerns just a contact problem. However, it is better to be insured.
False contact
Follow the lines of the ABS probes of this Renault Fregate and take the electric voltage with a multimeter . If one of them does not have the same value as the others, it is because there is an electrical problem. Reassemble the wiring, if you discover a connection fault it is necessary to correct it. When a cable is in bad condition, it is necessary to change it.
A sensor problem
This is of course a relatively common problem for a Renault Fregate. It happens that your sonar sends an erroneous message. In this specific case, it will suffice to change the sounder concerned. You can check the sensors using a oscilloscope .
A problem with the hydraulic block
The ABS of this Renault Fregate works using a mechanism hydraulic , which will manage the force of the brake pads. In the event that this mechanism fails, replacement of the ABS unit is usually essential. If this is still a block problem, you can usually feel it when braking.
Conclusion
An ABS warning light that turns on can come from a variety of reasons. Whether it's a sonar problem, a false contact. If your ABS unit fails, it is probably necessary to change it. And this intervention is rather expensive, for a Renault Fregate or for any model of car. It is essential not to abandon an ABS warning light, for obvious safety reasons.
