A light that lights up is not necessarily a good sign. You may believe that this is simply a problem related to sensors . However, it is important to pay attention to it. What is the role of ABS? Why is the light on? what are the solutions? We will answer these questions, so you will be able to get behind the wheel of this Citroen Survolt safely.warning-abs-Citroen-Survolt

What is ABS on a Citroen Survolt

ABS means Anti Blocking System . It is a mechanism that improves your braking, among other things during intensive braking. Before the development of ABS, the brake pedal was simply linked to the pads. As soon as you pressed, the pads closed on the discs. The trouble with this device is that there is a risk of skating. With the help of probes, ABS calculated the braking system. Instead of holding the discs, the pressure will vary various times in a very short time, thus preventing a blocking overall tire size for the Citroen Survolt. No skating, and braking is even more efficient.

Citroen Survolt: why the ABS warning light is on

If the ABS warning light remains on, it is sure that your Citroen Survolt has a problem. As with all the other indicator lights, it is quite common that this simply concerns an electrical connection problem. That said, it is better to be certain.

False contact

Reassemble the ABS probe cables of your Citroen Survolt and measure the electrical voltage with a multimeter . When one of them does not have the same value as the others, it means that there is an electrical fault. Reassemble the line, if you find a connection fault you must resolve it. When a wire is damaged, it must be replaced.

A sensor problem

This is naturally a fairly common problem on a Citroen Survolt. The sonar may be sending the wrong message. In this situation, it will suffice to replace the problematic sensor. You can check the probes with a oscilloscope .

A problem with the hydraulic block

The ABS of your Citroen Survolt works thanks to a device hydraulic , which allows you to manage the intensity of the brake pads. In the event that this device fails, changing the ABS unit is often essential. If this remains a block problem, you can usually feel it when braking.

Conclusion

The ABS warning light that comes on can come from very distinct causes. Whether it's a sensor problem, an electrical fault. In case the ABS unit is defective, it should probably be changed. And this intervention happens to be relatively expensive, on a Citroen Survolt or on each car model. It is important not to neglect an ABS witness, for obvious safety reasons.
