A triggering witness is not necessarily a good sign. We can believe that it is just a dysfunction coming from sensors . However, it is essential to pay attention to it. What is the role of ABS? Why does the light go on? What should be done? We will try to elucidate all of these questions, so that you can drive your Citroen Nemo with confidence.LED-abs-Citroen Nemo

What is ABS on a Citroen Nemo

ABS stands for Anti Blocking System . It is a system that improves the braking system, especially during intensive braking. Before the development of ABS, the brake pedal was simply linked to the pads. When the pedal was depressed, the pads sticked to the discs. The inconvenience with this system is that there may be a risk of slippage. Using probes, ABS assesses the braking system. Instead of staying pressed on the discs, the pressure will vary several times in a very short time, which avoids a blocking complete wheels of the Citroen Nemo. Not a single skid, and braking becomes more efficient.

Citroen Nemo: why the ABS warning light is on

If the ABS warning light is on, it is sure that your Citroen Nemo has a malfunction. As with all of the other indicator lights, it is relatively common for this to be just an electrical connection malfunction. However, it's better to be sure.

False contact

Reassemble the ABS probe lines of your Citroen Nemo and measure the electrical current with a multimeter . Supposing that one of them does not have the same value as the other three, it means that there is a false contact. Follow the cables, if you find a connection fault you will have to troubleshoot it. When a wire is damaged, you will have to change it.

A sensor problem

This is of course a relatively common malfunction for a Citroen Nemo. It happens that your detector emits an erroneous message. So it will be enough to change the problematic sonar. You will be able to check the probes using a oscilloscope .

A problem with the hydraulic block

The ABS of your Citroen Nemo works using a mechanism hydraulic , which gives the opportunity to manage the pressure of the brake pads. If this mechanism fails, changing the ABS unit is generally essential. If it is a block malfunction, it usually feels when braking.

Conclusion

An ABS warning light that comes on can come from quite different causes. Whether it is a sonar malfunction, an electrical fault. If your ABS unit is damaged, you will certainly have to change it. And this intervention is rather expensive, for a Citroen Nemo or for any car model. It is essential not to abandon an ABS warning light, for understandable safety reasons.
