A light that is on is by no means an excellent omen. It is easy to believe that it is simply a concern related to sensors . However, it is wiser to pay attention to it. What is the role of ABS? Why is the light on? what are the solutions? We will try to elucidate these questions, so that you can drive the Citroen Picasso safely.warning-abs-Citroen-Picasso

What is ABS on a Citroen Picasso

ABS stands for Anti Blocking System . It is a device which will make it possible to improve the braking system, inter alia during sustained braking. Before the invention of ABS, the brake pedal was simply connected to the pads. As soon as you step on the pedal, the pads stick to the discs. The downside with this mechanism is that there can be a chance of slipping. With the help of probes, ABS assesses the braking system. Instead of pressing on the discs, the pressure will decrease and then increase various times per second, to avoid a blocking complete wheels of the Citroen Picasso. No skidding, and braking is much more efficient.

Citroen Picasso: why the ABS warning light is on

In the event that the ABS warning light is on, there is no question that this Citroen Picasso has a problem. As on all the other indicators, it is rather common that it simply concerns a problem of electrical connection. However, it is better to be insured.

False contact

Follow the ABS sensor cables of this Citroen Picasso and read the electric current using a multimeter . If one of them does not have the same value as the other three, then there is an electrical fault. Follow the line, if you find a connection fault you must correct it. If ever a cable is in bad condition, it must be changed.

A sensor problem

This is of course a rather common concern for a Citroen Picasso. Sometimes the sensor sends the wrong message. In this specific case, it will suffice to change the sounder concerned. You will be able to test the probes using a oscilloscope .

A problem with the hydraulic block

The ABS of this Citroen Picasso works thanks to a mechanism hydraulic , which will manage the intensity of the brake pads. In the event that this mechanism is deficient, replacement of the ABS block is usually mandatory. In the event that it is a block issue, it is often felt when braking.

Conclusion

An ABS warning light that can be triggered can come from very different reasons. Whether it's a sonar problem, an electrical fault. Assuming the ABS unit has failed, it may need to be replaced. And this operation is quite expensive, for a Citroen Picasso or for each vehicle model. It is wiser not to abandon an ABS witness, for obvious security reasons.
