What is an ABS on a Citroen Visa

ABS stands for Anti Blocking System . It is a device which will make it possible to improve the braking system, among other things for intensive braking. Before the invention of ABS, the brake pedal was directly linked to the pads. When the pedal was depressed, the pads tightened on the discs. The downside with this device is that there may be a chance of skating. With the help of sensors, ABS assesses braking. Instead of staying pressed on the discs, the pressure will vary a number of times in a very short time, thus preventing a blocking complete wheels of your Citroen Visa. Not a single skate, and braking becomes much more efficient.

Citroen Visa: why the ABS warning light is on

If the ABS warning light ever comes on, there is no doubt that the Citroen Visa has a malfunction. As with all the other witnesses, it is relatively common that it simply concerns a contact malfunction. However, it's better to be sure.

False contact

Follow the cables of the ABS probes of the Citroen Visa and take the electric intensity with a multimeter . In the event that one of them does not hold the same value as the other three, it means that there is an electrical fault. Follow the wiring, if you find a connection fault you will have to repair it. If ever a wire is damaged, it will have to be replaced.

A sensor problem

This is obviously a relatively common malfunction for a Citroen Visa. The sensor may be sending the wrong message. Then just replace the problematic sonar. You will be able to check the sensors using a oscilloscope .

A problem with the hydraulic block

The ABS of the Citroen Visa works using a mechanism hydraulic , which gives the opportunity to manage the intensity of the brake pads. In the event that this mechanism fails, changing the ABS block is usually necessary. If it remains a block malfunction, it is generally felt when braking.

Conclusion

The ABS warning light that comes on can come from quite distinct causes. Whether it is a sonar malfunction, a false contact. If the ABS unit is not functional, it will certainly have to be changed. And this intervention is rather expensive, for a Citroen Visa or for any car model. It is important not to neglect an ABS witness, for obvious safety reasons.
