A light that is on is never a good omen. One can think that it is quite simply a concern stemming from sensors . However, it is wiser to pay attention to it. What is the role of ABS? Why does the light come on? What should be done? We will try to elucidate all these questions, so that you can drive and be Smart For-us safely.indicator-abs-Smart-For-us

What is ABS on a Smart For-us

ABS means Anti Blocking System . It is a system that offers the possibility of improving braking, among other things for sustained braking. Before the creation of ABS, the brake pedal was directly linked to the pads. When pressed, the pads tightened on the discs. The trouble with this device is that there is a chance of slippage. With the help of sensors, ABS assesses braking. Instead of leaning on the discs, the pressure will oscillate several times in a very short time, in order to prevent a blocking total of Smart For-us wheels. No skidding, and braking is much more effective.

Smart For-us: why the ABS warning light is on

If the ABS warning light comes on, there is no question that this Smart For-us has a problem. As with all other LEDs, it is quite common for this to be simply a concern for contact. However, it's better to be sure.

False contact

Reassemble the ABS sensor wiring for this Smart For-us and read the electrical current with a multimeter . If one of them does not have the same value as the other three, then there is an electrical fault. Follow the wiring, if you find a bad connection you will have to correct it. If a wire is in bad condition, it will have to be changed.

A sensor problem

This obviously remains a fairly common concern for a Smart For-us. Sometimes the detector sends the wrong message. Then, it will be enough to change the sensor concerned. You can test the sensors using a oscilloscope .

A problem with the hydraulic block

The ABS of this Smart For-us works using a mechanism hydraulic , which gives the opportunity to manage the pressure of the brake pads. When this mechanism is deficient, replacement of the ABS block is usually necessary. In the event that it is a block issue, it is generally felt when braking.

Conclusion

An ABS warning light that comes on can come from very distinct causes. Either a sensor problem, an electrical fault. If the ABS unit is ever defective, it will certainly have to be replaced. And this operation is quite expensive, for a Smart For-us or for any other car model. It is wiser not to abandon an ABS witness, for understandable safety reasons.
