What is ABS on a Smart Fortwo 3
ABS stands for Anti Blocking System . It is a mechanism that improves your braking, especially for sustained braking. Before the creation of ABS, the brake pedal was directly linked to the pads. As soon as the pedal was depressed, the pads tightened on the discs. The inconvenience with this mechanism is that there may be a chance of skating. With the help of sensors, ABS assesses the braking system. Instead of holding the discs, the pressure will decrease and then increase various times in a very short time, thus preventing a blocking total wheels of your Smart Fortwo 3. Not a single slip, and braking is much more efficient.

False contact
Follow the ABS probe cables of this Smart Fortwo 3 and measure the electric current with the help of a multimeter . If one of them does not have the same value as the others, it is because there is a false contact. Follow the cables, if you find a connection fault it is necessary to repair it. When a cable is damaged, it must be changed.
A sensor problem
This naturally remains a relatively common malfunction for a Smart Fortwo 3. It happens that your sensor sends an erroneous message. In this case, it will be enough to change the problematic sensor. You will be able to test the sensors using a oscilloscope .
A problem with the hydraulic block
The ABS of this Smart Fortwo 3 works using a system hydraulic , which will manage the force of the brake pads. In the event that this system is damaged, replacement of the ABS unit is often essential. If it remains a block malfunction, you can often feel it when you brake.
Conclusion
The ABS warning light that remains on can come from a variety of reasons. Whether it is a sensor malfunction, an electrical fault. If your ABS block is faulty, it is probably necessary to change it. And this intervention is relatively expensive, for a Smart Fortwo 3 or for any other car model. It is essential not to abandon an ABS warning light, for obvious safety reasons.
