A warning light that goes off is not a great omen. It is easy to believe that it is only a malfunction arising from the sensors . However, it is important to pay attention to it. What is an ABS for? Why does the warning light go off? what are the solutions? We will answer all of these questions, so you can drive the smart smart safely.
What is an ABS on a smart smart
ABS stands for Anti Blocking System . It is a device which improves the braking system, in particular for sustained braking. Before the invention of ABS, the brake pedal was simply linked to the pads. When you depressed the pedal, the pads closed on the discs. The downside with this mechanism is that there may be a risk of slipping. Thanks to probes, the ABS assesses the braking system. Instead of holding the discs, the pressure will oscillate a number of times in a very short time, to avoid a blocking complete wheels of your smart smart. No skating, and braking becomes even more efficient.
smart smart: why the ABS warning light is on
If the ABS warning light is on, it is sure that your smart smart has a malfunction. As with all the other witnesses, it is quite common that this is only a contact malfunction. However, it's better to be sure.
False contact
Follow the lines of the ABS sounders of your smart smart and measure the electrical voltage with the help of a multimeter . When one of them does not have the same value as the others, there is an electrical problem. Reassemble the wiring, if you find a connection fault it is necessary to troubleshoot it. When a wire is in bad condition, it is necessary to change it.
A sensor problem
This is indeed a fairly common malfunction for a smart smart. It happens that your sensor sends an erroneous message. So it will be enough to change the problematic sonar. You can check the probes using a oscilloscope .
A problem with the hydraulic block
The ABS of your smart smart works using a mechanism hydraulic , which manages the pressure of the brake pads. In the event that this mechanism fails, replacement of the ABS unit is usually mandatory. In the event that this remains a malfunction of the block, it can often be felt when braking.
Conclusion
The ABS warning light that comes on can be caused by quite different causes. Whether it's a sonar malfunction, a bad contact. If your ABS unit is not functional, it is certainly necessary to change it. And this operation is relatively expensive, for a smart smart or for each model of vehicle. It is important not to neglect an ABS indicator, for obvious safety reasons. Leave a comment in case this special ABS warning light text helped you. See you soon!
