An indicator that lights up is not necessarily an excellent omen. One can think that it is quite simply a concern stemming from sensors . That said, it's wiser to pay attention to it. What is the role of ABS? Why is the light on? What to do? We will try to elucidate these questions, so that you can drive the Hyundai Ioniq with confidence.
What is ABS on a Hyundai Ioniq
ABS stands for Anti Blocking System . It is a system that improves your braking, among other things during sustained brake applications. Before the invention of ABS, the brake pedal was directly linked to the pads. When pressed, the pads stick to the discs. The downside with this system is that there is a risk of slipping. With the help of probes, ABS assesses braking. Instead of holding the discs, the pressure will vary a number of times per second, which will prevent a blocking total wheels of your Hyundai Ioniq. Not a single skid, and braking is more efficient.
Hyundai Ioniq: why the ABS warning light is on
If the ABS warning light comes on, there is no doubt that your Hyundai Ioniq has a problem. As with all of the other witnesses, it is quite usual for this to be simply a problem with the electrical connection. That said, it is better to be assured.
False contact
Reassemble the ABS sensor cables of your Hyundai Ioniq and take the electrical voltage using a multimeter . If one of them does not have the same value as the other three, it is because there is a false contact. Reassemble the line, if you discover a bad connection it will have to be rectified. When a wire is damaged, it will have to be changed.
A sensor problem
This is of course a fairly common concern for a Hyundai Ioniq. It happens that your sensor sends an erroneous message. In this case, it will suffice to change the sonar in question. You can control the probes using a oscilloscope .
A problem with the hydraulic block
The ABS of your Hyundai Ioniq works using a system hydraulic , which gives the opportunity to manage the intensity of the brake pads. In the event that this system fails, changing the ABS block is often essential. In case this remains a concern of the block, we can usually feel it when braking.
Conclusion
The ABS warning light that comes on can come from quite different reasons. Whether it's a sonar problem, a false contact. If your ABS unit is faulty, it will probably have to be replaced. And this intervention happens to be relatively expensive, for a Hyundai Ioniq or for each vehicle model. It is wiser not to neglect an ABS witness, for obvious safety reasons.
