What is ABS on a Kia Optima 2 Sw

ABS means Anti Blocking System . It is a system that allows you to improve your braking, especially during continuous braking. Before the invention of ABS, the brake pedal was simply tied to the pads. When you pressed, the pads closed on the discs. The downside with this device is that there is a chance of skidding. Thanks to sensors, the ABS calculated the braking system. Instead of staying pressed on the discs, the pressure will decrease and then increase a certain number of times in a very short time, in order to avoid a blocking complete the wheels of the Kia Optima 2 Sw. Not a single skid, and braking becomes more efficient.

Kia Optima 2 Sw: why the ABS warning light is on

If the ABS warning light comes on, it is certain that the Kia Optima 2 Sw has a malfunction. As with all of the other LEDs, it is relatively common that it is simply an electrical connection malfunction. However, you better be sure.

False contact

Follow the cables of the ABS sensors of the Kia Optima 2 Sw and take the electrical intensity with a multimeter . If one of them does not have the same value as the other three, there is an electrical fault. Go back up the line, if you find a connection fault you will have to rectify it. If a cable is damaged, you will have to change it.

A sensor problem

This is obviously a relatively frequent malfunction for a Kia Optima 2 Sw. It happens that the detector sends an incorrect message. So, it will suffice to change the sensor in question. You can control the sensors using a oscilloscope .

A problem with the hydraulic block

The ABS of the Kia Optima 2 Sw works using a mechanism hydraulic , which will make it possible to manage the force of the brake pads. In the event that this mechanism fails, replacement of the ABS unit is generally necessary. If it's a block malfunction, you can usually feel it when braking.

Conclusion

An ABS warning light that comes on can come from quite distinct causes. Either a sensor malfunction, an electrical fault. If the ABS unit is damaged, you may need to replace it. And this intervention is quite expensive, for a Kia Optima 2 Sw or for each car model. It is essential not to neglect an ABS warning light, for obvious safety reasons.
