An indicator light that is on is not necessarily a good sign. It is easy to believe that this is simply a problem from sensors . However, it is essential to pay attention to it. What is the role of ABS? Why does the indicator light come on? What to do? We will answer these questions, so you can get behind the wheel of this Volkswagen Jetta safely.
What is ABS on a Volkswagen Jetta
ABS means Anti Blocking System . It is a mechanism that improves the braking system, among other things during continuous braking. Before the development of ABS, the brake pedal was directly linked to the pads. When pressed, the pads stick to the discs. The disadvantage with this device is that there may be a risk of slipping. Thanks to sensors, ABS assesses braking. Instead of maintaining the discs, the pressure will decrease and then increase various times in a very short time, which avoids a blocking total wheels of the Volkswagen Jetta. No skidding, and braking is much more efficient.
Volkswagen Jetta: why the ABS warning light is on
When the ABS warning light remains on, it is certain that this Volkswagen Jetta has a problem. As with all of the other witnesses, it is relatively common for this to be simply an electrical connection problem. However, it is better to be sure.
False contact
Follow the wiring of the ABS sounders of this Volkswagen Jetta and read the electric current with the help of a multimeter . If one of them does not hold the same value as the other three, there is an electrical problem. Follow the cables, if you discover a connection fault you will have to troubleshoot it. When a cable is damaged, it will have to be changed.
A sensor problem
This of course remains a relatively common problem for a Volkswagen Jetta. Your sensor may issue an erroneous message. Therefore, it will suffice to change the problematic sonar. You can control the sensors using a oscilloscope .
A problem with the hydraulic block
The ABS of this Volkswagen Jetta operates using a device hydraulic , which provides an opportunity to manage the strength of the brake pads. In the event that this device is deficient, replacement of the ABS block is generally compulsory. When this remains a problem with the block, you can usually feel it when you brake.
Conclusion
The ABS warning light that comes on can come from many different reasons. Either a sonar problem, a false contact. Assuming that your ABS unit has failed, it will certainly have to be changed. And this intervention is quite expensive, for a Volkswagen Jetta or for any other model of car. It is essential not to neglect an ABS witness, for obvious security reasons. Do not hesitate to leave a comment if this specific ABS warning light article has ever been useful. Good road!
