What Does the ABS Light Indicate and What Causes It to Appear?


Posted April 20, 2022 by sikandar

To avoid a failed MOT test, check your car's MOT status and have an illuminated ABS light investigated and necessary repairs made.

 
The ABS light illuminates when there are problems with the anti-lock braking system. Low brake fluid, a blown fuse, or irregular data from wheel sensors are all possible causes.
The dashboard lights are supposed to alert you when anything is wrong with your car. When the ABS light illuminates, you may be concerned that the car is no longer safe to drive. The only way to know for sure is to figure out what's wrong with the vehicle that's creating the problem in the first place. You need answers before you get back in your vehicle.
The ABS light's meaning is explained in this guide. We also look at what's causing. Finally, you'll be able to determine if it's safe to drive with this light on.
Any warning dashboard lights that are illuminated might result in a failed MOT, so double-check your MOT status and the issues repaired.
The ABS Light's Causes
The ABS light is illuminated as a result of the following six issues:
1. Bad Speed Sensor - The wheel speed sensor measures the pace at which the wheels move and transmits that information to the ECU. The ECU can utilise this information to determine how to employ the ABS. If the ECU detects that one of the wheels is travelling faster than the others, it will release more brake fluid, allowing the wheel to slow down and boost traction on the road. A failed MOT will be caused by a defective wheel speed sensor, therefore check MOT status of your car, and get the damaged wheel speed sensors replaced by a trained mechanic.The ECU will not have reliable data if the speed sensor fails. Not only will the ABS light illuminate, but you should also be aware that slamming on the brakes might cause the car to lose traction. The traction control light may also illuminate. The speed sensor is situated quite close to the wheels in order to measure their speed. It suffers a great deal of damage as a result of its proximity to the brakes and exposure to the extreme heat. It can also be harmed by metal shavings or debris ejected by the brakes.
