How does the ABS system work on a car?

The ABS system is made up of the ABS module, and ABS sensors at each wheel. The sensors detect wheel speed, and will send a message to the ABS module to rapidly pump the brakes when it is detected that the vehicle is skidding or has lost traction.

What happens when an ABS wheel sensor fails?

Loss of Anti-lock Brakes When an ABS wheel sensor fails, it causes the anti-lock brakes to be inoperable. Anytime a fault is noticed, the system triggers an alert and the ABS warning light comes on. From here, the vehicle’s electronic control module stops receiving valuable data from the sensor.
