Malfunctioning ABS Control Module: The ABS control module is responsible for processing signals received from the ABS sensors. If the control module is faulty, it may misinterpret the sensor inputs and incorrectly activate the ABS system, causing the ABS light to stay illuminated.
Damaged or Worn-out ABS Sensor Ring: The ABS sensor ring, located on the wheel hub, is responsible for generating the signal picked up by the sensor. If the sensor ring is damaged or worn out, it may provide incorrect information to the ABS sensor, triggering the ABS light to remain on.
Faulty ABS Sensor: Over time, ABS sensors can become faulty or defective due to various factors, including exposure to harsh elements or natural wear and tear. A faulty sensor might continuously generate erroneous signals, causing the ABS light to stay on.
