Anti-Lock/Anti-Skid Brake System (ABS) Warning Light


The Anti-Lock Braking System or Anti-Skid Braking System (ABS) is an automobile safety system that allows the wheels on a motor vehicle to maintain tractive contact with the road surface according to driver inputs while braking, preventing the wheels from locking up (ceasing rotation) and avoiding uncontrolled skidding. It is an automated system that uses the principles of threshold braking and cadence braking which were practiced by skillful drivers with previous generation braking systems. It does this at a much faster rate and with better control than a driver could manage.

Possible causes

The ABS warning light is set when there is a mechanical or electronic problem with the ABS System. The most common problem that may trigger the "Anti-Lock/Anti-Skid Brake System (ABS) Warning Light" are:
