The ABS warning light will blink on and off in a pattern, corresponding to a trouble code. The anti-lock braking (ABS) system is used to maintain wheel motion and traction while braking, accelerating or cornering on a slippery surface. Anti-lock braking systems are complex, and are typically diagnosed through professional computer scanning equipment, or manufacturer specific software.
