Hi. The anti-lock braking system (ABS) is designed to pump the brake system for the driver in the event of a panic stop. This prevents wheel lock ups and helps maintain vehicle control. The ABS system uses a control module and speed sensors to determine the rate of deceleration. If the module determines that a wheel lockup is about to take place, it will pulse the hydraulic modulator. If the module determines there is a problem with the ABS system, or there is a problem with the module internally, the Check Engine Light will be illuminated. Since the problem could be anywhere in the system, I suggest you have a trained mechanic diagnose the ABS Light for you.
