The scan tools at AutoZone cannot access the ABS systems, but even if they could, if there is a hard fault, clearing the code will only turn off the light for a very short time. As soon as the ABS computer recognizes the problem is still present, the light will come back on.

As for the benefit of ABS, try stopping quicker/shorter without ABS on a wet or sandy or snowy surface than with ABS. To make things even more interesting, try steering around an obstacle while braking with and without ABS. The ABS pump modulates the brakes tens to hundreds of times per second. That's a lot faster than any person can do that. ABS brakes makes the average driver (and even most above average drivers) more able to stop and steer in a panic situation than without, which makes everyone on the roads safer.
