I had that happen to me twice. Both times the light dissapeared after having to jam on the brakes to do a hard stop.
I know it sounds silly, but find and empty road and try a hard stop from at least 30 or 40 mph. It may be that when the ABS gets activated, it resets the light.
( I dont know sh!t about brakes, sensors, ABS or any mechanical thing for that matter; I'm just telling you what happened to me. Maybe someone that knows better will chime in).
