Try diconnecting the battery for a minute or so, then reconnect it. the computer should reset itself, and hopefully the light will go out.

SOURCE: what would cause the fault
It is most likely the abs sensor is dirty or bad,It won't affect the operation but it will prevent the abs feature from working.You can have it checked at any brake shop.Some will even do it for free.

I WOULD NOT KEEP DRIVING IT.WHEN ABS LIGHTS AND BRAKE LIGHTS COME ON.YOU HAVE BRAKE FAILURE. TOW IT TO DEALERSHIP HAVE IT SERVICE.AND CHECK THE ABS BRAKES SYSTEM .BECAUSE ABS BRAKE SYSTEM IS NOT A HOME FIX.BECAUSE THE ABS HYDRAULIC MODULATOR UNIT HAS LOWER FROM HOME POSITION .IN ORDER TO MOVE THE MASTER CYLINDER FROM UNIT.YOU NEED A TECH 2 SCANNER TO DO THE JOB.TO GET ABS BRAKES TO BLEED RIGHT BEST TO GET THEM PRESSURE BLEED INSTEAD OF MANUAL BLEEDING GET LESS AIR IN SYSTEM.THAT WHY SEE DEALER SHIP HAS THE THINGS TO DO THE JOB.
