I had the same problem last year (spring 2014) and after reading this forum I figured the ABS sensor must have had some moisture or corrosion in it. I decided to tackle the problem myself with good results. Be aware that I am NOT a mechanic and I can't even raise my vehicle off the ground, but I managed to get rid of the issue.

I laid down underneath the car with a can of WD-40 and sprayed a LOT of it in the area of the ABS sensors. I did this on all 4 wheels. It's not easy to get in there but I managed to soak all the sensors as much as possible hoping the WD-40 would soak in the small gaps where the contacts are.

It didn't work right away, but probably within a week the ABS light and the brake warning light went off. It came back on for a brief period then went off again. It's been about a year and the light hasn't come back on. I intend to spray it again with WD-40 later this spring for preventive maintenance. This may or may not work for you, but it worked for me. Good luck.

Mine also cycled on and off for a long period until I attempted to pull the plug off for inspection and likely doing permanent damage as the light stay on constantly now. Solution = install new rear wheel bearing (with ABS) and possibly also the wiring harness. OR drive with the warning lights on and no ABS.
