It could be two things:
1. Wheel sensors. (Most common) 2. OVP relay.

Has the light come on, and stayed on? If it goes out (after a re-start) and then comes back on after a tap or 4 of the brakes, it could also be the brake light switch (stop lamp switch).
Best thing, would be to check for codes.

First suspect would be fuse on top of OVP....

Not so much that the part is a nickle, but that system feed power is always a first check on todays cars b/c so much of their operation is electronic dependant.. I see so many parts get changed before verifying the fuse or fuse connection....I guess people just expect the worst from the get-go....

The light goes off after restart, then if I get on the brakes the ABS freaks out then the light comes on. By freaks out, I mean pushes the pedal back and removes braking power.
I just checked, the brake lights work properly. The fuse box is 100%, but I am not sure where this OVP is. I never replace parts until I have clear indication and trouble shooting...

I would first clean the ABS sensors on both front wheels.
