Mine comes on everytime I drive. It varies when it comes on. Last summer I looked at the wiring harness going to the ABS module, and it was rubbing up against something. I fixed that part of the wire, but it's shorting out still somewhere down the harness, and I haven't had time to disect the it. Also look at your abs sensor on the pumpkin/ends of the rear, they could have something that made them improperly read or not read the reluctor ring at all.

A few years before my harness started shorting, my light would come on just like it does now. Turns out metallic dust collected at the end of the prong reading the reluctor ring on the differential. It prevented it from getting a proper read, so I cleaned it off, and that fixed it.
