I believe I found the problem. Last night the light came on again. When I got home from work, I turned the car off then back on. The light still came on. So I popped the hood and unlatched the main connection on the ABS motor. Of course, the light stayed on. So I reattached the connection and turned the ignition off, then back on about 10 seconds later. The light came on for a second like it's supposed to then turned off. So I pulled the connector out a little, as much as the little clip would allow without actually unlatching, probably only a millimeter or so. I looked on the dash, sure enough, the light came back on. I pushed it back in, turned the ignition off (it seems if the light is triggered, it will stay on, even if the problem is fixed. It seems only to reset if the ignition is turned off then back on.) Anyway, turned the ignition off, then back on. Light is off. I'm assuming a slighly offset or dirty connection. I cleaned both the contacts out with electrical cleaner. I'll see if it come's back. Thanks for the tips!
