Did you check the wire/harness connecting the abs sensor for damage? My lights are on due to a damaged wire inside the harness.

It's one of your tire pressure sensors.

ok how do you check tire pressure sensors? does swaping tires around help?

Easy/Stupid question, but have you checked pressure and aired-up all of your tires? I had the low tire pressure light come on and disregarded it, thinking it was on because of how cold it was outside. After a couple of days the VSC TRAC Off lights came on - all it took was getting my tires up to correct pressure and they went away. Have also read where it can be due to a loose gas cap - doesn't sound like you're getting that code though. If that simple fix doesn't work, you'll probably need to look into what ebg18t suggested.
