ok, so i was driving home tonight and i got on the brakes kinda hard. first my (parking) brake light came on, then my abs light came on. my brake light went away when i got off the brakes but the abs light stayed on. if i turn the truck off it goes away. i tried getting on the brakes again and it did the same thing. should any lights come on at all when i hit the brakes or is this something weird? any ideas?
