I am currently looking to figure out why my Rear ABS light stays on. I am considering a OBD tool. and i was wondering is there a OBD 1 or 2 that is for a 1992 Ford Bronco fullsize w/ 5.0L 302 v-8? please help? i went to a schucks oreilly auto store and theyu told me i had to do it manually. i am wondering is there anything other than a manual way to get trouble codes without counting the flashes from the check engine light(which doesnt flash anyway or stays on) so i am confused what to do?
