that sucks, battery unhooked wont clear it, its pass or fail as you drive off or fire it up.
good news is my hub changed seems to have cleared up my issues. all but a bout 3 hours after i changed it, i went to the rehab my mom is in, like a fool used the free valet parking. same kid who took it from me picked it up, i notice hes driving at a snails passe and then gets to me finally and see the dash lit up like a x mass tree. as im getting into a car he just dragged to me cause the brakes were locked up when it fails sometimes and hes looking for a tip, go F your self kid. you were within shouting distant like 50 feet away, sir! your car wont roll. nothing. so he got nothing but a see ya.
good thing is i turned it off and re started it up and it drove off fine and the light has not come back on since. (3 days deep and counting) and ive tried to get to to go off, a few hard stops, start it roll a bit, pass the self test, turn it off do it over and over, it keeps passing. so far, so good.
id love to know wtf that dumb kid did to my car tho.
