well i got a 96 f-150, recently the abs light came on and wont go off, it turns on a minute or so after the trucks running, does anyone have a clue to the problem and does auto zone and them places do the analysis for that light or just the check engine light
oh and do they do them for the warning light that is on the end of the gear shift (overdrive light)

 

check the speed sensors on the front wheel hubs. they are magnetic and get metal debris stuck on them causing an error
