Alright I just bought a 94 LS about a month ago. When I bought it the ABS light was on, couldnt figure out why? The car has a clean title, and one owner who did all the maintenance work on it. Also Im hearing a faint vibrating or humming noise when shifting from second to third. It only happens inbetween those gears, and it comes and goes. Any suggestions?

 

You can pull the ABS codes in the same manner as you pull a CEL.

 

Does ABS work?
Have you checked the ABS fuse?
Have you tried an ECU/ECM reset?

As mentioned, pull ABS trouble code. 94

 

Thanks both! Ya shortly after posting this I read the how to thread on pulling ABS codes. So I will check that out.
