ABS sensor replacement
Has anyone replaced theirs, what's involved?
How can you tell which one is bad when Anti Lock light comes on?
Are they interchangeable or are they individual sensors ( i.e. front right, left rear etc. )

Re: ABS sensor replacement (joseph p)
No codes...checked, only Anti Lock light on!
Another way to find out if the wheel speed sensors are working (if there are no codes) is with the Vetronix Tech-1A scanner http://www.vetronix.com/diagnostics/tech1a/index.html with the "chassis" cartridge installed. With it, you can view the speed of all four wheels independently -- by looking at the speed of all four wheels along with the speed from the speedometer you can determine a faulty wheel speed sensor -- when driving down a straight road, all five readings should be the same.

Re: ABS sensor replacement (Tom Piper)
Tom,
The early 86-89 ABS systems did not have codes. It either works or it senses a fault and turns on the ABS light on the dash. I know, because I bought the official GM Kent-Moore ABS tester for 86-89 Corvettes as well as a used copy of the GM Corvette ABS Training video and tested my car myself after 3 dealers couldn't figure out what was wrong with my 88 ABS. I also checked this with Gordon Killebrew personally.
Even a Tech-1 cannot test the early 86-89 ABS for codes because the ABS controller doesn't hook up to a Body & Chassis controller. Some 90s and I believe all of the 91 & later versions of ABS have codes and can be scanned that way, but not 86-89.
Joseph P, if you will search the archives you will find several threads where I have posted extensive steps to use in checking for sensor and controller problems on the 86-89 ABS systems. Look for ABS and my forum id.
If you don't find the threads, feel free to email me directly and I'll be glad to send you a small write-up with static and dynamic checks you can use to troubleshoot your 89 ABS system.
