I have a mint condition OTC 4000E (Enhanced) diagnostic scanner for use on OBD I GM, Ford & Chrysler vehicles.
This is the same tools that the GM Dealers and all of the Auto Maintenance Shops used to work on OBD I vehicles.
I’ve used this mostly on the 20+ Fieros that I’ve owned over the years, always with excellent results. Really takes the guesswork out of diagnosing problems. The cartridge and manual say it’s for up to model year 1990, but, it came with the supplement for 1991 and I, and other users have never had trouble using it on vehicles up to 1995. If you need cartridges for other years and/or auto makes they are plentiful on the internet. It comes with everything that you see in the pictures below, including the 3 cables for GM, Ford & Chrysler vehicles, large instruction manual, hard case and the software cartridge. It also comes with a Snap-On Tools Scan Gra-Fix software package that came with it. I never used it so I can’t really say much about it other than it is from Snap-On so is probably pretty good.
I don’t think you’ll find one of these in better condition than this set. The hard case has really helped to protect this stuff over the years. No cracked or dimpled keys, no scuffs or scratches, pretty much as new. Only has a few smudged fingerprints courtesy of friends that I have let use it over the years. They never seem to care for stuff as much as I do, but, they’re friends, so, you let it slide!!
The manual is very detailed and there are also dozens of great tutorials and tips on You Tube.
