Tech 1 Scan Tool
Used "Tech One" scan tools still seem to be selling for serious money -- I wonder if there is anything available in the form of laptop software and adapter that allows the same access to data over the vehicles GM data link connector -- My exact application is a 1994 (pre OBD II) 4.3 L V-6 and associated 4L60E -- Thanks for any suggestions

OTC Monitor 2000 with Pathfinder 1995 software cartridge and GM-II cable.. probably run $60 or so at most on Ebay

Tech 1 is ok, but it only works on GM. Other scan tools like the snap on mt 2500 work on most makes and models with appropriate cartridges, something the tech 1 cant pays to shop around.

Tech 1 is the only scanner that can do the GM ABS brake bleeds. If that is what the OP is looking to do. then the Tech 1 is the only solution. For everything else, there are a lot of cheaper alternatives for OBD-I

Thanks for all the advise! I have no need for ABS brake bleeds so I will refine my shopping into a price range that matches my finances more closely --

I agree that there are less expensive tools out there, particularly if you only care about OBD1 cars. I got an OTC Genisys since I also have OBD2 cars, but the OTC 2000 and 4000 units are available fairly inexpensively on ebay. The hardwired cartridges for these are also cheap since everyone with a Genisys now uses the CDs instead of the cartridges. The OTC tools are much better than the cheap code reading scan tools because they are bi-directional. The OTC tools can run tests in addition to just reading codes.

I have an OTC 2000 model scanner tucked away somewhere. I could let it go for a decent offer but I'll have to check - I think the Ford adapter was borrowed around 15-20 years ago and not returned. Either it or the Chrysler... Something to consider. Plus, it's setup for all makes up to whatever year I last updated it. It's, uhm, been awhile...
