I have a clone bought years ago and love how well it works. Used it on many OBD2 vehicles like my 2008 Silverado to activate the power locks and diagnose a bad switch as well as a bad cruise control brake pedal switch that would randomly turn the cruise off when going over bumps. It's also great on OBD1 cars. Only issue was when I tried to scan my '91 Grand Am for a check engine light, it only went back to 1992 models. I entered it as a '92 anyway and it gave me the code for the EGR system, so not a big deal, but is 1992 the oldest year they are made for? Anybody still have a Tech1 scanner they still use and how well do they work? Older cars still have some modern systems like ABS and airbags and jumping wires at the diagnostic connector is primitive even when possible.
GM Tech2 scan tool, how far back does it go?

Looks like Tech2 was '92-13 and Tech1A was '83-95. I have never used a Tech1A only Tech2Win with an MDI clone.
Says 32meg when it turns on.
You should be able too see the model year ranges after the intro screen.
Tech 2 is 1992. Vetronix mastertech can run the tech 1 cartridges which is what I use or a Snapon scan tool. Autel does not support OBD I. Honestly, for ABS and airbag on a GM that early a scan tool doesnt get you much further than a paper clip at the ALDL does. There is very little live data available. Only thing I really remember needing a scan tool for on ABS or airbag on those was occasionally needing to do a motor home procedure on ABS 6 after a motor pack replacement
Well, mine has a dozen adapters to fit all the different makes' pre obd2 diagnostic ports.
yup and look in a menu and see if there is a vehicle older than 96 listed. The adapters are for early OBD II vehicles that had 2 DLCs, an OBD II and a proprietary and rest of world vehicles where OBD II wasnt a requirement. Im on my 5th Autel tool in the last 15 years and I am on the beta test team. There is no OBD I coverage, never has been and never will be
Ok I'll look.
I have the top of the line Autel tablet tool - amazing tool and I also have all those red adapters that I will never use. Regardless Autel - none of them - support OBD1
