An autoxray code scout will work nicely provided you have the GM specific cable with it. Problem with the OBD 1.5 or [email protected]#$(*d versions is it is a obd 1 system with an obd 2 port. When you plug in a standard obd 2 scanner, it thinks it is talking to an obd2 system and not the obd1. In my case, the code readers I used at Autozone and O'Reiley's kepy saying, "Unable to establish Communications." I ended up getting an Tech 1 code scanner from ebay to read and diagnose my system. Came in real handy troubleshooting my ABS system. I still have the autoxray code scout to help out other people needing one.

So did you have to piece your scanner together? Or did you buy it all together?

I found the Tech1 using allofcraigslist.com and asked the guy to put it on ebay for mutual buyer/seller protection and avoid the paranoia of CL scams. I was fortunate that the Tech 1 came with the Mass Storage Cartridge which diagnoses Powertrain, Transmission and ABS along with SIR (airbag) systems. I think it goes up to 1999 models. It works on my '95 so I am happy.

I had to buy separate cables and an adapter to diagnose the ABS system. The 16/12 adapter was $105 alone. Altogether it came to about $700.00 for the set but since I plan on keeping my blazer for a long time, I didn't mind spending the money. Add in the Factory Service manual and you can do damn near anything.

The thing about buying the separate cables was it was sold with Isuzu adapters and another cable I have no use for.

I play around with it from time to time. I can see while my blazer is running oil pressure, manifold intake air temperature, water temp, ignition timing and several other things that standard code readers won't show. With a push of a button, I can idle up or down.

Do an ebay search for tech1 and you get several results.

Parts list numbers are for the things I use

Tech1
Mass Storage cartridge p/n 3000003
GM 16/12 pin adapter P/N 02001574
adapter for testing ABS P/N TA02659
Cable P/N TA00011B
14/12 pin adapter P/N 3000086
Tech 1 OBD2 interface module P/N 3000091
16/24 pin cable adapter P/N 3000081

I tried this on mine, but it doesn't works. I have pins 4 and 5, not 3 and 4.

An actron code scout will do the trick nicely if you have the GM specific cable. I upgraded to a Mastertech and have my older tech1A in a box. Both work great.

I see far too many hillbilly redneck fixes in this forum for my liking. Take care of your blazer and it will take care of you.

I know this is an old thread but maybe this will help someone out. The Actron CP9145 will work on OBD 1.5 . I have one that works great and it has the OBD 2 style 16 pin cable. Only drawback is it won't do ABS or Airbags. It was pretty reasonable a couple of years ago. I got one from Amazon for $135. Hope this helps.
