Review on Efficiently Diagnose GM OBD1 Codes with INNOVA 3123 Code Reader by Peter Nobles

Revainrating 4 out of 5

You received the update before you even read it

It says all instructions must be repaired before you can use it. It actually says you fixed it before I can tell you what's wrong with it! My truck wouldn't start, I just flashed 12 1212 1212 which means it's in good condition and ready to go. I fixed it, put it back on her, and you know what it said? 12. They built the damn thing for a reason that I think would be good for some applications but not for me. However, it looks great gathering dust in my toolbox! See picture above
