Review on Efficiently Diagnose GM OBD1 Codes with INNOVA 3123 Code Reader by Scott Clayton

Revainrating 5 out of 5

Works perfectly on 1991 S10.

Works great on 1991 S10. Yes I know you can jump over two terminals and get the same results. I use this because the outlet is in an awkward location and my Clumsy recipe works well enough that I can jump over the wrong terminals and damage who knows what. The book is a bit confusing in the code section, but I found the code descriptions on the internet and later bought a Haynes manual that has consistent descriptions.

Pros
  • Works great for me
Cons
  • Some trouble
