    Default 98 silverado 350 no supported pids?

    Tried helping a friend diagnose a problem with his truck and I couldn't connect to it. I can read and reset trouble codes but that is all. It's a '98 silverado with 350. I assumed it would be an L31 98-00 Vortec.. I'm guessing its not?

    It works, I had one. In Scantool Connect and choose the L31 Vortec 98-00.

    I tried that about 10 times.. It never would let me pick any pids except external?
