Chad - actually, you can't do ANY of these things with a Tech II, except for the driver greeting.
really I read some where that you could adjust the
powersteering and greeting display.
now I assumed
that cuz it had bi-dirctional data control, and could write information to the PCM, that it could do thoes other things. Ive never seen/owned/operated a gm tech 2. just making a guess.
I figured for that price that tool would wash the car also.
I stand corrected
