        Does the scanner confirm connection to the PCM, and show all other data - just "no codes"? Did you pull power to the PCM before you connected the scanner?

          Yes it confirms everything. Shows all data or what ever you want to see.But when you get done checking codes. It says no trouble codes found. But the light will come on an stay on when you drive it.I guess I will take it to this place I go to an have them scan it an see what happens.

            If it were me, I would reset it and see if the light goes out. If there is a problem, the light will pop back on and you might get the code.
