Does it flash out any error codes for checksum failure

Delco, I am new...very new...to tuning and using TunerPro. I did not notice any specific codes for checksum failure. There were NO flashing Codes. I checked by shorting Pins A & B on the ALDL. Would I see that in TunerPro?

Also, when you put the 28 pin ZIF socket in, did you solder pins 1,2, 26-28 together as seen in this picture?

damanx,

Yes, those were the pins that I soldered together.
