Well, I finally got Tune to read my PCM. I was beginning to think that my PCM was #65,535 out of all the possible combinations. After over an hour of attempts, I realized the "Preparing PCM for reading flash..." light didn't mean anything. I did a series of stops and starts and I finally saw the "PCM not ready, waiting light" and then it started to log and gave a time to go and the bar started to move.
As the book says, I have several DTCs, low voltage and Reduced engine Power. I went to Scan and under Info deleted the DTCs but after they're all cleared and I disconnect and turn the key off, they come back. I've cleared them several times and the DIC (MIL) still gives the same two (above) codes.
Would someone please give me a clue on what I'm missing here.
I've swallowed my pride and expanded on the above so that my experience will maybe help others new to this operation.

Thanks, Curt
