PCM Fried?

I was driving back and realized my lights were really dim and the battery signal came on so I pulled my tuner up to measure voltage and it was running on 6.9V. As soon as I pulled up to park it started to throw bad voltage codes for different systems(P0562,P0046,P0528). I believe the PCM is fried or has a short of some sorts but I am at my whits end with this problem. Any thoughts on the subject?

Click my username and find the thread i started called ecu lockout.

I had something similar to this happen and it was the battery terminals shorting out, causing a surge to the connection box under the cab, which shut down all of the modules to save them. My truck wouldn't run unless codes were deleted, and when i did that, my security light popped on and it froze up my tuner so i couldn't read codes or delete codes or do anything. I couldn't load recovery files. After 2 months of sending SCT my pcm,tcm and tuner back and forth, i decided to have my truck towed to Innovative Diesel in MD who figured out my battery terminal was bad.

I forget the codes it was throwing.
