On the schematics for the truck, it shows "C1, C2, C3" for the PCM. I take this to mean connecotr #, then the pin #'s and wire colors.

On the connectors that actually plug into the PCM, it shows A, B, C. Am I missing something?

Ok lets go back to square 1

What is AA 00 ? Manual shows to be "PCM messages not received" - refer to appropriate diagnostic information.
This is a C-code in case it helps.

Where do I go from here?

We replaced the PCM and the trucks runs.
Bought a rebuilt PCM online for $180.
