The first thing I would recommend is to have the PCM updated to see if that changes things.
Pics 1 and 2 are the descriptions. Based on what I'm reading for diagnostics, I would first focus on the P061D code. Between these two codes, you are going to have a hundred pages of diagnostics. LOL However, I will let that up to you.
I suggested that code because it is tied to the PCM. The other code is likely a wiring issue that in fact, may be caused by the PCM. I don't know if that makes sense or not. Regardless, let me know which way you would like to run with this, and I'll get you set up with the diagnostics.
