Wird issue this morning RPM / AP

Hello all!!!!
I had really weird issue this morning with My Pu.
So i connect my AP and start the car, everything sounds good as far as engine noise, but my RPM needle is bouncing between 0RPM - 2000RPM, engine is at steady RPM it is just needle that is bouncing. Next i notice that my AP is unable to connect to the car, and traction control light is on. I shut the car down and give my buddy Keith a call. After some troubleshooting he tells me to check if there is an update for AP. Sooooo i check and sure enough there is:)
I updated AP and and proceeded to start the car. This time car starts just like before and RPM needle doesn't just like bunny on crack, and AP was able to connect to the car, but traction control light is on.
After checking codes i came up with following:
PCM - no description available
U0073 - Control Module Comm. Bus Off

I cleared the codes and drove like 5 miles and they did not came back…..

Can any one chime in and shine some light on this?

this is my 2nd 3rd 4th gear WOT

Your battery was probably on its last limb.

Check fuses as well. Interior fuse box

Check to make sure any connectors around the ecu are fully seated.

And i checked codes, well Keith checked for me and it looks like it was low voltage / high voltage…..
