I keep getting an error after shutting my truck off in my tuner about a communication error.
Has not always been this way.
2014 with G56.
Does anyone else have this issue, or can you fix it?
I appreciate any help you can provide.

Have you unplugged and re-plugged all of the connections to try and reset?
I got that message when my MM3 was not firing right when I started my truck (it would take a minute or so before coming on), and I would tap the screen to try and get it to come on - I would get the error.
Unplugging seemed to fix my problem.
It's the same issue for the last nine months but infrequent, and I didn't think much of it.
I bought a new Suncoast Transmission 68RFE guardian, and I can't communicate with TCM via the Snap-on tool.
Thinking there might be a corrupted file.
