Thanks for redirecting me in the right direction. I was able to resolve this issue.
I initially tried unplugged the OBD cable from the harness but was seeing the same A/C issue.
Then I just swapped out the USB long cable with another (shorter) one that I had at home. Everything seems to be...
Without Comma plugged in, there are no errors and everything seems normal other than A/C doesn’t ever kick on.
I did one other experiment, which is to also unplug just the coupler (and short cable). In this case, I get all the errors!
One thing I haven’t tried is to unplug the OBD2 cable...
I’ve tried reinserting the cables and I am inserting them such that they give that very satisfying click.
The weird thing about my situation is that everything behaves normally when C4 is docked/installed. No errors from car, A/C works normally. It’s just that for the shorter drives where I...
This is definitely not the case as I have the coupler hooked up lightning bolt to long cable and comma to short cable.

Has anyone else experience this?
