I had to charge up the battery a few weeks ago due to not driving the car enough. I actually had to pop the frunk lid by doing the jumper cable trick.

The climate control unit will not work now. Thoughts?

Now that the battery is charged, disconnect the negative battery cable for 10 minutes and reconnect it. Don't latch the frunk out of habit.

Thanks Pete I was thinking of doing the same. Another trick would be to disconnect both pos and neg leads and attach them over night for a reset.

Disconnecting one is the same as disconnecting both as it stops the current flow. When I put my car back together recently I had connected the battery before installing the taillights to make sure I didn't have any shorts or arcing behind the alternator from the extension cable I made. Once I put everything back together, my reverse lights didn't work and I got that message on the dash. Removed and reinstalled the taillights with no change. Disconnected the battery for 10 minutes and the reverse lights came back and error went away. Pretty sure that will get you back in business.
