Default "Please check air conditioner connection" error

My GS350 is a spare car that sits for weeks at a time and recently the battery fully discharged. After charging the battery and getting it running, when I go to the climate control on the touchscreen, I don't get any climate controls. I get the error above. Does anyone know if there is a quick way for me to reset or rectify this or do I need to go to the dealer?

I guess my main question is whether anybody has heard of this error as a result of a dead battery. I searched the forum but didn't see anything to that effect.

Thanks.

People do it for brake jobs, ECUs, and AC systems reset.

So just to confirm all I have to do is touch these two with paper clip and it will clear it?
