Fault in rear a/c

[Danandbecky]

Good evening,
I have a 2020 377rlbh and have a "fault" in rear a/c unit when I use heat pump operation. The message says to check the owners manual, it seems to elude me?
Is there something I can verify/check out?
Thanks,
Dan

Our 2020 36FBTS had the fault last year, but have not noticed it since I updated the software and firmware.

Hi there! We are experiencing the same fault in our rear a/c while attempting to run heat pump. It appears to be a bit intermittent. Did you find a solution?! TIA

Mine is not intermittent, but some one suggested to update firmware and software.
