You indicated that your Soul is a 2014 model. Yes, it has a heat pump - all of the EV Souls sold since 2014 have had that option; however, the portion of SA427 that applies to the FATC (the portion that affects the climate control and heat pump system) appears to apply only to certain 2016 and 2017 model year vehicles. This is indicated the in ROM ID table under "event 502" in the TSB (at the link I posted):

Thus, I doubt your vehicle would have had the same FATC update that was done on mine and some others (2016-2017 model years). I point this out only because I do not want to confuse the issue, and it would seem that we are finally starting to narrow down the cause of this problem.
I don’t think that update is the only root to the problem, as mine is first registered in January 2015. Most if not all people in Norway got that issue after a recall for the e-brake where they also updated the BMS.
Interesting - your's is a 2015 with a battery heater? If so, perhaps the points JejuSoul raised about the interaction with the battery heater option have something to do with it.
Was that update - the one you had applied - also part of the TSB for SA427?
If I recall, you (or someone) mentioned posts in a FaceBook group for Norway Soul EV owners having a problem with the heat pump after this update. Do you have a link for that FaceBook group?

I’m not sure how to check if I have a battery heater or the number of the update that messed up the heat pump. But apparently it wasn’t part of the e-brake update, but a service action regarding BMS/FATC they did at the same time.
