Heated seats not turning on with remote start

I'm also one of the ones affected by this. Glad to see Ford did something about it!
Did mine with FDRS. It works. Proceed with confidence.
So when you remote start now does the button light up or can you just tell due to temp?

After the Sync4 update my seats cool on remote start but I have no way of testing the heated seats since it's hotter than a whale's vagina here right now. I did notice some APIM settings in Forscan pertaining to remote start, but after a bunch of experimentation they had no effect on how the seats behaved.
My guess is the software bug was already fixed when they updated my truck using FDRS last week.

Yeah the dealership tired to update mine and it does not work going to take it to a different dealership when I get a day off
ARod at PTT YouTube channel just release a video on remote start and no heated/ventilated seats fix (SSM 51741).
Just got back from the dealer and can confirm that fix works! Reprograms the DSM and SCME modules.
Just got the SSM 51741 update yesterday. 22º this morning and while lights on the button were not illuminated, the seats appeared to not be ice cold, but certainly not hot by any measure. I changed the climate settings from "auto" to "last", turned on the AC seats, and did a full power cycle and remote start and the AC seats were definitely on. So seems to be working... just not very hot. I'll take mildly warm over freezing though.

Bummer. I'm scheduled to get the SSM update in a couple weeks and was looking forward to it now that it's getting colder out.
My dealer sucks nothing works in my truck seats still don’t work so when I come out of work at 1:00 am they’re frozen and still no full screen apple car play admittedly I don’t use car play anyway at this point I just can’t waste anymore time on incompetence truck will more than likely get traded for a 25MY anyway
I had my update done and my seats still do not turn on with remote start
The red LED lights will not turn on after a remote start until you PTS/Key-on. I had the SSM 51741 done a couple weeks ago. I hooked up FORScan to verify the fix. At that time, the seat AAT was approx. 55ºF, I remote started at about 20 sec on the graph, let it run and the seat temp rose to approx. 118ºF when I pressed the PTS at about 199 sec mark. So the seat temp went from 55ºF to 118ºF in 179 sec or 2.9 min (which equates to approx. 21ºF per min). I have not actually tested the max temp reached after PTS or what the temp is for 1-3 red LEDs. MY IC menu settings for remote start are Climate Control = Auto; Seats & Wheel = Auto. Only way to accurately test is with FORScan and the seat temp PIDs, or less accurate readings by using a IFR thermometer or your hand to feel heat , but obviously would be subjective.
I know they won’t light up until the key is turned. I know they aren’t working because my balls freeze to the seats still after remote starting. Haha
How do you monitor this in Forscan? I have Forscan but have not used it for this purpose before. I would like to verify the fix they did in August before it goes back in January.
@njburn Click the icon with the yellow squiggle line (3rd from top left side), hit the gear/settings, then select all modules, then you need to select the following PIDs. Oscilloscope tab will present the graph.
Very helpful, thanks. It was 22º and I let it run maybe two minutes before hopping in which would account for my feeling that it was not quite as cold if say it was at 40º - 60ºish instead of ambient. I'll give it a shot tomorrow and let it run five minutes. Appreciate the info!
Trying to get a little knowledge from those here that I'm sure know more than I. 2021 Platinum Tremor, and I do not think my heated seats are functioning properly on remote start (RS). With a 10-minute remote start at below freezing temps, the lumbar portion of the seat warms slightly (maybe to 40-50 degrees) but the actual seat does not warm at all (Heated steering wheel warms nicely to about 80 degrees). Activating the heated seats on regular push button start (PTS) and the full seat warms to 90+ degrees within 5-8 minutes. Is there a purposeful temp difference PTS and RS? Is this something I can change in Forscan? I have had the dealer tech look at it twice and they said they cannot find anything wrong with the system. They tell me that the heated seats activated on RS will shut off after PTS and you have to reactivate them (They said this is by design). However, when I PTS, that's when the heated seats actually come on without hitting the heated seats button and the warming commences (especially on the seat portion of the seat). Am I delusional? Am I expecting more than what they are designed to do? Any help setting me straight or in the right direction would be greatly appreciated.
