Heated seats not turning on with remote start

[catastrofe]

that's because diesels take a long time to warm up, check the coolant temp after your 10 min remote start. if its not warm your not gonna get any good heat. I feel like after 1 remote start its decent, 2 remote starts and its starting to get warm and by 3 miles down the road its coming out pretty good. just really depends on how cold it is out. if its freezing its gonna take a long time for it to warm up

With the heat on auto setting, it doesn’t seem to blow any warm air until the engine coolant temperature is about 80 deg F. So depending on outside temperature and engine temperature when you start it (use block heater or not), it could take quite a bit of time. Block heater works awesome and the engine temp is almost 80 right away, even at -3F. Also, high idle kit helps a lot as well when set to 1500 rpm.

Thanks, I figured it's related to a cold engine.

My 22 lariat ultimate does not heat the seat. Just the wheel. Hopefully a fix is in the pipeline.

this feature 100% worked before the last update.. it frustrated me for the past 12m with it coming on every time i remote started and it was warm 10c (50f)

unless it works when cool.. but not cold ?

Upon further messing around, I tend to agree with RedZilla that the seats DO heat but only to a low setting. I do NOT want to raise my low setting, because often the high and medium are too much.

Perhaps Forscan will let you assign the higher temp to Low, and lower temp to Medium? you could then switch as needed...

Following.... it's been suggested that maybe it has something to do with the M/C seat delete option.

Definitely doesn’t have anything to do with that

Anecdotally, it appears that many had properly functioning seat heating on remote start up until the last Sync update was installed. My software indicates it's up to date by the Ford Pass app and my seats definitely don't feel warm when I remote start the truck with temps in the negatives these past few days. Really a shame to have paid for a feature and it stop working due to a software glitch right when you really need it.

That sucks. Mine's so new, I probably got the updated/cr@p version out of the gate.

Brand new truck, remote start heated seats don't work, and mine has the deep sleep problem too (I know there's a fix, but dealers... ughhhh)

I’m intrigued by the update thing. My truck has never seen an update as I’ve had the fuse for the modem pulled pretty much since day 1. Also never connected it to wifi, as that requires the modem to be active.

It’s possible I had the update from the factory, but I sure had an early 22MY truck.

Curious if anyone who has the heated seat / remote start issue has also been playing with FDRS? Wondering if a full suite of updating all the modules that need it has restored the heated seat/RS ability?

Hoping to have my Mongoose today, and fix Fordpass/deepsleep.

MY22 F350 6.7 PSD Limited, I also have this no seat heat on RS activation issue until I hop in the cab an push the PTS. Kind of defeats the whole purpose of having IC menu settings for RS for the Climate Control (AUTO or Last Used) and Heated Seat & Wheel (AUTO or OFF).

I would be interested in knowing what your firmware and calibrations are for each module prior to and after you do the module updates, so I can compare to my modules firmware and calibration.

There is a thread over on FTE that I started on this very issue that you might want to take a look at. So far, with the help of ZooDad, we have tried certain FORScan changes in the HVAC, DSM and APIM modules, but unfortunately none of those changes have resolved the issue.

HVAC- NC3T-18D619-AC
DSM- JU5T-14C030-EP
The APIM just says ML3T, but details has all sorts of other stuff. My Sync is 22026_PRODUCT, rev 354

I am unable to update the GWM to get the new APIM update.

LMK if this is helpful, or I can DM you the module detail if needed.

Thanks, I'll go pull my module data and compare. Appreciate the help.

ok guys heres how you run a module reset in forscan click that and scroll down to HVAC and do the reset.View attachment 104420

Look in your as built and check this setting it might have something to do with the heated seats my truck has a 1 there.

I checked my programming and I also have a "1" but my seats don't seem to be on until I "push-to-start". They may be on low, but it's hard to tell if that's just from the heat blowing from the vents....

I would wager they are not on. I took a laser thermometer to mine just to be sure (easy). When they're on, you can tell within a minute. If you can't tell after 5 minutes, they're not on.

Sit In the truck and remote start it, give it 10 mins while sitting In it and see if they are heating. You guys are focusing way to hard on the lights. When remote started there’s not going to be any indication on the HVAC module till you push the button. My seats don’t get crazy warm but they are heating while remote starting.

Sitting in the truck and trying to tell is difficult because you’ll warm them up yourself. If they’re on high it will be super obvious they’re on, but if they’re only on low then I’m not so sure.

Agreed on the lights, though. The lack of lights means nothing as proven by the fact there’s no lights indicating the HVAC system is powered on, but clearly the fan is running and, if the engine warms up enough, the cab of the truck warms up.

You can also use the FORScan PIDs and monitor seat temp. As you can see on the graph below, constant seat temp, and then when I press the PTS, the seat starts heating.

Have you looked at your forscan settings to see what the low temp is ? 52 degrees sounds like low setting. When it gets cold enough I’ll check mine.

That particular test was after I did some prior tests so the seat was already a bit warm. I have since added the ambient air temp PID b/c per the Ford Work Shop manual, the theory of operation is < 32*F will trigger seat heat, and > 80*F the cooling seats should come on (ambient air temp sensor is under the passenger mirror) and is show on the 12" infotainment screen. I've had several FTE members reported their seat heat comes on when the ambient air temp is 40-50*F. I've run tests at -12*F ambient air temp and no seat heat until I PTS. ZooDad and I have looked at your GVM module firmware and config and you are a version ahead of me. HVAC and DSM and SCME modules config and firmware are the same, if I recall accurately. I have a dealer appt for my first oil change on 2/6, so I will ask them if they can update the GVM and see if that fixes it.

But it would be great if you test with FORScan PIDs and report back what your findings are.
