So made those changes and no change. Lock/unlock/remote start still not present. Signed out of the app and rebooted phone. Signed back into the app and nothing.
Have not tried to update the firmware of the GWM.
Nothing to update and not sure how to find the files to update to 2019 level firmware.
I am almost 100% sure you will not get this to work on a 2015 Mustang. There have been many that have tried this and no one has reported that they got it to work.
I understand and appreciate you not wanting me to waste my time and effort.
Would you know what others have tried?
I don’t know what they have tried, believe me I wish I was wrong and you could get it working.
What I would like to try next is to update my 2015 GWM to 2018 or 19.
Also would like to find some information on the GWM asbuilt. The database has nothing in it for the GWM.
You can update up to the 2018 firmware with your hardware. But I doubt that is what the issue is with the remote start thru the FP app.
2018:

F10A>JL3T-14F535-AB
F110>DSCM5T-14F642-AD
F111>EB3T-14F536-AA
F113>GL3T-14F642-AA
F188>JL3T-14F530-AB
This is from a 2018 F-150, but likey yours is very similar. There are really no options to program in the GWM from 2013 thru 2020.

Do you have a manual transmission in your 2015 Mustang? If so, Ford will not let you remote start your car thru the FP app.
It is an automatic so that should not be an issue.
The TCU firmware is up to date with the latest Forscan has for it.
The APIM has more than the minimum required but not the latest. So I can try updating that if updating the GWM does not work. I have activated the hotspot capabilities of the TCU and am able to connect and use it.
I will try to update the GWM this weekend and see if that will make a difference. Would any other modules need to be updated to work? TCM or Door perhaps since I am looking for remote start and lock/unlock?
Just the GWM.
Send me the asbuilts for the TCU and APIM, I’ll take a look.
Thanks
Will get them to you when I get the car back this weekend.
@F150Chief here are the asbuilt files for the TCU and APIM.
TCU_20250509_221159.abt (505 Bytes)
APIM_20250509_221238.abt (495 Bytes)
Replaced the GWM with a J series from a 2018 mustang. Deleted the Mustang in the app, uninstalled the app, rebooted the phone, reinstalled the app, added back the Mustang but still no remote lock/unlock/remote start through the app.
Could the lack of lock/unlock/remote start on the app be related to the BCM or PCM? Maybe flashing new strategy/calibration would enable the features on the app.
I doubt that, but you can try. But, I have used FORScan since it’s inception, and IDS before that, and flashing those 2 modules will leave you without a vehicle if the flash goes bad. You would have to use FDRS to recover. Just be careful.
I may try that if you do not see anything in the asbuilts of the TCU and APIM that needs changing.
The TCU and APIM asbuilts are fine. However, I do not recommend firmware updates to the BCM or PCM to try to fix this as I don’t believe that is the cause. From reading other forums I think this is a FordPass thing.
I will try a few more things before calling it quits but I think you may be right. This is likely a Ford server issue. If I am able to get it to work will post an update.
