Yes, that is the correct fuse. Strange to call it that. Its called the Telematics Control Unit for other years. See here:

Lately I have been hunting a 880ma parasitic draw in my 2017 FFE 12 low voltage circuit. It has been trying to kill the battery every week that I do not drive it. Though I did not have a problem before, I got a hunch its that damn TCU. Will also need to pull F1 and see if the draw goes away.

Thank you!
We've pulled the fuse from the "Cellphone passport module", fuse F1, rating 5A, located in the Luggage Compartment Fuse Box.

So far, so good--I took our FFE out this morning, and all seemed fine. I was wondering if I'd lose any other capability if I pulled that fuse, but I didn't notice anything (for example, I am still able to use CarPlay, etc.)

I'll just bide my time til the elusive 4G modems get in stock... :roll:

Again, thanks for all the help! This FFE is back on the road :D

None of them seem to be listed as TCU or TCM, but there is a "Cellphone passport module", fuse F1, rating 5A, located in the Luggage Compartment Fuse Box, which sounds suspiciously like it might be the one? Could anyone verify whether it sounds like I've got the correct fuse to pull?
Yes, it's Fuse 1 (blue for 5V) in the back left of the trunk. The one lowest in the fuse box, iirc.

Surprised you were still on the factory battery. They only tend to last 3.5 years at best. I put in a LiFePO4 12V battery to replace my 12V battery. It has a BMS that will disconnect the battery at 10V so if my TCU tries to kill the 12V battery again it won't. I also installed a low voltage disconnect meant for use on boats that cuts power to the TCU if battery voltage drops below 12.1 v. I actually had this first to protect the factory battery but pulling the lead battery down this much often isn't good for it. I've had the lithium battery for a year with no issues. In theory this 12V battery should outlive my FFE.

Regarding loss of features, you will lose "Go Times" and "Value Charge Times" by pulling the F1 fuse since for some reason these features depend on the TCU.

I like the go times but I can live without them if it's going to try and kill my 12V battery. For me the money isn't worth it for the TCU upgrade. Especially with no guarantee in how long it will be before 4G is turned off and the TCU becomes another expensive paperweight. Real glad I didn't spend $700 a couple years ago to replace the TCU when it started killing my 12V battery.

It has been more than a month since the modem was updated in my '16 FFE and it still does not work. I have had an open case with Ford Pass for several weeks now with no resolution. So, even though I did not pay for the upgrade, I essentially ended the my ford mobile service two months earlier than it would have happened with the termination of the 3G service. I will update if and when I get a resolution.
Within the past week, the Ford Pass app now shows the Charge level percentage and estimated distance to empty. The app also alerts me when my FFE is fully charged. However, the remote functions (lock, unlock, and start) still are not working. On a positive note, a rep from Ford pass contacted me this week to inquire if I am still having issues and he assured me they are continuing to work on a resolution.

Registered for this forum just to post this:
I own a 2018 FFE. Got my modem ordered a day before the MFM shutdown (Around $380 or so) and got the upgrade done on March 1st. Activation prompt for FordPass showed up around March 4th. After activating, I confirmed I could Lock / Unlock / Start the car remotely. I am disappointed we don't have the notification settings we had with MFM, but oh well. The UI does look much nicer, and the car takes much less time to respond to remote commands.
One thing I do find strange is that I'm still able to access/edit GO Times and Charge Scheduling both through the FordPass app and through the Sync 3 Infotainment, which Ford explicitly said wouldn't be available until an OTA update this summer. I have not yet confirmed if they still work, though, but I've heard other people who got the update have a blank screen on their Charge Scheduling / Go Times in the infotainment, whereas I just have the normal screen from before the upgrade.

I had also heard of multiple people having issues with the upgrade, but other than the activation prompt showing up later than Ford said it would, I've had no problems.

Can those with the update post a screenshot? I'm missing charge level and range. Only have lock/unlock and remote start. Fordpass support said the modem isn't provisioned properly. I don't trust the dealership and would like to have something to show them. They kept the car for days for this and the service tech had terrible communication.

Alright. I finally got my LTE parts kit yesterday and hooked it up today.

Ford Pass lets me add the car by VIN but doesn't really show me anything indicating it's talking to the vehicle - no statuses whatsoever.

The modem is seen by the Sync head unit and reads out the serial number. I don't see any option for activating or connecting Sync even after a master reset.

Anyone have any ideas?

On mine I had to complete authorization for the modem. If you have Forscan, there's an authorization status indicator that will tell you whether it has been authorized. My 4G upgrade still is not fully functional. I have no charge status or range indicator, and only my wife or me can be authorized at a time. I'm going to take it back for an IDS update, but I can't tell if the issue is vehicle software, or something else with Fordpass. Some people have had success completing the authorization using the website below.

https://connectedcar-sdk.com/

It uses Ford API to push an authorization request through Sync and will show your current authorization status. I also posted on the Cyanlabs forum about my issues:

I gave a call to FordPass support, told them I was sold the kit because my car had Sync3 like the others that are officially supported. They seemed willing to try and troubleshoot but the modem itself was not associated to my car. It seems the "programming" part of the setup is updating the records on the back end - I'm guessing the IDS stuff you mentioned.

I have an appt Wednesday morning to have them do that programming. After that, the system should hopefully recognize that I have a supported modem and start talking to the vehicle. I tried the API push you provided and there's no change. Which isn't surprising if Ford thinks my car still has a dead 3G modem installed.
