Yes, it's Fuse 1 (blue for 5V) in the back left of the trunk. The one lowest in the fuse box, iirc.wind_driven wrote: ↑Mon Mar 07, 2022 2:00 pm
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?
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.wind_driven wrote: ↑Tue Mar 08, 2022 1:03 pmThank 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...
Again, thanks for all the help! This FFE is back on the road
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.a4bry4 wrote: ↑Thu Feb 03, 2022 9:00 pmIt 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.
