The fan "trick" is to change it from discharging or sustain, to actually charging.

The fan "trick" is to boost from 12.7 to 13.9 volts or more.

So yours is at 13.9 by coincidence for some other reason.
25MY Lariet hybrid. Mavester Mechanic indicated that using FORScan to include tail lights with DRL will Not trigger further charging from 92% to 100%. He is correct. I did the Forscan change, tail lights indeed come on with DRL, but does not trigger further charging. My Mav with 14k miles, AGM battery, behaves as he describes. Charges normally to 92% w/o tricks, then begins discharging, indicated by 12v battery voltage & immediate discharge of 12v battery current. Turning on parking or headlights instantly reverses 12v current polarity & charges slowly to 100%, reducing charging current slowly to 1 then 0 Amps at 100% SOC. DRL w/ tail lights acts same as lights off, no Tricks. I'm still leaving this Forscan change so rear visibility is improved if DRL are used. My Truck is behaving well now. FYI, fan speed to "6" is too high for me, so Parking lights is my Goto trick.

To be clear I don't have or use Forscan.
I was hypothesizing and asking others to try making the change and see what happens.

Update:

Been using parking lamps or headlamps almost every drive since April.

My battery has stayed 100% charged since.

(It will drop to 96% overnight and maybe 94% over a long 3 day weekend.)

So it's apparent (again) that the trucks stay awake in the first 1-2 hours after parking and lose 4% battery right away. Then it tapers off and eventually there will be next to nil parasitic drain.

4 years in I'm convinced it's not a parasitic drain issue in most cases. Rather it is the programming that for whatever reason does not want to fully recharge the next day without "The Tricks" TM

I also believe the tricks will not work on bad battery that is beyond recovery. On my former battery, I always got the same voltage reading using the tricks or not. When I charged it, the tricks worked, but the battery then drained over three days of non use. Took to dealer and got my second dealer installed battery. This time an AGM.

Forscan is a stalled project, it can not be funded from out side its host country. Fords are very unseen in this host country. There is conflict that needs to end before payment can got to people waiting no. VB CC VB B B C B N

It may be stalled, I don't know. It is, a great alternative to fix many of the Ford issues.

I agree...... Have you tried clicking your heels before turning the key.

Sure its stalled, they been recalled to active intel, they are experts in remote intel of Ford based vehicles, who has the number one sales of trucks? finished the transfer of Mosad like protection to Ukraine 2 months ago, let Russia see it happen, that mission is over Russia view is over. Its been 7 weeks and counting to get Russia spy out off every thing.

Wow - no flack, and doesn't even sound like a terrible battery yet.
Great dealer.
Compared to @REMUB40 whose dealer told him only SLA could be installed since it came with that.
Or the fact they had no AGM in stock to use.
