ProPower Onboard Unavailable, and windows not working

[Jerry Can]

My truck power outlets, rear passenger windows, rear sliding window, moonroof, and accessory fuse powering my dash cam all no longer work. Any guesses what could be causing the issue?

Would be interesting to see what DTCs are being thrown on your truck.

If you
1 shut the truck down, then
2 open the door to complete the shutdown
3 exit the truck and walk away and remote lock it

4 return to the truck
5 enter, but only turn on accessory mode. (don't press brake)
6 wait about 15 seconds and then hit brake and start the Powerboost (Green Ready indicator)

Now does Generator mode work?

just gave that a try; unfortunately it‘s still not working

Bummer.
I was hoping it was just a low voltage scenario that resulted in a temporary communication failure at boot up.
That "2-step" startup method on a Powerboost leverages the High Voltage battery for supplying ample low voltage current to the truck at boot up.

The only other cheap (free) thing you could try is to disconnect the negative terminal from BOTH batteries for a while. Sort of a full "reset" of the ensemble of modules in the truck.
Be aware that it might also clear your adaptive tables and memory settings in Sync and the like.

Still, I'd love to see any/all codes harvested first. And then cleared.
Do the battery task and then harvest codes afterwards to compare. (if the issues persisted)

@Jerry Can. Since you have a 2021, your generator issues might be related to the software in your BCM and PCM. See TSB 23-2407:

TECHNICAL SERVICE BULLETIN
DCACA Inverter (Minor Feature Code HUKAK) - Pro Power Onboard Unvailable Message In Center Display Screen - Diagnostic Trouble Code (DTC) B15DA:09 Stored In The Body Control Module (BCM)
23-2407

08 December 2023

Model:

Ford
2021-2022 F-150

Issue: Some 2021-2022 F-150 vehicles equipped with a direct current/alternating current converter module A (DCACA) inverter (minor feature code HUKAK) may exhibit a Pro Power Onboard Unavailable message in the vehicle center display screen with DTC B15DA:09 in the BCM. This may be due to the software level of the BCM and powertrain control module (PCM). To confirm a vehicle is built with a certain minor feature code, review the build information by double-clicking the vehicle identification number (VIN) in the upper left corner in the Professional Technician System (PTS). To correct this condition, perform the Service Procedure below to reprogram the BCM and PCM to the latest software level via the Ford Diagnosis and Repair System (FDRS).

I think I’ll be taking it to the dealer to have it checked out. But I’m out of town at the moment, so it’ll have to wait a week or two. I‘ll provide an update after I’ve had it looked at.

Thanks, I’ll schedule an appointment with my dealer and mention this bulletin

As a follow-up, there were no codes. It was a blown fuse that I had my dash cam backup battery connected to; specifically the passenger compartment fuse 2 (delayed accessory feed). I really wish I had checked the fuse before sending the truck to the dealer. $200 to replace a $2 fuse ?‍.

Whats really bizarre though, is that the blown accessory fuse somehow caused my windows and ProPower Onboard to stop working. How are these in anyway connected in circuit to a 10A accessory fuse?
