Need Forscan help on 2019 F150

[Gdocgray]

SOS!
I tried to disable the PowerPoint timeout on my 2019 F150 because I’m a First Responder and need the plug to remain hot with out the truck running.
I’ve tried everything that I’ve found on the web, including the Forescan worksheet and it still turns off when I cut the engine off.
please help with this issue!

Confirm you have:

726-39-01

xxxx

x0xx

xx--

Then reboot BCM in service procedures. If that still doesn't work, the spreadsheet has a hardware mod to do the disable.

Alternatively, set

726-39-01

FFFF

xxxx

xxxx

Which gives 18 hours, 8 minutes, should be long enough.

Thanks for responding!
Sorry, still new to this. The spreadsheet I had showed a 726-57-01,
That could be the problem. I’ll try that one and report back.
I’ve tried The jumper and both times caused the truck to completely shut down and a new alternator and battery

 

[SilverPigeon]

Yeah, 726-57-01 is mainly lighting configuration

 

[Gdocgray]

Ok. So update.
I tried it this morning, the FFFF said incorrect configuration and wouldn’t write. The x0xx changed from x1xx only stayed on until I locked the doors.

Can you screenshot the 726-39-01 part of the configuration display? It's possible that they've set a limit on time and that setting it to maximum doesn't work anymore. It's also possible that no matter what time we set, it only works when the teuck is unlocked.

I’ll get a screenshot this afternoon. I found a group on Facebook that suggested this:

Still turning off when I take key out

Yes, that's the same as we were doing earlier. You can try to enable the timeout with a number of seconds greater than the default but less than maximum, like this:
726-39-01 1FFF x1xx xx--. Leave the "x" at whatever they currently are. That value makes for just over 2 ¼ hours. If that works, and you want longer, increase the "1FFF" until either you are happy with the length of time, or you get a configuration error.

If that doesn't work, I'm out of ideas

 

[Gdocgray]

I’ll let ya know! Thanks so very much!

Here is something:

Have you been trying this with ignition on? Does your trim level of truck allow the ignition to be on and engine off and doors locked? If not, try engine off, ignition on, doors locked.

 

[Gdocgray]

Switch to on, but not running. Door open because it’s Texas and hot lol.
thenonly thing I haven’t tried was doing it with the doors locked. I tried the last config you sent and it was a no go
