Pro Power reserve limit fails

[dmd3home]

Indeed, the update was for a lot of stuff that I don't have....Sirius and Blue Cruise etc.....why did we even get this? I have none of it! Is this what caused this change in my "reserve" setting function in PPO? Did it cause, yet to discover problems, as well? Is this just a "one off" on my truck?....or is it systematic? Let me know how yours works.

I know, what a pain the OTA process is...I need PT-25-13-12 so I can get the FORscan tweak for PPOB when truck is off to work, but no way to instigate it - just have to wait for Ford!

My misreading of the FORscan post.

OK. I won't get to test it until tomorrow.

I have it charged to 90% so it'll take a while to get to a 10 mile or even a 46% reserve level.
It is supposed to drop into the low 30's here tonight so I have it plugged in for battery warming.

I'll hook it up to my house transfer switch tomorrow morning and see how it goes with the reserve.

Later.

Indeed, Ford just hasn't figured out software and OTA updates. I'm used to Tesla....everything just works!!!! Though they've had much more time to perfect it. It's said that Tesla is really a software company that also builds cars....whereas Ford is a car company that does some software. Keep me posted...thanks.

Oh, and yes, I too would like to get PPO to work with the truck off and am waiting for that update. I seem to have trouble getting updates....even with the truck at a fairly high SOC and my 12v on a battery maintainer. But I didn't realize it still too a FORscan modification. I've been staying away from altering my own software....didn't want to void warranty. But now, maybe.

I was wrong about needing the 25-13.12 - if you have a 2023 truck, it's the 25-8.5 required.

I had misread the post as saying I needed both.

I also thought the toggle was in the APP but now I realize it must be on the truck screen - my bad!
-----
Enable Pro Power Onboard with truck off (2022-2023 only. Standard on 2024+).

In the settings that follow, “x” means leave the value as is and

“-“ is the checksum value that FORScan will re-calculate for you when you write the data.



An " * " means the new value depends on the old value so read the notes.

While all the settings can be done using As-Built Mode, some can be done with “Easy” mode. Both are shown where applicable.

Creates a Sync toggle in the Pro Power settings screen.

See this post for operational details.

This mod requires a PCM update that came out in early 2025 via FDRS. However, the Charge Port OTAs that came in early 2026 will also work (PT-25.13.12 and PT-25.8.5).

7D0-10-03 xxxx xx2x xx--
7D0-10-04 xxx* xxxx xx--

If 0, change to 8.
If 4, change to C.
If 6, change to E.

If you enabled the Advanced Charging Screen, you likely have a 6.

The issue of "getting" is under the control of the FoMoCo, their scheduler is schizophrenic, the LVB SOC has nothing to do with deployment.

Yes, very inscrutable.
The issue of 'distribution' of updates from/by Ford does seem rather "random."

Receiving them is subject to at least a couple of things having to do with the truck:
1) LVB SOC - some require at least 85% it seems;
2) being in a location with good reception - in my garage there is no cell service for my Nissan Leaf for example, but the truck in the driveway usually does ok.

So I think what @dmd3home meant was maybe it is hard to know if the issue is Ford not sending an OTA update due to the crazy inscrutable scheduling, or the truck not being able to receive it due to a funky battery which @dmd3home was coping with.

It'd be really nice for us owners to be able to go on line to a Ford site and aschedule an OTA for our trucks.

Even better would be if we were able to download an OTA update to a thumb drive or laptop, and load it onto the truck with either the USB port or the OBD port.

And Ford could to maintain a database of the updates that we could access, or at least a complete list of the ones our trucks should have.

Things are just too random the way they are now...alas.

Tweaking some of the options that are hidden should not void a warranty per se, according to the rationale the FORscan folks use.

The PPOB when truck is off is one of those - and if it is enabled in the 2024+ trucks, no reason to worry about it in the 2022 and 2023 trucks, eh?

Yes using FORscan could be risky if one is not careful - that's why the first step is to save the AS BUILT settings to a laptop and back it up somewhere as well, so that if you make a booboo changing things, you can reverse it by reloading the original AS BUILT settings.

That took a while since it has to be done one by one.
The change to enable PPOB when truck is off took less than a minute.

I am running the PPOB test now with the truck off, to see if the problem you had with the reserve is due to the update you mentioned or if it is your 12V battery being weak.

I set the reserve at 119 miles because it would take forever to go down from over 200 miles to anything lower. Our house emergency circuits don't use more than 1kW unless I run the microwave or have the coffee pot on, then we barely get to 1.5kW and only briefly.

So far, nothing unusual at 197 miles and still hovering around 90% SOC.

If it cuts off before the 119 mile threshold, then we'll know the update screwed the pooch.

But I'd bet it was your 12v battery issue, a weak one manifests in so many strange ways in our trucks...

I lost that bet - it happened to me too!

 

[chl]

So, I was running PPOB, set the threshold reserve limit to 119 miles - I started at 90% and 209 miles range.

Ran fine for several hours.

I started out running PPOB with truck OFF, but turned the truck ON and got in it because the APP was not showing any change in the HVB SOC or the range at some point.

Also, when I looked outside, my FRUNK had opened by itself!!! That was a behavior someone else reported last week I believe. My doors were still locked however. I thought maybe that is a sign the 12v battery is running low, so I got in and turned ON the truck after closing the Frunk.

When I turned the truck ON, the APP updated with the accurate numbers being displayed on the dash screen.

The PPOB ran for some time after that, maybe 30 minutes but...when it got to 191 miles range and 87% SOC, the PPOB shut OFF.

With the truck ON, the 12v battery would be being charged, and up until I started this test, the 12v had been on a maintainer, so even if during the test, the 12v battery was drained somewhat, turning the truck ON should have started restoring charge to it.

So I cannot connect the 12v battery SOC to the behavior of shutting down the PPOB way before the reserve threshold had been met.

In the past when I used the PPOB for several hours, it did not shut OFF before the reserve had been reached, I shut it off manually after several hours.

So, I have to agree that this latest update, the PT-25.8.5 messed things up.

 

[dmd3home]

Indeed! And, as I said, I've used the PPO for a few years now (actually why I bought this truck over Rivian and others) without any issues (other than having to leave the truck "on" for hours). And, I always had the "reserve" set at 10 miles. Oh, and I always keep a battery maintainer on the 12V. And, the auto shutdown timer off. So, to suddenly have this issue is likely related to that update. Coincidentally, that update (Feature Enhancements.... PT-25.8.5 ) while updating, caused the motor/pump on the right side of my rear axle/differential to run loudly, obnoxiously loudly to run for 40 mins all through that update. I posted about it here (https://www.f150lightningforum.com/...-update-causes-problems-while-updating.35780/). Ironically, as a stripped down Pro model, I don't believe I should have received this update in the first place. And here I've been complaining about not getting any updates. Careful what you wish for!

Well, what a pain in the butt this is.

That PT-25.13.12 does have something to do with more than just the things described in the text, i.e., SiriusXM, because it is a necessary prerequisite for the PPOB when truck is OFF tweak.

So defintiely affects the PPOB somehow - apparently not in a good way!

Drat!

Not sure how my frunk opening by itself is connected to this...what a cluster!

 

[dmd3home]

Indeed! At least, as I said previously, I am fortunate that I have a EA charging station within 3 miles and can set my "reserve" not to 10 miles but to the nearest charging station.
Now I'm wondering if, as I said above, this might have had something to do with that motor/pump running during the download/install. Because it ran continuously for 40 minutes (!), and, I believe running off the 12v battery, it may have drained the 12v low enough (in spite of it being on the maintainer...very low amperage) to interfere with an accurate install.

Ghosts in the machine...

I guess I might have to use the nearest charging station as the reserve - do I have to charge there first? There are several within 2 miles of my house but never use them.

 

[dmd3home]

Yes, I believe you have to charge there first....kind of strange.
Through all this I did change my home charger as someone suggested I might have never set it up. I had, but did notice it had the wrong address. I decided to try to correct it, but to do that I had to first delete it. But when I tried to manually add it, with the correct address this time, I couldn't until I charged first. So I charged at home for a few minutes and then stopped. Now I could add it as my home charger.....but, of course, it still came up with the wrong address....guess the Ford GPS isn't too good.

 

[TaxmanHog]

it still came up with the wrong address....guess the Ford GPS isn't too good.

Don't let the "wrong" address throw you for a loop, accept the GPS positioning for what it is, this has always been my experience as well, if it suggested you were at your neighbors property ignore it and move forward with the scheme build.
