Forescan blamed for Battery Monitoring System not working correctly.

Long story to be updated...

Went to the dealer about a month ago because I was receiving the 'system shutting down..." message and ASS not working and was hoping they would just replace the battery under warranty. Dealer ran their tests, replaced the battery and ran the tests again and decided it wasn't charging correctly and needed to order a battery monitor sensor. Part came in and took it in today. I get a call that they replaced the module, but it still isn't charging correctly and noticed the Sync screen was changed and asked if I had made changes with forescan. Busted. I said I did and the service rep told me they suspect the changes were affecting the charging and would need the second key to reprogram everything. She told me they couldn't even get the truck to start now. Knowing that my trail management change would likely be noticed, I took the original switch in also and fessed up to that change. I also told them there was a brake controller installed.
The forescan changes I made and forgive me for not knowing the correct terms... cornering lights, Sync splash screen, speed limit detection, frost warning, off-raod gauges, and the changes for the trail management switch. All were done off the menu items, I didn't change any codes. Never changed the battery charging %.

Now I'm waiting to hear back tomorrow on what they found and hopefully they have it running again.

I haven't ran across any other posts that I remember where the dealer is blaming Forescan changes for the battery issues.
Anyone else hear of any?

Update:
Got the Ranger back with almost all the changes in place. I still don't totally understand the problem but from what I can gather, the BMS was replaced and when they reprogramed something, it didn't match up with the changes I made and caused it not to start. They reprogramed the keys I guess, and got it running. All the changes I had were in place except cornering lights. They didn't even change out the TM switch. I was warned that the changes that were made weren't covered under warranty, but they absorbed the additional time.

Very happy with the outcome. I've purchased from this dealership previously and will be returning back there for service or when I'm due for a new vehicle in the next couple years.

I've had trouble with my truck always saying "Veh. Charging" as well. I recently replaced my battery and reset the BMS. It was fine for a couple of days, but then immediately went back to doing the same thing. I've only made a few minor alterations with Forscan. I wonder if I should try loading my AsBuilt file and resetting everything.

I had mine towed in for dead battery. I had made several Forscan changes. Including disabling ASS, splash screen, changing DRL settings,etc. Dealer made no comments about changes. Tested battery found bad and replaced. No charge.

I think it was the replacement of the BMS that was the issue with my forescan changes.
As the video here says, there is a microprocessor in it and probably needs updated in one of the main systems.

Probably wouldn't hurt. Especially if you take it to the dealer to have the bms checked out.
Not sure if you saw the new post with the video of the bms system.

I finally got around to playing with FORScan, had to get the free extended licence first. I am using the ODBLink EX cable and it worked flawlessly.

1. Set SOC to 85%, was 75% as built ( I see people report theirs at 70%, maybe Ford adjusted for 2021)
2. Turned off the fake engine sound
3. Turned on Bambi mode
4. Changed to double press for the panic button. On my Oregon to Ohio trip this summer, I slept in the car at rest stops and managed to set off the panic alarm at 3 am in a packed rest stop. It took me several seconds to realize what was happening and get it to stop, very embarrassing!
5. Turned off the start/stop, but then turned it back on the next day after I realized it might disable the whole battery management system which I want to keep. Back to pressing the button.

After that, I decided to update my Sync to 3.4.22200 and maps to 2.21. Then I updated the firmware in my Viofo A1119 V3 dash cam lol, I was on a roll!

Has anyone figured out how or if we can change how many blinks for the turning signal if just touched, default is 3 would like to change it to 5 like I did on my F150

I do remember reading somewhere that you can change as built code. Not sure if it was ever confirmed maybe search Forscan forums I think I read it there.

UPDATE
I figured it out and this ONLY applies to Factory LED or Aftermarkets that have a dedicated DRL and that is all you will be using.

DRL Configuration to (Dedicated DRL)

Set this option to (16) Dedicated DRL - this will automatically set 2-Lines of Hex Code for you.
NOTE: the (16) is a Binary code that is converted to HEX (Inside of the As-Built) Files

Here are the 2-Lines of Codes it sets

BCM
726-26-02 - 0000-0001-0056 (Matches my Lariat compare search-As-Built)
726-50-01 - 108E (Matches my Lariat compare search - As-Built)

Now set Allowed DRL Options:

NOTE: The Paragraph at the top
If you have only (1) option for DRL, such as Factory LED Headlights, this will show due to the fact that it matches the (16) Binary code you set in DRL Configuration PLUS
This option ONLY modifies (In addition) (Plus) the standard factory DRL.
So, this normal - As I have not added any special (extra) DRL options to the configuration

So, with this selected, here is the last Hex Line of code that is changed (Automatically)

726-45-01 - 0A01-1000-008E

If you do not see this option (highlighted) then go into the As-Built File and manually change it, then when you go back to the (Module) Easy way, this will be shown

I know there have been quite a few posts on this subject and I wanted to pass along my findings
to clear it up
These are the confirmed settings for the Lariat Factory LED Upgrade, now it should also clear it up for those who have installed the (aftermarket) options. With the attached pics, you can see it more clearly and visualize what changes you want to make

Hope this helps

DRL wiring is absent on non lariat rangers from my understanding - the set I bought instructed tapping a fuse at the box to get DRL working (believe harness lacks pin that lariat has). Going to be peeved if it just needed a seeing adjusted.

This has been covered a few times, none of the potential adjustments that exist work in our NA rangers.

I have Lariat, but it was my understanding the wiring harness itself to the headlamp assembly is the same for all Rangers. I had factory halo's installed at delivery, thanks to Ford deleting the LED's
Wiring harness to headlamp was the same, somewhere on this forum show the plug and pins difference. (On the headlamp assy itself) (Not the Harness)

Now internally withing the headlight assembly the wiring is different, moves the DRL from Lo Beam to the LED Strip, this is why ForScan is needed, to configure the BCM to send the power feed changes to the different power (pins) internally of the headlamp assembly
One main difference in the pins (internally) is that you no longer have (amber DRL/Park/Turn) you only have amber (Turn) and the DRL is moved from Lo-Beam and Park to the LED Strip)
All of this is internal (within) the headlamp assy, nothing to do with harness
Now this is true for the Factory Lariat Headlamp swap from Factory Halogens

Not sure what the 2 Aftermarket Options have as far as pinouts, I believe the issue with these was having to do with (DRL/Park/Turn) and using switchbacks

See attached LH Headlamp Connector, this connector shows in the wiring diagrams for all rangers, not specific to Lariats

I guess I could test - just need to make those above changes and try the built in harness. Glad I hacked my fuse box hah.

There's a video in this thread, and the description references Forscan; does anyone know if it really is Forscan what the tech is using?

I think he is using Ford's IDS (Intergrated Diagnostic Software)
I have only used ForScan for my mods, so I don't know if ForScan can view live data or not, if it can you can see same data he is viewing

I have an Autel Scanner that can show the exact data he has on the screen, what he has done is brought up Live Data and selected these PIDs (custom) screen to clear out clutter, plus when in custom screen you get a faster refresh rate (most accurate - live data)

@p3zz - I looked recently in FORScan, and you can see live data, but the data points he's looking at are not available currently for viewing. I went and checked not long after I saw this video.

Anyone know why the Auto Start Stop is in two locations? I disabled it in BCM but also today in IPC since the disabled indicator stopped appearing.

Edit: I guess IPC is the indicator only? https://www.ranger5g.com/forum/threads/forscan-modifications.1844/post-265981
