Ford LIES!

[FastCote]

Chiming in - I was doing some background work to understand what's going on. Looks like the dealer is actively working on it, and engineering are on standby to support as needed.

Thank you. Should I take truck from this dealer and move to another? I stopped using this dealer because they're not very confident in electric vehicles. The only reason I brought it here was that it was literally a hundred yards from where the truck died as opposed to the place I'd prefer.

Thanks for looking that up!

Admitting my ignorance, what part failure would you say the codes point towards?

A weak 12v battery will shed loads (truck components and communications too) and lead to multiple errors, based on what I have seen reported here and on other social media.

Getting rid of the truck may be premature if it just needs a new 12v battery...and a battery maintainer with an AGM mode connected to your 12v battery whenever you are not using it so this doesn't happen again any time soon.

So many Acronyms (FLAs and TLAs - Three Letter Acronyms) like BECM, DTCs, MIL!

Why is there an Illuminated Mother-In-Law in my truck?

Aaaaah!

Love it!

notice how we think every car maker is bad? Except maybe Porsche, there we are jus jealous!

I would love @Ford Motor Company to acknowledge the post from @Adventureboy Keeping the charger active after shutdown. This doesn’t seem like a tough thing to change and could keep a lot of people from being stranded.

The voices of experience in many cases.
Over the years I have picked up a lot of information from car trouble.

So maybe it's like they say, you learn more for your failures than your successes...unless you're a car company, then you just keep repeating the same ones over and over and...

I have your VIN. These are the codes that caused the errors. They are reported as stored codes today, but for sure they are in your DTC history.

Unrelated to what happened yesterday, you have a misconfiguration in your HCM. Not sure if you made some FORScan change that is causing this, but again, this is not related to what occurred yesterday.

Thank you Javier . . . for still being here and helping!

Thank You Brian, for following these post's. (I appreciate it)

But what a pain to have to hook up your truck frequently, JUST to keep the 12v alive and well.
Put a sticky on the dash: "Remember to plug in maintainer"

On this note . . what is the consensus for a good OBDII reader/scanner.
A couple of years back I bought one, was supposed to be good one (So I thought), paid like $125 for it, I could not even read the vin# from my vehicle, I had to type it in every time...It was NOT user friendly

Depends on what you want to do. I'm using a cheap $15 one I bought 15 years ago. It's slow, but I managed to fix my 360 camera view using FORScan with it. Sounds like the app you used was the culprit, not the reader. I've used TorquePro and CarScanner with mine, both connect without issues and read PIDS. CarScanner had more codes auto-populated, I had to create a profile in Torque (which reminds me that I need to update that profile).

I use several of these, battery monitor Bluetooth only. I think they have some with wifi but the cost climbs.

So, I have a question . . Does this Monitor connect right to the battery+/-, or Down stream BMS and +?

That's why I put the SAE cord in so I just open the charge port door to connect it - well, I also have to remember to plug in the NOCO in my garage afterwards as well - yes, I have overlooked that once or twice, lol.

There is always something.

Still a lot less hassle than an ICE vehicle with oil changes, filters, gas station lines, etc.!

With all this talk about battery tending, I am still lost as to how this happened to me. I drive it every day, 30 minutes each way. I also charge it every day. Ford "says" the 12v battery is "fine". They have had it nearly a week and I have no choice but to just pick it up and wait for it to strand me again!

I forgot if I asked or not, but you charge it downstream of the BMS sensor correct?

A 2022 Lightning 12v battery, if it wasn't on a smart AGM battery maintainer as much as possible, is likely on it's last legs.

Not sure how they techs checked the battery, but if they did it correctly, and the battery is really OK, then there is some other electrical issue going on.

Among the things owners have reported are: the PTC (heating element), towing connector wiring, wiring back behind the glove box that was bad/intermittent, a bad component of the BMS (sensor or other part), other connectors under the truck that have become corroded from road salt etc., an allegedly bad HV wiring harness, loose terminals on the 12v battery, and probably others I can't recall off the top of my head.

Electrical problems can be hard to pin down sometimes.

However, 99% of the time (it seems) it is a weak 12v battery.

1/2 hour driving every day should be adequate, except maybe if using HVAC and other 12v system drains from aftermarket stuff or things plugged into the various outlets.

When I had trouble with my 6 month old truck getting an OTA back around the summer of 2024, Ford told me to drive for an hour to charge up the battery. However, that wasn't good enough.

What worked was an overnight charge session on the EVSE to 90% HVB state of charge. That got the 12v battery up over the threshold of 85-90% needed for the update.

Ever since then I have had it on a maintainer every night and when not being used, and so far so good.

The Lightning on its own does not seem to fully charge the 12v battery to 100%, and over time, that can cause sulfates to build up and become permanent on the plates weakening the battery, so it fails under load. That is just a characteristic of lead-acid batteries.

If the techs just measured the terminal voltage without putting it under a load test, shame on them - that doesn't really 'check' the battery adequately.

I hope you can get this solved and not have to give up on the Lightning.
Keep us posted on the result.
