ECU module programming guide using FDRS

[ChiefD]

I noticed that my battery shows a 50%. charge and 12.5 VDC when I hook up the battery tender when doing updates. I charged it up to 100% charge Monday when I last did updates and today when I hooked up the tender it was back to 49%. I think I don't have the best battery and it might explain why it was dead after the last time the dealer tried the updates. Anyone know if this might impact the USB kicking off the APIM update?

From what I've read the update logic is the same. 12v battery must be SOC 80% or greater for the update to greenlight.

It's in the troubleshooting section of several TSBs as well. Must be over 80% SOC....

So sometimes this is why updates don't kick off for people until they're out and about and driving around. Well one of the reasons anyway...

Never has a battery needed to be far MORE than just strong enough to turn a starter motor over.

My Powerboost used to do what the previous poster says his does. And my battery was replaced last year shortly after I got the truck due to the TSB on the "door not completely closed" problem that was causing the drains. My battery finally quit while I was driving and I had to get towed. Powerboosts can be strange animals, Part ICE, part Prius, and very complicated by comparison to straight up ICE or a BEV Lightning.

I used to plug in my 4a battery tender if I was going to leave the thing for two days without driving it. When I would go to program things like the TRM recently..it would say it was at 50% from just sitting overnight. So I'd set the PL2320 to a 20A charge and go get a cup of coffee before doing the update.

I traded that last Monday when I got my Lightning. Please don't flame me when I say I'm glad the Powerboost is gone. It was only meant to be a placeholder until my Lightning came in but I really never like it cause of the mileage (19) and how complicated it seemed in that very busy engine compartment.

Just wondering if everyone who has a job1 truck with a bed camera also has a crappy low resolution image? Also wondering if the job2 trucks are any better? If so do they use the same model camera or is it because of the 2 different ipma’s or both??

Job 1 truck here the relaolution is pretty rough here as well. I’m just hoping for the ability to select which camera shows up in the side card.

2022 here.
Only bed camera is in sidecard.

Which is fine with me.
I can get the hitch camera full screen if I need it.

Mine tested it and it passed their computer test and wouldn't replace it. I say it runs low overnight especially when cold temps. They say what the voltage was?

My bad battery was typically reading 12.3 to 12.4 volts and several times the truck would not start on the first attempt.

I made a USB drive for my truck and it finally kicked off and updated. The software update can now be turned on and scheduled. I kinda want to wait and see if OTA will work before I update the modules myself What tells Ford in the sky to send me updates. The last OTA update was in November and it locked the updates off.

You need to go out into the driveway and do something akin to a rain dance. And if the Fordgods find it pleasing, they will rain updates upon you.

The truck itself should notify the mothership. I don’t for sure getting off a stuck 1.7.1 will clear the failed update status with the mothership. Give it some time if you don’t get anything in a few weeks you might need to call the OTA hotline

Can someone check my VIN, 1FTFW1E89MFA78177

I have had PowerUp OTA 2.1.1 fail 4 times. Carried the truck to dealer yesterday. He replaced the battery and said he updated the PCM, APIM and TCU. He could not get the GWM to update.

Many thanks!

I think SSM 50289 applies to you.
Big Blue is working on a patch.
Have a look.

SSM 50289 - 2021 F-150 - Erroneous Diagnostic Trouble Code (DTC) U2404:92 Setting In the Gateway Module (GWM) After GWM Software Update
Some 2021 F-150 vehicles may exhibit an erroneous diagnostic trouble code (DTC)U2404:92 stored in the gateway module (GWM) after an over the air (OTA) update was performed or the GWM software was updated using the Ford Diagnosis And Repair System (FDRS). This may be due to various software parameters within the GWM.

If this DTC is identified during normal diagnostics, but the vehicle does not exhibit any customer concerns around the GWM operation, this DTC should be disregarded. This DTC does not cause any observable concerns or warning messages and does not affect vehicle performance or durability.

Ford is developing a software update which will be delivered to the vehicle via an over-the-air (OTA) GWM update in December 2021 to prevent this DTC from setting erroneously.

IMO, if U2404:92:0A is not a false flag in your GWM, then you might have an intermittent Ethernet failure between it and your IPMA which needs to be resolved, but I doubt that's your problem, because I would expect it to be more consistent since you bought it if it was.

Thanks for this information. Is this from FDRS, or dealer service corporate systems?

I am not sure what next/corrective steps should be.

I don't understand this comment " Ford is developing a software update which will be delivered to the vehicle via an over-the-air (OTA) GWM update in December 2021 to prevent this DTC from setting erroneously. " If the software update was developed and sent OTA in Dec 21, then why do I still have an issue?

Thanks!

First off, usually when Ford issues a statement about any sort of software rease date they are wrong by a several months or more. I don't know if there is a fix for this or not because software updates have little or no release notes.

If you don't want to wait and have to guess if a fix is in the pipe, I would advise taking your truck in for an appointment. Tell your service advisor you may have an Ethernet fault in the GWM but believe the GWM is simply corrupt.

Your shop can confirm of there is a legit GWM fault with a pinpoint test for this U code.

You may need your GWM replaced considering you what you said in other posts.

I talked to the dealer service manager after their repair last week. My truck had a weak % charge battery and he thought that might have caused the OTA GWM update to bomb out. He installed a new battery. This failed OTA update is being reset every 7 days. He said that if the next OTA update does not work, anticipated reset to be 6/14, he would update the GWM manually via FDRS.

With this possible software issue, I wonder if the manual update would work?
