24-PU0121-FTDI-FX Update - Battery Optimization + Battery & Remote Start Enhancements

[CarGuy11]

So, it did work fine after I redid the FORScan codes. However the forscan codes looked the same as before. So not sure if maybe i missed the sensor when i waved my foot underneath. It does work after the update and Forscan Flash

Ok I haven't received the OTA yet. So same codes worked then?

Yep - everything is the same. Which is good very similar to what happened with the IPC update and the power meter if you did that one

AKA "Update Not Successful" message because the 12V battery died during the OTA and you now have to get your car towed to the dealer to fix the software and unbrick. The car cannot be driven in this state.

Having your car brick is not "nothing" to most people.

Bricks are something you throw away or are only good for a paper weight not something that can be fixed.

So what you are saying is that resetting it so it keeps the 12V at a higher SOC will make this happen? That makes no logical sense. I guess resetting sync could cause it to brick somehow also? We are talking about increasing the 12V soc which should do the exact opposites of what you are saying.

I have no reservation about resetting anything and have never had a problem to date doing so. Your failure has nothing to do with the 12V being at a too high a state of charge, it is just the symptom of a poor 12V BMS and that the OTA process is totally dependent on the 12V for power and uses nothing else.

When they install in the shop they need a huge 12V power supply hooked up to do so and do not count on the 12V. That also has nothing to do with resetting the tiny 12V battery and is just a problem with Fords update process.

This update seems to have made the car ignore the charging limits that I set here at home. Overnight the car charged to 100% despite the 90% settings I have. And, these are verified in both the Ford Pass and the settings in the car. Ford gives and Ford takes it seems.

You clearly don't understand the details of how it works, and I'm done trying to explain it. If you tell the computer the battery is at 100% (by resetting the BMS) but it's actually at 35% capacity, that's a problem. You'll run out during an OTA. Have fun calling the tow truck then.

That’s normal after some OTAs. Charging schedule gets cleared until the next time the car is turned on and can download/sync the schedule with the cloud.

I did drive it after the update, so it was turned on and off, then plugged in after the update.

I got this update OTA yesterday after driving home from work. 20 minute inhibit. I went for a 20+ mile drive , then another drive back afterward. I have not connected the car to L2 yet. I expect that my charging schedule and limit will be in the car when I do charge it. ?‍?

That is not how it works. I reset it charged it to 100% with a 12V charger for 2 days and the voltage says it is 100% now not 35%. I guess Ford could have made the car that stupid but I do not think so.

Double post as Edit may not be in order? Clarify.

My guess is Ford has a Voltage vs SOC graph for the vehicles 12V. Normally SOC is based on the batteries voltage. That is how it determines it not by resetting 9V to be 100%? Maybe that is what Ford is doing but I don't think so? I know for mine the voltage matched and was good after but have stopped checking it now.

It's still failing on bad data quality. Not sure what's up, a forgotten app (perhaps used in the past) might be pinging your car or you could have an excessive 12V standby drain. At this point you can try the BMS reset in the failed OTA guide, followed by another 8 hour rest period before attempting the OTA again.

It finally installed!!

I used the Blower method for 2 hours, and got the 12V to 94%, then did the BMS reset, and left the car undisturbed for 8 hours, then did the Blower method again for another 2 hours, and got the 12V to 100%.

I hit the Update now option, and it finally completed the update!

I hope I don’t need to go through all these hoops for future updates!

Makes me wonder if when the dealer changed the battery 3 months ago had something to do with it. And the BMS reset is what was needed. I was able to get the 12V to a high level and had left the car undisturbed on previous attempts. Seems like only after I did the BMS reset and made sure the 12V was high it worked.

FWIW, I received this update on March 27th and didn't lose my kick to open function.

 

[CarGuy11]

Hmm, I didn't loose my handsfree tailgate Forscan change after this OTA. Aug '22 build received 4/8.

My car stopped charging right at my limit this morning. Nothing to see here. ??
