Recently been trying to get the PU1009-mil-dte update but the truck won't do it. Long story short, been going back and forth with Ford chat via the FP app and the trucks 12 volt battery is apparently saying that it isn't charged enough. They had me drive it for 30 mins and try again, didn't work. The next Convo resulted in them telling me to make a service appointment. Appointment set for the 6th of Feb. I chatted with Ford 4 times about the issue and tried manually kicking off the update as well as the scheduled update attempting it but no good result. Anyone else experience this? Have a solution that doesn't involve a trip to the service center?

40 threads at this point, I think. Search 12 volt battery.

Sorry, new user. I did search for it but I must have done something wrong as I didn't see any results that really focused on it as a problem.

 

[R.I.P.]

"Death" by 12v battery is ubiquitous to modern EVs. IMO, it is an area even Tesla paid too little attention to while in the design phase (supposedly they are fixing that).

The problem is frustratingly simple. EVs do not need a starter battery, they can be readily charged via the DC/DC converter, so there is no need to put a very big 12v battery in the vehicle, right?

Well, these vehicle are packed with 12v systems that can beat on that little 12v auxiliary battery pretty hard. This problem is compounded if design relies to much on this battery, rather than pulling off the DC/DC once the battery has fired the HV batt's relays.

The Elegant solution is two-pronged.
1. Spend a little more money on the auxiliary battery. Some manufactures are promising that they will go to a lithium battery for the 12v system.
2. Take better care of the 12v battery by limiting what can draw from it if the DC/DC is not running. This limits features of the vehicle while it is "off", so it not a popular direction with the designers.

My 2015 Spark EV does not have an elegant software set to protect it's 12v battery. The inelegant solution is a trickle charger pigtail:

Amazon.com

Anecdotal evidence would suggest that the Ford software is similarly inelegant. One of these pigtails might be equally handy as a "revival tool" for these types of problems with the Lightning.

So, consider putting a 12v charger on it overnight when the updates tend to push. This has helped some folks.

Yep. It's been posted here. To try to make sure the update works, drive the car right before the scheduled update time and plug in your EVSE to charge. No guarantee but these steps really help in cold weather.

Tried the driving before the update, that didn't work. Don't have a 12v trickle charger but could get one...but should I? Shouldn't this just work? I don't think I want to get into the habit of putting on a trickle charger every time it needs to update. Just seems wrong for a new, expensive truck. Maybe I'll try it though as an experiment.

 

[Kawartha Lightning]

I just hooked up a 12 V battery charger to the starter battery, left it on there for half an hour, and it updated right away after multiple failed attempts prior to that

 

[Spiffster]

Kinda wish the truck or the app would just let us know it could not update because the 12v battery was low. I guess this day and age too much info can be dangerous, IDK.
Anyway, I hooked up a Battery Minder to the battery and looks like voltage is indeed low:

Also, somewhat of a side note but why would I pull all the tabs to access the labeled jumper(?) points on the left side of the frunk when I can just hook into the battery itself? Lot easier to remove the cover and access the battery directly.

Agreed, I had to jump and ICE Silverado and did the same as you.

IIRC a future update will provide more information on why PowerUps fail. Of course, your truck will have to update to get this.

My truck finally updated this Power up after 30 days and 45 attempts. I did charge the 12v up to 95% as I had before and this time parked in a different location in front of house instead of driveway (still the same number of internet bars) but didn't plug in charge cord. I did turn OFF the light switch, which is what FORD recommended. I also scheduled a service appointment with the dealer and told my truck that information. It surprisingly updated that night during its scheduled update time. Maybe threatening your Lightning is your next step?

 

[Voltz]

IIRC a future update will provide more information on why PowerUps fail.

4.1.1 Release Note:
"You'll also now receive new pop-up alerts to inform you when a precondition is not being met so that you can take the required action to receive your update. For a non-drivable update, preconditions may include that your vehicle is parked, it's not running, all the lights are off, doors and trunk are closed, and you're not pressing the brake pedal."

It may be the coincidence of superstition, but I got two updates (DTE & 4.1.1) over two days after pulling the OBD II reader (and going for a long drive).

 

[Spiffster]

I attempted the update after charging the 12V, and it failed again. SOC on the traction battery was 68% and the truck was unplugged. I then plugged in the truck, let it charge for around 1 hour and attempted the update again. This time I watched the screen go through the update. The truck stopped charging through the update, so Im not sure it mattered or not that it was plugged in this time. Perhaps it wanted a higher SOC on the traction battery before it would update, or perhaps it knew I was watching this time...

I’m dealing with this issue trying to successfully get update done.
Do you think you could you just direct wire a tender on the battery & then plug the 110 end into the onboard power outlet inside the frunk?
….. just thinking out loud?!!?

I think you could do this, but what would be the point? As soon as you turn the truck on, the HV battery should be charging the LV battery, truck needs to be on to enable the 110V outlet in the frunk.

Sorry
I am at the dealership right now with that problem it’s been three hours and I’m still waiting for them to figure it out.
The has been updating on it’s own until now.
Was given the same information. (Low 12 volt battery)
Love the truck but this is ridiculous.
Good luck!

please let us know what the dealership says. I have the same issue, only 15 failures to update so far, so not winning this competition, but dang!!!!!!

 

[Dalpilot]

I’ve got a trickle charger on the 12v battery, is it ok to charge big battery at the same time?
