OTA Update not working?

[Chris]

I’ve tried doing the over the air update on my F150 about 10 times and it never updates. It is the Ford power-up o 2.8.1 and in the vehicle it says it would take about 145 minutes to update. I’ve never had an issue with any other over there update before. I’ve tried this update with the truck parked in my garage and connected to Wi-Fi and it did not work. I’ve tried this update outside with Wi-Fi off and that also did not work. Is anyone else having this issue? Screenshot attached from the Ford app regarding the update. I followed all directions making sure all doors are closed vehicle secured no lights are on etc. I keep getting an error message saying it will try again at another time. I’m initiating the update from the truck clicking update now and then turn it off and lock in the vehicle. I promise I have followed all directions so that’s why I want to know if anyone else is having an issue. Thank you

Its your battery; while it has enough juice to crank your truck it doesn't have the power to let the update run without getting dangerously low. Get a solid battery charger and keep it on charger over night. It will update, almost guarantee it, tons of successful outcomes doing this.

@Ford Motor Company you really need to let the driver know that the update failed due to a low battery. It'll show this in FDRS, but not everyone is using that, make it show it over the Fordpass app or in the truck itself.

Do you happen to have any recommendations on a battery charger or brand? I don’t know much about them. Never had to deal with this before. Thank you

I wonder if something like this would work. Hook it up to give it extra juice if needed.

this is not what you really need for updates. These are designed for short bursts of high amp discharge. OTAs need low amps for long time periods.

I have the same issue with 2.8.1 in my 21. I've met all the conditions required of the update. I've never had an issue with any other update. I've placed the battery on a trickle charger to fully charge the battery with no change and see continued failures at my scheduled update time. I've also manually tried the update right after fully charging the battery with no change. I've watched the screen and the last messaging that appears is a Preparing Update message then the screen goes black.

Any help or assistance would be appreciated. Thank you!

I’m glad I Read this before purchasing the battery charger. I’m wondering if there’s a separate issue with this update. I’ve experienced everything you just described with the preparing update and screen going black. I manually try to update everyday hoping Ford somehow fixes the issue. I will probably have dealer handle it by the next oil change if it doesn’t end up downloading by then.

I tried using one of these as a 12v power source to bench program some controllers. It didn't work because they turn off after a short period of time.

Finally got mine to update. Parking brake on, trickle charged the battery, headlights to off, locked the truck, disconnected the battery for 15 minutes then it updated.
