Reset LVB to start receiving updates?

[Poorpilot]

Hey there,
I wanted to see if anyone has unhooked the LVB to see if it would trigger updates to start downloading? I purchased my 22 Lightning used with 1700 miles. The last update it received was 3.5.4. I have good ATT coverage and the Mach-e is Parked next to the f150 and it is constantly downloading updates. I saw some talk of unhooking the LVB to reset the system(but wasnt sure if that was for downloads or installs), but wanted to see if anyone actually had luck with this fixing the problem. I called Ford and they said that there are no updates pending . I dont have PAAK nor the new UI. My truck was originally a June delivery it looks like. Thanks

I have tried LVB reset multiple times. . Just did it again tonight. It didn’t do anything. I am also on 3.5.4. Update pending. My software update page in the truck doesn’t have any settings for scheduling etc.….nothing. Just says that I have update pending but no way to make it happen, schedule it, turn on/off auto updates
no PAAK, MAY 30 Build.
Feb 3 was when I finally updated to 3.5.4
i have full att coverage, had Wi-Fi access point installed next to where truck is parked. Plug it in most nights.

So there's actually more you should do to attempt to get it to update. I'd say one of the most helpful for me has been a Bluetooth OBDII dongle which has allowed me to precisely monitor the truck's perceived 12V battery state of charge.

But regardless of if you have a dongle and an app to allow you to monitor it, there are steps you can take to greatly improve your odds of updates installing properly. It all relates to the 12V battery:

1. Start the truck, disable the Power down timer and let it run for at least an hour, but longer is even better.
- this charges the 12V battery. As stupid as it is, the truck seems to not maintain the 12V battery above 75% when not running. The "major" updates like the DTE require 90%+ SOC on the 12V battery before they'll even attempt.

2. Reset the 12V BMS. Contrary to conventional wisdom, simply disconnecting the 12V doesn't reset the BMS. It actually requires a specific procedure. But good news no scan tool needed.
A. Turn the truck on to accessory mode (press the start button without depressing the brake pedal)

B. Pull the lefthand steering column stalk back five times in succession to flash the high beams.

C. Depress the brake pedal three times in succession.

D. Look closely after the dash where the 12V battery icon is in the bottom right corner. After 5-10 seconds it should flash several times. Your BMS now reset!

3. Disconnect the 12V battery. After the BMS is reset, sometimes some issues can crop up, potentially due to some disparity between stored values and the current BMS data so after starting the truck post BMS reset for at least 10 minutes, disconnecting the negative terminal, waiting 5-10 minutes and reconnecting can solve those issues.

After these procedures, go ahead and try to manually initiate the update and see what happens! It still might take a couple attempts, but you'll definitely have a way better chance of success!

Hope this helps!

Then do the hokey pokey and you turn yourself around.

I will give it a shot but it doesn’t look like my truck hasnt even downloaded anything to install. All ford connected functions seem to work otherwise

If Ford looked up your VIN and said there is no update pending, then there is no update pending...

You can also look yourself on Ford.com on your computer, by looking at the code on the site. https://www.macheforum.com/site/threads/ota-update-status-hidden-in-the-ford-website.12367/

i connected the LVB to a battery charger for a few hours. I followed the reset procedure. The pending update has completed overnight. This happened automatically, I still don’t have access to any type of settings within “Software Updates” to manually initiate an update.
thank you for sharing this procedure.

This is all BS! Ford needs to make updates happen under normal driving conditions, without having to go through a 12 step program! My 2022 Lightning Lariat has tried to update software more 10 times over the 6 days, none were successful. I have auto updates on, 6 auto try’s and I tried several manual downloads none were successful. Called Ford, they say it’s a battery condition issue. They recommend driving around to charge up the battery or take it to the dealer. I call BS on Ford. My Tesla updates regularly without any issues. If updates fail, Ford messaging should tell me why it failed. All I get is a message that the update download failed and to try again.

That's in one of the updates.
