<TSB> Inoperative FordPass With DTCs U0146:09, U2402:00, And/Or U2402:92 - Built On Or Before 13-Dec-2022

[MidniteMayor]

I saw this TSB tonight on Ford.com -> Support -> Technical Service Information (https://www.ford.com/support/service-information/) page after searching using my VIN I have been losing Ford Pass functionality & vehicle connectivity about once a week on my 2023 Platinum. I've been working around it pulling fuse 32 in the Body Control Module Fuse box. I am considering taking in for service due to this TSB but I don't have high confidence in the dealership service department's ability to update the necessary firmware correctly.

Can the TCU be updated remotely too?

Can the TCU be updated remotely too?

Yes. TCU and GWM are the two easiest modules to update.

Yes, they can be updated remotely.

However the issue this update is solving is the TCU and GWM losing connection to the cloud, which means they cannot receive the update OTA.
BUT, if the modules were to be power cycled (via pulling the 12v or the fuse) they would then be back in communication with the mothership and able to receive the fix. Or at least until they lose connection to the cloud again if the update didn't get pushed in that window of time.

So then you are back to deciding if you want to go to a dealer for the update or keep manually rebooting modules until you get the OTA.

To ask a very dumb question (because I would love to avoid my dealer at all costs), how do I know if I receive the update OTA? Dealer said it would be over 2 weeks till I can get in so I'd rather just reboot my truck over and over till I get it.

There are dumb questions but if you are genuinely trying to learn then it wouldn't ever be a dumb question

because I would love to avoid my dealer at all costs

Don't we all?

The fix for this is packaged along with the update that includes the new user interface, so it will be very obvious when you get it as everything will look different on your Sync screen

Ford chat says my vehicle isn't affected and even if it was, they couldn't push an update over the air since updates are done in "random VIN group order."

Anyone have FDRS in San Diego and can help me update manually?

 

[HaroldCal]

My truck is at the dealer right now for this issue (2 weeks as of today). Hopefully this TSB being issued will get them on the right track to resolving it, and get it back to me. It's really grinding my proverbial gears having such an expensive and new truck, and having to put gas in a beater rental. All while paying for insurance and registration so it can sit in the dealer's back lot.

Whooo-saahhh.

Heck, maybe them having mine in the shop contributed to the issuance of the TSB. Let's hope. I mean, you're welcome, peasants.

My Ford pass worked great until 2 weeks ago. I pulled the Fuse 32 the first time and it instantly reset the modem and Ford pass worked again. I got an unrelated "Stop Safely Now" error starting up the truck. Luckily it didn't come back on later when I attempted to restart the truck.
Again, yesterday Ford Pass stopped working in the middle of the day.

Long story short, I'm not too comfortable resetting that fuse again. I don't think its a good solution.

For the meantime its back to using the keyfob and hoping it resets itself at some point with an OTA update.

I spoke with the shop foreman at my dealer today (my truck is there for this exact issue, among a few other minor ones). Last I had heard (last week), they had a whole new telematics unit on order. And who knows how long that would take, and I don't expect it would actually fix anything. But I made him aware of this TSB, as it seems quite likely that this is the TSB that is going to fix my issue, and get me my truck back.

hopefully they can get it done tomorrow? Seems like a simple fix with the software.
Keep us updated.

FordPass stopped working for me too. Hopefully this will be an OTA. I don't want to fiddle with fuses if there's no guarantee.

Have you tried rebooting Sync via the steering wheel buttons or battery disconnect/fuse ?

I definitely don't want to mess with fuses, but I'll try the reboot next time I get in the truck.

Mine is the 12" screen, so from what I've read, I need to hold the power button and Right Seek button on the dash, rather than the steering wheel.

 

[Grumpy2]

page 516 for 12" screen:
REBOOTING THE CENTER DISPLAY You can reboot the center display using the controls on the steering wheel. 1. Simultaneously press and hold the seek forward and audio system power button for 10 seconds
