2021 Screw Tremor. Everything was fine earlier today, but just 30 min ago I tried the auto start in my driveway...wouldn't work. Tried to unlock w/the fob and by touch...wouldn't unlock. Used the actual key to unlock the drivers door.

Started it up and all sorts of stuff has a fault, rear seat belt, terrain management, pre-collision warning, touch screen won't turn on, adjustable mirrors don't adjust, wrench icon...and a few others that I can't remember. Truck runs fine, took it around the block, not in limp home mode.

Things I've tried:
1. Took the negative cable off the battery, let sit for 5 minutes...reattached, same issues.
2. Tried using my code reader to see if I could clear things...OBD2 port isn't working, tried two reading devices.

Any ideas? Can't even lock it up...well, I can lock the drivers door. The lock unlock buttons on the doors don't work.

Thanks,
Craig

If I had all these issues, I would go to dealership to make sure it's been detailed for future problems etc and have them fix it up. Probably something to do with the battery but you already know that..

Starts and runs fine, HVAC is working, controls for that work...although I don't know what the temp is set to because the touch screen won't turn on.

I can turn off and on auto start stop, but the light on the button doesn't come on.

Drive it to the dealer.
Before you have to have it towed there.

Maybe check if wires have been bitten through anywhere? I think RP and Bret might be onto something :p

Try the battery disconnect for like 30 minutes. That way the systems are all down for sure. I would still take it to a dealer and get the issue recorded in their system so if down the road there’s more problems you got a record of it with them already

+1 on disconnecting the battery then waiting a bit. When in doubt, don't scream and shout ... do a reboot ... LOL.

I had similar issues with my trike. Weird electronic stuff. This was my first trike/bike with a can bus ... checked codes and all of them were "low voltage" on various things. Trike started, ran fine, just the weird electronic stuff.

Did the disconnect, waited, rebooted ... electronics were fine for a few minutes, then they all came back.

Then take it to the dealer. Although, be prepared for big wait on any parts ... :blush:

Taking it to the dealer is kind of a last resort...the one I bought the truck from is 50 miles away (and in MD traffic about 2.5 hours)...the ones closer won't give out loaners if you didn't buy from them.

I wish I could check for codes...both code readers won't even power up w/the engine running.

Battery has been disconnected for about 15 min. now...I'll wait another 20 and try again.

Thanks.

Did anything show up on your Ford Pass App? A time or two when something went wrong on mine, I got a message on the app.

30 min battery disconnect didn't do anything. Add to the list that the windshield wipers won't turn on.

Checking fuses now.
