Got my '19 Limited stuck in the yard last night (tried to flatten some ruts but it was just too slick). She wasn't buried, just too slick on some straw and mud to back out.

While slowly trying to back up, the dash lit up like a Christmas tree. It hit all at once, the biggest thing is it wouldn't shift back to 4x4 and I had to have a neighbor pull me back the 10ft to the driveway!

Zero issues before this, put a new battery in a few months ago. I disconnected the battery for an hour last night and then plugged it back in before going to bed.

Fired up the truck this morning and it's still doing it.

No codes are popping up. Is anything I should check or is it off to the dealer I go (an hour away).

When you did the battery disconnect reset did your truck have full visibility to the sky? i.e. was it outside all night? My experience has been you should do it that way. Not saying that is your issue whatsoever. Just asking.

It did not, it was in the garage when I pulled the negative cable and stayed in the garage after I hooked it back up.

If it was good till you went out in the back yard and flung a little dirt up underneath and some wet stuff one of you abs connectors might have wear on it and now is wet , I would try the battery again , but also crawl under and do a good inspection.

I have had this 3x on my 2025 3500. First time I noticed was after window tinting. Shop claimed all those lights were on when they got in it. Disconnected batteries to try the old middle finger electrical salute. Didn't work. Whatever, was near dealership so headed that way. A jaywalking moron forced me to slam on brakes and all but CEL went off. Dealership pulled codes and only one was P2509. There was a TSB for that so they reflashed it. In and out in 45 minutes.

Last week hit a chug hole right before I parked and shut down truck. Restarted and Christmas tree again. Off then back on and CEL with all the speed sensor stuff. Drove a little bit and slammed on brakes...all lights cleared. Got home and hooked up code reader (U1412) and cleared CEL.

Yesterday was on way home, and dash lit up again. Tried several hard brake cycles. Nothing. Shutoff and restarted(CEL appeared)...2 more hard brakes. Lights stayed on. Then miraculously all lights went off with normal driving. Got home and U1412 again. Cleared it.

Gave up and taking to dealership next week.

It seems there was some mud and straw stuck behind the wheels that I didn't see.

15 minutes really spraying it out, pulling the battery cable again and it's all good. Now to let it finish booting up overnight.

Maybe try it this way:

The procedure goes like this:

1. Park your truck outside so the shark fin has a clear view of the sky and turn it off. Have your 10mm open end wrench in your pocket.
2. Pop your hood open and get out and close your doors.
3. Disconnect the negative terminal of your battery and leave it disconnected for 30 minutes. Leave the truck alone during this time.
4. Reconnect the negative terminal and again LEAVE THE TRUCK ALONE for 1 hour. Do not open the doors, nothing.
5. After the hour expires get back in and treat it as normal. All your screens should be back to normal and the re-init is complete.

The only thing I lose when I do this is the theme settings. The dash colors and fonts go back to the default for me. Everything else remains, like Sirius presets, phone pairings, and all your other custom settings you have made.

Maybe it will make a difference for you.

It's fixed, apparently I had some mud and straw still stuck in there.

A ten minute battery reset and the warning lights were gone when I fired it back up. She spent last night in the garage and everything is back to normal now.
