Multiple dash lights and fault messages

[Grayghost$$$]

Well........... it was a great first month and 1600 miles with my new 26 RR. I've been having a blast driving this truck from day 1. Coming from a 2017 Chevy ZR2, and a 2024 Silverado when I thought I needed a full size, this truck is a blast to drive and puts a smile on my face every time I drive it. That was until 2 days ago. I was leaving work, feels like temp is 105, so I use the app to start the truck and get it cooled down a bit. Hopped in the truck and while closing the door the engine stumbled and died. I pressed the start button to shut it down and restart. After the start, all of the amber traction, SES lights came on and the fault messages (Advanced front lighting features, Park brake limited function, Hill start assist, Pre-collision assist, Service advanceTrack, Parking sensors fault, Blind spot system, and Cross-traffic system, started rolling through. I shut it down again and during the start it was the same. I was able to drive it home and put my code reader on it. Got a U0415-00 Invalid data received from antilock brake system control module, U3001-89 Control module improper shutdown, C0037-64 left rear wheel speed sensor, U0131-00 Lost communication with power steering control module, U0151-00 lost communication with restraints control module, U023A-00 Lost communication with image processing module, U0401-86 invalid data received from ECM/ PCM, U0415-86 invalid data received from anti-lock brake system, and B1385-82 Oil level lamp circuit failure. Scheduled a appointment at my local dealership yesterday and of course on the way it went back to normal. I purchased the truck on June 15 and the service writer mentioned that there was a history of many faults from the 14th and 15th. When I went to test drive the truck on the 15th it was in the showroom. Of course the shop is backed up and gave me a heads up it would probably be a couple days before they could look at it. As a past GM tech, I know this is probably going to suck to track down. Just hoping they don't have to rip half of the truck apart to find it. Oh, and as another kick in the jaw, when I got home from dropping the truck off I get notification that my Procal had just arrived at the dealership.

When I got a bunch of seemingly unrelated errors upon startup in my new lariat (last year) it turned out the battery had low voltage, which was odd because my truck hadn't been sitting much at all. I put a new odyssey in and it's been fine ever since. Edit: I'll add that the original ford battery took a charge and seemed to hold it, but when I did a proper load test it failed. I never took it to the dealer because I just wanted a battery I can trust in the harshest winter conditions, and a ford battery just wasn't it for me.

Got a call from the service writer, said they found the right front wheel speed sensor connector was not clipped on. Said they are blaming all the issues on the ABS module getting a dirty signal and basically sending bad information to other modules. Time will tell, but I'm glad they didn't have to start taking stuff apart. I was thinking wonky battery voltage due to battery or connection somewhere.
