2018 Multiple Warnings on Dash and loss of power

I have a 2018 SR5 TSS and just the other day the truck suddenly threw a bunch of warning messages. Traction control error, trailer brake error, pre-collision error, stability control, cruise control, and it says all my tires are flat even though it shows over 40 PSI in each tire. Occasionally, the truck will lose power for a bit and then "surge" back to normal power suddenly a few seconds later.

I tried resetting the ECU and that cleared up the issues for a little bit, but they came back within a few miles.

I can't find anything like this really on the internet. There's one complaint of a Camry doing this with no resolution, the car had less than 1k miles so the dealer just swapped it out for them. There's one complaint on carcomplaints.com and that's all I can find. Just hoping someone had some ideas.

 

Have you inspected for rodent damage?

 

I don't see any evidence of electrical system damage with an inspection mirror and climbing under the truck. I did find the mounting brackets on my driver's side headlight are cracked, no electrical damage though.

I was coming out of a rather steep parking lot when it happened the first time and I do a lot of ranch roads in the truck. My fear is that a CANBUS line somewhere got fatigued and now has an intermittent connection.

 

Have you checked your battery?

 

Engine codes would be the place to begin...

 

12.6VDC when off. 13.89VDC while running. It cranks basically immediately, just like it did when new. My cheap little meter only handles 2A or I would have checked those.

 

I assume there's not a way to pull the codes without an OBD tool? Honestly, the last motor I worked on extensively and rebuilt was a 2010 GSXR750, and then I got out of motorcycles as a hobby when I totaled it. So I know motors and all, but car/truck specifics I'm probably not sure on.

 

Had similar issue twice, cleaning out the trailer plug connector fixed mine.

 

Checked the plug but it was clean, aside from a bit of sand. I wiped them out anyway, no change.

When places open tomorrow I'll get it scanned somewhere and update the thread. Thanks for the suggestions so far guys!
