All safety systems getting disabled when cold and wet?

[R8er]

Second time now this has happened to me. The first time it happened I sprayed off the truck to get salt and other grime off the suspension and so forth. After a few hours I drove to the store... when I came back out to my truck and started it, I get "Pre-collision Assist not available" great.. Then I get more... basically all the safety systems get disabled. Even cruise control assumedly because I have adaptive cruise control.

Second time, we had wet slushy roads... drove about 20 minutes (again to the store) with the slush splashing around the whole way. There was quite a bit of it so under carriage got trashed with it... Came back out to truck... and again, all the warnings. had to drive home the whole way without any safety features. Basically everything gets disabled, even ABS. ABS light comes on too; tested this and sure enough... no ABS activated.

I'm not even sure how this is even safe is my whole rant.
Anyway, does anyone have any clue? I pulled codes with ForScan and it just had the 'Bad data from ABS module code'
There are multiple modules giving a U0415 - Invalid Data Received from Anti-Lock Brake System (ABS) control Module.

Code is being thrown by PCM, RCM, PSCM, and IPMA.
Its been 5 days as you can see from the dates, but hasn't happened again but I really haven't had the same conditions either.

Thanks all, I just wanted to get this somewhere for you to see and get a little bit of advise. maybe I just need to take it in and check for FDRS updates or something. Starting to think this truck is turning into a real stinker.

Pre Collision Assist is very common. I think that is the sensor that is behind one of the big rectangles on either side in the front. It gets snow or ice or slush on it, and then becomes "unavailable", until its cleaned off and works again.

The other stuff is not. Michigan is just as snowy, but I've never seen that happen, so sounds like water is getting somewhere it shouldn't be. Sure I'll get the occasional corner sensor locked red, but again thats snow and ice buildup on the outside, very rarely something else.

I had this same basic issue last week. Ironically had the most problems the day after going through car wash. Started with parking sensor issues, then went to ABS, then traction control, then held descent.

I had three different codes. They all disappeared after about four days. I still have a U211B-51

so just to reiterate for mine, there was absolutely zero ice, zero dirt, none of these sensors were covered.

Mine was in no way shape or form a battery charge related issue either. Main battery was 12.8, aux battery was 12.6. Once started I was seeing 12.8.
