Traction Control Off

[Bahndvr]

Getting on the highway yesterday when I hear the chiming and look down at the dash. Traction Control Off, ABS On, Disabled Hill Assist, Drive selections not available. The steering wheel becomes hard to turn. It went away before I got home.
Came on again today getting on the highway. Drove through the car wash and a minute later went away.
Anyone know what that is?
Thanks

Note: it's intermittent

Spitballing here. Possibly a loose connection at the ECU in the passenger kick panel? IIRC, most if not all of the wiring harness for the various systems plug in there. Have you or anyone else been working in that area of the car lately? Or it could be something as simple as a loose fuse that goes intermittent as you drive. Check all the fuses under the hood and in the passenger kick panel to make sure none are loose.

I'd also find out which fuse(s) protect the power steering and ABS modules (or whatever they're actually called) and replace them. Couple of bucks for fuses vs. a really expensive trip to the dealer. Also, do you own a code reader? Plug in and see what trouble codes are stored.

Did you hit a bump right before things went haywire? Usually its either a rough bump or gravel to do that on my car. Happens infrequently but more than a few times in 5 years.

No bumps and no gravel.

Not been working in the area. Have installed the sequential tail lights plug 2 weekends. This does hiccup during the winter but never as completely shutting off All the traction stuff.

I will check for trouble codes.

Wheel speed sensor issue, in my case it was a worn wheel bearing but basically the ecu is getting mixed signals so disable all that. Even my reverse parking sensors were disabled by ECU

So if there was let's say an inch difference (~4%) in diameter size between front and back tires that could cause the issue?

yep another thread on here with gearing in the diff changed to a ratio the BCM couldn't be set for, only a tune resolved it

And I'm guessing that wasn't an idle question?

A lot of good information in that thread. I have a 2016. So looking through the thread looks like a torque management thing. Wow 1 inch difference between front and rear tire diameter size and everything goes to shit.

Pull fuse 62 or pull the plug?

 

[Bahndvr]

The error code that I have is: U0415 - Invalid Data Received From Anti-Lock Brake System (ABS) Control Module

Is it possible to capture wheel speed data?

Stock wheels are on and no change, everything disables so now I have to look for the issue.
