AWD/traction /abs/pre-colliion errors all at once

[awscheetz]

I was driving home from Chattanooga a hour drive home and on i-24 it's a decent incline, had cruise control on at 65 mph.

Car went by me and then all these errors popped up at once. I babied it to the closest gas station and shut it off. I then drove it the rest of the way home.

I plugged up a code reader and it says left rear vehicle speed signal malfunction.

I check my dealer and they have a 3 week wait. The part is $7.99 though. So I replaced it. Still having the same errors.
Tested the signal with a oscilloscope and signal looks good. Until the error pops up then the sensor shows max feedback. No square wave when error is displayed.

My errors are AWD disabled/restored that randomly come and go.

Abs fault, Hill assist fault , traction control fault, pre collision not available

I currently have 8,000 Miles and it happened all at once. I seen someone having. Similar issues and they had broken wires from a rodent
I have looked and I see no issues, no broken wires or anything damaged.

Is this the type of error that you saw?
I have them one day while driving in cruise control on a road under construction with very unusual sharp curves and sudden drops. After i restarted the vehicle the messages were gone and saw a notification in my ford app

So first my dealer has had the vehicle for 2 weeks and can't find the issue. They *think* it's a broken wire somewhere.

Then they said it was becusee I changed the wheels to the other Ford wheels offered.

They are trying to do this to get out of a warranty fix. I need my truck. This is getting stupid. I want my truck and fixed.
