Collision System/TrailerBake/4WD blinking

Coming home today ran over a strip of semi tire couldn’t swerve both lanes occupied. Made a pretty good thud underneath then all lites came on front collision warning, trailer brakes, 4low. Runs and drives fine still can’t see any visible damage. Any ideas?

 

Wheel speed sensor damaged?

 

Brought it to dealership this morning they couldn’t get to it so crawl under when I got home from back to front with flashlite I can’t see any physical damage.

 

Most likely a wheel speed sensor. Look at each of the wiring harnesses. They may have gotten slapped by the road rubber

 

10-4 I will take a look. Thanks

 

You were correct my friend the passenger side rear wheel sensor broke off The two wires were sticking out so plugged it back in to see and all lites went off. Will order new one and replace. Thanks again!
