C1AC1, U0232 error code

Hey Guys, I've got a 2019 trd pro I just purchased. I'm getting a pre collision system malfunction warning on the dash. The warning doesn't appear/beep till the truck moves about 20 feet. When I scan the obd2 I get C1AC1 (master module horizontal axis misalignment) and U0232 (lost communication with blind spot monitor slave module). Also, the pre collision system off symbol is flashing on the dash.This truck was hit from behind but the bumper doesn't look crooked. Any insight?

 

Blind spot module is back there and was likely hit.

I would try to calibrate it first and see if the code clears.

it’s a special dealer radar cone, you can’t do it at home without it and a tech steam.

 

Here’s the procedure for the BSM calibration.

 

Sounds like the sensor was damaged or wiring to it damaged. They are very sensitive, even ice build up and sometimes water will throw them for a loop.
