So I have replaced the trailering mirrors on my XLT with standard mirrors. Everything on the mirror works, camera 360 view and lights. However, when I went to back up a message popped up on the dash stating reverse breaking is not available, contact dealer. I pulled the codes with Forscan and found a B1578 in the IPMA, indicating 360 calibration is required. I've read several people changing the mirrors without incident. Is 360 calibration truly needed?
