I figured it out, the bull bar was actually blocking the ACC sensor, so I moved it higher. No problems now! I my needed to drive a couple days to recalibrate
So my truck came with ACC, but I've had to relocate it after getting an aftermarket bumper. I get that "Collision Assist Unavailable" and cannot use cruise control or ACC. Thought I'd be able to just connect to FORscan and run the calibration procedure. But I cant even find the CCM...thoughts...
All I needed was the 4 pin molded deutch connector. I decided to modify my current harness. 41 dollars each for those diodes ? I also have an assortment of deutch and molex plugs and terminals, also wire for days. I'll be set once they arrive.
@beaver24 - have you had a chance to take a nighttime vid of the headlight operating? Its been cold by me too and going out to take a video lately sounds terrible so I completely understand if not.
