Eh, its just a beauty ring but if something knocked it out then maybe the eyeball aim was affected. I had "unavailable" errors but dealer said it as aimed a tad too high and they say they adjusted aim down and I have had no error since.

Re: Forward Collision Warning Problem

So, here an update, no code can be find in the system and the sensor is aligned, so right now to wait FCA has a fix.

It actually does appear to be part of the antenna system.. my guess is that the antenna pattern gets some nasty sidelobes from the nearby plastic parts if it isn't there.. many people here and over on the durango side have reported that things don't work well without that trim piece..

Those often have either RADAR units built into them (so they can be used as "Slow Down!" signs) or what's known as a "Safety Warning System" (SWS) that is meant to work with more recent RADAR detectors to warn you of construction zones or stopped emergency vehicles.

The system was never fully implemented, so it's not universal. As a result, it's rare to run across it. However, when I used to ride with a RADAR detector, I would get occasional chirps from it when approaching construction zones in some places.

It's possible that system is built into that information display that was on the right side of the construction area and it was sending on a close enough frequency to your own vehicle's RADAR to confuse it.

Duh, u r definitely correct. That cheapo plastic beauty ring with its concave shape is definitely part of focusing/collecting the outbound and/or return radar signal. To what degree who knows bit more than just a cover.
