Error Message

I just started seeing on my instrument display screen (for lack of better words) “radar cruise control unavailable-clean sensor”.Obviously because I live in the DeepSouth, the weather here is very mild (for winter). Also my truck is garage kept. If anyone can throw me a bone of wisdom, I’d greatly appreciate it.
Thx

 

Welcome to TW!

 

Might be worth having a dealer look at? It may be mentioned somewhere in TW as well

 

Check the radar sensor cover for bugs and other debris. It's literally telling you what to look at and do right in the error message.

It will also do this in heavy rain. Basically the radar system knows when it should expect a return on the signal that's being broadcast. If the signal returns immediately (bouncing off debris that is stuck to the sensor garnish\cover, or even heavy rain) then it throws an error because it can't do it's job if the signal doesn't actually leave the vehicle.
