My 05 Ultra w/PCS was in its first snow storm last night. As the storm worsened, a bright red triangle warning light appeared on the panel and the display read "PCS Not Available At This Time." I had read about this possibility in the owner's manual, but was still surprised when it occurred. The interesting thing was the radar cruise control seemed to be unaffected by the snow. Obviously, I didn't set the cruise control, but I had it on and didn't see any messages saying that it was unavailable. Anyone else have this experience?

 

i remembered driving in heavy rain / fog a few weeks back, and i was using my radar cruise control.

as the rain and fog got progressively heavier, the cruise control decided to give up and said it was not available.

but nothing with the PCS.
