Only pops up after driving at highway speeds w/cruise enabled. Doesn’t seem to affect anything. No other warning lights appear. Goes away if vehicle is turned off and then on. Takes about 20 minutes to reappear after resuming driving w/cruise. I don’t have a scanner on me since I’m traveling out of state and this just happened on the road.
I quickly checked the brake fluid level at the last test area and level is good. Did some googling and only thing I could find was on the F-150 forum. Answer seemed to point to a vacuum line that’s a part of the vacuum assist system. Any help/guidance is greatly appreciated.
