We are in Buena Vista Colorado. Today we drove from north of the New Mexico border on back gravel forest service roads to Buena Vista. A solid 30 miles was above 10k elevation. About half way the dreaded “service 4WD” idiot light comes on. It is the C140E-00 code. It stays clear. Am I good to drive up the mountain tomorrow or do I make a bee line for Colorado Springs and the local Jeep dealer?
