I was sitting in my Yukon the other night while my wife went into the store. I had opened the door to get out but I ended up sitting there while she went. Then all of a sudden my gauge started scrolling. This is with the keys out of the ignition and doors shut. It went from odometer, hour meter, then this. 
Has anyone seen this or know what it is?
