Hey fellas. Anyone try to use the Active Grill Air Shutter actuactor test using 16.2 or so? I'm trying to test this silly grille BS on a 2013 2.5 Malibu using Modis Ultra and all I can manage to get every time is "Requirements out of range". All codes cleared, none reset, actual and commanded for shutter are both 100%. I can't prove-out just driving! It seems conditions not right to run monitor (too cold here). Anyone know how to force operation of this shutter or why this bi-directional control won't work? S.O. tech support has no advice and I found no TSBs or bulletins. Thanks
Neil
