  • Unfortunately, other than the Active Grill Shutter Assembly I have not seen any other component setting the P1D73. I also checked a national database of repairs for your model year and there is nothing else. Your next step is check the wires from the Active Grill Shutter Assembly to the Power Distribution Center. Also, make sure the Active Grill Shutter fuse is OK
