If the 12 volt battery terminal is disconnected or the No. A18 (10 A) fuse in the under-hood fuse/relay box is removed while the power tailgate is operating, the power tailgate will not be able to open or close automatically until it is reset. To reset the system, fully close the tailgate manually. Once the 12 volt battery terminals are reconnected or the No. A18 (10 A) fuse in the under-hood fuse/relay box is reinstalled, the power tailgate system automatically resets. Make sure the power tailgate operates properly.
