A shutter system for controlling an airflow through a grille opening in a vehicle includes at least one louver. The shutter system also includes a mechanism configured to select a position for the at least one louver between and inclusive of fully-opened and fully-closed to control the airflow through the grille opening. The shutter system additionally includes a slave processor in operative communication with the mechanism and a master controller in bi-directional communication with the slave processor via a single wire. The master controller is adapted to control a selection of the position of the at least one louver by commanding the mechanism via the slave processor using solely the single wire. The slave processor is adapted to respond to the master controller using solely the single wire. A method of controlling operation of an adjustable shutter is also provided.
