Code P059F 2015 Chevrolet Silverado Description
The dual active grille air shutter system consists of two aero shutter mechanisms located in the front grille for controlling the amount of air flowing through the grille. It includes three wires; ground, power, and a Local Interconnect Network (LIN) Bus serial data circuit from the ECM to the shutter actuator. The ECM determines shutter state based on various vehicle conditions such as vehicle speed, coolant temperature, fan state, refrigerant system pressure, A/C compressor state, and ambient temperature. The ECM has the ability to command each shutter individually to the open or closed positions through communications on the LIN Bus.
The actuators are powered by an ignition circuit that is active when the key is in the RUN position. The vehicle may have to be driven for up to 13 minutes at speeds greater than 41 km/h (25 mph) before a shutter begins to move. If low ambient temperature is detected, the shutters will remain in the closed position.
The Diagnostic Trouble Code (DTC) will be set if the desired Active Grille Air Shutter Position achieved has exceeded the number of attempts.
