Code U0284 Cadillac Description

The active grille air shutter actuator closes louvers at the front bumper to enhance vehicle aerodynamics in driving situations where cooling and A/C loads are relatively low and high levels of front-end airflow are not required. If high levels of airflow are required, the active grille air shutter actuator opens the louvers. The control signal from the chassis control module, ignition, and ground circuits enables the active grille air shutter actuator to operate. If the conditions for opening the louvers are reached the chassis control module commands the active grille air shutter actuator to open the louvers.
