The Active Grille shutters are controlled and monitored by the PCM. Disconnecting or removing them will generally not cause a CEL, since they are not engine performance/emissions critical. You will, however, have DTCs stored in the PCM.

Their purpose is to improve engine warmup when it's cold, and increase airflow to the heat exchangers when warm.
Very important info, thx
