  1. GRILLE SHUTTER SYSTEM 
    1. General description

      The swing grille actuator assembly receives signals from the ECM via LIN communication. Based on these signals, the swing grille actuator assembly operates the radiator shutter sub-assembly.

    2. Control List
      Control Description
      Closing Operation Control When the grille shutter is open and the vehicle conditions are met, the grille shutter closes in order to improve fuel economy (reduce air resistance) and reduce engine warm up time.
      Opening Operation Control When the grille shutter is closed and the vehicle conditions are met, the grille shutter opens to ensure radiator and engine cooling air.
      Ignition Switch Off-linked Opening Operation Control When the ignition switch is turned off and the vehicle is stopped with the grille shutter closed, the grille shutter opens.
      Winter Control Mode During operation in low temperatures when there is a possibility of the grille shutter being stuck due to being frozen, a malfunction judgement is not made even though it is detected that the grille shutter is stuck.
      Retry Operation If a mechanical malfunction is detected during a grille shutter operation, the operation will be attempted again.
