Shutter Grille System Description
For locations of each component on vehicle, refer to Component Location Index
The shutter grille system controls the heat dissipation by controlling the air flow to the engine room during engine warmed-up.
While vehicle running, improving the aerodynamic performance by controlling the opening and closing the shutter grille.
Improving the fuel efficiency by the improvement of the engine warm-up and the aerodynamic performances.
Operation
The powertrain control module (PCM) communicates with the shutter grille through the LIN communication line.
