A.A. F System (Active Air Flap)
A.A.F (=Active Air Flap) system installs the openable flaps between radiator and grill. The flap will be closed under the high speed, so it will lower the air resistance in the vehicle and enhance the driving stability. If the internal temperature of engine room is going up, it could overheat the components, so flap will be opened to lower the temperature of engine room. Flap and actuator are directly connected, so it may affect flap's operation if the link part is in damage, disconnection, or mislocation.
