Kia Niro: Cooling System / Active Air Flap (AAF) Description and operation
| Description |
The system receives information from ECU, FATC, TCU, MCU and LDC via CAN communication . With this information, the active air flap (AAF) controls the motor properly then the air flaps adjust air flow from radiator grille.
During high speed driving, it will reduce the air resistance by closing the air flaps. This improves the fuel efficiency and enhance the driving stability. If overheat occurs, the system will open the air flaps to drop the temperature.
During the A/C operation, the system will open the air flaps to maintain the refrigerant pressure. The system will close the air flaps to warm up the engine rapidly during cold start.
