Repair Procedure Summary
Hyundai Technical Service Bulletin 23-01-075H outlines a detailed procedure for replacing the Active Air Flap (AAF) actuator. The repair begins with disconnecting the negative battery terminal and removing the front trunk assembly. Technicians then partially remove the fender garnish and the front bumper assembly to gain access.
Key steps include disconnecting the front bumper main connector and the AAF control unit connector. The faulty AAF actuator is then removed by loosening its mounting screws. A new AAF actuator, specific to either the left-hand (LH) or right-hand (RH) side, is installed. Proper alignment of a star-shaped protrusion into the matching hole in the AAF actuator is crucial during installation.
Finally, all components are reinstalled in the reverse order of disassembly, and the negative battery terminal is reconnected. The AAF system's normal operation is verified after the ignition is turned ON. The procedure concludes with checking for and clearing any stored failure codes, specifically confirming that the DTC U028400 does not return.
