Fuel Economy Technology Systems: Active Air Dams
I-CAR · March 14, 2019
Summary
This article explains the function of active air dams as an aerodynamic fuel economy technology and highlights the potential for Diagnostic Trouble Codes (DTCs) if their movement is obstructed. It emphasizes the importance of researching manufacturer-specific repair and diagnostic procedures to ensure the system functions correctly post-collision.
What to do on the job
Research vehicle-specific OEM repair manuals and diagnostic procedures to check for DTCs and ensure proper calibration or operation of the active air dam system before completing repairs.
How to use it
Use this document to justify scanning and diagnostic time for front-end collisions involving active air dams. It helps defend the necessity of clearing DTCs and verifying the physical operation of automated aerodynamic components to prevent post-repair fuel efficiency and emission issues.
