Abstract:
A method is provided for diagnosing an AGS system fault in a hybrid electric vehicle. That method includes validating shutter movement and inferring shutter position based upon stall current of a shutter drive motor and current drawn by an HEV traction motor. A new and improved active grill shutter system for a hybrid electric vehicle is also disclosed.
