C062FActive Air Dam Supply Voltage Circuit High
- Generic OBD-II code · Chassis
- How the car detects it
- C062F is the overvoltage side: the supply at the air dam actuator or its module lies above the permitted window. Ford's patent powers the screw-jack actuators from the vehicle battery, so a regulator fault in the charging system, jump-starting with a higher voltage or a load dump spike can push the feed too high. Driver electronics guard against this: Melexis' MLX81350 LIN motor driver, offered for flaps and grille shutters, trips at about 22, 24 or 40 V depending on setting, and TI's DRV8873-Q1 is rated for at most 38 V. A GM air dam patent checks position, current and back-EMF but takes the supply as given, so the supply code stands apart. No maker publishes C062F. The actuator usually stops until the voltage drops.
