C062E Active Air Dam Supply Voltage Circuit Low

Check engine lightUsually off
EmissionsNot relevant
Drive cycleNot required
Limp modeNo

The active air dam actuators run from the vehicle battery while the PCM or body module commands them over LIN or CAN, as Ford's patent lays out. C062E reports that the supply reaching the actuator or its module is too low to move the panel safely. Small LIN motor drivers made for flaps and grille shutters watch this themselves: Melexis' MLX81350 has an undervoltage threshold selectable between about 4 and 9 V. Stellantis shows a related field case on the Ram 1500: lost contact with the air dam plus system-voltage-low codes in several modules, traced to loose grounds G921/G933/G904 and fluid wicking into inline connector XY110A. No maker publishes C062E. The panel stops where it is until supply recovers.

Likely causes

Loose or corroded ground point in the front harness
Water or washer fluid wicking into an inline connector
Weak battery or low charging voltage
High resistance in fuse or feed wire to the actuator

Symptoms

  • Air dam no longer moves and stays in its last position
  • Air dam fault message in the cluster
  • Low-voltage codes in other modules at the same time
