DTC P05C0: Shutter Grille Actuator Temperature Malfunction

General Description

Courtesy of HONDA, U.S.A., INC.

The shutter grille system opens/closes the shutter depending on the driving conditions. The system improves fuel efficiency by reducing the wind drag. The shutter is controlled by the shutter grille which integrates the actuator. The powertrain control module (PCM) sends open/close requests which depends on the driving conditions to the shutter grille via the local interconnect network (LIN) line. If the temperature is detected as abnormal, the PCM confirms the abnormality and stores a DTC.
