Code P05C1 Honda Description

The shutter grille system open/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 upper or lower temperature is detected as abnormal, the PCM confirms the abnormality and stores a Diagnostic Trouble Code (DTC). The DTC will be set when the internal temperature of the upper or lower actuator is the state of more than 302 °F (150 °C) was continued at least 2.5 seconds or more.
