DTC Advanced Diagnostics: P05C0, P05C1
DTC P05C0:Shutter Grille Actuator (Upper) Temperature Malfunction
DTC P05C1:Shutter Grille Actuator (Lower) Temperature Malfunction

General 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 LIN line. If the upper or lower temperature is detected as abnormal, the PCM confirms the abnormality and stores a DTC.

Possible Cause
NOTE: The causes shown may not be a complete list of all potential problems, and it is possible that there may be other causes.

DTC: P05C0
Upper shutter grille LIN line open
Upper shutter grille LIN line short to ground
Upper shutter grille LIN line short to power

DTC: P05C1

Common
PCM internal circuit failure

Diagnosis Details
Conditions for setting the DTC
When a malfunction is detected, the PGM-FI display comes on and a Pending DTC, a Confirmed DTC, and the freeze data are stored in the PCM memory. The MIL does not come on.

Conditions for clearing the DTC
The PGM-FI display is cleared if the malfunction does not return in three consecutive trips in which the diagnostic runs. The PGM-FI display, the Pending DTC, the Confirmed DTC, and the freeze data can be cleared with the scan tool Clear command.
