Code P05AE 2021 Honda CR-V 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 depend on the driving conditions to the shutter grille via the LIN line. If the upper or lower actuator is detected as abnormal, the PCM confirms the abnormality and stores a Diagnostic Trouble Code (DTC). The DTC will be set when the upper or lower actuator does not reach the fully open position or the fully closed position by initial learning in the fully open position or fully closed position + 12% or more of the opening with respect to the position or the upper or lower actuator does not reach the fully open or fully closed position by rotated 125° or more.
