Active Air Shutter Inspection
WARNING: This page is about a different car, the 2024 Mazda CX-30. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
- The integrity of the active air shutter cannot be determined from a single part. When inspecting the active air shutter, perform the following procedure.
- Connect the M-MDS to the DLC-2.
- Switch the ignition ON (engine on).NOTE:
- After several seconds have elapsed, the active air shutter fully open/closed position learning is completed.
- Using the M-MDS, display the PCM PID [AIRSHUT_CAL_STAT] and verify that the active air shutter fully open/close position learning is completed.
(Refer to PID/DATA MONITOR TABLE [PCM (VIN M)]
.) in the troubleshooting service information
)
- If the active air shutter fully open/close position learning is not completed, perform a PCM DTC inspection and verify if a DTC is detected. (Refer to DTC INSPECTION .) in the troubleshooting service information )
- Display the PCM PID [AIRSHUT_POS_ACT] and the simulation item [AIRSHUT_POS_COMD] using the M-MDS. (Refer to PID/DATA MONITOR TABLE [PCM (VIN M)] .) in the troubleshooting service information ) (Refer to SIMULATION TABLE [PCM (VIN M)] .) in the troubleshooting service information )
- Verify that the PID [AIRSHUT_POS_ACT] value changes according to the simulation item [AIRSHUT_POS_COMD] value when the simulation item [AIRSHUT_POS_COMD] is driven from 0 degrees to the maximum value.
- If it cannot be verified, replace the active air shutter. (See ACTIVE AIR SHUTTER REMOVAL/INSTALLATION .)
