Active Air Shutter Inspection

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.
  1. Connect the M-MDS to the DLC-2.
  2. Switch the ignition ON (engine on).
    NOTE:
    • After several seconds have elapsed, the active air shutter fully open/closed position learning is completed.
  3. 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. (See PID/DATA MONITOR INSPECTION .) (See PID/DATA MONITOR TABLE [PCM (VIN Y)] .) (See PID/DATA MONITOR TABLE [PCM (VIN M)] .)
    • 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. (See DTC INSPECTION .)
  4. Display the PCM PID [AIRSHUT_POS_ACT] and the simulation item [AIRSHUT_POS_COMD] using the M-MDS. (See PID/DATA MONITOR INSPECTION .) (See SIMULATION INSPECTION .) (See PID/DATA MONITOR TABLE [PCM (VIN Y)] .) (See PID/DATA MONITOR TABLE [PCM (VIN M)] .) (See SIMULATION TABLE [PCM (VIN Y)] .) (See SIMULATION TABLE [PCM (VIN M)] .)
  5. 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.
