Function Explanation (DTC Detection Outline)

Repeatability Verification Procedure

PID Item/Simulation Item Used In Diagnosis

Function Inspection Using M-MDS

Step	Inspection	Results	Action
1	PURPOSE: VERIFY RELATED REPAIR INFORMATION OR SERVICE INFORMATION AVAILABILITY •  Verify related Service Bulletins, on-line repair information, or Service Information availability. •  Is any related Information available?	Yes	Perform repair or diagnosis according to the available information. •  If the vehicle is not repaired, go to the next step.
		No	Go to the next step.
2	INSPECT FOR OTHER RELATED DTCs •  Perform the DTC inspection for the PCM. (See DTC INSPECTION.) •  Are any of the following DTCs displayed? ―  U0284:00	Yes	Repair the malfunctioning location according to the applicable DTC troubleshooting. (See DTC U0284:00 [PCM (SKYACTIV-D)].)
		No	Go to the next step.
3	PURPOSE: RECORD VEHICLE STATUS WHEN DTC WAS DETECTED TO UTILIZE WITH REPEATABILITY VERIFICATION •  Record the freeze frame data/snapshot data. Note •  Recording can be facilitated using the screen capture function of the PC.	—	Go to Troubleshooting Diagnostic Procedure to perform the procedure from Step 1.

Troubleshooting Diagnostic Procedure

―  Perform inspection of each separate part.

―  Verify that the primary malfunction is resolved and there are no other malfunctions.

Step	Inspection	Results	Action
1	PURPOSE: INSPECT ACTIVE AIR SHUTTER FOR MALFUNCTION •  Inspect the applicable part. (See ACTIVE AIR SHUTTER INSPECTION.) •  Is the part normal?	Yes	Go to the next step.
		No	Repair or replace the malfunctioning location and perform the repair completion verification. (See ACTIVE AIR SHUTTER REMOVAL/INSTALLATION.)
Repair completion verification 1	PURPOSE: VERIFY THAT VEHICLE IS REPAIRED Caution •  Connect the negative battery terminal before connecting the current sensor connector. If the current sensor connector is connected first, the PCM may mistakenly recognize a signal from the current sensor and learn the battery condition incorrectly. •  Install/connect the part removed/disconnected during the troubleshooting procedure. •  Clear the DTC recorded in the memory. (See CLEARING DTC.) •  Replicate the vehicle conditions at the time the DTC was detected using the following procedure. ―  Implement the repeatability verification procedure. (See Repeatability Verification Procedure.) •  Perform the DTC inspection for the PCM. (See DTC INSPECTION.) •  Is the same Pending DTC present?	Yes	Refer to the controller area network (CAN) malfunction diagnosis flow to inspect for a CAN communication error. (See CONTROLLER AREA NETWORK (CAN) MALFUNCTION DIAGNOSIS FLOW [(E)].) If the CAN communication is normal, perform the diagnosis from Step 1. •  If the malfunction recurs, replace the PCM, then go to the next step. (See PCM REMOVAL/INSTALLATION [SKYACTIV-D 1.8].)
		No	Go to the next step.
Repair completion verification 2	PURPOSE: VERIFY IF OTHER DTCs DISPLAYED •  Perform the DTC inspection. (See DTC INSPECTION.) •  Are any other DTCs displayed?	Yes	Repair the malfunctioning location according to the applicable DTC troubleshooting.
		No	DTC troubleshooting completed.
