Function Inspection Using M-MDS

Step	Inspection	Results	Action
1	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 the next step.
2	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.
3	PURPOSE: DETERMINE IF MALFUNCTION IS CAUSED BY ACTUATOR POSITION SENSOR (TURBOCHARGER WITH VARIABLE TURBINE GEOMETRY) MALFUNCTION •  Inspect the actuator position sensor (turbocharger with variable turbine geometry). (See ACTUATOR POSITION SENSOR (TURBOCHARGER WITH VARIABLE TURBINE GEOMETRY) INSPECTION [SKYACTIV-D 1.8].) •  Is the actuator position sensor (turbocharger with variable turbine geometry) normal?	Yes	Go to Troubleshooting Diagnostic Procedure to perform the procedure from step 1.
		No	Inspect the related wiring harnesses and connectors. •  Repair or replace the malfunctioning location. Go to the troubleshooting procedure to perform the procedure from repair completion verification 1.

Troubleshooting Diagnostic Procedure

―  Verify that there is no problem with engagement of each separate part.

―  Perform an inspection of the connectors and wiring harnesses between the actuator position sensor (turbocharger with variable turbine geometry) terminal and PCM.

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

Step	Inspection	Results	Action
1	PURPOSE: VERIFY IF CONNECTOR DAMAGE OF EACH PART AFFECTS DIAGNOSTIC RESULTS •  Switch the ignition OFF. •  Disconnect the connectors of the following parts: ―  Actuator position sensor (turbocharger with variable turbine geometry) ―  PCM •  Inspect the connector engagement and connection condition, and inspect the terminals for damage, deformation, corrosion, or disconnection. •  Is the connector normal?	Yes	Go to the next step.
		No	Repair or replace the connector, then go to repair completion verification.
2	PURPOSE: INSPECT ACTUATOR POSITION SENSOR (TURBOCHARGER WITH VARIABLE TURBINE GEOMETRY) POWER SUPPLY CIRCUIT AND SIGNAL CIRCUIT FOR SHORT TO GROUND •  Inspect the applicable circuit for a short to ground. (See CIRCUIT INSPECTION.) •  Is the circuit normal?	Yes	Go to the next step.
		No	Repair or replace the malfunctioning location and perform the repair completion verification.
3	PURPOSE: INSPECT ACTUATOR POSITION SENSOR (TURBOCHARGER WITH VARIABLE TURBINE GEOMETRY) GROUND CIRCUIT AND SIGNAL CIRCUIT FOR SHORT CIRCUIT •  Inspect the applicable circuits for a short circuit. (See CIRCUIT INSPECTION.) •  Is the circuit normal?	Yes	Go to repair completion verification.
		No	Repair or replace the malfunctioning location and perform the repair completion verification.
4	PURPOSE: INSPECT ACTUATOR POSITION SENSOR (TURBOCHARGER WITH VARIABLE TURBINE GEOMETRY) SIGNAL CIRCUIT FOR OPEN CIRCUIT •  Inspect the applicable circuit for open circuit. (See CIRCUIT INSPECTION.) •  Is the circuit normal?	Yes	Go to the next step.
		No	Repair or replace the malfunctioning location and perform the repair completion verification.
5	PURPOSE: INSPECT ACTUATOR POSITION SENSOR (TURBOCHARGER WITH VARIABLE TURBINE GEOMETRY) FOR MALFUNCTION •  Inspect the applicable part. (See ACTUATOR POSITION SENSOR (TURBOCHARGER WITH VARIABLE TURBINE GEOMETRY) INSPECTION [SKYACTIV-D 1.8].) •  Is the part normal?	Yes	Go to the next step.
		No	Repair or replace the malfunctioning location and perform the repair completion verification. (See TURBOCHARGER WITH VARIABLE TURBINE GEOMETRY REMOVAL/INSTALLATION [SKYACTIV-D 1.8].)
Repair completion verification 1	PURPOSE: VERIFY THAT VEHICLE IS REPAIRED •  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.
