Diagnostic Procedure

STEP

INSPECTION

ACTION
1
VERIFY FREEZE FRAME DATA (MODE 2)/SNAPSHOT DATA HAS BEEN RECORDED
•  Has the FREEZE FRAME DATA (Mode 2)/snapshot data been recorded?
Yes
Go to the next step.
No
Record the FREEZE FRAME DATA (Mode 2)/snapshot data on the repair order, then go to the next step.
2
VERIFY RELATED SERVICE INFORMATION AVAILABILITY
•  Verify related Service Information availability.
•  Is any related Service Information available?
Yes
Perform repair or diagnosis according to the available Service Information.
•  If the vehicle is not repaired, go to the next step.
No
Go to the next step.
3

No
Go to the next step.
4
INSPECT EFFECT OF VEHICLE CONDITION FOR MALFUNCTION
•  Verify how the customer drives the vehicle by asking the customer the following:
―  Continue the high engine speed condition with the message related to a diesel particulate filter malfunction in the display. (Type A or type B instrument cluster)
―  Continue the high engine speed condition with the diesel particulate filter indicator light illuminated. (Type C instrument cluster)
―  Vehicle is driven continuously at low engine speed and high load.
•  Are any of the conditions above applicable to the vehicle use conditions?
Yes
Explain to the customer that the vehicle is normal. (malfunction caused by driving at high engine speed with engine oil diluted)
If there is a concern with customer’s driving, provide the customer some pertinent advice (such as gear selection, how to use manual mode).
Go to Step 7.
No
Go to the next step.
5
INSPECT ENGINE OIL LEAKAGE
•  Start the engine.
•  Visually inspect the engine oil runner for engine oil leakage.
•  Is there any leakage?
Yes
Repair or replace the malfunctioning part, add genuine engine oil, then go to Step 7.
No
Go to the next step.
6
INSPECT ENGINE OIL PRESSURE SENSOR
•  Inspect the engine oil pressure sensor.
•  Is there any malfunction?
Yes
Replace the engine oil temperature sensor/engine oil pressure sensor, then go to the next step.
(See ENGINE OIL TEMPERATURE SENSOR/ENGINE OIL PRESSURE SENSOR REMOVAL/INSTALLATION [SKYACTIV-D 2.2].)
No
Go to the next step.
7
VERIFY DTC TROUBLESHOOTING COMPLETED
•  Clear the DTC from the PCM memory using the M-MDS.
•  Start the engine and warm it up completely.
•  Drive the vehicle.
•  Perform the DTC Reading Procedure.
•  Is the same DTC present?
Yes
Repeat the inspection from Step 1.
•  If the malfunction recurs, replace the PCM.
Go to the next step.
No
Go to the next step.
8
VERIFY AFTER REPAIR PROCEDURE
