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
VERIFY RELATED PENDING CODE AND/OR DTC
•  Switch the ignition off, then ON (engine off).
•  Perform the Pending Trouble Code Access Procedure and DTC Reading Procedure.
•  Are any other PENDING CODEs and/or DTCs present?
Yes
Go to the applicable PENDING CODE or DTC inspection.
(See DTC TABLE [SKYACTIV-D 2.2].)
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 "Soot Accumulation in DPF too high" displayed in the TFT LCD. (with TFT LCD)
―  Continue high engine speed condition with the DPF indicator light illuminated. (without TFT LCD)
―  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
―  Malfunction caused by continuously driving vehicle at low engine speed and high load
If there is a concern with customer’s driving, provide the customer some pertinent advice (such as gear selection, how to use manual mode).
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
Replace the PCM, then go to the next step.
(See PCM REMOVAL/INSTALLATION [SKYACTIV-D 2.2].)
8
VERIFY AFTER REPAIR PROCEDURE
•  Perform the “AFTER REPAIR PROCEDURE”.
•  Are any DTCs present?
Yes
Go to the applicable DTC inspection.
(See DTC TABLE [SKYACTIV-D 2.2].)
No
DTC troubleshooting completed.
