Diagnostic Procedure

STEP

INSPECTION

RESULTS

ACTION
1
RECORD VEHICLE STATUS AT TIME OF DTC DETECTION TO UTILIZE WITH REPEATABILITY VERIFICATION
Note
•  Recording can be facilitated using the screen capture function of the PC.
•  Record the snapshot data on the repair order.

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
INSPECT ENGINE OIL LEAKAGE
•  Start the engine.
•  Verify that there is no engine oil leakage in the hydraulic circuit.
•  Is there any leakage?
Yes
Repair or replace the malfunctioning part according to the inspection results, then add genuine motor oil.
(See ENGINE OIL REPLACEMENT [SKYACTIV-G 2.5 (WITH CYLINDER DEACTIVATION)].)
No
Go to the next step.
4
INSPECT ENGINE OIL LEVEL
•  Inspect the engine oil level.
•  Is the engine oil level sufficient?
Yes
Go to the next step.
No
Add genuine motor oil.
(See ENGINE OIL REPLACEMENT [SKYACTIV-G 2.5 (WITH CYLINDER DEACTIVATION)].)
5
INSPECT ENGINE OIL TEMPERATURE SENSOR/ENGINE OIL PRESSURE SENSOR CONNECTOR CONDITION
•  Switch the ignition off.
•  Disconnect the engine oil temperature sensor/engine oil pressure sensor connector.
•  Inspect for poor connection (such as damaged/pulled-out pins, corrosion).
•  Is there any malfunction?
Yes
Repair or replace the connector and/or terminals, then go to Step 11.
No
Go to the next step.
6
INSPECT ENGINE OIL SOLENOID VALVE CONNECTOR CONDITION
•  Disconnect the engine oil solenoid valve connector.
•  Inspect for poor connection (such as damaged/pulled-out pins, corrosion).
•  Is there any malfunction?
Yes
Repair or replace the connector and/or terminals, then go to step 11.
No
Go to the next step.
7
INSPECT PCM CONNECTOR CONDITION
•  Disconnect the PCM connector.
•  Inspect for poor connection (such as damaged/pulled-out pins, corrosion).
•  Is there any malfunction?
Yes
Repair or replace the connector and/or terminals, then go to step 11.
No
Go to the next step.
8
INSPECT ENGINE OIL TEMPERATURE SENSOR/ENGINE OIL PRESSURE SENSOR OR ENGINE OIL SOLENOID VALVE CIRCUIT FOR SHORT TO GROUND
•  Verify that the engine oil temperature sensor/engine oil pressure sensor, engine oil solenoid valve and PCM connectors are disconnected.
•  Inspect for continuity between the following terminals (wiring harness-side) and body ground:
―  Engine oil temperature sensor/engine oil pressure sensor terminal A
―  Engine oil temperature sensor/engine oil pressure sensor terminal D
―  Engine oil solenoid valv terminal B
•  Is there continuity?
Yes
Refer to the wiring diagram and verify whether or not there is a common connector between the following terminals:
•  Engine oil temperature sensor/engine oil pressure sensor terminal A—PCM terminal 1D
•  Engine oil temperature sensor/engine oil pressure sensor terminal D—PCM terminal 1AS
•  Engine oil solenoid valv terminal B—PCM terminal 1CK
If there is a common connector:
―  Determine the malfunctioning part by inspecting the common connector and the terminal for corrosion, damage, or pin disconnection, and the common wiring harness for a short to ground.
―  Repair or replace the malfunctioning part.
If there is no common connector:
―  Repair or replace the wiring harness which has a short to ground.
Go to step 11.
No
Go to the next step.
9
INSPECT ENGINE OIL PRESSURE SENSOR
•  Inspect the engine oil pressure sensor.
•  Is there any malfunction?
Yes
Replace the engine oil pressure sensor, then go to the next step.
(See ENGINE OIL TEMPERATURE SENSOR/ENGINE OIL PRESSURE SENSOR REMOVAL/INSTALLATION [SKYACTIV-G 2.5 (WITH CYLINDER DEACTIVATION)].)
No
Go to the next step.
10
INSPECT ENGINE OIL SOLENOID VALVE
•  Inspect the engine oil solenoid valve.
•  Is there any malfunction?
Yes
Replace the engine oil solenoid valve, then go to the next step.
(See ENGINE OIL SOLENOID VALVE REMOVAL/INSTALLATION [SKYACTIV-G 2.5 (WITH CYLINDER DEACTIVATION)].)
No
Replace the oil pump, then go to the next step.
(See OIL PUMP REMOVAL/INSTALLATION [SKYACTIV-G 2.5 (WITH CYLINDER DEACTIVATION)].)
11
VERIFY DTC TROUBLESHOOTING COMPLETED
•  Always reconnect all disconnected connectors.
•  Clear the DTC from the PCM memory using the M-MDS.
•  Start the engine.
•  Increase and keep the engine speed at 2,500 rpm for 5 s.
•  Perform the DTC Reading Procedure.
•  Is the same Pending 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.
12
VERIFY AFTER REPAIR PROCEDURE
•  Perform the “AFTER REPAIR PROCEDURE”.
•  Are any DTCs present?
Yes
Go to the applicable DTC inspection.
