DIAGNOSIS PROCEDURE


STEP 1. Check oil feeder control valve itself.



  • Oil feeder control valve connector check.
  • Oil feeder control valve check (Refer to ).

Q. Is the check result normal?

Go to Step 2.
Repair or replace the connector, or replace the oil feeder control valve.

STEP 2. Perform voltage measurement at oil feeder control valve connector.



  • Disconnect connector, and measure at harness side.
  • Power supply mode of electric motor switch: ACC
  • Voltage between terminal power supply line and body earth.
OK: System voltage

Q. Is the check result normal?

Go to Step 3.

    Repair or replace the connector, or check and repair harness between engine control relay connector terminal and oil feeder control valve connector terminal power supply line.

    • Check power supply line for open/short circuit.

STEP 3. Perform voltage measurement at engine-ECU connector.



  • Disconnect connector, and measure at harness side.
  • Power supply mode of electric motor switch: ACC
  • Voltage between terminal OCVI and body earth.
OK: System voltage

Q. Is the check result normal?

Go to Step 4.

    Repair or replace the connector, or check and repair harness between oil feeder control valve connector terminal and engine-ECU connector terminal OCVI.

    • Check output line for open/short circuit.

STEP 4. Check harness between engine control relay connector terminal and oil feeder control valve connector terminal.



  • Check power supply line for damage.

Q. Is the check result normal?

Go to Step 5.
Repair or replace the connector, or repair the damaged harness wire.

STEP 5. Check harness between oil feeder control valve connector terminal and engine-ECU connector terminal OCVI.



  • Check output line for damage.

Q. Is the check result normal?

Go to Step 6.
Repair or replace the connector, or repair the damaged harness wire.

STEP 6. M.U.T.-III diagnosis code



  • Reconfirmation of diagnosis code.

Q. Is diagnosis code stored?

Replace the engine-ECU.
Intermittent malfunction (Refer to GROUP 00 - How to Use Troubleshooting/Inspection Service Points - How to Cope with Intermittent Malfunctions ).
