DIAGNOSIS PROCEDURE

Step	Check	Yes	No
1 CHECK HARNESS BETWEEN ECM AND OIL SWITCHING SOLENOID VALVE. Turn the ignition switch to OFF. Disconnect the connector from ECM and oil switching solenoid valve. Measure the resistance between oil switching solenoid valve and engine ground. Connector & terminal (E67) No. 1 - Engine ground: (E67) No. 2 - Engine ground:	Is the resistance more than 1 MΩ?	Go to step 2.	Repair the short circuit between ECM and oil switching solenoid valve connector.
2 CHECK OIL SWITCHING SOLENOID VALVE. Remove the oil switching solenoid valve connector. Measure the resistance between oil switching solenoid valve terminals. Terminals No. 1 - No. 2:	Is the resistance between 6 and 12Ω?	Repair the poor contact of ECM and oil switching solenoid valve.	Replace the oil switching solenoid valve. < Ref. to OIL SWITCHING SOLENOID VALVE . >
