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 ECM and oil switching solenoid valve. Connector & terminal (B137) No. 25 - (E67) No. 1: (B137) No. 24 - (E67) No. 2:	Is the resistance less than 1 Ω?	Go to step 2.	Repair the open circuit of harness between ECM and oil switching solenoid valve connector. NOTE: In this case, repair the following item: Open circuit of harness between ECM and oil switching solenoid valve connector Poor contact of coupling 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 12 Ω?	Repair the poor contact of ECM and oil switching solenoid valve.	Replace the oil switching solenoid valve. < Ref. to OIL SWITCHING SOLENOID VALVE . >
