DIAGNOSTIC PROCEDURE

Step	Check	Yes	No
1 CHECK HARNESS BETWEEN ECM AND OIL CONTROL SOLENOID LH CONNECTOR. Turn the ignition switch to OFF. Disconnect the connectors from ECM and oil control solenoid LH. Measure the voltage between ECM and chassis ground. Connector & terminal (B134) No. 17 (+) - Chassis ground (-): (B134) No. 16 (+) - Chassis ground (-):	Is the voltage less than 1 V?	Go to step 2 .	Repair the short circuit to power supply in harness between ECM and oil control solenoid LH connector.
2 CHECK HARNESS BETWEEN ECM AND OIL CONTROL SOLENOID LH CONNECTOR. Measure the resistance of harness between ECM and oil control solenoid LH connector. Connector & terminal (B134) No. 17 - (E37) No. 1: (B134) No. 16 - (E37) No. 2:	Is the resistance less than 1 Ω?	Go to step 3 .	Repair the harness and connector. NOTE: In this case, repair the following item: Open circuit in harness between ECM and oil control solenoid LH connector Poor contact of coupling connector
3 CHECK OIL CONTROL SOLENOID. Measure the resistance between oil control solenoid terminals. Terminals No. 1 - No. 2:	Is the resistance 6 - 12 Ω?	Repair the poor contact of ECM and oil control solenoid LH connector.	Replace the oil control solenoid LH. < Refer to OIL CONTROL SOLENOID . >
