DIAGNOSTIC PROCEDURE

Step	Check	Yes	No
1 CHECK HARNESS BETWEEN ECM AND OIL CONTROL SOLENOID RH CONNECTOR. Turn the ignition switch to OFF. Disconnect the connectors from ECM and oil control solenoid RH. Measure the resistance of harness between ECM and oil control solenoid RH connector. Connector & terminal (B134) No. 34 - (E38) No. 1: (B134) No. 27 - (E38) No. 2:	Is the resistance less than 1 Ω?	Go to step 2 .	Repair the harness and connector. NOTE: In this case, repair the following item: Open circuit in harness between ECM and oil control solenoid RH connector Poor contact of coupling connector
2 CHECK HARNESS BETWEEN ECM AND OIL CONTROL SOLENOID RH CONNECTOR. Measure the resistance between ECM and chassis ground. Connector & terminal (B134) No. 34 - Chassis ground: (B134) No. 27 - Chassis ground:	Is the resistance 1 MΩ or more?	Go to step 3 .	Repair the short circuit to ground in harness between ECM and oil control solenoid RH 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 RH connector.	Replace the oil control solenoid RH. < Refer to OIL CONTROL SOLENOID . >
