CHECK HARNESS BETWEEN ECM AS WELL AS MAIN RELAY AND INTAKE OIL FLOW CONTROL SOLENOID VALVE RH CONNECTOR.

Measure the resistance of harness between ECM and main relay connector and intake oil flow control solenoid valve RH connector.

Connector & terminal

(B220) No. 38 — (E38) No. 1:

(B134) No. 33 — (E38) No. 2:

QUESTION

Is the resistance less than 1 Ω?

Yes No

Repair the harness and connector.

NOTE:

In this case, repair the following item:

• Open circuit in harness between ECM and intake oil flow control solenoid valve RH connector

• Open circuit in harness between main relay and intake oil flow control solenoid valve RH connector

• Poor contact of coupling connector
