Measure the resistance of harness between ECM and oil flow control solenoid valve connector.

Connector & terminal

(B137) No. 17 — (E38) No. 1:

(B137) No. 16 — (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 of harness between ECM and oil flow control solenoid valve connector

• Poor contact in coupling connector
