WIRING DIAGRAM:

STEPCHECKYESNO

1.CHECK HARNESS BETWEEN ECM AND OIL FLOW CONTROL SOLENOID VALVE.

1) Turn the ignition switch to OFF.

2) Disconnect the connectors from ECM and oil flow control solenoid valve.

3) Measure the resistance between ECM and oil flow control solenoid valve.

Connector & terminal

(B137) No. 15 — (E37) No. 1:

(B137) No. 14 — (E37) No. 2:

Is the resistance less than 1 Ω?

Repair the open circuit of harness between ECM and oil flow control solenoid valve connector.

NOTE:

In this case, repair the following item:

• Open circuit of harness between ECM and oil flow control solenoid valve connector

• Poor contact of coupling connector

2.CHECK HARNESS BETWEEN ECM AND OIL FLOW CONTROL SOLENOID VALVE.

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

Connector & terminal

(E37) No. 1 — Engine ground:

(E37) No. 2 — Engine ground:

Is the resistance 1 MΩ or more?

Repair the ground short circuit of harness between ECM and oil flow control solenoid valve connector.

3.CHECK OIL FLOW CONTROL SOLENOID VALVE.

1) Remove the oil flow control solenoid valve connector.

2) Measure the resistance between oil flow control solenoid valve terminals.

Terminals

No. 1 — No. 2:

Is the resistance between 6 — 12 Ω?

Repair the poor contact of ECM and oil flow control solenoid valve.

Replace the oil flow control solenoid valve.
