Step Check Yes No
1CHECK HARNESS BETWEEN ECM AND OIL
SWITCHING SOLENOID VALVE.
1) Turn the ignition switch to OFF.
2) Disconnect the connector from ECM and oil
switching solenoid valve.
3) Measure the resistance between ECM and
oil switching solenoid valve.
Connector & terminal
(B137) No. 25 — (E69) No. 1:
(B137) No. 24 — (E69) No. 2:
Is the resistance less than 1
Ω?
Go to step 2.Repair the open
circuit of harness
between ECM and
oil switching sole-
noid valve connec-
tor.
NOTE:In this case, repair
the following item:
•Open circuit
of harness be-
tween ECM and
oil switching so-
lenoid valve
connector
•Poor contact
of coupling con-
nector
2CHECK OIL SWITCHING SOLENOID VALVE.
1) Remove the oil switching solenoid valve
connector.
2) Measure the resistance between oil switch-
ing solenoid valve terminals.
Te r m i n a l s
No. 1 — No. 2:
Is the resistance between 6 —
12 Ω?
Repair the poor
contact of ECM
and oil switching
solenoid valve.
Replace the oil
switching solenoid
valve.
