Diagnostic Procedure with Diagnostic Trouble Code (DTC)
Step
Check
Yes
No
1
CHECK 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 oil switch-
ing solenoid valve and engine ground.
Connector & terminal
(E69) No. 1 — Engine ground:
(E69) No. 2 — Engine ground:
Is the resistance more than 1
M
Ω?
Repair the short
circuit between
ECM and oil
switching solenoid
valve connector.
2
CHECK OIL SWITCHING SOLENOID VALVE.
1) Remove the oil switching solenoid valve
connector.
2) Measure the resistance between oil switch-
ing solenoid valve terminals.
Terminal
No. 1 — No. 2:
Is the resistance 6 — 12
Ω
Repair the poor
contact in ECM
and oil switching
solenoid valve.
Replace the oil
switching solenoid
valve. <Ref. to
ME(H6DO)-80, Oil
Switching Sole-
noid Valve.>

1
CHECK 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
(B135) No. 25 — (E70) No. 1:
(B135) No. 24 — (E70) No. 2:
Is the resistance less than 1
Ω?
Repair the open
circuit of harness
between ECM and
oil switching sole-
noid valve connec-
tor.
NOTE:
In this case, repair
the following:
• Open circuit of
harness between
ECM and oil
switching solenoid
valve connector
• Poor contact in
coupling connector
2
CHECK OIL SWITCHING SOLENOID VALVE.
1) Remove the oil switching solenoid valve
connector.
2) Measure the resistance between oil switch-
ing solenoid valve terminals.
Terminal
No. 1 — No. 2:
Is the resistance 6 — 12

Repair the poor
contact in ECM
and oil switching
solenoid valve.
Replace the oil
switching solenoid
valve. <Ref. to
