1CHECK OPERATION OF STARTER MOTOR.
Place the inhibitor switch in “P” or “N” range.
Does the starter motor operate
when ignition switch is turned
to START?
Repair the har-
ness and connec-
tor.
NOTE:In this case, repair
the following item:
•Open or
ground short
circuit of har-
ness between
ECM and start-
er motor con-
nector
•Poor contact
in ECM connec-
tor

1CHECK INPUT SIGNAL OF ECM.
1) Turn the ignition switch to OFF.
2) Measure the voltage between ECM and
chassis ground.
Connector & terminal
(B135) No. 5 (+) — Chassis ground (–):
Is the voltage more than 10 V? Repair poor con-
tact in ECM con-
nector.
Go to step 2.

2CHECK HARNESS BETWEEN ECM AND
MAIN FUSE BOX CONNECTOR.
1) Disconnect the connectors from ECM.
2) Measure the resistance of harness
between ECM and chassis ground.
Connector & terminal
(B135) No. 5 — Chassis ground:
Is the resistance less than 10
Ω?
Repair the ground
short circuit of har-
ness between
ECM connector
and battery termi-
nal.
Go to step 3.
3CHECK FUSE No. 13.Is the fuse blown out? Replace the fuse. Repair the har-
ness and connec-
tor.
NOTE:In this case, repair
the following item:
•Open circuit
of harness be-
tween ECM and
battery
•Poor contact
in ECM connec-
tor
•Poor contact
of battery termi-
nal

1CHECK 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. 17 — (E67) No. 1:
(B137) No. 16 — (E67) No. 2:
Is the resistance less than 1
Ω?
Go to step 2.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 be-
tween ECM and
oil flow control
solenoid valve
connector
•Poor contact
of coupling con-
nector
2CHECK 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.
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 flow con-
trol solenoid valve.
Replace the oil
flow control sole-
noid valve. to ME(H6DO)-77,
