Step Check Yes No
1CHECK BATTERY.
Check the battery voltage.
Is the voltage more than 12 V? Go to step 2.Charge or replace
the battery.
2CHECK OPERATION OF STARTER MOTOR.Does the starter motor oper-
ate?
Go to step 3.Go to step 4.
3CHECK DTC.Is DTC displayed? EN(H6DO)(diag)-34, OPERA-
TION, Read Diagnostic Trouble
Code (DTC).>
Check the appro-
priate DTC using
the List of Diag-
nostic Trouble
Code (DTC). to

tact in ECM con-
nector.
4CHECK INPUT SIGNAL FOR STARTER MO-
TOR.
1) Turn the ignition switch to OFF.
2) Disconnect the connector from starter
motor.
3) Turn the ignition switch to START.
4) Measure the power supply voltage between
starter motor connector terminal and engine
ground.
Connector & terminal
(B14) No. 1 (+) — Engine ground (–):
NOTE:Place the select lever in “P” or “N” range.
Is the voltage more than 10 V? Check the starter
motor. SC(H6DO)-6,

circuit of harness
between ignition
switch and bat-
tery, and check
fuse SBF No. 7
and SBF No. 1.

tion switch.
7CHECK INPUT VOLTAGE OF STARTER RE-
LAY.
1) Turn the ignition switch to OFF.
2) Disconnect the connector from starter relay.
3) Connect the connector to ignition switch.
4) Measure the input voltage between starter
relay connector and chassis ground after turn-
ing the ignition switch to START position.
Connector & terminal
(B225) No. 13 (+) — Chassis ground (–):
(B225) No. 15 (+) — Chassis ground (–):
Is the voltage more than 10 V? Go to step 8.Repair the open
circuit of harness
between starter
relay and ignition
switch.

8CHECK STARTER RELAY.
1) Connect the battery to starter relay termi-
nals No. 15 and No. 16.
2) Measure the resistance between starter
relay terminals.
Te r m i n a l s
No. 13 — No. 14:
Is the resistance less than 1
Ω?
Go to step 9.Replace the
starter relay.
9CHECK INPUT VOLTAGE FROM ECM.
1) Turn the ignition switch to OFF.
2) Connect the connector to starter relay.
3) Disconnect the connectors from ECM.
4) Measure the voltage between ECM and
chassis ground.
Connector & terminal
(B136) No. 32 (+) — Chassis ground (–):
(B136) No. 20 (+) — Chassis ground (–):
Is the voltage more than 10 V? Replace the ECM.
