Diagnostics for Engine Starting Failure
ENGINE (DIAGNOSTICS)
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?

Repair poor con-
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,
Starter.>
Go to step 5.
5CHECK HARNESS BETWEEN BATTERY
AND IGNITION SWITCH CONNECTOR.
1) Disconnect the connector from ignition
switch.
2) Measure the power supply voltage between
ignition switch connector and chassis ground.
Connector & terminal
(B72) No. 3 (+) — Chassis ground (–):
Is the voltage more than 10 V? Go to step 6.Repair the open
circuit of harness
between ignition
switch and bat-
tery, and check
fuse SBF No. 7
and SBF No. 1.
6CHECK IGNITION SWITCH.
1) Disconnect the connector from ignition
switch.
2) Measure the resistance between ignition
switch terminals after turning the ignition
switch to START position.
Te r m i n a l s
No. 2 — No. 3:
Is the resistance less than 5
Ω?
Go to step 7.Replace the igni-
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.
