CVT MODELS

• When selector lever is P or N, power is supplied to starter relay and starter control relay by transmission

range switch. And BCM and IPDM E/R (CPU) detect selector lever P/N condition by the inputted signal.

• When starter operating condition is satisfied, IPDM E/R turns starter control relay ON by starter control relay

control signal.

• When engine cranking condition is satisfied, BCM turns starter relay ON by starter control relay control sig-

nal.

• Then battery power is supplied to starter motor (“S” terminal) through starter control relay and starter relay.

M/T MODELS

• When the clutch interlock switch is turned ON position (clutch pedal is depressed) power is supplied to

starter relay and starter control relay. And BCM and IPDM E/R (CPU) detect ignition switch position by the
inputted signal.

• When starter operating condition is satisfied, IPDM E/R turns starter control relay ON by starter control relay

control signal.

• When engine cranking condition is satisfied, BCM turns starter relay ON by starter control relay control sig-

nal.

• Then battery power is supplied to starter motor (“S” terminal) through starter control relay and starter relay.

NOTE:
To ensure a complete and thorough diagnosis, the battery, starter motor and alternator test segments must be
done as a set from start to finish.

1.

DIAGNOSIS WITH STARTING/CHARGING SYSTEM TESTER

Perform the starting system test with Starting/Charging System Tester (SST: J-44373). For details and operat-
ing instructions, refer to Technical Service Bulletin.

Test result

CRANKING VOLTAGE NORMAL>>GO TO 2.
CRANKING VOLTAGE LOW>>GO TO 5.
CHARGE BATTERY>>Perform  the  slow  battery charging procedure. (Initial rate of charge is 10A for 12

hours.) Perform battery test again. Refer to Technical Service Bulletin. 

REPLACE BATTERY>>Before replacing battery, clean the battery cable clamps and battery posts. Perform

battery test again. Refer to Technical Service Bulletin. If second test result is “REPLACE BAT-
TERY”, then do so. Perform battery test again to confirm repair.

2.

CRANKING CHECK

Check that the starter motor operates correctly.

Does the engine crank normally?

YES

>> GO TO 3.

NO

>> GO TO 4.

3.

ENGINE START CHECK

Check that the engine starts.

Does the engine start?

YES

>> Starter motor is OK. INSPECTION END

NO

>> Starter motor is OK. Perform further diagnosis of engine mechanical or engine control system.

Refer EM and EC sections. Once resolved, perform battery test again.

4.

STARTER MOTOR ACTIVATION

Check that the starter motor operates.

Does the starter motor turn?

YES

>> Check ring gear and starter motor drive pinion. Once resolved, perform battery test again.

NO

>> GO TO 7.

5.

COMPARISON BETWEEN ENGINE COOLANT AND CRANKING VOLTAGE

Compare the engine coolant temperature and the cranking voltage with the specifications.

Minimum Specification of Cranking Voltage Referencing Coolant Temperature

Is the voltage less than the specified value?

YES

>> GO TO 7.

NO

>> GO TO 6.

6.

STARTER OPERATION

Check the starter operation status.

Does the starter motor turn smoothly?

YES

>> Starter motor is OK. INSPECTION END

NO

>> GO TO 7.

7.

“B” TERMINAL CIRCUIT INSPECTION

Check “B” terminal circuit. Refer to

.

Is “S” connector circuit normal?

YES

>> GO TO 9.

NO
