DIAGNOSIS AND REPAIR WORKFLOW

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 (J-44373). For details and operating

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 properly.
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

>> Perform further diagnosis of engine mechanical or engine control system. Refer to 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 verify the cranking voltage is within specification.

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.
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

STR-34, "Diagnosis Procedure"

.

Is “B” terminal circuit normal?

Engine coolant temperature [

°C (°F)]

Voltage [V]

−30 to −20 (−22 to −4)

8.6

−19 to −10 (−2 to 14)

9.1

−9 to 0 (16 to 32)

9.5

More than 1 (More than 34)

“S” CONNECTOR CIRCUIT INSPECTION

Check “S” connector circuit. Refer to

STR-35, "Diagnosis Procedure"

.

Is “S” connector circuit normal?

YES

>> GO TO 9

NO

>> Repair as needed.

9.

ENGINE ROTATION STATUS

Check that the engine can be rotated by hand.
Does the engine turn freely by hand?

YES

>> Replace starter motor.

NO

>> Perform further diagnosis of engine mechanical or powertrain mechanism. Refer to EM, TM or CL

sections. Once resolved, perform battery test again. Refer to Technical Service Bulletin.
