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 MULTITASKING BATTERY AND ELECTRICAL DIAGNOSTIC STATION GR8-1200 NI

JMBIA4453GB

STR-4

< BASIC INSPECTION >

DIAGNOSIS AND REPAIR WORK FLOW

Perform the starting system test with Multitasking battery and electrical diagnostic station GR8-1200 NI. For
details and operating instructions, refer to diagnostic station Instruction Manual.
Test result

CRANKING NORMAL>>GO TO 2.
LOW VOLTAGE>>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 diagnostic station instruction manual. 

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

battery test again. Refer to diagnostic station instruction manual. If second test result is
“REPLACE BATTERY”, 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

>> Perform further diagnosis of engine mechanical or engine control system. Refer EM and EC sec-

tions. 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 

STR-9, "Diagnosis Procedure"

.

Is “B” terminal circuit normal?

YES

>> GO TO 8.

NO

>> Repair as needed.

8.

“S” CONNECTOR CIRCUIT INSPECTION

Check “S” connector circuit. Refer to

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

YES

>> Replace starter motor. Refer to 

STR-20, "Removal and Installation"

.

NO

>> Perform further diagnosis of engine mechanical or powertrain mechanism. Once resolved, per-

form battery test again using Multitasking battery and electrical diagnostic station GR8-1200 NI.
