Work Flow (With GR8-1200 NI)

STARTING SYSTEM DIAGNOSIS WITH GR8-1200 NI

To test the starting system, use the following special service tool:

• GR8-1200 NI Multitasking battery and electrical diagnostic station

NOTE: Refer to the diagnostic station Instruction Manual for proper starting system diagnosis procedures.

OVERALL SEQUENCE

DETAILED FLOW

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

1.DIAGNOSIS WITH MULTITASKING BATTERY AND ELECTRICAL DIAGNOSTIC STATION GR8-1200 NI

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 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 >> 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 specifications. 

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 >> Inspection End.

NO >> GO TO 7.

7."B" TERMINAL CIRCUIT INSPECTION

Check "B" terminal circuit. Refer to STR, "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 STR, "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. Once resolved, perform battery test again using Multitasking battery and electrical diagnostic station GR8-1200 NI.

Refer to the diagnostic station Instruction Manual for proper testing procedures.

NO >> Check charge condition, corrosion and connection condition of the battery.

5.CHECK STARTER MOTOR ACTIVATION

Check that the starter motor runs at cranking.

Does starter motor turn?

YES >> Replace starter motor. Refer to STR, "Removal and Installation".

NO >> GO TO 6.

6.CHECK POWER SUPPLY CIRCUIT

Check the following conditions:

• Fuse and fusible link
• Charge condition, corrosion and connection of the battery.

Are these inspection results normal?

YES >> GO TO 7.

NO >> Repair as needed.

7.CHECK STARTING SYSTEM WIRING

Check the following:

• "B" terminal circuit. Refer to STR, "Diagnosis Procedure".
• "S" terminal circuit. Refer to STR, "Diagnosis Procedure".

Are the inspection results normal?

YES >> Replace starter motor. Refer to STR, "Removal and Installation".

NO >> Repair as needed.
