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
AWBIA1200GB
STR-22
< BASIC INSPECTION >
DIAGNOSIS AND REPAIR WORKFLOW
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 Instruction.
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 instruction.
REPLACE BATTERY>>Before replacing battery, clean the battery cable clamps and battery posts. Perform
battery test again. Refer to diagnostic station instruction instruction. 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.
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
>> Inspection End.
NO
>> GO TO 7.
7.
“B” TERMINAL CIRCUIT INSPECTION
Check “B” terminal circuit. Refer to
.
Is “B” terminal circuit normal?
YES
>> GO TO 8.
NO
>> Repair as needed.
8.
“S” CONNECTOR CIRCUIT INSPECTION
Check “S” connector circuit. Refer to
.
