DTC CONFIRMATION PROCEDURE
1.PERFORM COMPONENT FUNCTION CHECK
Perform component function check. Refer to EC-383, "Component Function Check".
NOTE:
Use component function check to check the overall function of the battery current sensor circuit. During this check, a 1st trip DTC might not be confirmed.
Is the inspection result normal? YES >> INSPECTION END
NO >> Proceed to EC-384, "Diagnosis Procedure".
Component Function Check
1.PRECONDITIONING
TESTING CONDITION:
Before performing the following procedure, confirm that battery voltage is more than 12.8 V at idle.
Before performing the following procedure, confirm that all load switches and A/C switch are turned OFF.
>> GO TO 2.
2.PERFORM COMPONENT FUNCTION CHECK
With CONSULT
“BAT CUR SEN” : above 2,300 mv at least once
Without
CONSULT
Is the inspection result normal? YES >> INSPECTION END
NO >> Proceed to EC-384, "Diagnosis Procedure".
Diagnosis Procedure
1.CHECK BATTERY CURRENT SENSOR POWER SUPPLY
Is the inspection result normal? YES >> GO TO 3.
NO >> GO TO 2.
2.CHECK SENSOR POWER SUPPLY 2 CIRCUIT
Check sensor power supply 2 circuit. Refer to EC-444, "Diagnosis Procedure".
Is the inspection result normal? YES >> Perform the trouble diagnosis for power supply circuit.
NO >> Repair or replace error-detected parts.
3.CHECK BATTERY CURRENT SENSOR GROUND CIRCUIT
Is the inspection result normal? YES >> GO TO 4.
NO >> Repair or replace error-detected parts.
4.CHECK BATTERY CURRENT SENSOR INPUT SIGNAL CIRCUIT
Is the inspection result normal? YES >> GO TO 5.
NO >> Repair or replace error-detected parts
5.CHECK BATTERY CURRENT SENSOR
Check the battery current sensor. Refer to EC-385, "Component Inspection (Battery Current Sensor)".
Is the inspection result normal? YES >> Check intermittent incident. Refer to GI-39, "Intermittent Incident".
NO >> Replace battery current sensor. Refer to PG-53, "Removal and Installation".
Component Inspection (Battery Current Sensor)
1.CHECK BATTERY CURRENT SENSOR
Before measuring the terminal voltage, confirm that the battery is fully charged. Refer to PG-4, "How to Handle Battery".
Is the inspection result normal?
YES >> INSPECTION END
NO >> Replace battery current sensor. Refer to PG-53, "Removal and Installation".
