DTC CONFIRMATION PROCEDURE
1.PERFORM COMPONENT FUNCTION CHECK
Perform component function check. Refer to EC, "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 >> Go to EC, "Diagnosis Procedure".
1.PRECONDITIONING
TESTING CONDITION:
>> GO TO 2.
2.PERFORM COMPONENT FUNCTION CHECK
With CONSULT
"BAT CUR SEN" should be above 2,300 mV at least once.
Without CONSULT
Is the inspection result normal?
YES >> INSPECTION END
NO >> Go to EC, "Diagnosis Procedure"
1.CHECK GROUND CONNECTION
Is the inspection result normal?
YES >> GO TO 2.
NO >> Repair or replace ground connection.
2.CHECK BATTERY CURRENT SENSOR POWER SUPPLY
Is the inspection result normal?
YES >> GO TO 4.
NO >> GO TO 3.
3.CHECK BATTERY CURRENT SENSOR POWER SUPPLY CIRCUIT
Is the inspection result normal?
YES >> Check intermittent incident. Refer to GI, "Intermittent Incident".
NO >> Repair or replace error-detected parts.
4.CHECK BATTERY CURRENT SENSOR GROUND CIRCUIT FOR OPEN AND SHORT
Is the inspection result normal?
YES >> GO TO 5.
NO >> Repair or replace error-detected parts.
5.CHECK BATTERY CURRENT SENSOR INPUT SIGNAL CIRCUIT FOR OPEN AND SHORT
Is the inspection result normal?
YES >> GO TO 6.
NO >> Repair or replace error-detected parts.
6.CHECK BATTERY CURRENT SENSOR
Check battery current sensor. Refer to EC, "Component Inspection".
Is the inspection result normal?
YES >> Check intermittent incident. Refer to GI, "Intermittent Incident".
NO >> Replace battery negative cable assembly.
1.CHECK BATTERY CURRENT SENSOR
Is the inspection result normal?
YES >> INSPECTION END
NO >> Replace battery negative cable assembly.
