DTC DETECTION LOGIC
DTC CONFIRMATION PROCEDURE
1.PERFORM COMPONENT FUNCTION CHECK
Perform component function check. Refer to EC-709, "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-710, "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-III
1. Start engine and let it idle.
2. Select “BAT CUR SEN” in “DATA MONITOR” mode with CONSULT-III.
3. Check “BAT CUR SEN” indication for 10 seconds.
“BAT CUR SEN” should be above 2,300 mV at least once.
Without CONSULT-III
1. Start engine and let it idle.
2. Check the voltage between ECM harness connector and ground.
Is the inspection result normal? YES >> INSPECTION END
NO >> Go to EC-710, "Diagnosis Procedure".
Diagnosis Procedure
1.CHECK BATTERY CURRENT SENSOR POWER SUPPLY
1. Turn ignition switch OFF.
2. Disconnect battery current sensor harness connector.
3. Turn ignition switch ON.
4. Check the voltage between battery current sensor harness connector and ground.
Is the inspection result normal? YES >> GO TO 3.
NO >> GO TO 2.
2.CHECK SENSOR POWER SUPPLY CIRCUIT
1. Turn ignition switch OFF.
2. Disconnect ECM harness connector.
3. Check harness connector for short to power and short to ground, between the following terminals.
*1: LHD models or RHD models with CVT *2: RHD models with M/T
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
1. Turn ignition switch OFF.
2. Disconnect ECM harness connector.
3. Check the continuity between battery current sensor harness connector and ECM harness connector.
4. Also check harness for short to power.
Is the inspection result normal? YES >> GO TO 4.
NO >> Repair or replace error-detected parts.
4.CHECK BATTERY CURRENT SENSOR INPUT SIGNAL CIRCUIT
1. Check the continuity between battery current sensor harness connector and ECM harness connector
2. Also check harness for short to ground and to power.
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-702, "Component Inspection".
Is the inspection result normal? YES >> Check intermittent incident. Refer to GI-42, "Intermittent Incident".
NO >> Replace battery negative cable assembly. Refer to PG-125, "Exploded View".
Component Inspection
1.CHECK BATTERY CURRENT SENSOR
1. Turn ignition switch OFF.
2. Reconnect harness connectors disconnected.
3. Disconnect battery negative cable.
4. Install jumper cable between battery negative terminal and body ground.
5. Turn ignition switch ON.
6. Check the voltage between ECM harness connector and ground.
Before measuring the terminal voltage, confirm that the battery is fully charged. Refer to PG-111, "How to Handle Battery".
Is the inspection result normal? YES >> INSPECTION END
NO >> Replace battery negative cable assembly. Refer to PG-125, "Exploded View".
