Is 1st trip DTC detected? YES >> Proceed to EC-329, "Diagnosis Procedure".
NO >> INSPECTION END
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 with CVT models *2: RHD with M/T models
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-330, "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".
