NO >> INSPECTION END
Diagnosis Procedure
1.CHECK BATTERY TEMPERATURE SENSOR POWER SUPPLY
- Turn ignition switch OFF
- Disconnect battery current sensor harness connector.
- Turn ignition switch ON.
- 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 BATTERY TEMPERATURE SENSOR POWER SUPPLY CIRCUIT
- Turn ignition switch OFF.
- Disconnect ECM harness connector.
- Check the continuity between battery current sensor harness connector and ECM harness connector.
- Also check harness for short to ground.
Is the inspection result normal? YES >> Perform the trouble diagnosis for power supply circuit.
NO >> Repair or replace error-detected parts.
3.CHECK BATTERY TEMPERATURE SENSOR GROUND CIRCUIT
- Turn ignition switch OFF.
- Disconnect ECM harness connector.
- Check the continuity between battery current sensor harness connector and ECM harness connector.
- 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 TEMPERATURE SENSOR
Check the battery temperature sensor. Refer to EC-387, "Component Inspection".
Is the inspection result normal? YES >> Check intermittent incident. Refer to GI-39, "Intermittent Incident".
NO >> Replace battery negative cable assembly.
Component Inspection
1.CHECK BATTERY TEMPERATURE SENSOR
- Turn ignition switch OFF.
- Disconnect battery current sensor.
- Check the resistance between battery current sensor connector terminals.
Is the inspection result normal? YES >> INSPECTION END
NO >> Replace battery negative cable assembly.
