DTC Confirmation Procedure
1)Set ignition “ON”.
DTC Troubleshooting
| Step | Action | Yes | No |
|---|---|---|---|
| 1 |
Battery temperature sensor signal circuit and ground circuit check
1)Check that ignition is “OFF”.
2)Disconnect electric load current sensor & battery temperature sensor and “E24” connectors.
3)Check for proper terminal connection to electric load current sensor & battery temperature sensor and “E24” connectors.
4)If connections are OK, check the following points.
•Resistance of “A3” and “A4” circuits: less than 1 Ω
•Resistance between each of “A3” and “A4” circuits and ground: infinity •Resistance between each of “A3” and “A4” circuit terminals and other terminal at electric load current sensor & battery temperature sensor connector: infinity •Voltage of “A3” and “A4” circuits: approx. 0 V (When ignition is “ON”) Is check result OK?

Go to Step 2.
|
Repair or replace defective wire harness.

| 2 |
Battery temperature sensor check
1)Check electric load current sensor & battery temperature sensor.
Is check result OK?
|
Replace ENG A-STOP control module and recheck for DTC.
|
Replace electric load current sensor & battery temperature sensor.
