Kia Soul EV (PS EV) 2015-2020 Service Manual / EV Battery System / High Voltage Battery Control System / High Voltage Battery Heater Temperature Sensor Repair procedures

Inspection

High voltage battery heater temperature sensor is installed in modules No. 1 and No. 8.

1. | Turn the ignition switch OFF.

2. | Shut off the high voltage. (Refer to Battery Control System - "High Voltage Shut-off Procedure")

3. | Remove the high voltage battery system assembly. (Refer to High Voltage Battery System - Repair procedures - "Removal")

4. | Remove the high voltage battery pack upper case. (Refer to High Voltage Battery System - Case - "Upper Case")

5. | Connect the SST (No: 0K918-E4100, 0K375-E4100, 0K375-E4200) as shown in the image beow.

6. | Connect the GDS to DLC.

7. | Turn the ignition switch ON.

8. | Check the "Heater Temperature" in the GDS service data.

9. | Turn the ignition switch OFF.

10. | Disconnect the SST (High voltage battery cable & BMS terminal).

11. | Check resistance for each temperature.
