  2. Disconnect high voltage. (Refer to High Voltage Battery Management System - "High Voltage Disconnection Procedure")
  3. Remove the high-voltage battery pack assembly. (Refer to High-Voltage Battery System - Repair Procedures - Removal).
  4. Remove the high-voltage battery upper cover. (Refer to High-Voltage Battery System - Housing - "Upper Case")
  5. Connect the SST (No.: 0K918-E4100, 0K375-E4100, 0K375-E4200) as shown in the illustration below.
  6. Connect GDS to the DLC.
  7. Turn the ignition on.
  8. Check the "Battery Module Temperature" in the GDS data.
  9. Turn the ignition off.
  10. Disconnect the SST (high-voltage battery cable and BMS terminal).
  11. Check the resistance of each temperature sensor.
