    1. Before inspecting the following areas or performing the following actions, turn the power switch off and take safety precautions such as wearing insulated gloves and removing the service plug grip to prevent electrical shocks.
      • High-voltage system
      • Quick charging system
      • Disconnecting the low voltage connector of the inverter with converter assembly
      • Disconnecting the low voltage connector of the electric vehicle charger assembly
      • Disconnecting the low voltage connector of the electric vehicle battery assembly
    2. After removing the service plug grip, put it in your pocket to prevent other technicians from accidentally reconnecting it while you are working on the high-voltage system.
      NOTE:
      • After turning the power switch off, waiting time may be required before disconnecting the cable from the negative (-) auxiliary battery terminal. Therefore, make sure to read the disconnecting the cable from the negative (-) auxiliary battery terminal notices before proceeding with work. Refer to PRECAUTION .
      • After removing the service plug grip, turning the power switch on (READY) may cause a malfunction. Do not turn the power switch on (READY) unless instructed by the repair information.
    3. After disconnecting the service plug grip, wait for at least 10 minutes before touching any of the high-voltage connectors or terminals.

      HINT: 

      Waiting for at least 10 minutes is required to discharge the high-voltage capacitor inside the inverter with converter assembly.

    4. Check the voltage at the terminals in the inspection point in the DC charger inlet cable. (w/ Quick Charging)
      WARNING:

      Be sure to wear insulated gloves.

      1. Open the charger lid.
      2. Open the DC charger inlet cable cap.
      3. Measure the voltage according to the value(s) in the table below.

        Tester Connection Condition Specified Condition
        Inspection point 10 minutes passed after removing the service plug 0 V

        HINT: 

        Set the tester to DC 750 V or more to measure the voltage.

    5. Check the voltage at the terminals in the inspection point in the inverter with converter assembly.
      WARNING:

      Be sure to wear insulated gloves.

      1. Remove the 9 bolts and inverter cover. Refer to COMPONENTS .
