  4. Enter the following menus: Powertrain / Hybrid Control / Data List.

  5. Check that "Hybrid Battery SOC" shows 70% or less.

  6. Turn the power switch off and wait for 2 minutes or more.

  7. Connect the electric vehicle charger cable assembly, and plug-in charge the vehicle for 30 seconds or more.

  8. Disconnect the electric vehicle charger cable assembly and wait for 10 seconds or more.

  9. Connect the electric vehicle charger cable assembly, and plug-in charge the vehicle for 30 seconds or more.

  10. Disconnect the electric vehicle charger cable assembly and wait for 10 seconds or more.

  11. Turn the power switch on (IG) and turn the GTS on.

  12. Enter the following menus: Powertrain / Plug-in Control / Utility / All Readiness.

  13. Check the DTC judgment result.

    Tech Tips


    • If the judgment result shows NORMAL, the system is normal.

    • If the judgment result shows ABNORMAL, the system has a malfunction.

CAUTION / NOTICE / HINT

CAUTION:


  • B006HUP

    Before the following operations are conducted, take precautions to prevent electric shock by turning the power switch off, wearing insulated gloves, and removing the service plug grip from HV battery.


    • Inspecting the high-voltage system

    • Disconnecting the low voltage connector of the inverter with converter assembly

    • Disconnecting the low voltage connector of the HV battery

    • Disconnecting the low voltage connector of the electric vehicle charger assembly

    • Disconnecting the low voltage connector of the solar energy control unit

  • B006IQP

    To prevent electric shock, make sure to remove the service plug grip to cut off the high voltage circuit before servicing the vehicle.

  • B006HQC

    After removing the service plug grip from the HV battery, put it in your pocket to prevent other technicians from accidentally reconnecting it while you are working on the high-voltage system.

  • B006IVPC05
    *a Without waiting for 10 minutes

    After removing the service plug grip, wait for at least 10 minutes before touching any of the high-voltage connectors or terminals. After waiting for 10 minutes, check the voltage at the terminals in the inspection point in the inverter with converter assembly. The voltage should be 0 V before beginning work.

    Click here

    Tech Tips

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

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.
