Tech Tips


  • These DTCs can be stored after clearing DTCs and driving the vehicle for approximately 10 minutes.

  • In order to ensure HV battery performance, appropriate cooling performance must be maintained. Perform the following items as necessary. If cooling performance has decreased and "Maintenance Required for Traction battery Cooling Parts See owner's manual" is displayed on the multi-information display, make sure to perform the following items:


    • Make sure the air intake port for HV battery is not blocked.


    • Make sure there are no gaps between the connecting parts of the ducts.


    • Clean the No. 1 HV battery intake filter and No. 2 HV battery intake filter.


      • Clear the DTCs to reset the learning values even if no DTCs are stored.

CONFIRMATION DRIVING PATTERN

Tech Tips

After repair has been completed, clear the DTC and then check that the vehicle has returned to normal by performing the following All Readiness check procedure.

  1. Connect the GTS to the DLC3.

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

  3. Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).

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

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

  6. Drive the vehicle on urban roads for approximately 10 minutes.

    (This DTC may not be stored if the vehicle is stopped or being driven at a constant speed.)

  7. Enter the following menus: Powertrain / HV Battery / Utility / All Readiness.

  8. 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.

    • If the judgment result shows INCOMPLETE, perform driving pattern again.

CAUTION / NOTICE / HINT

CAUTION:


  • B004STG

    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

  • B004Y5N

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

  • B004SX1

    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.

  • B004W3JC06
    *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.

    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.

  • Make sure to insulate the high-voltage connectors and terminals of the HV battery with insulating tape after removing it.

    If the HV battery stored without insulating the connectors and terminals, electric shock or fire may result.

  • B004SCIC06
    *a Dealer
    *b Battery Collection Agent

    When disposing of an HV battery, make sure to return it through an authorized collection agent who is capable of handling it safely. If the HV battery is returned via the manufacturer specified route, it will be returned properly and in a safe manner by an authorized collection agent.


    • Accidents such as electric shock may result if the HV battery is disposed of improperly or abandoned. Therefore, make sure to return all HV batteries through an authorized collection agent.

  • Before returning the HV battery, make sure to perform a recovery inspection.

  • Make a note of the output DTCs as some of them may be necessary for recovery inspection of the HV battery and HV supply stack sub-assemblies.

  • B004X4P

    After removing the HV battery, keep it away from water. Exposure to water may cause the HV battery to produce heat, resulting in a fire.

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.

PROCEDURE


  1. CHECK DTC OUTPUT (HV BATTERY)


    1. Connect the GTS to the DLC3.

    2. Turn the power switch on (IG).

    3. Enter the following menus: Powertrain / HV Battery / Trouble Codes.

    4. Check if DTCs are output.


      Powertrain > HV Battery > Trouble Codes
      Result
      Result Proceed to
      "P33DA1E" is output. A
      "P33DB1E" is output. B

    5. Turn the power switch off.

  2. CHECK TOTAL DISTANCE DRIVEN


    1. Read the odometer to check the total distance the vehicle has been driven.

      Result
      Result Proceed to
      Total distance driven is less than 200000 km (124280 mile) A
      Total distance driven is 200000 km (124280 mile) or more Current total distance driven - total distance driven when hybrid battery terminal block replaced = less than 200000 km (124280 mile) *1
      Other than above B

      Tech Tips

      *1: If the hybrid battery terminal block has been replaced, use the total distance driven since it was replaced.
