Tech Tips


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

  • These DTCs are stored when a malfunction is detected in the HV battery or a battery voltage sensor. However, depending on the driving conditions, the malfunction may not be reproduced if the condition of the HV battery changes.


    1. When the HV battery is malfunctioning:


      • - Voltage of 1 or more of the battery blocks has dropped.

        - Voltage of all battery blocks is output randomly with no certain pattern.

    2. When the battery voltage sensor is malfunctioning:


      • - While current is flowing to or from the HV battery, the voltage of a specific HV battery block will fluctuates.

  • 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 Hybrid Battery Cooling Parts at Your Dealer" is displayed on the multi-information display, make sure to perform the following items:


    • Make sure the air intake port is not blocked.

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

    • Clean the No. 1 HV battery intake filter.


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

Tech Tips


  • *1: Under normal conditions, the values of Hybrid Battery Block 1, 2, 8 and 9 Voltage will be approximately 16 V and Hybrid Battery Block 3, 4, 5, 6 and 7 Voltage will be approximately 32 V.

  • If there is a short or open in a battery block voltage detection line, the value of Hybrid Battery Block Voltage for the corresponding battery block will be lower than 8 V.

  • The Data List items Internal Resistance 1 to 9 indicate internal resistance correction values used by the hybrid vehicle control ECU to detect malfunctions of the HV battery.

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.

Click here


  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.

    Tech Tips

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

  7. Enter the following menus: Powertrain / Hybrid Control / 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 or N/A, perform driving pattern again.

CAUTION / NOTICE / HINT

CAUTION:

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.

      Tech Tips


      • If an internal malfunction occurs in the battery voltage sensor, the voltage of a specific hybrid battery block will fluctuate 0.2 V or more.

      • As changes in the voltage of hybrid battery blocks are difficult to see when the HV battery current is 0 A, read the Data List while the HV battery is being charged or discharged.

      • By displaying the Data List items for the corresponding circuit A battery block, circuit B battery block and circuit C battery block simultaneously, judgment can be performed more easily.

      • Make sure to set the graph display so that each graduation on the horizontal axis (time) indicates approximately 10 seconds.
