Tech Tips

This DTC is stored when a malfunction is detected in the HV battery or battery voltage sensor. However, depending on the driving conditions, the malfunction may not be reproduced if the status of the HV battery changes. If resistance is abnormal, the voltage of the battery blocks indicated by the DTCs are likely to drop more than others during acceleration (discharging), and increase more than others during deceleration (charging).


  • When the HV battery is malfunctioning:


    • Voltage of one or a few of the battery blocks has dropped (voltage difference from that of the next block is 1 V or more).

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


  • When the battery voltage sensor is malfunctioning:


    • Differences in battery block voltages have a certain pattern.


  • If "Maintenance required for hybrid battery cooling parts at your dealer." is displayed on the multiinformation display, perform the following procedures.


    • Make sure the air intake port is not blocked.

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

    • Clean the battery cooling blower assembly filter.


      • Afterwards, clear the DTCs to reset the learning values even if no DTCs are stored.

INSPECTION PROCEDURE

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


  • P3011-123 to P3024-123 will not be set unless the vehicle is driven for approximately 10 minutes after clearing the DTCs.


  • After the repair, clear the DTCs and perform the following procedure to check that DTCs are not output.


    1. 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.
