HINT:

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 smart unit. However, depending on the driving conditions, the malfunction may not be reproduced if the status of the HV battery changes. If internal resistance is abnormal, the voltage of the battery blocks indicated by the DTCs are likely to decrease more than others blocks voltage during acceleration (discharging), and increase more during deceleration (charging).
1. When the HV battery is malfunctioning:
  - - Voltage of 1 or a few battery blocks has dropped.
  - - Voltage of all battery blocks is output randomly with no certain pattern.
2. When the battery smart unit is malfunctioning:
  - - Differences in battery block voltages have a certain pattern.
