DTC No.	INF Code	DTC Detection Condition	Trouble Area
P3011 P3012 P3013 P3014	123	An internal malfunction of the HV battery is detected and the difference in voltage between each battery block or the internal resistance of each battery block is higher than the specified value. (1 trip detection logic)	HV battery Battery smart unit
P3015	123	An internal malfunction of the HV battery is detected and the difference in voltage between each battery block or the internal resistance of each battery block is higher than the specified value. (1 trip detection logic)	HV battery Battery smart unit Service plug grip
P3016 P3017 P3018 P3019 P3020	123	An internal malfunction of the HV battery is detected and the difference in voltage between each battery block or the internal resistance of each battery block is higher than the specified value. (1 trip detection logic)	HV battery Battery smart unit

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.
