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 EV battery or a battery voltage sensor. However, depending on the driving conditions, the malfunction may not be reproduced if the status of the EV 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).
- When the EV 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.
- When the battery voltage sensor is malfunctioning:
- - Differences in battery block voltages have a certain pattern.
- When the EV battery is malfunctioning:

In order to ensure EV 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 EV battery intake duct (filter).
Afterwards, clear the DTCs to reset the learning values even if no DTCs are stored.
