HINT:
- These DTCs can be stored after clearing DTCs and driving the vehicle for approximately 10 minutes.
- 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 Traction Battery Cooling Parts See Owner's Manual" is displayed on the multi-information display, make sure to perform the following items:
- Make sure the air intake port for HV battery 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.
