Tech Tips

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 voltage sensor. However, depending on the driving conditions, the malfunction may not be reproduced if the condition of the HV battery changes.

When the HV 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:

- While current is flowing to or from the HV battery, the voltage of a specific HV battery block will fluctuates.

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 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 HV battery intake filter.

Clear the DTCs to reset the learning values even if no DTCs are stored.

Tech Tips

If an internal malfunction occurs in the battery voltage sensor, the voltage of a specific hybrid battery block will fluctuate 0.2 V or more.
As changes in the voltage of hybrid battery blocks are difficult to see when the HV battery current is 0 A, read the Data List while the HV battery is being charged or discharged.
By displaying the Data List items for the corresponding circuit A battery block, circuit B battery block and circuit C battery block simultaneously, judgment can be performed more easily.
Make sure to set the graph display so that each graduation on the horizontal axis (time) indicates approximately 10 seconds.
