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 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.
-
- Voltage of 1 or more of the battery blocks has dropped.
-
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.
-
When the HV battery is malfunctioning:
-
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 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.

CAUTION / NOTICE / HINT
CAUTION:
-
Before the following operations are conducted, take precautions to prevent electric shock by turning the power switch off, wearing insulated gloves, and removing the service plug grip from HV battery.

- Inspecting the high-voltage system
- Disconnecting the low voltage connector of the inverter with converter assembly
- Disconnecting the low voltage connector of the HV battery
-
To prevent electric shock, make sure to remove the service plug grip to cut off the high voltage circuit before servicing the vehicle.
-
After removing the service plug grip from the HV battery, put it in your pocket to prevent other technicians from accidentally reconnecting it while you are working on the high-voltage system.
-
After removing the service plug grip, wait for at least 10 minutes before touching any of the high-voltage connectors or terminals. After waiting for 10 minutes, check the voltage at the terminals in the inspection point in the inverter with converter assembly. The voltage should be 0 V before beginning work.

*a
Without waiting for 10 minutes
HINT:
Waiting for at least 10 minutes is required to discharge the high-voltage capacitor inside the inverter with converter assembly.
-
Make sure to insulate the high-voltage connectors and terminals of the HV battery with insulating tape after removing it.
If the HV battery stored without insulating the connectors and terminals, electric shock or fire may result.
-
When disposing of an HV battery, make sure to return it through an authorized collection agent who is capable of handling it safely. If the HV battery is returned via the manufacturer specified route, it will be returned properly and in a safe manner by an authorized collection agent.
*a
Dealer
*b
Battery Collection Agent
- Accidents such as electric shock may result if the HV battery is disposed of improperly or abandoned. Therefore, make sure to return all HV batteries through an authorized collection agent.
-
After removing the HV battery, keep it away from water. Exposure to water may cause the HV battery to produce heat, resulting in a fire.
NOTICE:
After turning the power switch off, waiting time may be required before disconnecting the cable from the negative (-) auxiliary battery terminal. Therefore, make sure to read the disconnecting the cable from the negative (-) auxiliary battery terminal notices before proceeding with work.
