Tech Tips

These DTCs can be stored after clearing DTCs and driving the vehicle for approximately 10 minutes.
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).
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 "Hybrid Battery Cooling Warning" 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

*1: Under normal conditions, the values of Hybrid Battery Block 1, 2, 8 and 9 Voltage will be approximately 16 V and Hybrid Battery Block 3, 4, 5, 6 and 7 Voltage will be approximately 32 V.
If there is a short or open in a battery block voltage detection line, the value of Hybrid Battery Block Voltage for the corresponding battery block will be lower than 8 V.
The Data List items Internal Resistance 1 to 9 indicate internal resistance correction values used by the hybrid vehicle control ECU to detect malfunctions of the HV battery.

CONFIRMATION DRIVING PATTERN

Tech Tips

After repair has been completed, clear the DTC and then check that the vehicle has returned to normal by performing the following All Readiness check procedure.

Click here

Connect the GTS to the DLC3.
Turn the power switch on (IG) and turn the GTS on.
Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
Turn the power switch off and wait for 2 minutes or more.
Turn the power switch on (IG) and turn the GTS on.
Drive the vehicle on urban roads for approximately 10 minutes.

Tech Tips

This DTC may not be stored if the vehicle is stopped or being driven at a constant speed.
Enter the following menus: Powertrain / Hybrid Control / Utility / All Readiness.
Check the DTC judgment result.
Tech Tips
- If the judgment result shows NORMAL, the system is normal.
- If the judgment result shows ABNORMAL, the system has a malfunction.
- If the judgment result shows INCOMPLETE or N/A, perform driving pattern again.

CAUTION / NOTICE / HINT

CAUTION:

*a Dealer

*b Battery Collection Agent

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.

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.

PROCEDURE

CHECK DTC OUTPUT (HYBRID CONTROL)

Connect the GTS to the DLC3.
Turn the power switch on (IG).
Enter the following menus: Powertrain / Hybrid Control / Trouble Codes.

Check for DTCs.
