Refer to the description for DTC P1AC0-00.

Refer to DESCRIPTION 

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

        - Voltage of all hybrid battery blocks is output randomly with no certain pattern.

  2. When the battery voltage sensor is malfunctioning:
     1. - 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 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. 2 HV battery intake filter (LH side and RH side).
    1. Clear the DTCs to reset the learning values even if no DTCs are stored.

HINT: 

• *1: Under normal conditions, the values of Hybrid Battery Block 1, 2, 11 and 12 Voltage will be approximately 16 V and Hybrid Battery Block 3, 4, 5, 6, 7, 8, 9 and 10 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 12 indicate internal resistance correction values used by the hybrid vehicle control ECU to detect malfunctions of the HV battery.

The following items can be helpful when performing repairs:
