DTC P0ABF-2A: Hybrid/EV Battery Current Sensor "A" Signal Stuck In Range [04/2018 - 08/2020]: Procedure

WARNING: This page is about a different car, the 2020 Toyota Avalon and 2019 Toyota Avalon. However, it is still accessible from the selected car via links, so may be relevant.
  1. CHECK DTC OUTPUT (HYBRID CONTROL) 
    1. Connect the Techstream to the DLC3.
    2. Turn the power switch on (IG).
    3. Enter the following menus: Powertrain/Hybrid Control/Trouble Codes.
    4. Check and record any HV system DTCs and freeze frame data.

      Powertrain > Hybrid Control > Trouble Codes

  2. READ VALUE USING TECHSTREAM 
    1. Connect the Techstream to the DLC3.
    2. Turn the power switch on (IG).
      NOTE:

      Do not turn the power switch on (READY).

    3. Enter the following menus: Powertrain/Hybrid Control/Data List/Hybrid Battery Block 1 to 11 Voltage.
      NOTE:

      Select "Hybrid Battery Block 1 to 11 Voltage" only. (Do not select any other Data List items.)

      Powertrain > Hybrid Control > Data List 

      Tester Display
      Hybrid Battery Block 1 Voltage
      Hybrid Battery Block 2 Voltage

      Specified Condition

      Any "Hybrid Battery Block Voltage" changes by 0.3 V or more, 60 seconds after the power switch is turned on (IG). (The difference between the maximum and minimum voltage is 0.3 V or more.)

      Result

      Result Proceed to
      The change in voltage of any "Hybrid Battery Block Voltage" is 0.3 V or more. A
      Other than above B
    5. Turn the power switch off.

    Result: 

    A 

    REPLACE BATTERY VOLTAGE SENSOR. Refer to  REMOVAL [04/2018 - 08/2020] 

    Result: 

    B 

    REPLACE HV BATTERY JUNCTION BLOCK ASSEMBLY. Refer to  REMOVAL [04/2018 - 08/2020]
