CAUTION / NOTICE / HINT

CAUTION:

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.

Tech Tips

After the repair, clear the DTCs and perform the following procedure to check that DTCs are not output.


  1. Drive the vehicle for approximately 10 minutes according to the freeze frame data items "Vehicle Spd", "Temp of Batt TB1 to TB6", "Inhaling Air Temp", "Ambient Temperature" and "Power Resource IB".

PROCEDURE


  1. CHECK DTC OUTPUT (HYBRID CONTROL)


    1. Connect the GTS to the DLC3.

    2. Turn the power switch on (IG).

    3. Enter the following menus: Powertrain / Hybrid Control / Trouble Codes.

    4. Check for DTCs.


      Powertrain > Hybrid Control > Trouble Codes
      Result
      Proceed to
      P3000-603 only is output.
      DTCs other than P3000-603 are also output.

    5. Turn the power switch off.


    DTCs other than P3000-603 are also output.

  3. CHECK FREEZE FRAME DATA (HYBRID CONTROL)


    1. Connect the GTS to the DLC3.

    2. Turn the power switch on (IG).

    3. Enter the following menus: Powertrain / Hybrid Control / Trouble Codes.

    4. Read the freeze frame data of DTC P3000-603.

      Note

      Although freeze frame data is recorded before and after a DTC is stored, for this step it is only necessary to read the freeze flame data recorded before "0s" (when the DTC was stored).

  5. READ VALUE USING GTS


    1. Connect the GTS to the DLC3.

    2. Turn the power switch on (IG).

    3. Enter the following menus: Powertrain / Hybrid Control / Data List / "Temp of Batt TB1 to TB6".

    4. According to the display on the GTS, read the Data List and check that the value of each "Temp of Batt TB1 to TB6" is 40°C (104°F) or less.

      Tech Tips

      If the value of any of "Temp of Batt TB1 to TB6" is more than 40°C (104°F), turn the power switch off and wait until the values to decrease to 40°C (104°F) or less before continuing this procedure.

    5. Enter the following menus: Powertrain / Hybrid Control / Data List / "Battery Block Vol - V01 to V17".

    6. According to the display on the GTS, read the Data List and check the value of each "Battery Block Vol-V01 to V17" with the power switch on (IG).
