  1. CHECK DTC OUTPUT (HYBRID CONTROL)


    1. Connect the intelligent tester to the DLC3.

    2. Turn the power switch on (IG).

    3. Enter the following menus: Powertrain / Hybrid Control / DTC.

    4. Check if DTCs are output.

  2. CLEAN DUCT AND BLOWER


    1. B001MICC02
      *1 Intake Port

      Check that the No. 1 hybrid battery intake duct and battery cooling blower are not disconnected, damaged, or clogged with foreign matter, and that the acoustical materials have not peeled.

      Tech Tips

      If anything is blocking the HV battery cooling system intake port, remove it.

    2. Clean the No. 1 hybrid battery intake filter. (w/ No. 1 hybrid battery intake filter)

      Note


      • Clean the No. 1 hybrid battery intake filter with an air blow gun. Do not use water or any other liquid.

      • Do not use a wire brush or any other type of brush as it may damage the No. 1 hybrid battery intake filter.

      • To prevent removed foreign matter from entering the HV battery, make sure to remove the No. 1 hybrid battery intake filter when cleaning it.

  3. CHECK FREEZE FRAME DATA


    1. Connect the intelligent tester 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 INTELLIGENT TESTER


    1. Connect the Intelligent tester 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 TB3".

    4. According to the display on the intelligent tester, read the Data List and check that the value of each "Temp of Batt TB1 to TB3" is 40°C (104°F) or less.

      Tech Tips

      If the value of any of "Temp of Batt TB1 to TB3" is more than 40°C (104°F), turn the ignition 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 V14".

    6. According to the display on the intelligent tester, read the Data List and check the value of each "Battery Block Vol-V01 to V14" with the power switch on (IG).
