  2. CHECK BATTERY SMART UNIT


    1. Ensure the safety of the areas in front and at the back of the vehicle.

    2. Connect the intelligent tester to the DLC3.

    3. Turn the power switch on (READY).

    4. Enter the following menus: Powertrain / Hybrid Control / Data List / Battery Block Vol -V01 toV15.

    5. Fully warm up the engine and turn the air conditioning off.

    6. Firmly depress the brake pedal with your left foot.

    7. Move the shift lever to D.

    8. Record each battery block voltage from the data list (Battery Block Vol - V01 toV15) while fully depressing the accelerator pedal.

    9. Compare the battery block voltages (Battery Block Vol - V01 toV15) between the even and odd number groups in each combination shown in the table below.

      Odd Number Group Even Number Group Battery Block Voltages to be Compared
      Battery Block Vol - V01 Battery Block Vol - V02 V01 - V02
      Battery Block Vol - V03 Battery Block Vol - V04 V03 - V04
      Battery Block Vol - V05 Battery Block Vol - V06 V05 - V06
      Battery Block Vol - V07 Battery Block Vol - V08 V07 - V08
      Battery Block Vol - V09 Battery Block Vol - V10 V09 - V10
      Battery Block Vol - V11 Battery Block Vol - V12 V11 - V12
      Battery Block Vol - V13 Battery Block Vol - V14 V13 - V14
      Battery Block Vol - V15 - V15 - V13
      Battery Block Vol - V13

      Tech Tips

      Compare the V15 battery block voltage with the V13 battery block voltage.

    10. Check that the difference in voltage of each combination is 0.3 V or more.

      Result
      Result Proceed to
      Difference in voltage of all 8 pairs of blocks is 0.3 V or more. B
      Other than above. A

      Tech Tips

      When an internal malfunction occurs in the battery smart unit, this symptom (difference in voltage of 0.3 V or more for all 8 pairs of blocks) will occur.
