  2. CHECK BATTERY SMART UNIT


    1. Make sure the areas in front and at the back of the vehicle are safe.

    2. Connect the intelligent tester to the DLC3.

    3. Turn the power switch on (READY).

    4. Select the following menu items: Powertrain / Hybrid Control / Data List / Battery Block Vol - V01 to V20.

    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 the D position.

    8. Record each battery block voltage in the data list ("Battery Block Vol - V01 to V20") while fully depressing the accelerator pedal.

    9. Compare the battery block voltages ("Battery Block Vol - V01 to V20") 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 Battery Block Vol - V01 - Battery Block Vol - V02
      Battery Block Vol - V03 Battery Block Vol - V04 Battery Block Vol - V03 - Battery Block Vol - V04
      Battery Block Vol - V05 Battery Block Vol - V06 Battery Block Vol - V05 - Battery Block Vol - V06
      Battery Block Vol - V07 Battery Block Vol - V08 Battery Block Vol - V07 - Battery Block Vol - V08

      Other than above B

      Tech Tips


      • The difference in the voltage of each combination may be 0.3 V or more due to a battery smart unit internal error.
