INSPECTION PROCEDURE

PROCEDURE


  1. CHECK DTC OUTPUT (HV)


    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. Check if DTCs are output.

  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 / Batt block Vol -V01 to V14.

    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 select lever to D.

    8. Record each battery block voltage from the data list (Batt block Vol -V01 to V14) while fully depressing the accelerator pedal.

    9. Compare the battery block voltages (VB0 to 13 Batt block) between the even and odd number groups in each combination shown in the table below.

      Even Number Group Odd number group Battery block voltages to be compared
      V0 BATT BLOCK V1 BATT BLOCK VB0 - VB1
      V2 BATT BLOCK V3 BATT BLOCK VB2 - VB3
      V4 BATT BLOCK V5 BATT BLOCK VB4 - VB5
      V6 BATT BLOCK V7 BATT BLOCK VB6 - VB7
      V8 BATT BLOCK V9 BATT BLOCK VB8 - VB9
      V10 BATT BLOCK V11 BATT BLOCK VB10 - VB11
      V12 BATT BLOCK V13 BATT BLOCK VB12 - VB13

    10. Check the difference in voltage of each combination.

      Result
      Result Proceed to
      Difference in voltage of each combination is 0.3 V or higher. A
      Other than above. B

      Tech Tips

      If the difference in voltage of each combination is 0.3 V or higher, it is due to a battery smart unit internal error.

    11. Turn the power switch off.

    12. Disconnect the intelligent tester from the DLC3.
