B → See step   6 

A: Go to next step 

1. Ensure the safety of the areas in front and at the back of the vehicle.
2. Apply the parking brake and secure the wheels using chocks.
3. Connect the Techstream to the DLC3.
4. Turn the ignition switch to ON (READY).
5. Fully warm up the engine and turn the air conditioning off.
6. Enter the following menus: Powertrain / Hybrid Control / Data List / Battery block Vol - V01 to V10.
7. Firmly depress the brake pedal with your left foot.
8. Move the shift lever to D.
9. Record each battery block voltage from the Data List "Battery Block Vol -V01 to V10" while fully depressing the accelerator pedal.
10. Compare the battery block voltages "Battery Block Vol - V01 to V10" between the even and odd number groups in each combination shown in the table below.
    TABLE 1
    
    

    Circuit A Battery Block	Circuit B Battery Block	Condition
    Battery Block Vol - V01 (VB1)	Battery Block Vol - V02 (VB2)	"Battery Block Vol - V01" - "Battery Block Vol - V02" = 0.3 V or more
    Battery Block Vol - V04 (VB4)	Battery Block Vol - V03 (VB3)	"Battery Block Vol - V04" - "Battery Block Vol - V03" = 0.3 V or more
    Battery Block Vol - V05 (VB5)	Battery Block Vol - V06 (VB6)	"Battery Block Vol - V05" - "Battery Block Vol - V06" = 0.3 V or more
    Battery Block Vol - V08 (VB8)	Battery Block Vol - V07 (VB7)	"Battery Block Vol - V08" - "Battery Block Vol - V07" = 0.3 V or more
    Battery Block Vol - V09 (VB9)	Battery Block Vol - V10 (VB10)	"Battery Block Vol - V09" - "Battery Block Vol - V10" = 0.3 V or more
