    3. With the vehicle stopped, apply the parking brake.
      NOTE:

      Perform this test with the AUTO function (shift-linked function) of the electric parking brake system off.

      HINT: 

      When the parking brake indicator (red) is illuminated after the electric parking brake switch assembly has been pulled to the lock side, the maximum amount of braking force is applied if the electric parking brake switch assembly is pulled to the lock side one more time.

    4. Turn the A/C switch off.
    5. Ensure the safety of the areas in front and at the back of the vehicle.
    6. Move the shift lever to D and depress both the accelerator pedal and brake pedal at the same time.
    7. Check the voltage of each "Hybrid Battery Block Voltage" of "Hybrid Battery Block 1 to 3 Voltage" and "Hybrid Battery Block 10 to 12 Voltage" in the Data List with the ignition switch ON (READY).
      NOTE:
      • When comparing the voltage of a circuit C battery block with that of a circuit A battery block or circuit B battery block, use half of the displayed voltage value for the circuit C battery block.

      HINT: 

      • If an internal malfunction occurs in the battery voltage sensor, the voltage of a specific hybrid battery block will fluctuate 0.2 V or more.
      • As changes in the voltage of hybrid battery blocks are difficult to see when the HV battery current is 0 A, read the Data List while the HV battery is being charged or discharged.
      • By displaying the Data List items for the corresponding circuit A battery block, circuit B battery block and circuit C battery block simultaneously, judgment can be performed more easily.
      • Make sure to set the graph display so that each graduation on the horizontal axis (time) indicates approximately 10 seconds.
