Tech Tips

P3011-123 and P3027-123 will not be set unless the vehicle is driven for approximately 10 minutes after clearing the DTCs.

MONITOR DESCRIPTION

If there is an abnormal internal resistance or electromotive voltage in the battery blocks, the battery smart unit determines that a malfunction has occurred. When the malfunction detection condition is satisfied, the power management control ECU will illuminate the MIL and set a DTC.

MONITOR STRATEGY

Related DTCs P3011 to P3019 and P3020 to P3027 (INF 123): Battery cell malfunction

COMPONENT OPERATING RANGE

Battery smart unit DTC P3011 (INF 123) to P3019 (INF 123) and DTC P3020 (INF 123) to P3027 (INF 123) is not detected

CONFIRMATION DRIVING PATTERN

  1. Connect the Techstream to the DLC3.

  2. Turn the power switch on (IG) and turn the Techstream on.

  3. Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).

  4. Turn the power switch off.

  5. Turn the power switch on (READY) and turn the Techstream on.

  6. Perform a universal trip.

  7. Enter the following menus: Powertrain / Hybrid Control / Trouble Codes.

  8. Check that permanent DTCs are cleared.

    Tech Tips

    • If a permanent DTC is output, the system is malfunctioning.

    • If no permanent DTC is output, the system is normal.

INSPECTION PROCEDURE

CAUTION:

When disposing of an HV battery, make sure to return it through an authorized collection agent who is capable of handling it safely. If the HV battery is returned via the manufacturer specified route, it will be returned properly and in a safe manner by an authorized collection agent.

PROCEDURE

  1. CHECK DTC OUTPUT (HYBRID CONTROL)

    1. Connect the Techstream to the DLC3.

    2. Turn the power switch on (IG).

    3. Enter the following menus: Powertrain / Hybrid Control / Trouble Codes.

    4. Read output DTCs Click here.

  2. CHECK BATTERY SMART UNIT

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

    2. Connect the Techstream to the DLC3.

    3. Turn the power switch on (READY).

    4. Enter the following menus: Powertrain / Hybrid Control / Data List / Battery block Vol - V01 to V17.

    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 (Battery block Vol -V01 to V17) while fully depressing the accelerator pedal.

    9. Compare the battery block voltages (Battery block Vol -V01 to V17) 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 Battery block Vol - V16 V15 - V16
      Battery block Vol - V17 Battery block Vol - V14 V17 - V14

    10. Check the difference between each pair of battery block voltages.

      Result
      Result Proceed to
      Difference in voltage of all 9 pairs of blocks is 0.3 V or more. A
      Other than above. B

      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 9 pairs of blocks) will occur.
