POWER MANAGEMENT CONTROL ECU REMOVAL


  1. PRECAUTION

    Note

    After turning the power switch off, waiting time may be required before disconnecting the cable from the negative (-) auxiliary battery terminal. Therefore, make sure to read the disconnecting the cable from the negative (-) auxiliary battery terminal notices before proceeding with work Click here.

  2. WHEN REPLACING POWER MANAGEMENT CONTROL ECU

    HV battery learning values are stored in the power management control ECU and ECM to display "HAVE TRACTION BATTERY INSPECTED" on the multi-information display. When either of these ECUs is replaced, the new ECU receives the HV battery learning value data from the other ECU and updates the information.

    Note


    • Do not replace the power management control ECU and ECM at the same time as it clears the HV battery learning values. However, if it is necessary to replace both ECUs at the same time, replace them by following the procedure below.

    • Do not replace the power management control ECU or ECM with used ones from other vehicles.


    1. Procedure when replacing both power management control ECU and ECM:


      1. Disconnect the cable from the negative (-) auxiliary battery terminal.

      2. Replace either of the ECUs.

      3. Connect the cable to the negative (-) auxiliary battery terminal.

      4. Turn the power switch on (READY) and wait for 5 minutes or more.

      5. Turn the power switch off and disconnect the cable from the negative (-) auxiliary battery terminal.

      6. Replace the other ECU.

      7. Connect the cable to the negative (-) auxiliary battery terminal.

      8. Check that the power switch can be turned on (READY).

        Tech Tips

        If the power management control ECU and ECM are replaced at the same time without following the above procedure, replace either of the ECUs with its original one and then replace it again by following the above procedure. If the correct procedure is not followed, perform the procedure again from the beginning.
