  • B004STG

    To prevent electric shock, wear insulated gloves when working on wire harnesses and components of the high voltage system.

Note


  • The type of battery voltage sensor to be used varies depending on the vehicle model.

  • B004WIIC01
    *a Black Label

    The type of battery voltage sensor can be confirmed by the color of the label.

  • If the wrong type of battery voltage sensor is installed, the power switch cannot be turned on (READY).

  • After installing the battery voltage sensor, perform the following to check that the power switch can be turned on (READY).


    • Turn the power switch on (READY).

    • Turn the power switch off and wait for 30 seconds or more.

    • Turn the power switch on (READY) again.

  9. REMOVE BATTERY VOLTAGE SENSOR (for Upper Side)

    CAUTION:


    • Be sure to wear insulated gloves and protective goggles.

    • High voltage is output to the battery ECU assembly from the battery voltage sensor (for Upper Side). As a result, detach the wire harness (No. 1 HV supply stack sub-assembly) cell voltage detection circuit first.


    1. B004WIR

      Remove the 4 nuts and No. 1 HV battery protector (for upper side).

    2. B004RZ2N02

      Disconnect connector A and connector B on the wire harness (No. 1 HV supply stack sub-assembly) cell voltage detection circuit.

      CAUTION:

      Make sure to the disconnect the connector A and connector B on the wire harness (No. 1 HV supply stack sub-assembly) cell voltage detection circuit first.

      Note

      Insulate each disconnected high-voltage connector with insulating tape. Wrap the connector from the wire harness side to the end of the connector

    3. Disconnect connector C on the No. 1 hybrid battery pack wire side.

      CAUTION:

      Make sure to the disconnect the connector A and connector B on the wire harness (No. 1 HV supply stack sub-assembly) cell voltage detection circuit first.

      Note

      Insulate each disconnected high-voltage connector with insulating tape. Wrap the connector from the wire harness side to the end of the connector

    4. Remove the battery voltage sensor (for upper side).

      Note


      • Do not drop the battery voltage sensor (for upper side), strike it with tools or subject it to impact.

      • If the battery voltage sensor (for upper side) is subjected to an impact, replace it with a new one.

      Remove the 4 nuts and No. 1 HV battery protector (for lower side).

    2. B004U5RN02

      Disconnect connector A and connector B on the wire harness (No. 2 HV supply stack sub-assembly) cell voltage detection circuit.

      CAUTION:

      Make sure to the disconnect the connector A and connector B on the wire harness (No. 2 HV supply stack sub-assembly) cell voltage detection circuit first.

      Note

      Insulate each disconnected high-voltage connector with insulating tape. Wrap the connector from the wire harness side to the end of the connector

    3. Disconnect connector C on the No. 2 hybrid battery pack wire side.

      CAUTION:

      Make sure to the disconnect the connector A and connector B on the wire harness (No. 2 HV supply stack sub-assembly) cell voltage detection circuit first.

      Note

      Insulate each disconnected high-voltage connector with insulating tape. Wrap the connector from the wire harness side to the end of the connector

    4. Remove the battery voltage sensor (for lower side).

      Note
