HV RELAY ASSEMBLY INSTALLATION

PROCEDURE


  1. INSTALL HV BATTERY JUNCTION BLOCK ASSEMBLY

    CAUTION:

    Be sure to wear insulated gloves and protective goggles.


    1. B004BIK

      Install the HV battery junction block assembly with the 4 nuts.

      Torque:
      7.5 N*m  { 76 kgf*cm, 66 in.*lbf }

      Note


      • Do not drop the HV battery junction block assembly, strike it with tools or subject it to impact.

      • If the HV battery junction block assembly is subjected to an impact, replace it with a new one.

    2. Connect the 4 connectors.

      Note

      Make sure that the connector is connected securely.

  5. PERFORM CURRENT SENSOR OFFSET LEARNING

    Tech Tips

    Perform this procedure when the HV battery junction block assembly or battery ECU assembly has been replaced.


    1. Connect the GTS to the DLC3.

    2. Turn the power switch on (READY).

    3. Perform a road test.

      Note

      Accelerate and decelerate gently. Avoid rapid acceleration and deceleration.


      1. Enter the following menus: Powertrain / HV Battery / Data List / Hybrid Battery Current.


        Powertrain > HV Battery > Data List
        Tester Display
        Hybrid Battery Current

      2. Drive the vehicle with the value of Data List item "Hybrid Battery Current" between -50 A and 50 A.

        Tech Tips

        Distance and driving time are not specified.

      3. Turn the power switch off and leave the vehicle for 30 seconds or more.

      4. Turn the power switch on (IG).

      5. Enter the following menus: Powertrain / HV Battery / Data List / Hybrid Battery Current.


        Powertrain > HV Battery > Data List
        Tester Display
        Hybrid Battery Current

      6. Check that the value of "Hybrid Battery Current" is between -0.5 A and 0.5 A with the power switch on (IG).

        Note

        If the value is outside the specified range, perform the road test again.

        Tech Tips


        • When the power switch is on (IG), if value of "Hybrid Battery Current" is between -0.5 A and 0.5 A, current sensor offset learning has been completed.

        • Even if the current sensor offset learning is not complete, the current sensor value will be corrected by repeating the road test a maximum of 7 times.
