HV RELAY ASSEMBLY INSTALLATION

PROCEDURE


  1. INSTALL HYBRID BATTERY JUNCTION BLOCK ASSEMBLY

    CAUTION:

    Wear insulated gloves.


    1. Install the hybrid battery junction block assembly with the 3 nuts.

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

    2. Connect the 4 connectors to the hybrid battery junction block assembly.

      Note

      The connectors should be connected securely.

    3. Connect the clamp.

  2. INSTALL NO. 2 HYBRID BATTERY SHIELD SUB-ASSEMBLY

    CAUTION:

    Wear insulated gloves.


    1. A005ATZE02

      Install the No. 2 hybrid battery shield sub-assembly with the 5 bolts.

      Torque:
      Bolt A
      7.5 N*m  { 76 kgf*cm, 66 in.*lbf }
      Bolt B
      19 N*m  { 194 kgf*cm, 14 ft.*lbf }

  5. CURRENT SENSOR OFFSET LEARNING

    Tech Tips

    Perform this procedure when the hybrid battery junction block assembly or power management control ECU has been replaced.


    1. Connect the GTS to the DLC3.

    2. Turn the power switch on (READY).

    3. Perform a road test.

      Note

      Accelerate/decelerate gently. Avoid rapid acceleration/deceleration.


      1. Enter the following menus: Powertrain / Hybrid Control / Data List / Power Resource IB.

      2. Drive the vehicle with the value of Data List item "Power Resource IB" between -50 A and 50 A.

      3. Distance and driving time are not specified.

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

      5. Turn the power switch on (IG).

      6. Enter the following menus: Powertrain / Hybrid Control / Data List / Power Resource IB.

      7. Check that the value of "Power Resource IB" 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


        • If the power switch is on (IG) and value of "Power Resource IB" 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.
