    1. Tighten the nut.

      Torque:
      185 N*m  { 1886 kgf*cm, 136 ft.*lbf }

      Note

      Perform this procedure with all 4 wheels on the ground.

  6. INSTALL FRONT HEIGHT CONTROL SENSOR SUB-ASSEMBLY LH (w/ Active Height Control)


    1. A0155YW

      Install the sensor with the bolt and nut.

      Torque:
      for bolt
      13 N*m  { 127 kgf*cm, 9 ft.*lbf }
      for nut
      5.6 N*m  { 57 kgf*cm, 50 in.*lbf }

    2. Connect the connector.

  7. INSTALL FRONT FENDER APRON TRIM PACKING D


    1. A0155HI

      Install the apron trim packing with the 4 clips.

  8. INSTALL FRONT FENDER APRON TRIM PACKING B (w/ KDSS)


    1. A015AWE

      Install the apron trim packing with the 3 clips.

  9. INSTALL FRONT FENDER APRON TRIM PACKING B (w/o KDSS)


    1. A015E8N

      Install the apron trim packing with the 4 clips.

  10. CONNECT CABLE TO NEGATIVE BATTERY TERMINAL (w/ Active Height Control)

    Note

    When disconnecting the cable, some systems need to be initialized after the cable is reconnected Click here.

  11. PERFORM VEHICLE HEIGHT OFFSET CALIBRATION (w/ Active Height Control)


    1. Perform the vehicle height offset calibration Click here.

  12. ADJUST FRONT HEIGHT CONTROL SENSOR SUB-ASSEMBLY LH (w/ Active Height Control)

    Note


    • Make adjustments from the link that deviates the most from the specified vehicle height value.

    • When the front and rear are at the same level, make adjustments from the front first.

    • If adjustment cannot be completed through the vehicle height offset calibration, adjust the sensor link using the following procedure.


    1. A0158H1

      Loosen the nut and adjust the link installation position by moving the height control sensor link up or down in the long hole of the bracket.

      Tech Tips

      When the link is moved 1 mm (0.0394 in.), the vehicle height changes by approximately 2 mm (0.0787 in.).

    2. Tighten the nut of the height control sensor link.

      Torque:
      5.6 N*m  { 57 kgf*cm, 50 in.*lbf }

  13. PERFORM ZERO POINT CALIBRATION OF G SENSOR (w/ Active Height Control)


    1. Perform the zero point calibration of G sensor Click here.

  14. MEASURE VEHICLE HEIGHT (w/ KDSS)

    Note


    • Perform the inspection on a level surface.

    • Ensure that the wheels are on the ground and facing straight ahead.

    • Perform the inspection with the vehicle load completely on the suspension.

    Tech Tips


    • Perform this step with the fuel tank full.

    • If there are any parts installed to the vehicle which place any unbalanced load on the left or right side of the vehicle, remove them.


    1. Set the tire pressure to the specified value(s) Click here.

    2. Bounce the vehicle to stabilize the suspension.

    3. A015AG2

      Measure the distance from the ground to the top of the bumper and calculate the difference in the vehicle height between left and right. Perform this procedure for both the front and rear wheels.

      Height difference of left and right sides
      15 mm (0.591 in.) or less

      Tech Tips

      If not as specified, perform the vehicle tilt calibration.

  15. CLOSE STABILIZER CONTROL WITH ACCUMULATOR HOUSING SHUTTER VALVE (w/ KDSS)

    Note


    • Perform the inspection on a level surface.

    • Ensure that the wheels are on the ground and facing straight ahead.

    • Perform the inspection with the vehicle load completely on the suspension.

    Tech Tips


    • Perform this step with the fuel tank full.

    • If there are any parts installed to the vehicle which place any unbalanced load on the left or right side of the vehicle, remove them.


    1. Using a 5 mm hexagon socket wrench, tighten the lower and upper chamber shutter valves of the stabilizer control with accumulator housing.
