    3. Connect the control valve connector.

    4. A015ANFE01

      Connect the wire harness clamp to the control valve bracket.

    5. Install a new gasket to the No. 4 suspension control pressure hose, and connect the hose to the control valve with the union bolt.

      Torque:
      50 N*m  { 510 kgf*cm, 37 ft.*lbf }
    6. A015B02E01

      Using a union nut wrench, connect the No. 4 height control tube to the control valve.

      Torque:
      without union nut wrench
      44 N*m  { 450 kgf*cm, 33 ft.*lbf }
      with union nut wrench
      40 N*m  { 408 kgf*cm, 30 ft.*lbf }

      Tech Tips


      • Use a torque wrench with a fulcrum length of 300 mm (11.8 in.).

      • The torque value for use with a union nut wrench is effective when the union nut wrench is parallel to the torque wrench.

  3. INSTALL REAR NO. 3 SUSPENSION CONTROL ACCUMULATOR LH


    1. Apply a small amount of suspension fluid to a new O-ring and new back-up ring and install them to the accumulator.

    2. A0157EU

      Install the No. 3 control accumulator to the control valve.

      Torque:
      150 N*m  { 1530 kgf*cm, 111 ft.*lbf }

  4. INSTALL REAR SUSPENSION CONTROL ACCUMULATOR ASSEMBLY LH


    1. Apply a small amount of suspension fluid to a new O-ring and install it to the accumulator.

    2. A015DFQ

      Install the control accumulator to the control valve.

      Torque:
      57 N*m  { 585 kgf*cm, 42 ft.*lbf }

  5. BLEED AIR FROM SUSPENSION FLUID


    1. A0159VG

      With the engine stopped, fill the reservoir tank with fluid.

      Note

      When the engine starts, the pump operates and fluid is supplied to each cylinder from the reservoir tank. Therefore, add the necessary amount of fluid so that the reservoir tank does not become empty.

      Tech Tips

      At this point, the vehicle height is low because the pressure of the cylinders is low.

    2. With the vehicle on a level surface, start the engine and set the vehicle height to NORMAL with the suspension control switch.

    3. When the vehicle height becomes NORMAL and the pump stops, stop the engine.

    4. A0157AZ

      Connect a hose to the bleeder plug of the front left side or right side control valve, then loosen the bleeder plug.

      CAUTION:

      Be careful when loosening the control valve bleeder plug because the front vehicle height drops rapidly.

    5. After the fluid containing air stops coming out, retighten the bleeder plug.

      Torque:
      8.3 N*m  { 85 kgf*cm, 73 in.*lbf }

      Tech Tips

      If the procedures are performed for the first time on the left side, perform the procedures on the right side for the second time.

    6. A015DJ3

      Connect a hose to the bleeder plug of the rear left side or right side control valve, then loosen the bleeder plug.

      CAUTION:

      Be careful when loosening the control valve bleeder plug because the rear vehicle height drops rapidly.

    7. After the fluid containing air stops coming out, retighten the bleeder plug.

      Torque:
      8.3 N*m  { 85 kgf*cm, 73 in.*lbf }

      Tech Tips

      If the procedures are performed for the first time on the left side, perform the procedures on the right side for the second time.

    8. Repeat the previous 4 procedures until the fluid containing air stop coming out.

  6. CHECK FLUID LEVEL IN RESERVOIR


    1. A0155HH

      With the vehicle empty, after setting the vehicle height to NORMAL from LO, check the indicator to make sure the vehicle height is NORMAL and check that the fluid level in the reservoir tank is within the specified range (MAX, MIN).

      Tech Tips

      After changing the vehicle height from LO to NORMAL, do not stop the engine for 25 seconds because the pressure control for the main accumulator is operating. After that, check the fluid level.

  7. INSPECT FOR SUSPENSION FLUID LEAK


    1. Check that the union nuts shown in the illustration are tightened to the specified torque.

      Torque:
      without union nut wrench
      15 N*m  { 155 kgf*cm, 11 ft.*lbf }
      with union nut wrench
      14 N*m  { 143 kgf*cm, 10 ft.*lbf }

      Tech Tips


      • Use a torque wrench with a fulcrum length of 300 mm (11.8 in.).

      • The torque value for use with a union nut wrench is effective when the union nut wrench is parallel to the torque wrench.

    2. Check for fluid leakage from the parts and connections.

      A015DN9E01

      Tech Tips

      For union nuts and union bolts not shown in the illustration, refer to the installation procedures for each title.

  8. INSTALL HEIGHT CONTROL UNIT PROTECTOR ASSEMBLY LH


    1. Install the protector pipe with the 6 bolts.

      Torque:
      16 N*m  { 163 kgf*cm, 12 ft.*lbf }
      A015BRP

  9. INSTALL SIDE STEP ASSEMBLY LH


    1. Install the side step with the 6 bolts.

      Torque:
      30 N*m  { 306 kgf*cm, 22 ft.*lbf }
      A0157CD
