Activation
CAUTION:

Dynamic Response system components are manufactured to very precise tolerances. It is therefore essential that absolute cleanliness is observed when working with these components. Always install blanking plugs to any open orifices or lines. Failure to follow this instruction may result in foreign matter ingress to the dynamic response system.

NOTE:

This procedure should be carried out if the following components have been removed or replaced: front or rear stabilizer bar, front or rear valve block to actuator bar pipe assemblies, or the valve block. It is possible to bleed only the front or rear of the system if only a stabilizer bar or pipe assembly has been removed. If the valve block has been removed, the complete system must be bled.


  1. E62099
    Check and top-up the dynamic response system fluid reservoir. Top-up the fluid level to the mid-way mark on the reservoir.
  2. E62100
    Install the special tool to the dynamic response reservoir. Completely fill the reservoir with fluid. Make sure the pressure regulator on the special tool is turned OFF. Fill the special tool bottle approximately three-quarters full with fluid. Connect the special tool to a suitable workshop air supply.
    Special Tool(s): 204-591-01
  3. WARNING:

    Do not work on or under a vehicle supported only by a jack. Always support the vehicle on safety stands.

    Raise and support the vehicle.
  4. Remove the RH rear wheel and tire.
  5. E93348
    RH side rear: To improve access to RH rear actuator bleed screw, remove bracket from body frame securing fuel breather pipes.
  6. E62101
    Disconnect the two direction control valve electrical connectors.
  7. E62102
    Connect the special tool electrical connectors to the valve block. Connect the special tool power supply leads to the vehicle battery.
    Special Tool(s): 204-591-02
  8. Remove the engine undershield.
    Refer to: Engine Undershield (501-02 Front End Body Panels, Removal and Installation).
  9. E62103
    Connect the hose from special tool kit to the front stabilizer bar bleed screws. Remove the bleed screw covers.
  10. Loosen the front actuator RH bleed screw by one-half of a turn.
  11. E62104
    Using the special tool, open both actuator control valves.
    Special Tool(s): 204-591-02
  12. CAUTION:

    The Dynamic Response bleed tool fluid reservoir must remain full with new, clean fluid, at all times during bleeding.

    NOTE:

    It may be necessary to operate the switch several times to help pulse the air out of the actuator.

    E62105
    Bleed the dynamic response system until a flow of clean, air-free fluid, is being pumped into the bleed jar. Using the special tool pressure regulator, carefully increase the air pressure to approx. 5 - 10 PSI / 0.3 - 0.7 kPa, until air/fluid is being expelled from bleed screw.
  13. When a steady flow of clean air free fluid is running from the bleed point, tighten the bleed screw. Release the switch on the special tool to switch off the actuator control valves.
    Torque: 15Nm
  14. E62107
    Loosen the front actuator LH bleed screw by one-half of a turn.
  15. E62104
    Using the special tool, open both actuator control valves.
    Special Tool(s): 204-591-02
  16. NOTE:

    It may be necessary to operate the switch several times to help pulse the air out of the actuator.

    Bleed the dynamic response system until a flow of clean, air-free fluid, is being pumped into the bleed jar.
  17. When a steady flow of clean air free fluid is running from the bleed point, tighten the bleed screw. Release the switch on the special tool to switch off the actuator control valves.
    Torque: 15Nm
  18. Repeat the front stabilizer bar bleed procedure, from steps 9 to 17, a further two times, to make sure all air is removed from the actuator.
  19. Disconnect the special tool hose from the front stabilizer bar bleed screws. Install the bleed screw covers. Discard the fluid from the bleed jar.
  20. Install the engine undershield.
    Refer to: Engine Undershield (501-02 Front End Body Panels, Removal and Installation).
  21. Check and top-up the special tool fluid reservoir.
  22. E62109
    Connect the hose from the special tool kit to the rear stabilizer bar bleed screws. Remove the bleed screw covers.
  23. Loosen the rear actuator RH bleed screw by one-half of a turn.
  24. E62104
    Using the special tool, open both actuator control valves.
    Special Tool(s): 204-591-02
  25. CAUTION:

    The Dynamic Response bleed tool fluid reservoir must remain full with new, clean fluid, at all times during bleeding.

    NOTE:

    It may be necessary to operate the switch several times to help pulse the air out of the actuator.

    E62105
    Bleed the dynamic response system until a flow of clean, air-free fluid, is being pumped into the bleed jar.
  26. E62111
    When a steady flow of clean air free fluid is running from the bleed point, tighten the bleed screw. Release the switch on the special tool to switch off the actuator control valves.
    Torque: 15Nm
  27. E62111
    Loosen the rear actuator LH bleed screw by one-half of a turn.
  28. E62104
    Using the special tool, open both actuator control valves.
    Special Tool(s): 204-591-02
  29. NOTE:

    It may be necessary to operate the switch several times to help pulse the air out of the actuator.

    Bleed the dynamic response system until a flow of clean, air-free fluid, is being pumped into the bleed jar.
  30. When a steady flow of clean air free fluid is running from the bleed point, tighten the bleed screw. Release the switch on the special tool to switch off the actuator control valves.
    Torque: 15Nm
  31. Repeat the rear stabilizer bar bleed procedure, from steps 22 to 30, a further two times, to make sure all air is removed from the actautor.
