each damper to the appropriate level to maintain a flat and level body.
Roll Rate Control – Uses CAN inputs. Predicts vehicle roll rate due to driver steering inputs 100 times a second and increases damping to reduce roll rate.
Pitch Rate Control – Uses CAN inputs. Predicts vehicle pitch rate due to driver throttle and braking inputs 100 times a second and increases damping to reduce pitch rate.
Bump Rebound Control – Uses suspension height sensor and CAN inputs. Monitors the position of the wheel 500 times a second and increases the damping rate as the damper approaches the end of its travel.
Wheel Hop Control – Uses suspension height sensor and CAN inputs. Monitors the position of the wheel 500 times a second and detects when the wheel is at its natural frequency and increases the dampingto reduce vertical wheel
motion.
Under normal road conditions when the vehicle is stationary with the engine running, the dampers are set to the firm condition
to reduce power consumption.
The adaptive damping module receives its power supply via a relay and fuse in the CJB. The relay remains energized for a period of time after the ignition is off. This allows the adaptive damping module to record and store any DTC (diagnostic
trouble code) relating to adaptive dynamics system faults.
DAMPERS Component Description
Item Description A Front spring and damper assembly B Rear spring and damper assembly The 'Adaptive Dynamics' dampers are monotube, nitrogen gas and oil filled units, manufactured by Bilstein. The dampers are
continuously variable, which allows the damping force to be electrically adjusted when the vehicle is being driven. The variable
dampers provide the optimum compromise between vehicle control and ride comfort.
The dampers have an electrical connector on the end of the piston rod, in the center of the top mount (the dampers look
identical to those on the Computer Active Technology Suspension (CATS) system of 4.2L supercharged vehicles, but have a
different part number).
In each damper, the continuous damping adjustment is achieved by a solenoid operated variable orifice, which opens up an
alternative path for oil flow within the damper. When de-energized the bypass is closed and all the oil flows through the main
(firm) piston. When energized, the solenoid moves an armature and control blade, which work against a spring. The control
blade incorporates an orifice which slides inside a sintered housing to open up the bypass as required. In compression, oil
flows from the lower portion of the damper through a hollow piston rod, a separate soft (comfort) valve, the slider housing and
orifice and into the upper portion of the damper, thereby bypassing the main (firm) valve. In rebound the oil flows in the www.JagDocs.com
2 Main piston 3 Tube 4 Bypass valve (closed) 5 Piston and rod assembly ACCELEROMETERS
Three accelerometers are used in the adaptive dynamics system. The accelerometers are located as follows:
One each on the rear edge of the radiator support panel.
One in the luggage compartment, in the rear LH corner adjacent to the rear lamp assembly.
The accelerometers measure acceleration in the vertical plane and output a corresponding analogue signal to the adaptive
damping module. The algorithms in the adaptive damping module calculate the heave, pitch and roll motions of the vehicle,
which are used by the module to control road induced body modes.
Each accelerometer is connected to the adaptive damping module via three wires, which supply ground, 5 V supply and signal
return.
The sensing element comprises a single parallel plate capacitor, one plate of which moves relative to the other dependant on
the force (acceleration) applied. This causes the capacitance to change as a function of applied acceleration. This capacitance
is compared with a fixed reference capacitor in a bridge circuit and the signal is processed by means of a dedicated integrated
circuit to generate an output voltage that varies as a function of applied acceleration. The sensors output a signal voltage of
approximately 1 V/g ± 0.05 V/g.
SUSPENSION HEIGHT SENSORS
Four suspension height sensors are used in the adaptive dynamics system, two for the front suspension and two for the rear
suspension. A front suspension height sensor is attached to each side of the front subframes and connected by a sensor arm
and sensor link to the related lower lateral arm of the front suspension. A rear suspension height sensor is attached to each
side of the rear subframe and connected by a sensor arm and sensor link to the related upper control arm of the rear
suspension. On each suspension height sensor, the sensor arm and sensor link convert linear movement of the suspension into
rotary movement of the sensor shaft.
The sensors are also used for the static dynamic headlamp leveling system on vehicles fitted with xenon headlamps.
The suspension height sensors measure suspension displacement at each corner of the vehicle and output a corresponding
analogue signal to the adaptive damping module. The algorithms in the adaptive damping module calculate the position,
velocity and frequency content of the signals and use the results for wheel control.
Each suspension height sensor is connected to the adaptive damping module via three wires, which supply ground, 5 V supply

place and tightened to the specified torque; however, the bearing
shells should not be installed.
Measure the cylinder bore with an internal micrometer.

CAUTIONS:
If the control module or a component is suspect and the vehicle remains under manufacturer warranty, refer to the
warranty policy and procedures manual (section B1.2), or determine if any prior approval programme is in operation, prior to
the installation of a new module/component.
Diagnosis by substitution from a donor vehicle is NOT acceptable. Substitution of control modules does not guarantee
confirmation of a fault, and may also cause additional faults in the vehicle being tested and/or the donor vehicle
