Disconnect electrical connector to height sensor and inspect
connector pins & terminals for evidence of corrosion or water
ingress. If no corrosion found, disconnect harness at Control
Module. A: Check for short circuits between any of the 3
terminals and vehicle ground. B: Check for electrical continuity
between the two connectors for each of the 3 terminals.
Reconnect electrical connector at Control Module only. C:
Check voltages at terminals within height sensor connector
(sensor not connected), with respect to vehicle body. •
Voltage to sensor ground connection should be ~0v • Voltage
to sensor signal connection should be ~0v • Voltage to sensor
supply connection should be ~5v All voltages should be within
± 0.15v C1A04-21

number is fitted, as specified in the service parts database.
To check height sensor: Disconnect electrical connector to
height sensor and inspect connecter pins & terminals for
evidence of corrosion or water ingress. If no corrosion found,
disconnect harness at Control Module. A: Check for short
circuits between any of the 3 terminals and vehicle ground. B:
Check for electrical continuity between the two connectors for
each of the 3 terminals. Reconnect electrical connector at
Control Module only. C: Check voltages at terminals within
height sensor connector (sensor not connected), with respect
to vehicle body. • Voltage to sensor ground connection should
be ~0v • Voltage to sensor signal connection should be ~0v •
Voltage to sensor supply connection should be ~5v All
voltages should be within ± 0.15v. To check sensor operation
on the vehicle: Check for water ingress around the height
sensors, electrical connectors or shaft end. Check for
excessive movement in the shaft in all directions. Raise
vehicle (ideally on wheels-free ramp) until suspension on
corner under investigation is at rebound to gain access to
height sensor. Access may be improved by removing road
wheel. Carefully disconnect the height sensor link from the
upper suspension arm. Monitor the height sensor signal
voltage output for the height sensor under investigation.
Position the sensor arm so it is in the mid position and
confirm that the voltage is around 2.5 volts. Move the sensor
arm over the range ±40° around the mid position and confirm
that the voltage changes smoothly between around 0.2 volts
and 4.8 volts. If voltages are incorrect or do not change
smoothly then replace sensor. NOTE: For angles of movement
beyond ±40°, the sensor signal will clamp to a voltage of
~0.15v or ~4.85v, depending on position of sensor lever. This
is normal. When investigation is complete, refit height sensor
link to upper arm. If any fixings to the height sensor body or
mounting bracket were slackened or found to be loose or if a
height sensor was changed, the vehicle ride height MUST be
re-calibrated. Refer to the relevant section of the workshop
manual for the calibration procedure C1A04-22

Description and Operation

OVERVIEW

Adaptive Dynamics - Supercharged Vehicles from 2010MY

The adaptive dynamics system, is an electronically controlled suspension system which constantly adjusts the damping
characteristics of the suspension dampers in reaction to the existing driving conditions. The adaptive dynamics system is
available on specified models.

The system is controlled by an Adaptive Damping Module (ADM), located beneath the right-hand front seat. The module
receives signals from three dedicated vertical accelerometers; two at the front of the vehicle and one at the rear, which,
together with four suspension height sensors, determine the state of the body and wheel motions. In addition to these inputs,
further signals from other vehicle electronic system components to determine vehicle state and driver inputs are monitored by
the adaptive damping module. These combined signals are used by the adaptive damping module to continuously adjust the
damping characteristics of each of the suspension dampers in reaction to the current driving conditions to give the optimum
body control and vehicle ride.

PRINCIPLES OF OPERATION System Operation

The adaptive damping module uses a combination of information from other system modules and data from the accelerometers
and suspension height sensors to measure the vehicle and suspension states and driver inputs. Using this information, the
adaptive damping module applies algorithms to control the dampers for the current driving conditions.
The adaptive damping module receives signals on the high speed CAN bus from the following system components: Brake Pressure - ABS module. Brake Pressure Quality Factor - ABS module. Car Configuration Parameters - AJB. Center Differential Range Actual - ECM. Engine Speed - ECM. Engine Speed Quality Factor - ECM. Engine Torque Flywheel Actual - ECM. Engine Torque Flywheel Actual Quality Factor - ECM. Gear Position Target - TCM. Lateral Acceleration - ABS module. Power Mode (Ignition Signal) - CJB. Power Mode Quality Factor - CJB. Roll Stability Control Mode - ABS module. Steering Wheel Angle - ABS module. Steering Wheel Angle Speed - ABS module. Steering Wheel Angle Status - ABS module. Terrain Mode Requested - JaguarDrive selector.
Torque Converter Slip - TCM. Vehicle Information Parameters HS - AJB Vehicle Speed - ABS module. Vehicle Speed Quality Factor - ABS module. Front Left Wheel Speed - ABS module. Front Left Wheel Speed Quality Factor - ABS module. Front Right Wheel Speed - ABS module. Front Right Wheel Speed Quality Factor - ABS module. Rear Left Wheel Speed - ABS module. Rear Left Wheel Speed Quality Factor - ABS module. Rear Right Wheel Speed Quality Factor - ABS module. Rear Right Wheel Speed - ABS module. The adaptive damping module also outputs information on the high speed CAN bus for use by other systems as follows: Fault Message - instrument cluster.
Terrain Mode Change Status - JaguarDrive selector.
Terrain Mode - JaguarDrive selector.

The adaptive damping module monitors the input signals and operates the damper solenoids. The input signals are used in
control modes and a force required for each damper for that mode is calculated. An arbitration mode monitors the force
requirements from each mode and apportions a force to a damper. The force is converted to the appropriate current and sent to
the damper.
The control modes are as follows:
