GO to J6. No
If agreed with the customer install correct tire low pressure sensors in accordance with that defined in
the manufacturer approved diagnostic system new tire low pressure sensor application, as required.
(Note: Confirm why the vehicle has non-Tire Pressure Monitoring System w he e l & tire assemblies installed before installing tire low
pressure sensors, which are not to be claimed under vehicle warranty.) J6: C1D1987 CHECK TIRE SENSOR COMPATIBILITY TO TIRE PRESSURE MONITORING SYSTEM RECEIVER 1 Remove tire low pressure sensor from 1 wheel. 2 Verify the tire low pressure sensor part number from the information on the casing. Is the tire low pressure sensor the correct part for the vehicle? Yes

Remove the Tire Pressure Monitoring System power supply fuse and re-install it. Clear DTCs and leave
the vehicle stationary for 15 minutes, then drive it at a speed greater than 15.5 mph (25 kph)
continuously for at least 10 minutes.
(Note: If the vehicle spe e d drops below this value, the drive time to complete the test will need to be increased. The use of the manufacturer approved diagnostic system, and the datalogger signal ’Tire pressure monitor system status – learn mode status’ will verify the completion of the test w he n the value returns to ‘Inactive’.)
No
Install the correct tire low pressure sensor, of correct frequency, in accordance with that defined in the
manufacturer approved diagnostic system new tire low pressure sensor application, to the position(s)
identified.
(Note: Confirm why the vehicle has incorrect Tire Pressure Monitoring System w he e l & tire assemblies installed before installing tire low
pressure sensors, which are not to be claimed under vehicle warranty.)

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

System Fault Message

The adaptive damping module has a high speed CAN connection to the instrument cluster. If a fault is detected by the adaptive damping module, a message is sent to the instrument cluster and the message 'ADAPTIVE DYNAMICS FAULT' is
displayed. The adaptive damping module also logs an appropriate DTC. The adaptive damping module can be interrogated using an approved Jaguar diagnostic system.

When a fault is detected, the adaptive damping module implements a strategy based on the type of fault. If there is an
electrical power fault, or the adaptive damping module cannot control the dampers, they default to the firm condition. If a
sensor fails that only affects one or more control modes then an intermediate damper setting is used as the lower threshold
and the remaining working modes can demand higher damping as required.

Inspection and Verification

Visually examine the front and rear wheel and tire assemblies for damage such as uneven wear patterns, tread worn out or
sidewall damage. Verify the tires are the same size, type and, where possible, same manufacturer. Replace the damaged
wheel or excessively worn tire.
Wheels and tires must be cleared of any foreign matter and tire pressures adjusted to the correct specification.

If the tires exhibit uneven wear or feathering, the cause must be corrected. Check the steering and suspension components for
damage or wear and, if necessary, check and adjust front wheel alignment. REFER to: (204-00 Suspension System - General
Information)

Carry out a road test to compare actual vehicle braking performance with the performance standards expected by the driver.
The ability of the test driver to make valid comparisons and detect performance deficiencies will depend on experience.

The driver should have a thorough knowledge of brake system operation and accepted general performance guidelines to make
good comparisons and detect performance concerns.

An experienced brake technician will always establish a route that will be used for all brake diagnosis road tests. The roads
selected will be reasonably smooth and level. Gravel or bumpy roads are not suitable because the surface does not allow the
tires to grip the road equally. Crowned roads should be avoided because of the large amount of weight shifted to the low set
of wheels on this type of road. Once the route is established and consistently used, the road surface variable can be
eliminated from the test results.

Before a road test, obtain a complete description of the customer concerns or suspected condition. From the description, the
technician's experience will allow the technician to match possible causes with symptoms. Certain components will be tagged
as possible suspects while others will be eliminated by the evidence. More importantly, the customer description can reveal
unsafe conditions which should be checked or corrected before the road test. The description will also help form the basic
approach to the road test by narrowing the concern to specific components, vehicle speed or conditions.

Begin the road test with a general brake performance check. Keeping the description of the concern in mind, test the brakes at
different vehicle speeds using both light and heavy pedal pressure. To determine if the concern is in the front or rear braking
system, use the brake pedal and then use the parking brake control. If the condition (pull, vibration, pulsation) occurs only
with the parking brake, the concern is in the rear brake system.
