tion
Th
e
system selects the soft or
firm damper setting according to the current ro ad and driving conditions, to optimise vehicle
ride and handling.
With the vehicle stationary, the dampers are in the firm setting, but will normally switch to the soft setting when the vehicle
exceeds 8 km/h (5 mile/h); all dampers are switched simultaneously.
Sudden movement of the vehicle body, in response to road inputs, is detected by the vertical accelerometers, and the ADCM
switches the dampers to the firm setting to give improved damping of the resultant oscillations.
When cornering forces are detected by th e lateral accelerometer, the ADCM switches the dampers to the firm setting to
reduce the roll rate an d improve wheel control.
After the event has passed, the dampers revert to the soft setting.
When the footbrake is applied, the ADCM re ceives a signal and calculates the rate of vehicle deceleration. If the deceleration
rate is greater than a certain threshold, the dampers are switched to the firm setting to reduce the pitch rate and improve
wheel control.
If a system failure occurs, the ADCM grounds the output line to the instrument cluster message center, which displays a
text warning SUSPENSION FAULT and illuminates the amber warning lamp. Under fault conditions the system always fails to
the firm setting, so that the vehicle will be safe to drive un der all road and driving conditions.

means of a manual adjustment
mechanism
at each set of shoes. Refer to General Procedur es in section 206-05.
If the vehicle is driven above 5 km/h with the parking brake applied, a warning lamp and text message will appear on the
message center. The message clears when the brake is released or the speed drops below 3 km/h.
Parking Brake Shoe Arrangement

The adjuster mech
anism enables manual
adjustment of the brake shoes.
Retai
ning pins keep the shoes in contact with the dust shield.
The brake

shoes locate into the expander lever and the adjuster mechanism.
R

turn springs retr
act the brake shoes when the parking brake is released.
Th
e expander lever mechanism moves the brake shoes outwar

Sidelam
ps and Headlamps
Thes
e are controlled by rotating the end of the column switch as follows.
In the OFF position:
All
exterior lamps are switched OFF.
In the sidelamp position:
The front
sidelamps, tail, license plate and any other la
mps required by local legislation are switched ON.
The
sidelamps tell-tale lamp illuminates.
In the headlamp position, with the ignition switch in position II:
The h
eadlamps are switched ON in addition to the lamps switched on in the sidelamp position.
If the ignition is switched to the OFF position with the column switch in the headlamp position, the sidelamps, tail and
license plate lamps will stay ON, but the headlamps will switch OFF.
In the AUTO position (where fitted), with the ignition switch in position II:
Th
e sensor mounted on the back of the interior rear view
mirror monitors exterior light levels and automatically
switches the sidelamps and di pped headlamps ON and OFF.
The sensitivity level can be adjusted by turn ing the sensor control knob on the back of the interior mirror, left to decrease or
right to increase. The sensor must not be covered and the windscreen must be kept clean.
Headlamp Main Bea
m Position
Wi
th the column switch in
the headlamp position:
Movin
g the switch stalk away fro
m the steering wheel switches the headlamps to main beam.
Movin
g the switch stalk towards the steering wheel switches the headlamps to dipped beam.
The main beam tell-tale lamp illuminates when the headlamps are switched to main beam.
Ma
in Beam Flash
Wi
th the ignition switch and column switch in any position:
Pulling the

switch stalk agains
t spring pressure towards th e steering wheel illuminates the headlamps on main beam
for as long as the switch is held.
The main beam tell-tale lamp illuminates while the headlamps are illuminated.
M
essage Center Functions
T
he message center functions:
Are se

lected by the button located at the end of the lighting switch stalk.
Are se

lected in turn, by repeatedly pressing the button,
from the odometer reading, through the trip computer data
in sequence, and back to th e odometer reading again.

The wiper and washer switch i s
on the righ
t-hand side of the steering column and controls the fo llowing functions when the
ignition switch in position II.
In the OFF position:
The windscreen wiper is stationary and in the parked positio
n.
In the intermittent wipe position:
The wi per ope
rates intermittently, with
a variable time delay between wipes.
The time del
ay can be varied by rotating the column sw
itch collar, which has six positions and varies the delay
between two and 20 seconds. The collar is turned counter-clockwise to increase the delay.
In the normal speed position:
The wiper oper a
tes continuously at normal speed.
In the high speed position:
The wiper ope r
ates continuously at high speed.
Flick wipe operation:
Is obt
ained by pulling the switch
stalk towards the steering wheel.
F
e
atures a single wipe at normal speed if
the switch stalk is released immediately.
Fe
atures continuous wipe action
at normal speed while the swit ch stalk position is held.
Wash/W
ipe Operation
Th
e
wash/wipe function:
Is operat
ed by th
e button at the end of the switch stalk.
Op
erate
s the washers and wiper, while the butt
on is depressed, for up to 20 seconds.
Provides an addit
ional three sweeps of
the wiper after the button is released.
Provid
es a single drip-wipe sweep, four seconds af
ter the wash/wipe sequence has been completed.
Is disabled if the 'Washer Flu
id Low' message is di
splayed, but manual operat ion is still available.

spection and Verification
1.
1. Veri fy the customer concern.
2. 2. Confi
rm which, if any, warning li
ghts and/or messages were displayed on the instrument cluster.
• NOTE: If any warning lights and/or me ssages were displayed when the fault occurred, refer to the Driver Information
table for DTCs associated with the display, then to the DTC index table for possible sources and actions. Some warnings will
appear to clear when the ignition is cycl ed. This is often because the warning has flagged as a resu lt of one of the vehicle's
on-board diagnostic routines having run to detect the fault. If the same routine is not run when the ignition is switched ON,
the warning will not reflag until the routine does run. See the DTC summaries for drive cycle routines.
3. 3. Visually inspect for obvious signs of mechanical or electrical damage.
Vi
sual Inspection Chart
4.
4. Veri fy the foll
owing syst
ems are working correctly:
Air intake
system
Cooling system


Charging system
5. 5. If
an obvious cause for an observed or
reported concern is found, correct th e cause (if possible) before proceeding
to the next step.
6. 6. Where the Jaguar approved diagnostic sy stem is available, complete the S93 report before clearing any or all fault
codes from the vehicle.
• NOTE: If a DTC cannot be cleared, then there is a permanent fault present that flag s again as soon as it is cleared (the
exception to this is P1260, which will only clear following an ignition OFF/ON cycle after rectification).
7. 7. If the cause is not visually evident and the Jaguar approv ed diagnostic system is not available, use a fault code
reader to retrieve the fault codes be fore proceeding to the Diagnostic Trou ble Code (DTC) Index Chart, or the
Symptom Chart if no DTCs are set.
• NOTE: If the DTC flagged was not present for two or more co nsecutive cycles, it is classed as temporary, and will be
deleted following three cycl es during which no fault was present. This could result in a reported wa rning light/message with
no stored DTCs. If a fault is present for three consecutive cycles, the DTC becomes permanent, and will remain in the
module's memory for 40 drive cycl es (a cycle is an ignition OFF/ON, which will occur during the owner's normal use of the
vehicle. No action on the part of the technician is necessary to perform this cycle. A drive cycle is a series of conditions
needed to make the on-board diagnostic ro utine run, and may need a specific action on the part of the technician. See the
DTC summaries for drive cycle routines).
8. 8. Using the Jaguar approved diagnostic system where available, and a scan tool where not, check the freeze frame
data for information on the conditions applicable when the fault was flagged. The format of this will vary,
depending on the tool used, but can pr ovide information useful to the technician in diagnosing the fault.
