Front Suspension
The independent front wheel suspension is a
double wishbone axle arrangement with
aluminium control arms. The two arms are of
different lengths, which minimises the changes in
track and camber. Inclination of the upper control
arm axis provides anti-dive front suspension
action. There are two front cross members,
known as Number 1 and Number 2.
Number 1, the forward cross member, is a steel
fabrication, non-isolated, which locates the lower
control arm front mounting, the anti-roll bar and
the cooling module.
The rear cross member, Number 2, is an
aluminium casting, non-isolated and it locates the
lower control arm rear mounting, the power
steering rack and the engine hydro-mounts.
WARNING: No attempt must be made to
weld or repair the aluminium cross
member. If it is damaged, a new one must
be installed.
Lower Control Arm
The lower control arm is an aluminium forging
and has locations for the damper and the anti-roll
bar drop link. It is mounted with one hydro-bush,
the front lower bush, and one rubber bush, both
serviceable. This is the first time that a hydraulic
bush has been fitted to a Jaguar wishbone. The
hydro-bush is tuned for refinement and helps to
J.204.402
reduce brake vibration.
Service adjustments for caster and camber can be
made to the lower control arm geometry with the
addition of cam bolts (not supplied with the
vehicle).

Brakes
Brake Control Module
Brakes are controlled with a Teeves Mk 20E brake
modulator.
The anti-lock brake/traction control, control
module (ABS/TCCM) contains the integral software
for ABS and traction control, similar to current XJ
and XK Series vehicles. It is supplied as a 10 valve,
4-channel module and calibration is the same to
all powertrains. It is connected to the SCP bus for
traction control, warnings and vehicle speed.
Dynamic Stability Control
Dynamic stability control (DSC) is a new Jaguar
safety feature, which uses ABS and traction
control to control yaw movements of the vehicle.
Yaw is the rotary motion of the vehicle on its
vertical axis, a force that would cause oversteer or
oversteer or sideslip. The dynamic stability
control module (DSCM) contains the same
software as described but with the addition of IVD
software. The modulator is supplied as a 12 valve,
4-channel module calibrated for base suspension
only. The connectors differ between the two; the
10 valve unit has a 25-way with sliding cam, as

76Air Conditioning Control Module (A/CCM)
The A/CCM is connected to the SCP
communication network. The A/CCM controls
automatic climate functions that maintain the
vehicle at a constant temperature setting.
Instrument Pack
The instrument pack is connected to the SCP
communication network. The instrument pack
displays information received on the SCP
including speedometer, odometer, fuel, and
message center warnings. The instrument pack
also controls the passive anti-theft system (PATS).
General Electronic Control Module (GECM)
The GECM is connected to the SCP
communication network. This module is located
behind the LH ÔAÕ post trim panel below the
fascia. The GECM controls many of the bodysystems, being directly linked to the interior
lighting, wiper and security systems. It is a support
module for other systems including exterior
lighting, locking, remote entry, mirrors
(passenger), seat/mirror/steering column memory
recall and windows.
Rear Electronic Control Module (RECM)
The RECM is connected to the SCP
communication network. This module is located in
the passenger side luggage compartment behind
the trim panel. The RECM controls the
locking/unlocking of the front passenger and rear
doors and provides power control of the fuel
pump.
Powertrain Control Module (PCM)
The PCM is connected to the SCP communication
network. For the location of this module see the S-
TYPE Powertrain Technical Guide The PCM
controls the engine performance, electronic
ignition, emission controls, speed control,
transmission and on board diagnostics.
Steering Column Lock Module (SCLM)
The SCLM is connected to the SCP communication
network. The module is an integrated unit
containing the steering column lock and lock drive
and is controlled remotely from the separate
ignition barrel.
Restraints Control Module (RCM)
The RCM is connected to the ISO 9141
communication network. The RCM controls the
deployment of the air bags based on sensor
inputs.
Vehicle Emergency Control Module (VECM)
The VECM is connected to the SCP
communication network. The module allows a
user to request emergency assistance (police,
ambulance, fire, wrecker) or directions to a
desired location at the touch of a button. Also, if
any of the vehicleÕs airbags are deployed while the
VEMS system is powered ON, the system
automatically issues a call for emergency
assistance.
Voice Activation Control Module (VACM)
The VACM is connected to the SCP
communication network. This module is located in
the driver side luggage compartment behind the
trim panel. The VACM controls and processes all

Fuses and Relays
Fuses
Fuse failure is identified by an inoperative circuit.
Two types of fuses are fitted in the fuseboxes, a
mini-type and a cartridge-type.
A special tool for removing and replacing the
mini-fuse is provided in the passenger
compartment fusebox, together with spare fuses.
If a spare fuse is used, replace it with a Jaguar
approved fuse of the same amperage rating.
Checking and Renewing a Blown Fuse
Make sure the new fuse is the correct rating
(amperage). Fuses are colour coded according to
the amperage and the rating is also marked on
each fuse.
WARNING:
Do not fit a fuse of a different amperage from
that removed. The electrical circuits may
become overloaded with the subsequent
possibility of a fire.
No attempt should be made to repair a fuse
that has blown. This may cause a fire hazard
or serious damage elsewhere in the
electrical circuit.
Fuse Boxes
There are three separate fuse boxes fitted to the
vehicle, each one containing fuses protecting a
different group of circuits.
They are located in:
¥ The engine compartment
(front power distribution box/fusebox)
¥ The passenger compartment
(primary junction box/fusebox)
¥ The luggage compartment
(rear power distribution box/fusebox)
Engine Compartment Fusebox
The fusebox is located in the engine compartment
on the RH side adjacent to the windshield wash
reservoir.
Caution:
When a fusebox lid is removed, take care to
protect the box from moisture, and refit the lid at
the earliest opportunity.
Remove the fusebox lid by pressing the retaining
lugs and lifting.
When refitting, press the fusebox lid in the area of
the retaining lugs until the lid engages.

section. A map/reading/courtesy lamp is fitted
above each rear passenger grab handle.
Illuminated Entry/Exit
When the vehicle is unlocked, the courtesy lamps
will gradually illuminate and remain on for 20
seconds.
If the courtesy lamps are on they will fade off
when the vehicle is locked with a key or a key-ring
transmitter.
