Windshield Wipers and Washers
The windshield wiper linkages and motor are a
combined unit with the operating logic integrated
into the GECM. The wiper system has two wiper
arms/blades which are handed for LHD or RHD.
Wipers are twin speed with variable six speed
intermittent operation and, optionally, moisture
sensitive operation.
Wiper arms do not lock away from the glass, they
must be held away from the windshield when
cleaning the glass. A special tool (501065) is
required to remove the wiper arms from the body.
Windshield washer jets are hood mounted. Two
sizes of washer reservoir are available, one for
windshield wash only, 4.4 litres, and one for
windshield wash and headlamp power wash,
6.6 litres. The reservoir is mounted forward of the
RH front wheel.
Headlamp power wash jets extend by water
pressure and retract by spring pressure.
A spoiler is fitted to the driverÕs wiper blade for
UK and European markets only.

FRONT SEAT BELT PRE-TENSIONERFront Seatbelts and Pre-tensioners
The front seatbelts are of the inertia reel type with
integral pre-tensioners and torsion bar load
limiters fitted to the reel assemblies. The lower
anchorage and buckle strap are mounted on the
moving seat slides to maintain optimum belt
geometry. The shoulder anchorage is fixed to the B
post via a four position height adjuster. An
automatic locking retractor (ALR) is incorporated
in the passenger belt reel assembly to provide
child seat security.
A compact type of pre-tensioner is fitted to the
front seatbelt reel assemblies. The reduced size is
achieved by the use of rack and pinion gearing to
retract the seatbelt reel when the unit is fired.
The initiator is a conventional pyrotechnic device
which is electrically triggered from the Restraints
Control Module (RCM).
Fault diagnosis of the pre-tensioner firing circuits
is carried out by the RCM and the presence of a
fault is indicated by the airbag warning lamp (see
Diagnostics).
The pre-tensioner is an integral part of the seatbelt
assembly and is not serviceable. Normal safety
procedures applicable to the handling of
pyrotechnic devices must be followed.
Note that plastic belt guides are fitted to the B
posts: if the pre-tensioners are fired, these guides
will fracture.
Rear Seatbelts
All three rear seatbelts are of the inertia reel type
with child seat automatic locking retractors.
The two outboard retractor assemblies are
mounted on the rear quarter panels. The centre
retractor is reverse wound and mounted in a
recess on the rear parcel shelf.

Control and Operation
The speed of the fuel pump is varied under closed
loop control so as to deliver the required fuel rail
injection pressure in accordance with factors such
as driver demand, manifold pressure and
temperature changes. The control loop sensors,
providing feedback information to the powertrain
control module (PCM), are the engine fuel
temperature (EFT) sensor and the injection
pressure (IP) sensor which are both mounted
directly on the engine fuel rail (see
S-TYPE Powertrain Technical Guide). The IP sensor
also has a vacuum feed from the intake manifold
so as to measure the pressure differential.
The required fuel flow is determined by the PCM
and sent to the rear electronic control module
(RECM) which is the power driver for the fuel
pump. The PCM demand to the RECM is a pulse
width modulated (PWM) signal over a single line
at a frequency of approximately 256 Hz and a
duty cycle of 0-50%. The RECM effecively
amplifies this signal by increasing the frequency
by 64 and doubling the duty cycle, thus providing
the necessary high current drive for the fuel
pump. The fuel pump relay, located in the rear
power distribution box, is energised by the PCM
relay and provides a dedicated fused supply to the
RECM for the pump drive.
When the ignition switch is turned from OFF to
RUN or START, the PCM primes the system by
running the pump for 1 second at full speed. The
pump is switched off 1 second after the engine is
stopped. During hot starts, fuel pressure is
increased to prevent vapour lock.
Fuel pump drive status is monitored by the RECM
and communicated to the PCM via the SCP
network.
Outputs from the fuel senders are connected by
independent wires to the RECM which sends the
data to the instrument pack and the PCM.
Inertia Switch
The inertia switch is located behind the trim on
the left side of the vehicle, forward of the front
door post and below the fascia. A finger access
hole in the trim allows the switch to be reset.

Introduction
The automatic and manual transmission units are
described in the ÔS-TYPE Sports Sedan Powertrain
IntroductionÕ Technical Guide.
J-Gate
The J-gate assembly is mounted on the
transmission tunnel by four bolts and has a
similar operating mechanism to the XJ/XK Series
vehicles. The selector gate positions are, P-R-N-D
on one side of the ÔJÕ and manual gear positions
4-3-2 on the other side. Movement of the gear
selector lever up and down these positions is
transmitted mechanically to a cable assembly
which then rotates the digital range switch on the
side of the automatic transmission housing (see
ÔS-TYPE Powertrain IntroductionÕ Technical
Guide). Movement across the gate between D and
4 operates an electrical switch (without cable
movement).
In the P position with the ignition off, the gear
selector lever is locked by a solenoid plunger
which inhibits a lock plate fixed to the selector
mechanism. When the ignition is switched on,pressing the brake pedal energises the solenoid
and releases the lock plate, allowing the selector
lever to be moved from the P position.
For NAS markets only, the J-gate slider actuator is
linked to the ignition switch barrel to provide a
mechanical interlock. The interlock lever and
cable are driven by the J-gate slider to operate a
locking plunger in the ignition barrel. If the gear
selector lever is in any position other than P, the
ignition key cannot be removed. Note when
servicing, that the interlock cable adjustment is
critical and the JTIS service instructions must be
followed. Where the interlock function is not
fitted, the interlock lever is retained without the
operating cable.

Driveline
Introduction
The driveline is a standard type with the engine
position at the front and driven rear axle. This will
be the first time that Jaguar has used in-plant
driveline balancing to improve noise, vibration
and handling. The driveline is finely balanced at
the rear driveshaft joint. The centre bearing is
laser aligned during initial factory build.
The alloy rear engine mountings have two
variants, one for automatic transmission and one
for manual transmission. They are both
serviceable items. The V6 auto is the same as the
V8 but rotated in plan by 180 degrees. The rubber
mountings are carry over concept from the
current XJ and XK Series vehicles but are not
D.307.322
DRIVELINE ARRANGEMENTinterchangeable with them. Both automatic
transmission rubber mountings are common but
with a softer unique mount for the manual V6
transmission.
In service if they are replaced, ensure that there
are buffer gaps and that they are approximately
equal. Neither will be contaminated by lubricant
or automatic transmission fluid.
Driveshaft
The S-TYPE has a two-piece welded steel tube
driveshaft with a splined centre slip joint and
locking collar, the whole being aligned with the
body centreline. The driveshaft has rubber flex
couplings and a rubber, body-mounted, centre
bearing. For safety, the front tube is collapsible.

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
