Front and Centre Floor Pan
The floor pan is a three-piece construction with
handed dash panels, welded front suspension
housing, an integral centre bearing panel for the
driveshaft and a large under-tunnel heatshield.
Rear Floor Pan
Multi-piece floor pan design, the rear tub is
designed to accept either a full size or space saver
spare wheel and the luggage compartment has
four tie-down luggage loops. Two plastic covers
are located under the rear seat and these give
easy access to the fuel tank mounted components.
A plastic battery tray is located below the luggage
load floor.
Roof
Provision has been made for roof rack fixings and
the roof has reinforcement for vehicles fitted with
a the sliding roof.
Sliding Roof
The sliding roof has an exterior encapsulated glass
roof panel, with sliding sunshade, and has tilt and
slide operation. The sunshade is available in two
colours to match the headlining. Note that the
sunshade cannot be closed if the sliding roof is in
the fully open position or has been partly closed
from the fully open position; this is because the
J.501.1775
SLIDING ROOF MOTOR ASSEMBLYpull-cup is hidden. To allow access to the
sunshade pull-cup, the sliding roof must be fully
closed. Special screws are used in some locations.
When replacements are required these screws are
supplied in packs, do not use any other screws
than those supplied. Low battery voltage may
prevent operation of the sliding roof although the
relays may be heard operating. The sliding roof
cannot be fitted as a retrofit item.
Body Side and Quarter
The vehicle has one piece body sides and one
piece door opening panels, with full height ÔAÕ
post and ÔB-CÕ post reinforcement. The jacking
reinforcement joins the door opening panel to
rear quarter inner reinforcement panel. Large
vacuum-formed wheel arch liners are fitted front
and rear. A sill appliquŽ protects the BIW
sheetmetal from stone damage and an anti-chip
coating is applied to the sills
Closures
One piece door inner and outer pressing with side
impact beams. One piece front and rear door
hinge reinforcement panels.
Door sealing is a triple seal system:
¥ primary seals - single sponge profile with part
dense rubber foot, ÔCÕ-channel mounted on
the upper door and peg mounted below the
waist.
¥ secondary seals - body side flange mounted
carrier with sponge and dense rubber,
colour-keyed trim flap
¥ margin sealing - flange mounted roof
rail/gutter seal which closes off the upper
door opening line above the waist and
terminates with a shaped moulding at each
end.
A variety of different profiles are peg mounted to
the ÔAÕ and ÔCÕ pillar periphery below the waist
and also door bottoms. A separate ÔBÕ pillar seal is
riveted as part of the ÔBÕ pillar appliquŽ.

INERTIA SWITCH operating fuel level sender assembly mounted on

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.

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.

Transit Relay
The purpose of the Transit Relay is to prevent the
battery from being discharged during transit and
Dealer storage. It automatically isolates the
battery following ignition off.
The transit relay is installed on the Negative line
through a spur from the trunk lighting harness
and is located on the battery Negative post.
If the vehicle is to be handed over to a customer
within a period of 24 hours of completion of the
PDI, the Transit Relay MUST be removed.
If the vehicle is NOT to be handed over to a
customer within a period of 24 hours of
completion of the PDI, a Transit Relay Test Lead
must be fitted to allow the PDI to proceed.
Under no circumstances should any means other
than the test lead be used to bridge the Transit
Relay.
The Transit Relay Test Lead MUST be removed
after the completion of the PDI and stored for
further use. Under no circumstances should the
vehicle be transported with the Transit Relay Test
Lead fitted.
The procedure to fit the Transit Relay Test Lead
and remove the Transit Relay is given in the PDI
Manual.
