Engine Compartment
The engine compartment layout is common for both V6 and V8 engines. The front power distribution
box (fusebox) is located in the engine compartment.

INERTIA SWITCH operating fuel level sender assembly mounted on
the respective module assembly.
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.

Power Distribution
Distribution cables supply battery power through
to the starter motor and to three power
distribution/fuse boxes. Harnesses distribute
battery, auxiliary and ignition power from the fuse
boxes to all the user components. The front
power distribution/fusebox clean power is fed via
a clean power 175 ampere fuse (megafuse) which
is located next to the rear power distribution
box/fusebox.
The secondary junction box is located on the
bulkhead in the LH side of the cabin near the ÔAÕ
post. It acts as a splice header to avoid having
numerous splices in the harness.

Power Distribution Cables
Heavy duty power distribution cables connect the
battery to the body and to the engine starter and
the vehicle fuse boxes. The distribution cable from
the clean power fuse to the front fusebox is
routed on the LH side of the vehicle and along
part of the main body wiring harness.
Harnesses
The vehicle harnesses plug directly into
components or component flying leads using
locking connectors. The main harness layout is
shown in the illustration on the following page.

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.

The passenger compartment fusebox is located on
the right-hand side trim panel in the footwell.
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.
Luggage Compartment Fusebox
A fusebox is located in the luggage compartment,
situated forward of the battery.
Fold the luggage compartment floor panel to gain
access to the fusebox.
Remove the fusebox lid by pulling the retaining
clips and pulling the lid upwards.
Reposition the lid and press down until the
retaining clips engage.
