BRAKE BOOSTER Brake Booster
The brake booster is a Lucas unit mounted on the
engine bay bulkhead with a 25.4mm diameter
master cylinder and integral brake fluid reservoir.
NOTE: The reservoir is also a combined
brake/clutch reservoir for manual transmission
vehicles.
Twin vacuum boosters of 8 inch and 9 inch sizes
are fitted.
The DSC booster is different having integral
pressure transducers and solenoids with air
control valves for the booster. The transducers are
located on the brake master cylinder and are used
for pressure feedback, brake application and fail
safe operation. The booster is used to supply
brake pressure without driver input.
ABS operation is no different to current Jaguar
vehicles.
Parking Brake
The parking brake lever is mounted on the RH
side of the centre console for all models, with
conventional button operation as current XJ
sedan. It is a self-adjusting system operating on
the rear brake callipers. All models have a leather
grip.

Serial Data Link The multiplexed electrical architecture is used for
the exchange of information between control
modules, the instrument pack and the data link
connector.
Multiplexing allows more than one piece of
information to be carried along a wire. In this
way, the electronic control modules can
communicate with each other quickly and share
information. With multiplexing, just two
intertwined wires carry information to any control
module on the network. On the SCP system
hundreds of messages a second can be
transmitted; the maximum waiting time is only a
few hundred milliseconds. An additional benefit is
that the modules ÔsleepÕ when not in use,
reducing battery drain.Principles of Operation
The vehicle has two module communication
networks. The first is the Standard Corporate
Protocol (SCP - J1850 SAE standard)), which is an
unshielded twisted pair cable: data bus plus and
data bus minus. The second is the International
Standard Organization (ISO) 9141 communication
network, which is a single wire network. Both
networks can be connected to the PDU tester by
one connector: the data link connector. The data
link connector is located under the instrument
panel, between the steering column and the audio
unit.
The ISO 9141 communications network does not
permit inter-module communications. When the
PDU tester communicates to modules on the ISO
9141 communication network , the PDU must ask
for all information; the modules initiate
communications.

74The SCP communication network will remain
operational even with severing of one of the bus
wires. Communications will also continue if one
of the bus wires is shorted to ground or battery
positive voltage (B+), or if some , but not all,
termination resistors are lost.
Unlike the SCP communication network, the
ISO 9141 communication network will not
function if the wire is shorted to ground or battery
positive voltage (B+). Also, if one of the modules
on the ISO 9141 network loses power or shorts
internally, communication to that module will fail.
Control Modules
The vehicle control module functions are
described briefly below (for further information
refer to the relevant sections throughout the
Guide).
Anti Lock Brake/Traction Control and
Dynamic Stability Control, Control Modules
The anti-lock brake control module is connected
to the SCP communication network. The module
comes in two forms. The first type is the standard
equipped anti-lock brake system (ABS) with
traction control (TC). It controls the brake
pressure to the four wheels to keep the vehicle
under control while braking.
The second type of ABS is optional and is called
dynamic stability control (DSC). This control
module adds yaw sensors to the package to help
in sensing a loss of vehicle control.
Audio Control Unit
The audio control unit is connected to the SCP
communication network and also to the audio
control protocol (ACP) communication network.
The audio control unit communicates with the
compact disc and the cellular phone transceiver.
Driver Door Control Module (DDCM)
DDCM is connected to the SCP communication
network. The module controls many functions
including power windows, driver mirror, power
locks, and keyless remote entry.Driver Seat Control Module (DSCM)
The DSCM is connected to the SCP
communication network. The DSCM is located
under the driver seat and controls the seat
positions. The module also communicates with the
DDCM to control the driver seat memory
functions.

Instrument Pack
Vehicle instrumentation is installed on the
instrument pack on the fascia. The calibration of
the odometer and speedometer, the language of
the message center and the composition of the
indicator lamps are tailored to suit the destination
market. The instrument pack acts as a system
monitor for the audible and visual warnings.When the ignition switch is turned to position II,
the following visual warnings (telltales) are
illuminated for three seconds to provide a bulb
prove out function:
¥ ABS telltale
¥ Airbag telltale (six seconds prove out)
¥ Catalyst over temperature telltale (Japan only)
¥ Charging system telltale

center stack. The Navigation Control Unit/CD Map
Loader is mounted in the rear LH side of the trunk
and covered by a dedicated styled trim panel (see
illustration on page 123). The GPS antenna is
located above the rear parcel shelf but hidden
underneath the interior trim.
Digital map information is held on a compact disk
(CD) which is loaded into the Navigation Control
Unit housed in the trunk.
The LCD provides full information for operating
the system by means of menus, text prompts and
map displays. Screen selections are made by the
controls on the front panel.
How the System Works
The system uses signals from the Global
Positioning system (GPS) satellites, which enables
the Navigation ECU to calculate, with the aid of
CD ROM map data, ABS sensorsÕ signals and Gyro
sensorÕs signals, the exact position of the vehicle
to within meters. After entering the desired
destination, the driver is guided along by both
voice and visual instructions. If the driver strays
off the route, the system calculates a new route
showing the easiest way back to the original
destination.
Voice Guidance
A chime and an audible instruction will be heard
just before the vehicle reaches the next junction
along the route where a turn has to be made.
Screen Guidance
The screen shows the map display with the
current vehicle position and route highlighted.
Just before each turn, the screen automatically
shows the next junction diagram (with turn
information) overlayed on the map display. After
the junction, the screen returns to full map
display.
Interfaces
The system also provides interfaces such as a TV
(Japan only), Vehicle Emergency message system
known as Jaguar ASSIST (North America only) and
Real Time Traffic Information (limited to certain
markets).
TV (Japan only)
The TV is a Dealer fit item and is displayed on the
Navigation screen. The sound is generated through
the vehicleÕs audio system in mono only. TV
