systems.

A typical example of information transfer is vehicle speed information from the ABS (anti-lock brake system) module used to
control the automatic volume control function. The vehicle speed information from the ABS module is sent on the high speed
CAN network and collected by the instrument panel gateway. The signal is passed to the medium speed CAN network and onto the ICM gateway. The ICM calculates the volume adjustment required. The corrected audio volume level signal is sent on the
MOST network to the IAM or Power amplifier (dependant on vehicle equipment level) for output to the speaker system.

AUDIO SYSTEM USER CONTROLS

Touch-Screen



Item Description 1 Touch-screen 2 Home menu button 3 Touch-screen on/off button The Touch-screen forms the basis of the audio system. It communicates with the rest of the audio/infotainment system on the
MOST ring and allows control of the audio system and other infotainment systems from a single point.

The Touch-screen communicates with the IAM on the MOST ring and provides the primary user interface and display of the
audio system controls. No configuration procedure is required if the touch-screen is replaced.

Calibration of the Touch-screen using the Jaguar approved diagnostic equipment enables updates to be downloaded as new
technology becomes available or any fault concerns require software updates.
The touch-screen provides user control of the following systems:

System Functions Audio Radio display AM/FM or DAB, auxiliary and portable audio, digital TV or CD (compact disc) Climate
control Air conditioning, distribution, seats, heated steering wheel, automatic air recirculation Telephone Digit dialer, phone book, last ten calls (made, received, missed) Navigation Destination, stored locations, navigation setup, route options Vehicle
Security, parking, valet mode, trip computer, clock, brightness, contrast, system settings, vehicle settings, display settings

1 Volume adjustment 2 Change pre-set radio stations or CD tracks 3 Select audio source 4 Audio mute control/JaguarVoice control Additional control of the audio system is available in the form of steering wheel mounted switches which are located on the
left hand side of the steering wheel. The four switches provide for volume adjustment, change pre-set radio stations or CD tracks, select audio source and finally audio mute control. The mute control is also used for JaguarVoice control.

The steering wheel audio control switches are hardwired through the clock spring to the ICM. The ICM processes the analogue
signals from the switches into digital signals. The digital signals are then passed from the ICM onto the MOST system to
control the requested audio functions.

AVC (automatic volume control) controls the audio volume in relation to vehicle speed. As vehicle speed increases the audio
level is adjusted to compensate for extra road and vehicle noise. There are three settings for AVC:

Low
Medium
High
Setting of the AVC level is made using the audio controls. The default setting is medium.

The vehicle speed signal is used to enable the ICM to calculate the volume adjustment required. The vehicle speed signal is
received over the CAN. The signal is an average of the four wheel speed sensor signals. Should an invalid speed signal be received the AVC will not alter the output volume.



INTEGRATED AUDIO MODULE Component Description



The IAM is located in the center console behind the ICP faceplate, and combines the radio tuner and CD player. The head unit controls which of the two sources is routed to the speakers. All tuner versions have AM/FM reception. Each audio system
features auto-store, with a press and hold function to store selected channels as pre-sets. The standard search facility finds
the nine strongest channels currently available, while search and manual tuning allow channels to be stored as above.

The Jaguar Sound System IAM uses an internal amplifier which directly drives the system speakers. The Jaguar 320W Premium
Sound System and Bowers & Wilkins 440W Surround Sound System differs from the Jaguar Sound System with the addition of
an external amplifier. Audio output signals from the IAM are sent on the MOST system to the external amplifier which drives
the system speakers.

7 Triple TV antenna module 8 RF filter The diversity antenna module, located on the left hand side of the heated rear window, receives signals from four antennas
located in the heated rear window, where one antenna is dedicated as an AM antenna.

The diversity tuning system ensures that the strongest signals are used by the radio system to ensure the best possible FM
reception. Using the three remaining receiving antennas serves to eliminate multipath signal distortion. Typically, the signal
from the antenna with the least noise is chosen, and the other antennas are ignored.

The diversity antenna module is an interface between the antenna aerials in the heated rear window and audio system
modules/tuners. It provides antenna signals to the AM/FM tuner in the IAM, to the DAB receiver and to the VICS (vehicle
information and communication systems) or TMC (traffic message channel) in the navigation computer.

There are three different types of diversity antenna module fitted depending on the vehicle market and infotainment
equipment specification:
AM/FM with one co-axial output
AM/FM and VICS/TMC with two co-axial outputs
AM/FM, VICS/TMC and DAB band III with three co-axial outputs
The diversity antenna module receives a power supply from the IAM.

Vehicle or other component generated electromagnetic interference may cause unwanted disturbances in the radio and TV
reception signals. The disturbance may interrupt, obstruct, or otherwise degrade or limit the effective performance of the
circuit. It frequently affects the reception of AM radio in urban areas and can also affect FM radio and television reception,
although to a lesser extent.

The RF filters, which act as RF isolators, are located on both sides of the heated rear window and are used to reduce the
electromagnetic interference. The left hand side RF filter is connected across the heated rear window power supply and used to
separate the DC (direct current) interference from the RF signals. The right hand side RF filter is used in conjunction with the
TV antenna module (if fitted). If the TV system is not fitted the filter is linked directly to ground.

INFORMATION CONTROL MODULE



The ICM is located beneath the IAM in the center console. The unit performs a range of infotainment and some climate-control
functions.

The ICM, which is the timing master of the MOST system; supplies clock information to all other devices on the network which
synchronize their operation to this clock.

The unit also controls and manages the MOST ring and provides the allocations of channels, system power management,
functionality and co-ordination of the other system components.

The system becomes operational when the vehicle is unlocked and a 'wake up' signal is received by the ICM on the medium
speed CAN. The ICM 'wakes up' all the control modules on the MOST system ready for immediate operation by the vehicle user. If the ICM is replaced it must be configured as a new module using the Jaguar approved diagnostic equipment.

Calibration of the ICM using the Jaguar approved diagnostic equipment enables updates to be downloaded as new technology
becomes available or any fault concerns require software updates.

Authoring Template System Operation

INTRODUCTION TO THE GLOBAL POSITIONING SYSTEM

The system used to calculate the current position of the vehicle is called the GPS. The system utilizes satellites which are owned by the United States Department of Defense. A total of 24 satellites circular orbit the earth every 12 hours at a height
of 20,000 km (12500 miles), and between 5 and 11 of these satellites can be seen from a single point at any given time. The
orbits are tilted to the earth's equator by 55 degrees to ensure coverage of polar regions. Each satellite transmits radio signals
to provide information about the satellite position i.e. latitude, longitude, altitude, almanac data and an accurate time signal
generated by an on-board atomic clock. Each satellite contains four atomic clocks.
The vehicle needs to receive data from at least four different satellites to give a three dimensional fix on its current position.

As the vehicle moves, this information is continually being updated. The computer determines which satellites are 'visible' to
the system and their current position and relationship to each other. Using this information the computer can account for
positional deviations of the satellites and compensate to enhance the accuracy of the navigation system.

Steering Wheel Controls



Item Description 1 Volume adjustment 2 Scroll wheel (No navigation functionality) 3 Audio source (No navigation functionality) 4 JaguarVoice control Additional control of the navigation system is available in the form of steering wheel mounted switches which are located on
the left hand side of the steering wheel. 2 switches are used for navigation functions;

Volume adjustment
JaguarVoice control

JaguarVoice enables operation of several voice activated functions of the infotainment and climate control systems without the
need to touch any controls manually. The following systems include JaguarVoice functionality;

Navigation system
Phone system
Climate control system
Vehicle display system
Vehicle notepad

The 'notepad' facility allows voice notes to be recorded. Nametags for phone dialing and navigation locations allow the system
to be personalized and there is a help and tutorial function to provide advice on using the system.

The system allows the vehicle user to concentrate fully on driving the vehicle, without any need to divert their eyes from the
road ahead in order to check information read outs on the vehicle instrument panel information units. The voice control system
also feeds back audible information to the vehicle user.
JaguarVoice is a key component of the navigation system, allowing hands free control when issuing navigation commands.

The system is controlled by the voice button on the left hand side of the steering wheel. Voice commands are picked up by a
dedicated microphone. When giving a voice command audible feedback will be heard through the vehicle’s audio speakers.

by Field Effect Transistors (FET's). The FET's can detect overloads and short circuits and respond to heat generated by
increased current flow caused by a short circuit.

On a normal conventionally protected circuit this would cause a fuse to blow. The FET's respond to the heat increase and
disconnect the power supply to the affected circuit. When the fault is rectified or the FET has cooled, the FET will reset and
operate the circuit normally. If the fault persists the FET will cycle, disconnecting and reconnecting the power supply.

The CJB and the RJB store fault codes which can be retrieved using a Jaguar approved diagnostic system. The fault code will identify that there is a fault on a particular output circuit which will assist with fault diagnosis and detection.
Alarm Indications

The exterior lighting system is used for alarm arm and disarm requests to show alarm system status.

When the driver locks and arms the vehicle, a visual indication of a successful lock and arm request is displayed to the driver
by a single flash of the hazard flashers. If the vehicle is superlocked, then the hazard flashers will flash a second time (200 ms
off and 200 ms on) to confirm the superlock request.

If the alarm is activated, the hazard flashers are operated for 10, 30 second cycles of 200 ms on and 200 ms off, with a 10
second delay between each cycle.


NOTE: On North American Specification (NAS) vehicles, the delay between the cycle when the alarm is activated is 60
seconds.
Lights on Warning

When the ignition is in the off power mode 0 or accessory power mode 4 and the lighting control switch is in the side lamp or
headlamp position, a warning chime will sound if the driver's door is opened. This indicates to the driver that the exterior
lights have been left switched on.

The chime is generated from the instrument cluster sounder on receipt of a lights on signal, a driver's door open signal and an
ignition off power mode 0 or accessory power mode 4 signal via a medium speed CAN bus signal from the CJB. Headlamp Timer

The RJB controls the headlamp timer function which allows the headlamps to remain on for a period of time after leaving the vehicle. This is a driver convenience feature which illuminates the driveway after leaving the vehicle.

To operate the timer function the lighting control switch must be in one of the three headlamp timer positions when the
ignition status is changed from ignition on power mode 6 to the off power mode 0. The timer function will then be initiated and
the low beam headlamps will be illuminated for the selected timer period.


NOTE: If the lighting switch is in the AUTO position, the headlamp timer will not function when the ignition is changed to
off power mode 0.

When the lighting control switch is in the autolamp exit delay position, the lighting control switch reference voltage flows
through 4 of the resistors. The returned signal voltage is detected by the instrument cluster which outputs a message on the
medium speed CAN bus to the RJB that autolamps has been selected.
Depending on the selected exit delay position, the reference voltage to the autolamp exit delay switch is routed through 3, 2
or 1 resistors which is detected by the instrument cluster. The cluster outputs a message on the medium speed CAN bus to the RJB that autolamp exit delay period has been selected at 30, 60 or 120 seconds respectively. Crash Signal Activation

When a crash signal is transmitted from the RCM (restraints control module), the RJB activates the hazard flashers. The hazard flashers continue to operate until the ignition is in the off power mode 0 or accessory power mode 6. Once this ignition state
has occurred, the RCM will cease to transmit the crash signal.
LIGHTING CONTROL SWITCH

The instrument cluster outputs 2 reference voltages to the rotary lighting control switch; one feed being supplied to the light
selection function of the switch and the second feed being supplied to the auto headlamp exit delay function. The switch
position is determined by instrument cluster by the change in returned signal voltage which is routed through up to 4 resistors
in series depending on the selection made.

OFF - When the lighting control switch is in the off position, the reference voltage flows through 1 of the resistors. The
returned signal voltage is detected by the instrument cluster which outputs a message on the medium speed CAN bus to the CJB that no lighting selection is made. The reference voltage to the auto headlamp exit delay switch is routed through 4 resistors which is detected by the instrument cluster which outputs a message on the medium speed CAN bus to the CJB that auto headlamp or exit delay has not been selected.

SIDE LAMPS - When the lighting control switch is in the side lamp position, the reference voltage flows through 2 of the
resistors. The returned signal voltage is detected by the instrument cluster which outputs a message on the medium speed
CAN bus to the CJB to activate the side lamps. The reference voltage to the autolamp exit delay switch is routed through 4 resistors which is detected by the instrument cluster which outputs a message on the medium speed CAN bus to the CJB that auto headlamp or exit delay has not been selected.
HEADLAMPS - When the lighting control switch is in the headlamp position, the reference voltage flows through 3 of the

1 Headlamp leveling rotary thumbwheel (halogen headlamps only) 2 Instrument panel illumination dimmer thumbwheel 3 Luggage compartment lid release switch 4 Forward alert switch (if fitted) 5 Rear fog lamp switch The auxiliary lighting switch is located in the instrument panel, adjacent to the steering column. The switch has a rear fog
lamp switch and a rotary thumbwheel to adjust headlamp leveling on vehicles with halogen headlamps. The auxiliary lighting
switch also has a forward alert switch (if fitted) and a rotary thumbwheel for instrument panel illumination dimming.

The rear fog lamp switch is a non-latching switch which provides a momentary signal to the instrument cluster. The fog lamps
can only be activated if the ignition is in power mode 6 and the headlamp or auto headlamps are selected on. If the fog lamp
switch is pressed when the fog lamps are operating, they will be switched off. If the lighting control switch is moved to the
side lamp or off position or if the auto headlamps turns off the headlamps the rear fog lamps will be extinguished. If the
headlamps are subsequently turned on the rear fog lamp operation will not be active and the rear fog lamp switch must be
pressed to activate the lamps.

HEADLAMP ASSEMBLY

Two types of headlamp are available; xenon or halogen. The headlamp is secured in the front of the vehicle with three bolts;
one outboard bolt is screwed into the front upper cross member, one inboard bolt in the front upper body gusset and one bolt
located at the rear of the headlamp assembly which locates in the front fender reinforcing panel. Bulb replacement requires the
removal of the 3 bolts and the headlamp assembly.

The rear of the headlamp has removable panels which allow access to the bulbs for replacement. A large cover can be rotated
counter-clockwise for removal allows access the headlamp low beam halogen or xenon D1S bulb. Another large removable cover
can be rotated for removal to provide access to the high beam bulb, side lamp bulb and cornering/static bending lamp bulb (if
fitted).

The headlamps have 2 adjustment screws on the rear which allow for the manual setting of the vertical and horizontal
alignment.

On NAS vehicles, the headlamp is regarded as 'Visual Optically Left' aiming. The adjustment screws must be turned equal
amounts to maintain the correlation in the vertical axis only. There is no horizontal adjustment. Refer to the Service Repair
Procedures manual for headlamp alignment data and procedures.

Each headlamp has an integral 16 pin connector which provides inputs and outputs for the various functions of the headlamp
assembly. NOTE: RHD (right-hand drive) switch shown
