disconnected, a Radio Code Saver will allow sufficient current to pass to maintain the radio receiver/cassette player/mini disc
player and compact disc player memory, operate the clock and supply the door operated interior lights while isolating the
battery in the event of a short circuit.
Reconnecting the Battery
WARNING: If the battery has been on bench charge the cells may be giving off explosive hydrogen gas. Avoid creating
sparks, and if in doubt cover the vent plugs or covers with a damp cloth.
Always make sure that all electrical systems are switched OFF before reconnecting the battery to avoid causing sparks or
damage to sensitive electrical equipment.
Always reconnect the battery positive lead first and the negative last, ensuring that there is a good electrical contact and the
battery terminals are secure.
Restart the clock (where installed) and set it to the correct time.
Enter the radio receiver/cassette player/mini disc player and compact disc player keycodes and preset' frequencies, if known.
Following reconnection of the battery, the engine should be allowed to idle until it has reached normal operating temperature
as the stored idle and drive values contained within the ECM have been lost. Allow the vehicle to idle for a further three
minutes. Drive the vehicle at constant speeds of approximately 48 km/h (30 mph), 64 km/h (40 mph), 80 km/h (50 mph), 96
km/h (60 mph) and 112 km/h (70 mph) for three minutes each. This will allow the ECM to relearn idle and drive values, and
may cause driveability concerns if the procedure is not carried out.
Connecting a Slave Battery Using Jump Leads
WARNING: If the slave battery has recently been charged and is gassing, cover the vent plugs or covers with a damp
cloth to reduce the risk of explosion should arcing occur when connecting the jump leads.
CAUTIONS:
A discharged battery condition may have been caused by an electrical short circuit. If this condition exists there will be
an apparently live circuit on the vehicle even when all circuits are switched off. This can cause arcing when the jump leads are
connected.
Whilst it is not recommended that the vehicle is jump started, it is recognized that this may occasionally be the only
practical way to mobilize a vehicle. In such an instance the discharged battery must be recharged immediately after jump
starting to avoid permanent damage.
Always make sure that the jump leads are adequate for the task. Heavy duty cables must be used.
Always make sure that the slave battery is of the same voltage as the vehicle battery. The batteries must be connected
in parallel.
Always make sure that switchable electric circuits are switched off before connecting jump leads. This reduces the risk
of sparks occurring when the final connection is made.
WARNING: Make sure that the ends of the jump leads do not touch each other or ground against the vehicle body at any
time while the leads are attached to the battery. A fully charged battery, if shorted through jump leads, can discharge at a rate
well above 1000 amps causing violent arcing and very rapid heating of the jump leads and terminals, and can even cause the
battery to explode.
Always connect the jump leads in the following sequence.
Slave battery positive first then vehicle battery positive.
Slave battery negative next and then vehicle ground at least, 300 mm (12 in) from the battery terminal e.g. engine
lifting bracket. www.JagDocs.com

General Information - Road/Roller Testing
Description and Operation Published: 11-May-2011
Road or roller testing may be carried out for various reasons and a procedure detailing pre-test checks, through engine starting
and stopping, pre-driving checks, on-test checks to final checks on completion of the test is given in this section.
Unless complete vehicle performance is being checked, the full road test procedure need not be carried out. Instead, those
items particularly relevant to the system/s being checked can be extracted.
Pre - Test Checks
WARNING: If the brake system hydraulic fluid level is low, pedal travel is excessive or a hydraulic leak is found, do not
attempt to road test the vehicle until the reason for the low fluid level, excessive pedal travel or hydraulic leak is found and
rectified.
It is suggested that pre-test checks, and functional tests of those systems/circuits which affect the safe and legal operations
of the vehicle, such as brakes, lights and steering, should always be carried out before the road or roller test.
Engine oil level
Engine coolant level
Tires, for correct pressure, compatible types and tread patterns, and wear within limits
There is sufficient fuel in the tank to complete the test
All around the engine, transmission and under the vehicle for oil, coolant, hydraulic and fuel leaks. Make a note of any
apparent leaks and wipe off the surrounding areas to make it easier to identify the extent of the leak on completion of
the test
Starting the Engine
CAUTION: On initial drive away from cold and within the first 1.5 km (1 mile), do not depress accelerator pedal beyond
half travel until the vehicle has attained a minimum speed of 25 km/h (15 miles/h). Never operate at high engine speed or
with the accelerator pedal at full travel whilst the engine is cold.

Operation and Component Description
Description and Operation
System Operation
SERVICE INTERVAL INDICATOR - 3.0L V6 DIESEL, 5.0L V8 SUPERCHARGER AND 5.0L V8 NATURALLY ASPIRATED ENGINES ONLY
If the vehicle is within 3,200 kilometers (1,988 miles) of a service, the message center will display 'SERVICE REQUIRED IN
XXXX km or MILES'. The display reduces the 'service required in' readout by increments every 50 kilometers (30 miles). If this
distance drops below 1 km (0.6 miles), the message center will display 'SERVICE REQUIRED'.
These messages are displayed every time the vehicle enters power mode 6, for 4 seconds after the instrument cluster bulb
check routine has finished.
NOTE: The message center will display distance to next service in miles on an instrument cluster fitted with a Miles Per
Hour (MPH) speedometer unless the driver has changed the display units on the Touch Screen Display (TSD).
Reset Procedure
To re-set the service interval indicator, the following process switch presses must each be carried out within 3 seconds:
With the vehicle in power mode 0, (ignition off) press and hold the rear fog lamp switch
Allow the vehicle to enter power mode 6 (Press the start button without a foot on the brake)
Immediately release the rear fog lamp switch
Press and hold the trip computer cycle switch
Press and hold the rear fog lamp switch
Continue to hold the trip computer and rear fog lamp switches
If the process has been successful, the message center will display 'RESETTING SERVICE MODE' and then display
'SERVICE MODE RESET' after 10 seconds
Release both switches and return the vehicle ignition to off, power mode 0.
MESSAGE CENTER Component Description
The message center LCD (liquid crystal display) display has a viewable area of 126 pixels horizontal and 174 pixels vertical. It
is divided into six information display zones as follows, starting from the top:
Set speed
Transmission position
Warning /message display
JaguarDrive Optimization icon
Odometer/Trip computer information
Fuel level.
The message center is active at all times when the ignition is on and can also be active when the ignition is off, dependant on
the information to be displayed. The message center LCD illumination is controlled by the sun load light sensor located on the instrument panel. In bright conditions, the illumination is set to maximum brightness. As the ambient light levels drop, the
illumination dims. When the lights are switched on or activated by the 'AUTO' function, the illumination operates in the same
way until a defined ambient light threshold is reached, at this point the setting of the panel illumination dimmer in the
auxiliary light switch will control the brightness.
If more than one message is active, each message is displayed for 4 seconds in the order of priority. Once all messages have
been displayed, they are again displayed in turn for 2 seconds each. Warning messages can be displayed when the ignition is
in accessory power mode 4 which is the initial ignition state when a door is opened.
Message Priority
Messages are assigned priorities which are defined by the effect on driving safety and functional ability of the vehicle. When
new messages are displayed they may be accompanied by a chime from the instrument cluster sounder. A new message will be
displayed immediately, providing the currently displayed message (if there is one) has been displayed for at least 4 seconds. A
warning indicator will be activated simultaneously with the message being displayed. If more than one fault warning message
is being displayed, the messages will cycle, in priority order, with each message being displayed for 2 seconds.
INFORMATION DISPLAY
The transmission display is located in the upper section of the LCD. The transmission position information is sent from the TCM (transmission control module) in a high speed CAN (controller area network) message to the instrument cluster. The
transmission has three modes of operation:
Conventional automatic operation (JaguarDrive selector in 'D' position)
Sport automatic operation (JaguarDrive selector in 'S' position)
Manual gear operation - Jaguar Sequential Shift.

has detected water in the fuel system. Drain fuel filter to remove collected
water. Odometer Display
The odometer displays the total distance which the vehicle has traveled. This is calculated by the instrument cluster using
wheel speed signals from the ABS module.
The odometer can show 6 characters and distances up to 999,999 miles or kilometers. The total distance travelled is stored in a
EEPROM (electrically erasable programmable read only memory) and the RAM (random access memory). This ensures that the
total distance is not lost if the battery is disconnected.
The odometer value is passed to other vehicle system modules on the medium speed and high speed CAN bus. This is used to record the total vehicle mileage for diagnostic purposes and when storing DTC (diagnostic trouble code)'s.

module and fuel injector operating data from the ECM.
A 'Trip' button is located on the end of the LH (left-hand) multifunction switch and allows the driver to access, in sequence, the
available trip information by repeatedly pressing the button. The trip information is displayed in the following order:
Trip distance – The trip distance since the last reset is displayed
Average speed – The average speed since the last reset is displayed
Average fuel consumption – The average fuel consumption since the last reset is displayed
Range – The range is displayed showing the distance which can be travelled until the fuel gage reads empty. If the
range display shows dashes (-), this indicates a failure with one or both of the fuel level sensors.
The trip computer has three independent memories; A, B and Auto. Memories A and B can be set independently. The Auto
memory is reset after each ignition cycle and therefore only contains information relating the current journey.
The trip information can also be accessed from the TSD located in the center console. The TSD allows the same information
available with the trip button on the multifunction switch to be displayed on the TSD, with the addition of the option to reset
the values in the A and B memories.
If the battery is disconnected, all trip data in memories A, B and Auto are erased.
Fuel Level Display
The fuel level display is a linear LCD display to show the usable fuel tank contents. The level display is active at all times when the ignition is on. Low fuel level is displayed as a LOW FUEL LEVEL message and an amber warning triangle in the
message center.
The fuel level is obtained by fuel level sensors in the fuel tank. These are monitored by the RJB software and their output resistance values, corresponding fuel quantity, are transmitted to the instrument cluster on the medium speed CAN bus. The instrument cluster uses the two level sensor signals to calculate the fuel tank contents. This calculation takes into account
fuel movement in the tank to display a steady fuel quantity in the LCD.
The fuel level information is transmitted on the medium speed and high speed CAN bus for use by other vehicle system modules.
AUDIBLE WARNINGS
The instrument cluster can generate audible warnings to alert the driver to a displayed message and change of vehicle
operating condition. The audible warning is generated by a sounder located within the instrument cluster. The audible warnings
can be generated for the warnings below and are listed in order of priority, with the first being the highest priority:
Seatbelt reminder
EPB (High Pitch)
ACC Driver Intervene 1
Airbag fault
Key in ignition switch
ASL overspeed
ACC Driver Intervene 2
EPB (Low Pitch)
Vehicle armed (entry delay)
JaguarDrive selector not in park
Valet mode
Lights on reminder
Hood operation
Passive Entry / Passive Start (PEPS)
Memory set
Turn signal indicators
Seat Belt Minder.
The audible warnings can take the form of a single chime, a number of chimes or a continuous chime. The audible warnings are
initiated by a CAN message request from the requesting sub-system control module or by the instrument cluster software.
Page 2027 of 3039
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

15 Xenon igniter unit and bulb 16 Xenon igniter electrical connector 17 Cornering/static bending lamp bulb (if fitted) 18 Side lamp bulb 19 High beam headlamp bulb 20 Cover - Side lamp, cornering/static bending lamp (if fitted) and high beam headlamp bulbs 21 Electrical connector Bi-Xenon Headlamp
The bi-xenon headlamp uses a projector lens, similar to the halogen headlamp. The projector module comprises an ellipsoidal
lens and a reflector. The projector reflector collects the light produced by the halogen bulb and projects the light into a focal
plane containing a shield. The contour of the shield is projected onto the road by the lens. A complex surface reflector is used
for the halogen fill in high beam lamp. This type of reflector is divided into separate parabolic segments, with each segment
having a different focal length. The low and high beam bulbs are quartz halogen H7, with a rating of 55W. The bulbs are
retained in the headlamp unit with conventional wire retaining clips.
A tourist lever mechanism is located on the right hand side of the projector module. This mechanism moves a flap to blank off
a portion of the beam spread to enable the vehicle to be driven in opposite drive hand markets without applying blanking
decals to the headlamp lens. The beam is changed by removing the access cover at the rear of the lamp assembly and moving
a small lever located near the bulb holder, at the side of the projector.
NOTE: The tourist lever is not fitted to NAS vehicles.
WARNING: The Xenon system generates up to 30000 volts and contact with this voltage could lead to fatality. Make sure
that the headlamps are switched off before working on the system.
The following safety precautions must be adhered to when working on the xenon low beam headlamp system:
DO NOT attempt any procedures on the xenon headlamps when the lights are switched on.
Handling of the D1S xenon bulb must be performed using suitable protective equipment; for example gloves and
goggles. The glass part of the bulb must not be touched.
Xenon bulbs must be disposed of as hazardous waste.
Only operate the bulb in a mounted condition in the projector module installed in the headlamp.
The xenon headlamp is known as 'bi-xenon' because it operates as both a low and high beam headlamp unit. The xenon lamp,
or High Intensity Discharge (HID) lamp as they are sometimes referred to, comprises an ellipsoidal lens with a solenoid
controlled shutter to change the beam output from low to high beam.
NOTE: If the lighting control switch is in the 'off' position, both the xenon lamp and the halogen high beam lamp will
operate when the high beam 'flash' function is operated.
The xenon headlamp system is controlled by the CJB using a control module for each headlamp and an igniter. The control modules and the igniters provide the regulated power supply required to illuminate the bulbs through their start-up phases of
operation.
The xenon headlamp is a self contained unit located within the headlamp assembly. The unit comprises a reflector, an adaptor
ring, the lens, a shutter controller and the xenon bulb, which together forms an assembly known as the projector module. The
reflector is curved and provides the mounting point for the xenon bulb. The bulb locates in a keyway to ensure the correct
alignment in the reflector and is secured by a plastic mounting ring. The bulb is an integral component of the igniter and is
electrically connected by a connector located in the igniter unit.
The shutter controller is a solenoid which operates the shutter mechanism via a lever. The shutter is used to change the beam
projection from low beam to high beam and vice versa.
The xenon bulbs illuminate when an arc of electrical current is established between 2 electrodes within the bulb. The xenon
gas sealed in the bulb reacts to the electrical excitation and the heat generated by the current flow to produce the
characteristic blue/white light.
To operate at full efficiency, the xenon bulb goes through 3 full stages of operation before full output for continuous operation
is achieved. The 3 phases are; start-up phase, warm-up phase and continuous phase.
In the start-up phase, the bulb requires an initial high voltage starting pulse of up to 30000 volts to establish the arc. This is
produced by the igniter. The warm-up phase begins once the arc is established. The xenon control module regulates the supply
to the bulb to 2.6A which gives a lamp output of 75W. During this phase, the xenon gas begins to illuminate brightly and the
environment within the bulb stabilizes, ensuring a continual current flow between the electrodes. When the warm-up phase is
complete, the xenon control module changes to continuous phase. The supply voltage to the bulb is reduced and the operating
power required for continual operation is reduced to 35W. The process from start-up to continuous phase is completed in a very
short time.
The xenon control modules (one per headlamp) receive an operating voltage from the CJB when the headlamps are switched on. The modules regulate the power supply required through the phases of start-up.
The igniters (one per headlamp) generate the initial high voltage required to establish the arc. The igniters have integral coils
which generate high voltage pulses required for start-up. Once the xenon bulbs are operating, the igniters provide a closed
circuit for the regulated power supply from the control modules.
