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.

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.

CELL BATTERY Verify surface charge removed. Disconnect battery from vehicle and re-test. If result repeats after
surface charge removal, replace battery. DO NOT RECHARGE. UNABLE TO DO TEST Disconnect battery from vehicle and re-test. 7 BATTERY CHARGING
It is essential that a suitably ventilated defined area exists in each dealership / retailer for battery charging.
CAUTION: It is very important that when charging batteries using the traction charger or other stand-alone chargers that
the charger is set for the correct type of battery before charging commences. If the wrong switch is selected the result would
be a battery that is not charged fully and / or overheating can occur. Follow the manufacturers operating instructions.
Batteries MUST BE tested and if necessary charged every 30 days and charged after 90 days irrespective of any test. It is
recommended that dealers / retailers always have fully charged batteries ready for use.
CAUTION: Do not charge AGM batteries with voltages over 14.8 Volts as this will damage the battery.
A designated controlled area must be allocated for scrap batteries and clearly controlled as such.
To bring a discharged but serviceable battery back to a fully charged condition proceed as follows:
Check and if necessary top-up the battery electrolyte level. (Flooded maintainable batteries only)
Charge the battery using a JLR approved charger as detailed in the approved equipment document following the
manufacturers operating instructions.
NOTE: When using the Midtronics Diagnostic Charger, automatic mode must always be used. After charging and analysis,
the charger may display ‘Top-Off Charging’, Hit STOP To End. Do not stop charging until the current falls to 5A or less,
otherwise the battery will not be fully charged.
Following charging, a post charge battery condition test must be carried out in accordance with the table shown in the
Determining Battery Condition section (Section 6) of this procedure.
NOTE: The Midtronics code from the tester must be recorded on the form.
Any actions must be carried out in accordance with the table shown in the Determining Battery Condition section (Section 6)
of this procedure. The details must be recorded on the New Vehicle Storage Form which is part of the new vehicle storage
document.
For additional information, refer to: New Vehicle Storage Form (100-11 Vehicle Transportation Aids and Vehicle Storage, Description and Operation).
8 BATTERY REPLACEMENT
If it is determined that a battery requires replacement, always refer to the appropriate section of the workshop manual for
instructions on removing and installing the battery from the vehicle.
On in service vehicles fitted with a Battery Monitoring System (BMS), the BMS control module must be reset following the
installation of a new battery. The BMS control module reset procedure must be performed using an approved diagnostic

Battery and Charging System - General Information - Quiescent Drain
Description and Operation
VEHICLE QUIESCENT CURRENT TESTING
On vehicles fitted with a Battery Monitoring System (BMS), the diagnostic routine for quiescent drain testing in the approved
Jaguar or Land Rover diagnostic system should be utilized.
If a customer complains of a vehicle battery that discharges continuously or when left for a prolonged period of time, it is
recommended that a quiescent drain test is performed as described below.
The battery drain should be measured using the approved Jaguar or Land Rover diagnostic system or a Digital Multi-Meter
(DVOM). A procedure for quiescent drain measurement using the diagnostic system is available in the Diagnosis and Testing
section of the Workshop Manual. The vehicle should be in the locked/armed state (for example vehicle alarm fully armed), all
doors, engine and luggage compartment lids are open and latched (so as to appear closed from an electrical point of view).
The test should take place after the vehicle has entered shutdown mode. The time taken for this to occur after the ignition is
switched off varies according to model (Refer to the Topix On line resource for details).
When the vehicle is armed, the effect of the security system Light Emitting Diode (LED) flashing is to cause a pulsation in the
measured current drain. In this case, either the average current should be taken (using a Digital Multi- Meter (DVOM) with an
averaging system) or the current reading taken, ignoring the brief high current peaks.
EQUIPMENT
Approved Jaguar or Land Rover diagnostic system with current probeOR Digital Multi-Meter (DVOM) with current probe.
METHOD OF MEASUREMENT
Using an Approved Jaguar or Land Rover Diagnostic System.
1. Switch off all electrical loads and ensure that the ignition is off
2. Connect the current probe to the approved Jaguar or Land Rover diagnostic system
3. Calibrate the probe
4. Install a clamp around the battery lead/junction box lead
5. Go to the Quiescent Current Testing section in this procedure
Using a digital multimeter
Do not use an in-line DVOM to measure the quiescent drain on vehicles fitted with an electronic throttle (for example XK 2006
onwards). The current exceeds the maximum amount the fuse in the DVOM is capable of handling.
1. Switch off all electrical loads and ensure that the ignition is off
2. Connect the current probe to the digital multmeter
3. Calibrate the probe
4. Install a clamp around the battery lead/junction box lead
5. Go to the Quiescent Current Testing section in this procedure
QUIESCENT CURRENT TESTING
1. Switch ignition to ‘on’ or select ignition mode in keyless vehicles and switch to ‘off’ (do not crank)
2. Remove key from ignition switch (if equipped)
3. Open and latch all doors, hood and luggage compartment lid
4. Lock the vehicle using the remote function on the remote handset. (Single lock only to avoid volumetric alarm arming)
5. Remove any other potential electrical drains such as accessories plugged into accessory sockets
6. Record the amperage readings after the shutdown period referenced in the Topix on line resource for details. Note all
cars from 10MY onwards and XK from 07MY and XF from 08MY should be less than 30mA after 30 minutes
7. Record the final reading on the battery report form
The preferred method of testing following an excessive current consumption figure is to use a current probe around individual
junction box leads to the various suspected circuits to identify a potential cause. This is in preference to the old method of
removing fuses for the following reasons:
The drain may be caused by a module remaining active and preventing the quiescent drain from reducing to normal
levels
The drain may be caused by a relay winding that is activated. Pulling the fuse can allow this to ‘reset’ and the drain will
be lost and go un-diagnosed
QUIESCENT DRAIN - TYPICAL VALUES
NOTE: The quiescent drain after the initial shutdown period should not exceed the value shown in the table.
