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.

procedure.
NOTE: Under no circumstances should the battery be disconnected with the engine running because under these
conditions the generator can give a very high output voltage. This high transient voltage will damage the electronic
components in the vehicle. Loose or incomplete battery connections may also cause high transient voltage.
3. HEALTH AND SAFETY PRECAUTIONS
WARNINGS:
BATTERY CELLS CONTAIN SULPHURIC ACID AND EXPLOSIVE MIXTURES OF HYDROGEN AND OXYGEN GASES. IT IS
THEREFORE ESSENTIAL THAT THE FOLLOWING SAFETY PRECAUTIONS ARE OBSERVED.
Batteries emit highly explosive hydrogen at all times, particularly during charging. To prevent any potential form of
ignition occurring when working in the vicinity of a battery:
Do not smoke when working near batteries.
Avoid sparks, short circuits or other sources of ignition in the battery vicinity.
Switch off current before making or breaking electrical connections.
Ensure battery charging area is well ventilated.
Ensure the charger is switched off when: a) connecting to a battery; b) disconnecting from the battery.
Always disconnect the ground cable from the battery terminal first and reconnect it last.
Batteries contain poisonous and highly corrosive acid. To prevent personal injury, or damage to clothing or the vehicle,
the following working practices should be followed when topping up, checking electrolyte specific gravity, removal, refitting or
carrying batteries:
Always wear suitable protective clothing (an apron or similar), safety glasses, a face mask and suitable gloves.
If acid is spilled or splashed onto clothing or the body, it must be neutralized immediately and then rinsed with clean
water. A solution of baking soda or household ammonia and water may be used as a neutralizer.
In the event of contact with the skin, drench the affected area with water. In the case of contact with the eyes, bathe
the affected area with cool clean water for approximately 15 minutes and seek urgent medical attention.
If battery acid is spilled or splashed on any surface of a vehicle, it should be neutralized and rinsed with clean water.
Heat is generated when acid is mixed with water. If it becomes necessary to prepare electrolyte of a desired specific
gravity, SLOWLY pour the concentrated acid into water (not water into acid), adding small amounts of acid while
stirring. Allow the electrolyte to cool if noticeable heat develops. With the exception of lead or lead-lined containers,
always use non-metallic receptacles or funnels. Do not store acid in excessively warm locations or in direct sunlight.
Due to their hazardous contents, the disposal of batteries is strictly controlled. When a battery is scrapped, ensure it is
disposed of safely, complying with local environmental regulations. If in doubt, contact your local authority for advice on
disposal facilities.

is operated to crank the engine. The GWM is connected to the ABS (Anti-lock Brake System) control module via the high speed
CAN bus. With the vehicle stationary and the engine off after an ECO engine stop, when the driver releases the brake pedal
the ABS control module senses the reduction in brake pressure. This change of brake pressure state is sent as a high speed
CAN message which is received by the GWM and the ECM. The GWM reacts within 105ms to instruct the DBM via the LIN bus
to operate the two contactors in the DBJB to supply the sensitive loads from the secondary battery and supply the TSS motor
direct from the primary battery.
When the engine is running and the generator is supplying power to the vehicle systems, the GWM again instructs the DBM to
operate the two contactors in the DBJB to supply all vehicle systems from the primary battery and the generator and to isolate
the secondary battery.
Secondary Battery Charging
The DBM also controls the charging of the secondary battery. The GWM contains electrical load management software and
monitors both batteries for their state of charge. The primary battery is monitored by the BMS control module which is
connected to the DBM via the LIN bus. The DBM communicates the primary battery condition to the GWM via a LIN bus
connection. The GWM sends a signal to the DBM via the LIN bus to instruct it to apply charging from the generator to the
secondary battery when required. The contactor 2 is closed by the DBJB to complete the secondary battery circuit, and the
generator output is applied to the secondary battery to charge it.
The generator output is controlled by the GWM which monitors and controls the electrical load management system. The
generator is connected to the GWM by a LIN bus allowing the GWM to control the output of the generator to maintain electrical
system load requirements and battery charging.
Electrical Load Management
The electrical load management is controlled by the GWM and the BMS control module.
The GWM will monitor the vehicle system power loads before and during an ECO engine stop.
Before an ECO engine stop, the GWM will transmit a signal to system control modules on the CAN bus to request a power save
on all electrical loads and set a minimum electrical value override. The GWM monitors the vehicle electrical loads and will
inhibit a ECO engine stop until the load current is at a value low enough to be supported by the secondary battery.
If the electrical loads cannot be reduced sufficiently, the GWM will inhibit the ECO engine stop.
When the engine is stopped after an ECO engine stop, the GWM will continue to monitor the primary battery state of charge.
If the primary or secondary battery voltage falls below 11.0V, a level which will result in degraded starting performance or
possible primary battery damage, the GWM will initiate an engine start.
System Inhibits
The ECO stop/start system is inhibited if the dual battery system is not be capable of preventing electrical loads on the
vehicle being subject to unacceptably low voltage levels during ECO stop/start operations due to a fault.
ECO stop/start inhibit monitoring of the primary battery is performed by the BMS control module. If the primary battery voltage
is too low to support an ECO stop/start, then the BMS control module will send a message to the GWM on the LIN bus to
suspend ECO stop/start.
The GWM monitors the secondary battery and the dual battery system components. Any fault found will cause the GWM to
inhibit ECO stop/start and the GWM will record a DTC (diagnostic trouble code).
Fault Diagnosis
The GWM performs passive and active diagnostics on the dual battery system to determine the status of the system
components.
Passive diagnostics can detect faults in the DBJB and can check for stuck open or closed contactors and failure of DBM
contactor command signals.
Active diagnostics is a routine to test the capability of the contactors to respond to open or close command signals sent from
the GWM to the DBM. This routine also checks the FET's (Field Effect Transistors) activate as required. (Refer to Dual Battery
Junction Box below for description of FET operation)
The GWM will also check the dual battery system components for faults in a controlled environment when the generator is
providing a charging output. This will ensure that the detection of a fault will not result in sensitive electrical loads being
subjected to low voltage which may occur during an ECO stop/start with a fault present.
The GWM will illuminate the charge warning indicator in the instrument cluster if fault is detected in the dual battery system
which will result in a degraded power supply.
If a fault is detected the GWM transmits a CAN message to inhibit ECO stop/start operation. In some cases it will record a
DTC, display a warning message in instrument cluster and also illuminate charge warning indicator.
PRIMARY BATTERY - ALL VEHICLES Component Description
The primary battery is located in a plastic tray under the luggage compartment floor in the right side of the luggage

Diagnosis and Testing
Principles of Operation Published: 10-Mar-2014
For a detailed description of the battery system and operation, refer to the relevant Description and Operation section of the
workshop manual. REFER to: Battery and Cables (414-01 Battery, Mounting and Cables, Description and Operation).
Inspection and Verification
CAUTION: Diagnosis by substitution from a donor vehicle is NOT acceptable. Substitution of control modules does not
guarantee confirmation of a fault and may also cause additional faults in the vehicle being checked and/or the donor vehicle.
NOTES:
Generic scan tools may not read the codes listed, or may read only five digit codes. Match the five digits from the scan
tool to the first five digits of the seven digit code listed to identify the fault (the last two digits give additional information
read by the manufacturer-approved diagnostic system).
When performing electrical voltage or resistance tests, always use a digital multimeter (DMM) accurate to three decimal
places, and with an up-to-date calibration certificate. When testing resistance, always take the resistance of the DMM leads
into account.
Check and rectify basic faults before beginning diagnostic routines involving pinpoint tests.
If DTCs are recorded and, after performing the pinpoint tests, a fault is not present, an intermittent concern may be the
cause. Always check for loose connections and corroded terminals.
1. Verify the customer concern.
2. Visually inspect for obvious signs of mechanical or electrical damage.

3. If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to
the next step.
4. If the cause is not visually evident check for Diagnostic Trouble Codes (DTCs) and refer to the DTC Index.
5. Check DDW for open campaigns. Refer to the corresponding bulletins and SSMs which may be valid for the specific
customer complaint and carry out the recommendations as required
