The TCM can be reprogrammed using a Jaguar approved diagnostic system using a flash code. The TCM processor has a 440 kb internal flash memory. Of this capacity, approximately 370 kb are used by the basic transmission program. The remainder,
approximately 70 kb is used to store vehicle-specific application data.
Engine Stall
If the vehicle stalls it will coast down in gear, with the transmission providing drive to the engine. A restart can be attempted
at this point and the engine may start and the driver can continue.
If the coast down speed reduces such that the speed of the engine is less than 600 rev/min, the transmission will go to
neutral, D illumination will flash in the instrument cluster. The driver needs to select neutral or park and then press the brake
pedal to restart the engine.
If the start/stop button is pressed when driving, the message ENGINE STOP BUTTON PRESSED is displayed in the message
center but there will be no change to the ignition state. If the driver requires to switch off the engine, the start/stop button
must be pressed for a second time. The engine will be stopped and will be back driven by the transmission as the vehicle
coasts down. When the engine speed is less than 600 rev/min the transmission engages neutral (flashing D illumination in the
instrument cluster). When vehicle speed is less than 2 km/h (1.2 mph) Park is engaged. The JaguarDrive selector automatically
rotates back to its lowered P position and the vehicle ignition is switched off.
The park engagement is prevented in a stall case as the ignition power is on and D was the last selected gear. The park
engagement speed at ignition off is from the least value of the wheel speeds (CAN signal) and transmission output speed (internal signal).
TRANSMISSION Component Description
The transmission comprises the main casing which houses all of the transmission components. The main casing also
incorporates an integral bell housing.
A fluid pan is attached to the lower face of the main casing and is secured with bolts. The fluid pan is sealed to the main
casing with a gasket. Removal of the fluid pan allows access to the Mechatronic valve block. The fluid pan has a magnet
located around the drain plug which collects any metallic particles present in the transmission fluid.
A fluid filter is located inside the fluid pan. If the transmission fluid becomes contaminated or after any service work, the fluid
pan with integral filter must be replaced.
The integral bell housing provides protection for the torque converter assembly and also provides the attachment for the
gearbox to the engine cylinder block. The torque converter is a non-serviceable assembly which also contains the lock-up clutch
mechanism. The torque converter drives a crescent type pump via drive tangs. The fluid pump is located in the main casing,
behind the torque converter.
The main casing contains the following major components:
Input shaft
Output shaft
Mechatronic valve block which contains the solenoids, speed sensors and the TCM Three rotating multiplate drive clutches
Two fixed multiplate brake clutches
A single planetary gear train and a double planetary gear train.

selector.
Rotation of the JaguarDrive selector allows the selection of P, R, N and D. By depressing the JaguarDrive selector and rotating
clockwise from the D position, S mode can be selected. The JaguarDrive selector is fully electronic rotary transmission selector
with no mechanical connection to the transmission.
The JaguarDrive selector rises from the JaguarDrive selector module once the engine is running. When the engine is stopped
with the JaguarDrive selector in any position other than N, it retracts into the JaguarDrive selector module again. If the
selector is in position N when the engine is stopped, it remains in the raised position for up to 10 minutes, for use in a drive
through car wash for example. After 10 minutes the selector automatically retracts into the JaguarDrive selector module. The
selector also retracts if P is selected within the 10 minute period.
If the JaguarDrive selector does not rise from the console when the engine is started, but electrical power is supplied to the
selector, the retracted selector can still be rotated to make selections. If electrical power to the JaguarDrive selector is lost,
the selector will not rise from the console when the engine is started and the retracted selector will not rotate.
The JaguarDrive selector contains an internal interlock solenoid to prevent the selector from being rotated when the engine is
not running.
The engine can be stopped with the JaguarDrive selector in any position. Once the engine is stopped the selector will
automatically reset to the P position and the transmission park lock will be engaged, except if the selector is moved to the N
position when the engine is stopped.

1 Fuel supply connection 2 Electrical connector 3 Flange locking ring and seal 4 Sucking jet connector 5 Fuel pump module 6 Fuel pick up filter 7 Level sensor float 8 RH level sensor 9 Fuel filter 10 Pressure relief valve 11 Pump supply to flange connection 12 The fuel pump is a variable speed rotary vane type. The pump is energized by the fuel pump relay which is located in the RJB and the FPDM which is located under the RH floor pan above the rear suspension stabilizer bar. The relay and FPDM are controlled by the ECM.
A fine mesh filter is located in the lower section of the pump module. This provides filtration to the fuel as it is drawn into the
module. There is a winged filter on the fuel pump that gives additional protection and a life time fuel filter integrated into the
flange which eliminates the need for an additional filter further downstream in the fuel system.
The RH fuel level sensor is mounted into the pump module housing.
FUEL PUMP DRIVER MODULE (FPDM)
The FPDM is located on a bracket which is integral with the charcoal canister. The module is attached to one end of the canister with a bracket.
The fuel pump operation is regulated by a FPDM which is controlled by the ECM. The FPDM regulates the flow and pressure supplied by controlling the operation of the fuel pump using a PWM (pulse width modulation) output.
The FPDM is powered by a supply from the fuel pump relay in the RJB. The fuel pump relay is energized on opening the driver's door, pressing the start button only or pressing the start button and the footbrake (which initiates engine cranking). The FPDM supplies power to the fuel pump, and adjusts the power to control the speed of the fuel pump and thus the pressure and flow
in the fuel delivery line.
A PWM signal from the ECM tells the FPDM the required speed for the fuel pump. The on time of the PWM signal represents half the fuel pump speed, e.g. if the PWM signal has an on time of 50%, the FPDM drives the pump at 100%.
The FPDM will only energize the fuel pump if it receives a valid PWM signal, with an on time of between 4% and 50%. To switch the fuel pump off, the ECM transmits a PWM signal with an on time of 75%.
The output pressure from the fuel pump will change with changes of engine demand and fuel temperature. The ECM monitors the input from the fuel rail LP sensor and adjusts the speed of the fuel pump as necessary to maintain a nominal output
pressure of 450 kPa (4.5 bar; 65.3 lbf/in.2
), except during engine start-up. At engine start-up the target pressure for the fuel
delivery line is 630 kPa (6.3 bar; 91.4 lbf/in.2
).
If the SRS (supplemental restraint system) outputs a crash signal on the high speed CAN (controller area network), the ECM de-energizes the fuel pump relay to prevent any further fuel being pumped to the engine.
If the ECM does not detect pressure in the fuel delivery line, it stops, or refuses to start the engine and stores the appropriate DTC (diagnostic trouble code).
The ECM receives a monitoring signal from the FPDM. Any DTC's produced by the FPDM are stored by the ECM.
DTC's can be retrieved from the ECM using an approved Jaguar diagnostic system. The FPDM itself cannot be interrogated by the approved Jaguar diagnostic system.

Face Level Registers System Operation
Operation of the face level registers is controlled by the ATC module, using LIN bus messages to the integral stepper motors. The four registers operate together in both the opening and closing phases.
The face level registers can be selected to run in one of two modes; 'automatic' or 'always open'. The mode is selected on the
climate control screen of the TSD.
Refer to: Navigation System (415-01 Information and Entertainment System, Description and Operation).
In the automatic mode, operation of the face level registers is synchronized with the engine START/STOP button. When the
engine starts the ATC module opens the registers. When the engine stops, the ATC module closes the registers.
If a face level register is fouled, when it receives an open or close request, the register concerned makes a number of
attempts to reach the requested position. If the register still does not move, it is left in the fouled position. The remaining
registers will continue to open and close as normal.
The automatic mode is disabled when the climate control system is off. The ATC module closes the registers if they are open in the automatic mode and the climate control system is selected off.
Diagnostics
If a fault occurs with the face level registers, a DTC (diagnostic trouble code) is stored in the ATC module. The DTC can be read using the Jaguar approved diagnostic system. The Jaguar approved diagnostic system can also initiate a self test routine
to check the operation of the face level registers.
Refer to: Climate Control System (412-00 Climate Control System - General Information, Diagnosis and Testing).
Air Ducts Component Description
The air ducts distribute air from the heater assembly to the registers and vents in the instrument panel and the center floor
console. Air ducts also direct air from the heater assembly into the front and rear footwells.
Registers and Vents
The registers control the flow and direction of air from the air ducts. The instrument panel contains four face level registers;
one at each end and two mounted centrally. For the rear seat occupants, two registers are installed in the rear face of the
center floor console. All of the registers incorporate vertical and horizontal directional vane adjustment and full air flow
adjustment down to zero.
The four face level registers in the instrument panel each contain an integral stepper motor. The stepper motors enable the
registers to rotate between the open and closed positions. In the open position, the registers have normal appearance and
functionality. In the closed position, the registers present a smooth surface flush with the surrounding instrument panel.
The vents are fixed outlets. There are four vents in the upper surface of the instrument panel; one in each end to direct air
onto the side windows and two along the front edge to direct air onto the windshield.

rear window heater switch is pressed or the engine stops.
Automatic operation during a journey is initiated when low ambient air temperatures are experienced and the vehicle has been
travelling for a set period of time above a threshold speed. In this instance, no feedback is given to the driver to inform him
the rear window heater is operational (the switch LED is not illuminated). The duration of heater operation is variable depending on the ambient air temperature, vehicle speed and the amount of time the vehicle has been travelling.
Windshield Heater (Where Fitted)
Windshield heater operation is only enabled when the engine is running. The ATC module controls operation of the windshield heater using two relays in the EJB (engine junction box). When windshield heater operation is required, the ATC module broadcasts a message to the CJB on the medium speed CAN bus. On receipt of the message, the CJB energizes the relays by providing a ground path for both relay coils. This allows a battery feed to flow across the relays to power the windshield left
and right heater elements.
There are two modes of windshield heater operation; manual and automatic.
Manual operation is activated by pressing the windshield heater switch on the integrated control panel. When the switch is
pressed, the status LED in the switch illuminates and the windshield heater elements are energized. Manual operation is discontinued when the windshield heater switch is pressed a second time, 5 minutes have elapsed (the heating phase), or the
engine stops. If manual operation is discontinued by the engine stopping, the previous heating phase is resumed if the engine
is re-started within 30 seconds.
There are two variants of automatic operation; automatic operation at the start of a journey and automatic operation during a
journey.
Automatic operation at the start of a journey is initiated if the ambient air temperature is below 5 °C (41 °F). In this instance,
the switch LED is illuminated and the heater elements are energized for 6.5 minutes. Automatic operation is discontinued if the windshield heater switch is pressed or the engine stops.
Automatic operation during a journey is initiated when low ambient air temperatures are experienced and the vehicle has been
travelling for a set period of time above a threshold speed. In this instance, no feedback is given to the driver to inform him
the windshield heater is operational (the switch LED is not illuminated) and the duration of operation is variable depending upon the ambient air temperature, vehicle speed and the amount of time the vehicle has been travelling.
Exterior Mirror Heaters
Operation of the exterior mirror heaters is fully automatic and not controllable by the driver. Exterior mirror heater operation is
determined by ambient air temperature and windshield wiper status. When ambient air temperature reaches a pre-determined
level, the ATC module broadcasts an exterior mirror heating request to the door modules over the medium speed CAN bus. On receipt of this message, the door modules provide feed and ground connections to both exterior mirror heater elements.
The amount of time the exterior mirror heaters are operational increases if the windshield wipers are switched on. This ensures
the mirrors remain mist free in damp and wet conditions, where there is an increased risk of misting.
Seat Heaters (Where Fitted)
There are four seat heater settings available; off, 1, 2 and 3, which can be selected on the home and climate control screens
of the TSD. The heat setting is relayed to the vehicle occupants through a graduated display on the TSD.
Operation of the heated seats is controlled by the ATC module. When the ATC module receives a heating request from the TSD, it broadcasts a message to the CJB over the medium speed CAN bus. The CJB then provides a hardwired 12 V supply to the three heater elements in the related front seat. The heater elements, two in the seat cushion and one in the seat squab,
are wired in series. The ATC module monitors seat temperature using a temperature sensor located in each seat cushion. The CJB provides the temperature sensors with a 5 V supply. The level of the returned voltage back to the CJB is proportional to the seat temperature. The value of the return signal is broadcast to the ATC module, over the medium speed CAN bus, which allows it to control the seat temperature to the required level. The ATC module will suspend or disable operation of the seat heaters if any of the following occur:
Battery voltage exceeds 16.5 ± 0.3 V for more than 5 seconds. Seat heating is re-enabled when battery voltage
decreases to 16.2 ± 0.3 V.
If a short or open circuit is detected.
If the seat heat temperature rises significantly above the target temperature setting.
The graduated display on the TSD remains illuminated until the seat heaters are turned off or the engine stops. If the engine
is restarted within 30 seconds the seat heater resumes the previous heating level.

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.

Battery and Charging System - General Information - Battery Care
Requirements
Description and Operation
1. INTRODUCTION
This document defines the requirements for care and maintenance of batteries, and the standard of battery care at dealers and
retailers for new vehicles.
This applies to all types of 12 Volt Lead Acid Batteries used in Jaguar and Land Rover vehicles whether they are conventional
flooded technology or Absorbed Glass Mat (AGM – also known as Valve Regulated Lead Acid (VRLA)) technology and also
applies to both Primary, Secondary and Auxiliary Batteries. AGM batteries offer improved resistance to cycling as seen in stop
start applications.
In order to prevent damage to the battery and ensure a satisfactory service life, all processes detailed within this document
must be rigorously adhered to.
It is equally important therefore to note the following key points:
All new vehicles leave the factory with either a transit relay installed and/or have a transit mode programmed into the
vehicle control modules. The transit relay must be removed and the transit mode disabled (where applicable) using an
approved diagnostic system, NOT MORE THAN 72 HOURS before the customer takes delivery.
The battery can be discharged by the following mechanisms:
- Self Discharge: - A lead acid battery will very slowly discharge itself due to its own internal chemical processes
whether it is connected to a vehicle or not.
- Quiescent Discharge: - The vehicle electrical systems when connected to the battery will draw charge from the
battery.
12 Volt Lead Acid Batteries rely on internal chemical processes to create a voltage and deliver current. These processes and
the internal chemical structure of the battery can be damaged if the battery is allowed to discharge over a number of weeks /
months, or is left in a discharged state for a lengthy time period.
On vehicles with conventional ignition keys, these must not be left in the ignition lock barrel when the transit relay
has been removed, otherwise quiescent current will increase and the battery will discharge more rapidly.
For keyless vehicles, the Smart Key must be stored at least 5m (16 ft) away from the vehicle when the vehicle is
parked or stored.
AGM Batteries are fully sealed and cannot have the electrolyte level topped up.
NOTE: Dealers and retailers involved in the storage / handling of vehicles and replacement batteries have a responsibility
to ensure that only a fully charged battery may be processed through the distribution selling chain.
2. GENERAL RULES FOR BATTERY CARE
2.1 Dealer Demonstration Vehicles
Vehicles used as dealer demonstrator(s), in a showroom, must be connected to a JLR approved showroom conditioner capable
of delivering 50 Amps. This will prevent the battery from being damaged.
2.2 Software Reflash, SDD work or Ignition On related workshop activities
Due to the high electrical current demand and high depth of discharge that can occur during vehicle software re-flash activities,
SDD work or ignition on (power mode 6) related work in the workshop, vehicles that are undergoing such activities MUST have a
JLR approved power supply capable of delivering 50 Amps or more.
2.3 Extended Vehicle Rework
For any extended vehicle rework that results in consuming vehicle power, either the battery should be disconnected or a JLR
approved power supply connected.
2.4 Jump Starting New vehicles before they have been delivered to the customer
It is the dealer / retailers responsibility to make sure the battery is not allowed to discharge by following the
instructions and processes defined in this manual.
However, if circumstances dictate that a new vehicle must be jump started due to a discharged battery whilst the
vehicle is in the dealer / retailers care, the battery on this vehicle must be replaced with a new one prior to delivery
to the customer at the dealer / retailers liability.
The vehicle should also undergo investigation as to why the battery became discharged.
Do not connect the jump starting cable to the negative (-) terminal of the battery. Always connect to the recommended
earth point. As defined in the owners handbook or service documentation for that vehicle. 2.5 AGM Batteries
AGM batteries must not be charged above 14.8 Volts. Doing so will damage them.
AGM Batteries must be tested with a capable battery tester as detailed in the Equipment section (Section 5) of this

Battery, Mounting and Cables - Battery and Cables - Overview
Description and Operation
OVERVIEW
Single Battery Vehicles Published: 18-Jun-2014
Mounted on the battery negative terminal is a BMS (battery monitoring system) module. The BMS module is integral with the
battery negative cable and is controlled by the ECM (engine control module).
CAUTION: To avoid damaging the battery monitoring system module, always use a suitable body ground point rather than
the battery negative terminal when connecting a slave power supply to the vehicle.
If a new battery is fitted to the vehicle, the BMS module will require re-calibrating using the Jaguar approved diagnostic
system.
Fitted on the battery positive terminal is a transit relay. The transit relay must be removed from the vehicle during the
Pre-Delivery Inspection (PDI). For additional information, refer to the PDI Manual.
The vehicle battery provides power to the BJB (battery junction box). The BJB contains 3 megafuses, delivering power to the RJB (rear junction box), the CJB (central junction box) and the EJB (engine junction box). In addition to containing fuses and
relays, the RJB and RJB contain software to control a number of vehicle systems. These functions are covered in the appropriate sections of this manual.
Dual Battery System Vehicles - TD42.2L Engine Variants Only
Two batteries are fitted to accommodate the dual battery system used for the Stop/Start system.
A primary battery is located in the luggage compartment floor in a plastic molded tray and secured with a metal rod. The
secondary battery is located in the DBJB (dual battery junction box).
The primary battery is a 90Ahr, 850A CCA AGM Battery.
The secondary battery is a 14Ahr, 200A CCA Absorbed Glass Mat (AGM) Battery.
A BMS (battery monitoring system) control module is mounted on the primary battery negative terminal. The BMS control
module is integral with the battery negative cable and is controlled by the GWM (gateway module).
CAUTION: To avoid damaging the BMS control module, always use the ground (negative (-)) terminal stud point on the
right side top mount. Never connect directly to the primary battery negative terminal when connecting a slave power supply to
the vehicle, the BMS control module can be damaged.
If a new primary battery is fitted to the vehicle, the BMS control module will require re-calibrating using a Jaguar approved
diagnostic system.
When the vehicle leaves the factory, a transit relay is fitted to the battery positive terminal. The transit relay is connected to
the CJB which limits the electrical functions to essential items only, to reduce loads on the primary battery. The transit relay must be removed from the vehicle during the PDI (Pre-Delivery Inspection). For additional information, refer to the PDI.
The primary battery provides power to the BJB. The BJB contains three megafuses, delivering power to the RJB, the EJB and the starter motor and generator. In addition to containing fuses and relays, the RJB and CJB contain software to control a number of vehicle systems. These functions are covered in the appropriate sections of this manual.
A jump start terminal is located adjacent to the EJB. A cover protects the terminal when not in use. If jump starting is
required, the cover must be removed and the positive (+) jump lead attached securely. The negative (-) jump lead is attached
to a stud located on the right side top mount in the engine compartment. The cover must be fitted to the positive terminal
when not in use.
Dual Battery System
The dual battery system is used on vehicles with the stop/start system. The dual battery system prevents the vehicle
electrical systems being subjected to undesirably low voltages during repeated engine restarts. If the electrical systems are
subject to low voltages the customer may notice degraded performance of components and systems and incorrect fault DTC
(diagnostic trouble code)'s may be stored.
The dual battery system isolates all electrical components and systems sensitive to low supply voltage from the primary
battery while an engine start is in progress, and supplies them from the secondary battery. Without the dual battery system,
the electrical power required by the TSS (Tandem Solenoid Starter) motor to crank the engine for each start would cause a
voltage drop across the entire vehicle electrical network, and cause control modules to function incorrectly and in some cases
reset and/or record DTC's.
If the dual battery system is unable to prevent electrical supplies to the vehicle systems being subjected to low voltage levels
during engine stop/start operations, due to the condition of the primary and/or secondary batteries or a system fault, the
stop/start feature is disabled.
