JAGUARDRIVE CONTROL DESCRIPTION Component Description



Item Description 1 Winter mode button 2 DSC/TracDSC mode button 3 ASL (automatic speed limiter) - Reference only, not part of JaguarDrive system 4 Dynamic mode (Supercharged models only) The system is controlled by buttons adjacent to the JaguarDrive Selector located on the floor console. The buttons allow the
selection of one of the following 3 modes:

Special modes off
Winter mode
Dynamic mode (Supercharged models only).
The instrument cluster will display the selected JaguarDrive Control mode in the message center.

The JaguarDrive Control system uses a combination of a number of vehicle sub-systems to achieve the required vehicle
characteristics for the mode selected. The following sub-systems make up the JaguarDrive Control system:

The Engine Management System (EMS)
Automatic transmission
Brake system.

The JaguarDrive Control software is stored in the JaguarDrive Selector module located below the JaguarDrive selector. The
module detects the selection made using the buttons and transmits a signal on the high speed CAN bus, which is received by each of the sub-system control modules.

Each of the affected sub-system control modules contain software, which applies the correct operating parameters to their
controlled system for the JaguarDrive Control mode selection made.

Each sub-system control module also provides a feedback for the selected mode so that the JaguarDrive Control software can
check that all systems have changed to the correct operating parameters.


NOTE: The JaguarDrive Control system is a co-ordinating system only. It CANNOT generate a fault in one of the
participating sub-systems. All participating sub-systems should be FULLY diagnosed before assuming a fault with JaguarDrive
Control. Replacing the JaguarDrive Selector module should not be done until all other options have been exhausted. JAGUARDRIVE CONTROLS

1 Transmission selected gear status 2 MIL (malfunction indicator lamp) 3 Message center The instrument cluster is connected to the TCM via the high speed CAN bus. Transmission status is transmitted by the TCM and displayed to the driver in one of two displays in the instrument cluster. For additional information, refer to 413-01
Instrument Cluster.

Malfunction Indicator Lamp

The MIL (malfunction indicator lamp) is located in the tachometer in the instrument cluster. Transmission related faults which
may affect the vehicle emissions output will illuminate the MIL.
The MIL is illuminated by the ECM (engine control module) on receipt of a relevant fault message from the TCM on the high speed CAN. The nature of the fault can be diagnosed using a Jaguar approved diagnostic system which reads the fault codes stored in the TCM memory.
Transmission Status Display

The transmission status display is located in a LCD (liquid crystal display) at the top of the instrument cluster, between the
speedometer and the tachometer. The LCD shows the JaguarDrive selector position or the selected gear when in manual 'Jaguar Sequential Shift' mode.
The following table shows the displays and their descriptions.

Symbol Description P Park selected R Reverse selected N Neutral selected D Drive selected S Sport mode selected 1 1st gear selected (manual Jaguar sequential shift mode) 2 2nd gear selected (manual Jaguar sequential shift mode) 3 3rd gear selected (manual Jaguar sequential shift mode) 4 4th gear selected (manual Jaguar sequential shift mode) 5 5th gear selected (manual Jaguar sequential shift mode) 6 6th gear selected (manual Jaguar sequential shift mode) The message center is located in the lower center of the instrument cluster. The message center is a LCD to relay vehicle status and operating information to the driver and can display messages relating to a number of the vehicle systems. If a
transmission fault occurs, the message center will display the message 'GEARBOX FAULT'.

TRANSMISSION CONTROL MODULE

The TCM outputs signals to control the shift control solenoid valve and the EPRS (electronic pressure regulating solenoid) to control the hydraulic operation of the transmission.

The TCM processes signals from the transmission speed and temperature sensors, the ECM and other vehicle systems. From the received signal inputs and pre-programmed data, the module calculates the correct gear, torque converter clutch setting
and optimum pressure settings for gear shift and lock-up clutch control.

The ECM supplies the engine management data over the high speed CAN bus. The TCM requires engine data to efficiently control the transmission operation, for example; flywheel torque, engine speed, accelerator pedal angle, engine temperature.
The steering angle sensor and the ABS (anti-lock brake system) module also supply data to the TCM on the high speed CAN bus. The TCM uses data from these systems to suspend gear changes when the vehicle is cornering and/or the ABS module is controlling braking or traction control.

Using the signal inputs and the memorized data, the TCM control program computes the correct gear and torque converter lock-up clutch setting and the optimum pressure settings for gear shift and lock-up clutch control. Special output-side modules
(power output stages, current regulator circuits), allow the TCM to control the solenoid valves and pressure regulators and consequently precisely control the hydraulics of the automatic transmission. In addition, the amount and duration of engine
interventions are supplied to the engine management by way of the CAN bus.
The transmission has a fully electronic JaguarDrive selector with no Bowden cable connection to the transmission. The
transmission selections are made using a rotary JaguarDrive selector which rises from the floor console once the engine is
running. Rotation of the JaguarDrive selector to any of the five positions is sensed by the TCM via the high speed CAN bus. The TCM then reacts according to the selected position. The 'S' (sport) position selection allows the TCM to operate the transmission using the semi-automatic 'Jaguar Sequential Shift'.

Gear selections are sensed by the TCM when the driver operates the steering wheel paddle switches. Once the JaguarDrive selector position is confirmed, the TCM outputs appropriate information on the high speed CAN bus.
If the JaguarDrive selector is in 'D', 'Jaguar Sequential Shift' is temporary and will cancel after a time period or can be cancelled
by pressing and holding the + paddle for approximately 2 seconds.

If the JaguarDrive selector is in 'S', 'Jaguar Sequential Shift' is permanent and can only be cancelled by pressing and holding
the + paddle for approximately 2 seconds or by moving the JaguarDrive selector to the 'D' position.

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.

The functionality for each of the above warning indicators is described in the following sections:

1 and 2. Turn Signal Indicators
The turn signal indicators are controlled by the CJB on receipt of medium speed CAN bus signals from the instrument cluster.
The instrument cluster outputs a voltage to the turn signal indicator switch. The switch contains resistors of different values.
When the switch is operated in either the LH or RH direction, the voltage is passed to a ground connection in the instrument cluster which detects the reduced voltage supplied via the resistors. When the turn signal indicator switch is operated in the
LH or RH direction, the instrument cluster detects the ground voltage and determines whether a LH or RH selection is made.
The instrument cluster transmits a medium speed CAN message to the CJB for operation of the applicable turn signal indicators. The message can contain a number of states for each possible switch position and also an out of range low and
high state for circuit faults and an initial value for the switch neutral position. The turn signal indicators are not subject to the
3 second indicator check when the ignition is switched on.

The RJB (rear junction box) software controls the flash rate of the warning indicator which sends 'ON' and 'OFF' signals to the
instrument cluster which flashes the indicators in a green color. During normal operation, the warning indicator flashes slowly,
accompanied simultaneously by a sound from the instrument cluster sounder. If a fault exists, the RJB transmits a message to the instrument cluster which responds by displaying an appropriate message in the message center.

The hazard warning indicators are controlled by the CJB on receipt of a completed ground path from the hazard warning indicator switch. The CJB outputs a medium speed CAN message to the instrument cluster which operates both the LH and RH turn signal indicators simultaneously. The hazard warning indicators can operate with the ignition switched off, therefore the
CAN message from the CJB will also carry a 'wake-up' message for the instrument cluster. 3. Brake Warning Indicator

This warning indicator is displayed in a red or amber color (dependant on market) as a brake symbol in all markets except
United States of America (USA) which have the word 'BRAKE' in place of the symbol. The indicator is controlled by high speed
CAN messages from the ABS module and the parking brake control module. The indicator is illuminated in a red color for a 3 second indicator check when the ignition is switched on.

The instrument cluster monitors the fluid level in the brake fluid reservoir using a hardwired level switch. If the fluid level falls
to below a determined level, the switch contact is broken and the ABS module detects the low fluid level condition. The instrument cluster illuminates the warning indicator and simultaneously displays a 'BRAKE FLUID LOW' message in the
message center.


NOTE: If both the brake warning indicator and the ABS warning indicator illuminate simultaneously, a major fault in the brake system will have occurred.

The warning indicator also displays parking brake status. When the parking brake is applied, the warning indicator will be
illuminated by the instrument cluster and, if the vehicle is moving, the message 'PARK BRAKE APPLIED' will be also displayed
in the message center in response to a CAN message from the parking brake control module.
If a condition exists where the parking brake cannot be applied, the parking brake control module issues a CAN message to the instrument cluster which flashes the warning lamp on and off and is accompanied with a message 'CANNOT APPLY PARK BRAKE'.
If a fault occurs in the parking brake system, the parking brake control module issues a CAN message to the instrument cluster which illuminates the warning indicator and displays the message 'PARK BRAKE FAULT' in the message
center.
4. Forward Alert Indicator

The forward alert system uses the components of the adaptive speed control system to alert the driver of the presence of a
vehicle ahead. The system can be turned on and off using a switch located in the auxiliary lighting switch when the adaptive
speed control system is off. The indicator is illuminated in an amber color for a 3 second indicator check when the ignition is
switched on.

The forward alert system is controlled by the adaptive speed control module. When the switch is pressed, the forward alert
system is activated and the adaptive speed control module issues a forward alert active message on the high speed CAN bus to the instrument cluster. The forward alert icon in the instrument cluster will illuminate in an amber color and a 'FORWARD
ALERT' message will be displayed in the message center. When the button is pressed a second time, the module issues a
forward alert off CAN message. The forward alert system will be deactivated, the forward alert icon will go off and a message 'FORWARD ALERT OFF' will be displayed in the message center.
5. Automatic Speed Limiter (ASL) Indicator

The ASL is controlled by the ECM (engine control module). An ASL switch is located in the floor console, adjacent to the gear
selector lever. When the ASL switch is pressed, this is sensed by the ECM which issues a high speed CAN message to the instrument cluster. The instrument cluster illuminates the ASL warning indicator in an amber color to show the driver that ASL
is active. The driver sets the required speed using the speed control SET +/- switches on the steering wheel. The selected
speed is shown by the message ' LIMITER SET XXX MPH / K/MH' in the message center. The indicator is illuminated in an
amber color for a 3 second indicator check when the ignition is switched on. ASL can be deselected by pressing the ASL switch,
by depressing the throttle pedal initiating kick-down or by pressing the 'cancel' switch on the steering wheel. The ASL indicator
will go off and the message center will display the message 'limiter cancelled' for 4 seconds. If a fault occurs in the ASL
system, the ECM will send a message to the instrument cluster to illuminate the ASL indicator and display the message 'LIMITER NOT AVAILABLE'.

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.

player is only compatible with standard CD's. All other versions of CD player are compatible with standard CDs and CDs with MP3 or WMA (windows media audio) files.

A portable audio module allows for the connection of a range of portable audio devices to the car’s audio system. The portable
audio module is controlled through the IAM (integrated audio module) and Touch-screen with play back through the car’s
speaker system. The introduction of this system allows the user to import their personal portable media player to interface
with the car, including iPod and other MP3 players, or USB mass storage devices such as memory sticks. MP3 players can also
be controlled through the Touch-screen if they are configured as mass storage devices. Details of how to do this will be
contained in the manufacturers instructions.

The chosen audio device can be plugged into the car using an interface panel located in the floor console between the front
seats. The interface includes a 3.5mm auxiliary jack-plug socket, a 12-volt power supply, a dedicated iPod connector with
charging function, plus a USB2 connector which allows connectivity for a wide variety of USB devices. The USB port also
provides a charging function although it does not support a USB hub. The maximum charging current supplied is 500ma. The
user can connect an iPod and USB device at the same time, changing the source via the Touch-screen. The non selected source
will still charge.

The Jaguar Sound System is the basic audio system which comprises of an IAM (integrated audio module) with no external
amplifier and 8 speakers.
The Jaguar 320W Premium Sound System has the addition of an AUD 8 power amplifier and a 9 speaker system.

The Bowers & Wilkins 440w Surround Sound System additions include an AUD 12 power amplifier, a Dolby Pro-Logic 2 7.1
Surround Sound System, and 14 speakers.

DAB (digital audio broadcasting) is available for most European markets and gives access to digital radio channels for better
sound quality and enhanced functionality depending on local service availability. The DAB (digital audio broadcasting) module
is located in the luggage compartment. The system receives reception signals from the following sources to ensure optimum
signal strength.

DAB band L antenna located in the roof pod antenna module
DAB band III antenna located in the heated rear window.

For NAS vehicles the digital format adopted is satellite radio which specifically links to the Sirius network. The system operates
in the S-band frequency range, and as a result of the use of satellite transmission, has the ability to provide CD quality audio broadcasts over very large areas (typically continents). The satellite radio receiver is located in the luggage compartment. The
system receives reception signals from the satellite radio antenna located in the roof pod module.

Primary user control of the audio system is via the ICP (integrated control panel) and the Touch-screen which are located in the
center of the instrument panel. Control signals from the ICP (integrated control panel) are relayed on the medium speed CAN
(controller area network) bus to the ICM (information control module). The ICM (information control module) relays the control
signals to the rest of the audio system on the MOST (media oriented systems transport) ring. The ICM (information control
module) is the timing master for the MOST (media oriented systems transport) ring and also hosts a gateway function between
the medium speed CAN bus and the MOST (media oriented systems transport) ring. Audio output signals on the Jaguar 320W Premium Sound System and Bowers & Wilkins 440W Surround Sound System are sent on the MOST (media oriented systems
transport) ring from the IAM (integrated audio module) to the power amplifier for speaker output. www.JagDocs.com

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.
