SPEED CONTROL System Operation
The speed control system uses inputs from the brake lamp/brake test switch, the APP sensor, the ECM and the ABS module.
Speed control is operated by the driver using only the steering wheel switches. When speed control is active, the ECM regulates the PWM (pulse width modulation) signals to the fuel injectors to adjust the fuel supply as required to maintain the
set speed.
During speed control operation, the ECM controls vehicle speed by adjusting fuel injection duration and timing. When the accelerator pedal is pressed with speed control active, the ECM outputs a calculated throttle angle signal in place of the actual throttle angle signals produced by the APP sensor. The calculated throttle angle is derived from fuel demand.
The minimum set speed for speed control is 18 mph (30 (km/h). Speed control is automatically suspended if the following
conditions apply:
Vehicle speed falls below 18 mph (30 km/h)
The brake pedal is pressed
The cancel button is pressed
Neutral, park or reverse gear is selected
The difference between actual speed and the set speed is too great
If the engine speed becomes near to the red line (maximum engine speed)
If the accelerator pedal is used to accelerate beyond the set speed for too long.
ADAPTIVE SPEED CONTROL
The adaptive speed control system comprises the following components:
Adaptive speed control sensor
Adaptive speed control module
Steering wheel control switches
ECM
Electric throttle actuator
ABS module and pump Adaptive speed control warning indicator.
The adaptive speed control system uses a forward looking radar sensor to scan the road ahead, looking for objects that are
moving at a different rate to itself. When a target is identified the adaptive speed control system will monitor the time gap
between it and the target vehicle. When that gap falls below a set driver selected level the adaptive speed control system will
intervene slowing the vehicle by backing off the throttle and/ or applying the brakes, until the correct gap is attained. The
driver can chose between four gap settings, 1, 1.4, 1.8 and 2.2 seconds.
The system will detect but not react to the following:
Vehicles in the oncoming lane
Stationary vehicles
Pedestrians
Vehicles not in the same lane.
Adaptive speed control is active when the vehicle is moving. Adaptive Speed Control only functions when a set speed is
entered in normal speed control mode. The adaptive speed control system only intervenes with the set speed when it detects
a target vehicle, and then only if the minimum time gap is breached.
It is important to note that the system is intended for use in limited driving situations, does not remove control and
responsibility from the driver, and at all times can be quickly overridden. The adaptive speed control system is not a collision
warning system and will not react to stationary objects. The system does not operate below a minimum speed of
approximately 30 km/h (20 mph) since it is unsuitable for use in cities or congested traffic. The system is best suited to main
roads/ highways with gradual bends.
The ECM, throttle body and throttle control are unchanged from those used for non adaptive speed control variants.
The adaptive speed control system is based on the use of a front mounted radar sensor. The sensor transmits a 1.5° wide
beam forward of the vehicle and detects the returning signals reflected off other vehicles and objects ahead.
The 1.5° wide radar beam is mechanically scanned at a rate of 10 sweeps/second across a total arc of 15° centered on the
Page 1642 of 3039

longitudinal axis of the vehicle. The radar operates at millimetric wavelengths (76 - 77 GHz) and transmits a frequency
modulated continuous wave signal at a relatively low power level (no high power pulses).
With the ignition ON, the adaptive speed control module is powered up but no radar transmissions are emitted until the
vehicle is in motion.
In follow mode a set speed is selected in the normal speed control manner and this speed is maintained until a slower vehicle
is encountered in the lane ahead. When the vehicle ahead comes within the effective range of the radar sensor, the system
identifies it as a target vehicle and an icon is illuminated on the instrument cluster to indicate that the system is in "follow
mode". When the distance between the two vehicles closes to a set time gap, the adaptive speed control system closes the
throttle and if necessary applies the brakes to maintain the set time gap. Follow mode is effectively a closed loop system. If
several vehicles are ahead, the closest vehicle is chosen as the target to follow. If the target vehicle moves out of radar range,
or if either vehicle changes lane or drops below the minimum operating speed, the system exits follow mode and the follow
mode icon is extinguished. The adaptive speed control system will only raise its speed to the originally set speed, it will not
accelerate past this speed to maintain a time gap.
Driver operation of the foot brake or control switches will immediately cancel adaptive speed control.
When the vehicle is in follow mode the follow mode warning indicator is illuminated in the instrument cluster and the current
gap setting will be displayed in the message center.
The radar sensor detects three primary parameters of objects within the scanned arc. These are:
Range
Relative velocity
Angle.
Range: The radar sensor detects the presence and ranges of different vehicles and objects within the scanned arc up to a
distance of approximately 130 meters. The transmitted signal frequency changes continuously in a cyclic pattern (modulation).
This means that, in the time taken for the signal wave front, to travel to and from a target vehicle (or other object), the
transmission frequency will have changed. The difference between the received signal frequency and the new transmission
frequency is proportional to the distance between the transmitting vehicle and the target vehicle.
Relative velocity: When the signal is reflected off a vehicle moving at a different speed (opening or closing gap) an effect
known as the Doppler shift causes an extra frequency modulation to be imposed on the signal. This Doppler frequency varies
with the relative speed of the vehicle being followed, enabling the system to differentiate between vehicles traveling at
different speeds and also between moving vehicles and stationary objects.
Angle: Using a narrow angle beam to scan horizontally enables the system to distinguish between vehicles in different lanes
and between vehicles and roadside objects.
System Restrictions
The adaptive speed control system is only intended to provide enhanced speed control as described above in certain restricted
conditions. The following points should be noted: Item Description 1 Forward Alert warning indicator 2 Follow mode warning indicator

6. Adaptive Speed Control Indicator
The adaptive speed control system is controlled by the adaptive speed control module. Operation of the SET +/- switches on
the steering wheel will activate the system. Operation of the switches is detected by the adaptive speed control module. The
module issues a high speed CAN message to the instrument cluster which illuminates the adaptive speed control indicator, when the system is in 'follow mode', in an amber color and displays a 'SETSPEED XXX MPH / KM/H' message in the message
center. The indicator is illuminated in an amber color for a 3 second indicator check when the ignition is switched on.
7. Anti-lock Braking System (ABS) Warning Indicator
The ABS warning indicator is controlled by the ABS module. If a fault in the ABS system is detected by the ABS module, the module issues a high speed CAN message to the instrument cluster to illuminate the ABS warning indicator in an amber color and display the message 'ABS FAULT' in the instrument cluster. The indicator is illuminated in an amber color for a 3 second
indicator check when the ignition is switched on. If a fault is present when the ignition is on, the bulb will remain illuminated
after the 3 second indicator check period.
NOTES:
The 'ABS FAULT' message is not displayed in NAS markets).
If both the ABS warning indicator and the brake warning indicator illuminate simultaneously, a major fault in the brake system will have occurred.
On NAS vehicles, the ABS warning indicator is also used for parking brake operation. The NAS warning indicator does not have 'ABS' on the icon and will function as described previously for the parking brake operation of the brake warning indicator.
8. Engine Malfunction Indicator Lamp (MIL)
The MIL warning indicator is controlled by the ECM and illuminated by the instrument cluster on receipt of a message on the high speed CAN bus from the ECM. The indicator is illuminated in an amber color for a 3 second indicator check when the ignition is switched on.
If the MIL remains illuminated after the engine is started or illuminates when driving, a fault is present and must be
investigated at the earliest opportunity. Illumination of the MIL warning indicator alerts the driver to an OBD (on-board
diagnostic) fault which will cause excessive emissions output. This may relate to either an engine management system fault or
a transmission.
9. Tire Pressure Monitoring System (TPMS) Warning Indicator
The TPMS warning indicator is illuminated by the instrument cluster on receipt of a medium speed CAN message from the TPMS module. The indicator is illuminated in an amber color for a 3 second indicator check when the ignition is switched on.
If the indicator illuminates and is accompanied by the message 'TYRE PRESSURE SYSTEM FAULT' in the message center, then a
TPMS fault has occurred. If the indicator illuminates and accompanied by a different message, then a low tire pressure has
been detected, a spare wheel has been fitted or a TPMS sensor has failed.
10. Airbag Warning Indicator
The airbag warning indicator is controlled by the instrument cluster. The indicator is illuminated in an amber color for the 3
second indicator check when the ignition is switched on. The indicator remains illuminated after the 3 second period has
expired until the instrument cluster receives a turn off message on the high speed CAN bus from the RCM (restraints control module).
11. Front Fog Lamp Indicator
The green colored front fog lamp indicator is controlled by the CJB and illuminated by the instrument cluster on receipt of a front fog lamp on message on the medium speed CAN bus from the CJB. The indicator is illuminated for as long as the front fog lamps are active. The front fog lamp indicator is not subject to the 3 second indicator check when the ignition is switched
on.
12. Dynamic Stability Control (DSC) Indicator
The DSC warning lamp is controlled by the ABS module and illuminated by the instrument cluster in response to messages received on the high speed CAN bus. The indicator is illuminated in an amber color for the 3 second indicator check when the ignition is switched on. The DSC warning indicator, are permanently illuminated in an amber color if the instrument cluster
receives a high speed CAN message from the ABS module relating to one of the following faults:
Traction control fault
Yaw control fault
Engine drag torque control fault
Panic Brake Assist (PBA) fault
Signal missing relating to either traction control active, yaw control active or DSC switch input.
The above faults will also generate an applicable DSC and ABS warning message in the message center. The DSC warning
indicator will flash at 2 Hz for if the traction control or yaw control is active when the DSC system is enabled. If the DSC
system is switched off, the warning indicator will be permanently illuminated until the DSC system is subsequently
re-activated.
13. Safety Belt Warning Indicator
The safety belt warning indicator operates for both the driver and passenger safety belts. The warning indicator is controlled by

The indicators can be split into two groups;
instrument cluster controlled and externally controlled.
Instrument cluster controlled warning indicators are dependent on software logic within the instrument cluster for activation.
The cluster software controls the indicator illumination check at ignition on (power mode 6).
Externally controlled indicators are supplied with current from another vehicle system control module or illuminated by the
instrument cluster software on receipt of a bus message from another vehicle sub-system. The indicator illumination check at
ignition on (powermode 6) is also controlled by the sub-system module for these indicators.

information from other systems:
ABS (anti-lock brake system) module - Road speed signal
TCM (transmission control module) - Reverse gear engaged signal
Trailer module - Trailer attached to vehicle
The module also outputs messages on the medium speed CAN bus which are received by the integrated audio module. The integrated audio module processes these messages and converts them into Media Orientated System Transport (MOST) signals
which are passed to the audio system power amplifier. These signals are then used by the power amplifier to emit the
applicable warning tones from the front or rear audio speakers when an object is detected by the front or rear parking aid
sensors. A warning tone can also be emitted to alert the driver to a fault in the parking aid system.
The control module has a diagnostic connection via the medium speed CAN bus to enable faults to be retrieved using the
Jaguar approved diagnostic equipment. Additionally an on-board diagnostic routine within the control module constantly
monitors the system and alerts the driver to a system fault by emitting a 3 second continuous tone through the rear audio
system speakers when the ignition is switched on. If front parking aid sensors are fitted, the control switch LED will also flash
6 times.
Parking Aid Sensors
Four ultrasonic sensors are located in the front (if fitted) and rear bumpers.
Each sensor has a three pin connector which mates with a bumper harness, which in turn is connected to the main body
harness. Three pins provide for power supply, ground and signal lines to and from the parking aid module.
The parking aid module controls the operation of each sensor using a digital output on the signal line. The module controls the
sensor in one of two modes; combined transmitter and receiver mode or receiver mode only.
Parking Aid Switch
The parking aid switch is located in the instrument panel switch pack, above the touch screen. The switch is the LH switch with an integral LED.
The switch is a non-latching push switch which allows the driver to select the parking aid system on or off. When pressed, the
switch momentarily connects a ground to the parking aid module.
The LED indicates when the parking aid system is active. The LED is controlled by the parking aid module.
NOTE: The control switch allows the driver to activate/deactivate the parking aid system if operation is required or not
required.

7 Low frequency antenna - front 8 Low frequency antenna - center 9 Low frequency antenna - rear 10 Radio frequency receiver 11 Start control module 12 CJB (central junction box) 13 Instrument cluster 14 Megafuse (250 amp)
System Operation
The passive start function prevents the vehicle from being started by unauthorized persons. It does this by immobilizing the
ignition, fuel and engine crank functions. The system is automatic and requires no input from the driver.
At the request of the CJB, the keyless vehicle module prompts each of the Low Frequency (LF) antennae to output a signal. When the Smart Key is in the vehicle cabin, it detects the LF signals and responds with a Radio Frequency (RF)
data-identification signal back to the keyless vehicle module via the RF receiver.
If the data received matches that stored in the keyless vehicle module it continues the passive start process by
communicating a 'Smart Key valid’ signal to the CJB via the medium speed CAN (controller area network) bus.
Once the CJB receives the authorization and confirms a response with an internal calculation, it passes the result to the
instrument cluster on the medium speed CAN bus.
Before the instrument cluster sends a mobilization signal to the ECMit will exchange encrypted data with: The electric steering lock mechanism to authorize unlocking the steering column.
The RJB to authorize fuel pump operation. Once the RJB receives the authorization and confirms the response with an internal calculation, it will enable the FPDM (fuel pump driver module).
The CJB to authorize the ignition status. If the drive selector is in the park position and the driver presses the brake
pedal and simultaneously presses the start/stop switch, the CJB interprets this as an engine crank request. Before the
engine crank request is allowed, the CJB compares a brake pressure signal received from the ABS module. The brake pressure signal is compared to an internally stored threshold value within the CJB. If the signal is greater than the
stored threshold value, a crank request signal is sent to the ECM on the high speed CAN bus.
Once these factors have been confirmed, and the vehicle is in 'Park', the engine can be started by pressing the brake pedal and
the Stop/Start button simultaneously.
NOTES:
If the keyless vehicle module fails to locate the Smart Key, the message 'SMART KEY NOT FOUND PLEASE INSERT IN
SLOT' will appear in the instrument cluster message center. When inserted the start control module will read the transponder
within the Smart Key. If the transponder identification is valid, authorization will be transmitted to the instrument cluster on
the LIN (local interconnect network) bus.
When the vehicle is delivered from the factory the passive start function is inhibited. In this condition the vehicle can
only be started by placing the Smart Key in the start control module. The system should be switched on during the Pre-Delivery
Inspection (PDI) using the Jaguar approved diagnostic system. For additional information, refer to the PDI Manual.
To ensure optimum long term reliability of the smart key the battery must be replaced with a brand new, unused battery. If a
used battery is installed the "SMART KEY BATTERY LOW" message may not be cleared. To avoid contamination of the contacts
the battery should be removed from its packaging and installed into the smart key while wearing gloves. To confirm that the
replacement battery is working correctly press the unlock button twice while holding the smart key outside the vehicle, then
enter the vehicle with the smart key, press the start button and confirm that the "SMART KEY BATTERY LOW" message is not
displayed.
Start Control Module Component Description
The start control module is used if the keyless vehicle module is unable to authorise the Smart Key.
If the keyless vehicle module is unable to identify the Smart Key, for example if the Smart Key battery voltage is low or there
is local RF interference, the transponder within the Smart Key can be read in the conventional manner. The driver will be
alerted to this by a chime and a message in the instrument cluster message center 'SMART KEY NOT FOUND PLEASE INSERT IN
SLOT'.
Once inserted the start control module will read the transponder within the Smart Key. If the transponder identification is
valid, authorization will be transmitted to the instrument cluster on the LIN bus.
NOTE: Inserting the Smart Key into the start control module will not charge the Smart Key battery. The battery is
non-chargeable and must be replaced if defective.
