JAGUARDRIVE SELECTOR System Operation
Rotation of the JaguarDrive selector to any of the five positions is sensed by the TCM (transmission control module) via the
high speed CAN bus. A LIN bus connection is also provided, but is only used in the event of a CAN bus failure as a back-up. The TCM then reacts according to the selected position. The JaguarDrive selector is a magnetic system using Hall effect sensors to determine the position of the selector.
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 which is received by the instrument cluster to display the gear selection information in the message center.
Refer to: Information and Message Center (413-08 Information and Message Center, Description and Operation).
The paddles can also be used on a temporary basis when the JaguarDrive selector is in the D (drive) position to override the
automatic gear selection if required.
PARK INTERLOCK AND NEUTRAL LOCK
Neutral lock is a requirement for the JaguarDrive selector. The selector is always locked at ignition on when the engine is not
running, except after an engine stall when the selector is not in P (park) or N (neutral).
If, when driving with the JaguarDrive selector in S, D or R (reverse) at a speed of more than 5 km/h (3 mph), the driver selects
P or N:
Without the brake pedal pressed, the JaguarDrive selector will be immediately locked once the vehicle speed falls to
below 5 km/h (3 mph).
With the brake pedal pressed, the JaguarDrive selector will remain locked for as long as the brake pedal remains
pressed, regardless of vehicle speed.
The transmission will only engage park once the vehicle speed is less than 2 km/h (1 mph).
If the driver selects N and releases the brake pedal with a vehicle speed of less than 5 km/h (3 mph), the JaguarDrive selector
will be locked 2 seconds after N is selected. The selector will remain locked until the driver presses the brake pedal again.
To ensure that a driver request to change from a non-driving range (N for example) to a driving range (D for example), the park
interlock and neutral lock features are used in conjunction with the intermediate position.
If the transmission receives a range change request without the brake pedal pressed, the TCM initiates a soft lock function. The transmission will remain in park or neutral, depending on the starting position.
If a transmission position letter is flashing in the message center and the vehicle has no drive, the driver must:
Press the brake pedal.
Reselect N or P on the JaguarDrive selector.
Select the required driving range, ensuring that the brake pedal is pressed.
Rocking Function
The rocking function compliments the neutral lock function. For all changes from a non-driving range to a driving range, it is
necessary to press the brake pedal (to release either the park interlock or neutral lock).
In situations where the driver will require to change the gear selection from R to D, or from D to R, without brake pedal input
(car park maneuvering, 3 point turns or 'rocking' the vehicle from a slippery surface for example), the rocking function gives a 2
second lock delay when N is selected on the JaguarDrive selector and the brake pedal is not pressed.
Intermediate Position
If the JaguarDrive selector is rotated slowly from P to S and back to position P with the brake pedal pressed, the R or D
position display letter in the message center will flash and the transmission will remain in park or neutral depending on the
previous starting position of the selector.
If the brake pedal is released when R or D is flashing in the message center and the JaguarDrive selector is rotated to the R or
D position, the required range will not be selected and the transmission will remain in park or neutral, depending on the
previous starting position. This feature is known as soft lock.
If the driving range letter in the message center is flashing and the vehicle has no drive, the driver should depress the brake
pedal to reselect N or P, and then select the required driving range while the brake pedal remains pressed.

1 Latch 2 Strap 3 Locking cylinder 4 Operating lever 5 Upper cable 6 Cable joint 7 Lower cable 8 Cable bracket 9 Park interlock lever If a vehicle requires recovery/transportation, the emergency park release mechanism is used to manually disengage the park
lock and engage the transmission in neutral.
The emergency park release mechanism consists of an operating lever that is connected to a park interlock lever on the
transmission by an upper and lower cable assembly.
The operating lever is installed in the floor console, under the trim panel between the drinks holder and the cubby box. The
park interlock lever is attached to the transmission selector shaft.
One end of the operating lever is attached to a base by a hinge pin. A locking cylinder is installed in the other end of the
operating lever, to secure the operating lever to the base. The operating lever is raised by pulling on a strap.
When operated, the emergency park release mechanism turns the transmission selector shaft.
To disengage the park lock:
Open the cubby box lid and the drinks holder lid.
Remove the trim panel from between the drinks holder and the cubby box.
Rotate the locking mechanism of the emergency park release lever 90 degrees counterclockwise.
Apply the footbrake, pull the operating lever upwards and ensure it locks in the vertical position.
Raising the operating lever causes the emergency park release cable to rotate the park interlock lever on the transmission,
which disengages the parking pawl and engages neutral. This allows the vehicle to freewheel.
To re-engage the park lock:
Hold the strap on the operating lever, release the latch and lower the operating lever to the horizontal position.
Lock the operating lever by turning the locking mechanism 90 degrees clockwise.
Install the trim panel.
Close the cubby box lid and the drinks holder lid. www.JagDocs.com

Speed Control - V8 5.0L Petrol/V8 S/C 5.0L Petrol - Speed Control - Overview
Description and Operation
OVERVIEW
Speed Control
The speed control system is integrated with the engine management system and uses fueling intervention to automatically
maintain a set vehicle speed. Once engaged, the system can also be used to accelerate the vehicle without using the
accelerator pedal.
The speed control system comprises the following components:
On/Off/Suspend switch
'+' and '-' (set/accelerate and decelerate) steering wheel switches
Resume switch
Clock spring
Speed control warning indicator.
Adaptive Speed Control
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 adaptive speed control system comprises the following components:
Adaptive speed control sensor
Adaptive speed control module
Steering wheel control switches
ECM (engine control module)
Electric throttle actuator
ABS (anti-lock brake system) module and pump
Adaptive speed control warning indicator (in the instrument cluster).

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

1 Set speed adjustment switch 2 Time gap switch (only on vehicles with adaptive speed control fitted) 3 Cancel switch 4 Resume switch The speed control switches are located on the RH (right-hand)side of the steering wheel. The switches are connected via fly
leads to the clock spring. The speed control switches are resistive ladder type switches which vary the resistance of a 5 volt
signal sent to them. The signal is returned along a LIN bus to the instrument cluster. The instrument cluster routes the control signals to the ECM on the medium speed CAN
Speed control is engaged by rotating the speed adjustment switch to the + or - positions. Once engaged the speed can be
varied by the speed adjustment switches. Each press of the speed adjustment switch will increase or decrease the set speed
in steps of 1 mph (2 kph).
ADAPTIVE SPEED CONTROL MODULE
The adaptive speed control module, located on the drivers side at the bottom of the 'A' post. The control module is connected
to the other vehicle systems via the high speed CAN bus. Signals from the adaptive speed control forward looking radar sensor are received on a dedicated CAN bus between the two modules.
ADAPTIVE SPEED CONTROL RADAR SENSOR
The adaptive speed control radar sensor is located in the front bumper, on the RH side above the radiator grill behind the bumper cover. The sensor is connected to the adaptive speed control, module via a private CAN bus. If the unit is replaced in service the unit must be re-aligned vertically. Horizontal alignment is achieved by putting the sensor in service mode using an
approved Jaguar diagnostic system.

Item Description 1 Forward alert switch The forward alert system utilizes the adaptive speed control system components. Forward alert is turned on and off
independently of adaptive speed control, via a switch mounted in the lower outboard knee bolster switchpack. Forward alert
will notify the driver by means of a chime, a warning indicator in the instrument cluster and an indication in the message
center, when a target vehicle comes into range. The system will NOT use throttle or brake intervention to slow the vehicle.
The forward alert switch is connected to the instrument cluster in a resistive ladder with the luggage compartment opening
switch and the fuel filler flap switch. The instrument cluster sends the forward alert information to the Adaptive speed control
module on the CAN bus.
WARNING: The system is intended as a driver aid and should be used as such. The system is NOT a collision warning or
avoidance device.
The system sensitivity can be adjusted in the same manner as the adaptive speed control, via the steering wheel mounted
switches. Each adjustment is accompanied by a message in the message center. FORWARD ALERT SWITCHES
