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

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
compartment, adjacent to the spare wheel. The battery is vented via a tube which is connected with a T piece to the vent from

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.

resistors. The returned signal voltage is detected by the instrument cluster which outputs a message on the medium speed
CAN bus to the CJB to activate the headlamps. The reference voltage to the auto headlamp exit delay switch is routed through 4 resistors which is detected by the instrument cluster which outputs a message on the medium speed CAN bus to the CJB that auto headlamp or exit delay has not been selected.

AUTOLAMPS - When the lighting control switch is in the auto headlamp position, the reference voltage flows through 4 of the
resistors. The returned signal voltage is detected by the instrument cluster which outputs a message on the medium speed
CAN bus to the CJB to activate the autolamp function. The reference voltage to the autolamp exit delay switch is routed through 4 resistors which is detected by the instrument cluster which outputs a message on the medium speed CAN bus to the CJB that auto headlamp has been selected.
AUXILIARY LIGHTING SWITCH

Headlamp Leveling Rotary Thumbwheel (Halogen headlamps only)

A power supply is passed to the headlamp leveling thumbwheel from the ignition relay in the EJB. Depending on the position of the thumbwheel, the voltage passes through 1, 2 or 3 resistors connected in series. The voltage through the resistors is
passed to the headlamp leveling motor controller in each headlamp. The received voltage is determined as a request for the
appropriate level position and the controller powers the headlamp level motors to the applicable position for each headlamp.
Rear Fog Lamp Switch

The instrument cluster supplies a reference voltage and return to the rear fog lamp switch. The fog lamp switch is a
non-latching, momentary switch.

When the fog lamp switch is off the reference voltage is passed through a 1Kohm resistor. The voltage through the resistor is
returned to the instrument cluster that determines that no request for fog lamp operation has been made.

When the driver presses the fog lamp switch, the reference voltage is passed through a 330 ohm resistor. The change is return
voltage is sensed by the instrument cluster which determines fog lamp operation has been requested. The instrument cluster
transmits a medium speed CAN bus signal to the RJB providing the lighting control switch is in the correct position. The RJB reacts to the message and provides a power supply to the 3 LED (light emitting diode)'s in each rear fog lamp. A fog lamp
warning lamp in the instrument cluster will also be illuminated when the fog lamps are operating.

The RJB will only activate the rear fog lamps if the headlamps are selected on or are active with auto headlamp activation. When the headlamps are turned off the fog lamps are also turned off. When the headlamps are next switched on, the fog
lamps will not be activated until the driver requests fog lamp operation.


NOTE: The fog lamps do operate when DRL (daytime running lamps) are active.

HEADLAMP LEVELING

Manual Headlamp Leveling - Halogen headlamps only

A power supply is passed to the headlamp leveling motor in each headlamp from the ignition relay in the EJB. When a signal voltage is received from the headlamp leveling rotary thumbwheel, the headlamp leveling motor controller in each headlamp
uses the power supply to operate the motors and move the headlamp to the requested position.
Static Dynamic Headlamp Leveling - Xenon headlamps only

The headlamp leveling module receives a power supply from the ignition relay in the EJB. The same power supply is also supplied to the headlamp leveling motor in each headlamp assembly. The front and rear height sensors are connected to the
headlamp leveling module and receive a power and ground from the module. Each sensor has a signal line to the headlamp
leveling module to return height information to the module. The module uses the height signals from the sensors to calculate
the vehicle attitude and supplies a signal to each motor to power the headlamp to the required position.
