Anti-Lock Brake System System Operation

ABS controls the speed of all road wheels to ensure optimum wheel slip when braking at the adhesion limit. The wheels are prevented from locking to retain effective steering control of the vehicle.

The brake pressures are modulated separately for each wheel. Rear brake pressures are controlled to maintain rear stability on
split friction surfaces.

Dynamic Stability Control

DSC (dynamic stability control) uses brakes and powertrain torque control to assist in maintaining the yaw stability of the
vehicle. While the ignition is energized the DSC function is permanently enabled, unless selected off using the DSC switch.

DSC enhances driving safety in abrupt maneuvers and in under-steer or over-steer situations that may occur in a bend. The
ABS module monitors the yaw rate and lateral acceleration of the vehicle, steering input and individual wheel speeds, then selectively applies individual brakes and signals for powertrain torque adjustments to reduce under-steer or over-steer
conditions.
In general:

In an under-steer situation the inner wheels are braked to counteract the yaw movement towards the outer edge of the
bend.
In an over-steer situation the outer wheels are braked to prevent the rear end of the vehicle from pushing towards the
outer edge of the bend.

The ABS module monitors the tracking stability of the vehicle using inputs from the wheel speed sensors, the steering angle sensor, and the yaw rate and lateral acceleration sensor. The tracking stability is compared with stored target data. Whenever
the tracking stability deviates from the target data, the ABS module intervenes by applying the appropriate control strategy. The following interactions occur in an intervention situation:

High speed CAN signal to the ECM, to reduce engine torque. Application of braking to the appropriate corner of the vehicle.
Trac DSC

TracDSC is an alternative setting of DSC with reduced system interventions. With TracDSC engaged, traction may be somewhat
increased, although stability may be reduced compared to normal DSC. TracDSC is intended for use only on dry tarmac, by
suitably experienced drivers and should not be selected for other surfaces or by drivers with insufficient skill and training to
operate the vehicle safely with the TracDSC function engaged.

The less restrictive TracDSC setting may be preferred, for example, by expert drivers engaged in high performance driving on
dry Tarmac surfaces such as tracks and circuits.
Switching between DSC and Trac DSC:

engine oil).

Oil Consumption Test

The amount of oil an engine uses will vary with the way the vehicle is driven in addition to normal engine-to-engine variation.
This is especially true during the first 16,100 km (10,000 miles) when a new engine is being broken in or until certain internal
components become conditioned. Vehicles used in heavy-duty operation may use more oil. The following are examples of
heavy-duty operation:

Trailer towing applications
Severe loading applications
Sustained high speed operation
Engines need oil to lubricate the following internal components:
Cylinder block cylinder walls
Pistons and piston rings
Intake and exhaust valve stems
Intake and exhaust valve guides
All internal engine components

When the pistons move downward, a thin film of oil is left on the cylinder walls. As the vehicle is operated, some oil is also
drawn into the combustion chambers past the intake and exhaust valve stem seals and burned.
The following are examples of conditions that can affect oil consumption rates:
Engine size
Operator driving habits
Ambient temperatures
Quality and viscosity of oil
Engine is being run in an overfilled condition (check the oil level at least five minutes after a hot shutdown with the
vehicle parked on a level surface. The oil level should not be above the top of the cross-hatched area and the letter "F"
in FULL).

Operation under varying conditions can frequently be misleading. A vehicle that has been run for several thousand miles on
short trips or in below-freezing ambient temperatures may have consumed a "normal" amount of oil. However, when checking
the engine oil level, it may measure up to the full mark on the oil level indicator due to dilution (condensation and fuel) in the
engine crankcase. The vehicle then might be driven at high speeds on the highway where the condensation and fuel boil off.
The next time the engine oil is checked it may appear that a liter of oil was used in about 160 km (100 miles). Oil
consumption rate is about one liter per 2,400 km (1,500 miles).

Make sure the selected engine oil meets Jaguar specification and the recommended API performance category "SG" and SAE
viscosity grade as shown in the vehicle Owner's Guide. It is also important that the engine oil is changed at the intervals
specified for the typical operating conditions.
The following diagnostic procedure is used to determine the source of excessive oil consumption.


NOTE: Oil use is normally greater during the first 16,100 km (10,000 miles) of service. As mileage increases, oil use
decreases. High speed driving, towing, high ambient temperature and other factors may result in greater oil use.

1. Define excessive consumption, such as the number of miles driven per liter of oil used. Also determine customers
driving habits, such as sustained high speed operation, towing, extended idle and other considerations.
2. Verify that the engine has no external oil leaks as described under Engine Oil Leaks in this section.
3. Carry out an oil consumption test:
Run the engine to normal operating temperature. Switch engine OFF and allow oil to drain back for at least five
minutes .
With vehicle parked on level surface, check the engine oil level.
If required, add engine oil to set level exactly to the FULL mark.
Record the vehicle mileage.
Instruct the customer to return for a level check after driving the vehicle as usual for 1,610 km (1000 miles).
Check the oil level under the same conditions and at the same location as the initial check.

NOTE: If the oil consumption rate is unacceptable go to Step 4.

4. Check the Positive Crankcase Ventilation (PCV) system. Make sure the system is not plugged.

5. Check for plugged oil drain-back holes in the cylinder head and cylinder block.
6. If the condition still exists after carrying out the above tests go to step 9.

7. Carry out a cylinder compression test. Refer to the Compression Test procedure in this section. This can help determine
the source of oil consumption such as valves, piston rings or other areas.
8. Check valve guides for excessive guide clearance. Install new valve stem seals after verifying valve guide clearance.

9. Worn or damaged internal engine components can cause excessive oil consumption. Small deposits of oil on the tips of
the spark plugs can be a clue to internal oil consumption.

OPERATION System Operation

The fuel pump is a variable-speed rotary-vane type, which operates in a fuel pump module located in the RH side of the fuel tank. A venturi transfer pump is located in the RH side of the tank. The fuel pump module is secured in the fuel tank with a bayonet style locking ring that is welded into the tank structure. The fuel pump module has an integral top plate for the
external pipe work and electrical connectors.

Fuel level is biased towards the RH compartment in the fuel tank by drawing fuel through the internal cross over pipe via the jet pump, which serves to deliver a constant supply of fuel to the transfer pump and swirl pot assembly. High pressure fuel
from the fuel pump is directed through the jet pump's orifice, creating a low pressure area to be formed in the cross over pipe.
The fuel is drawn into this low pressure area in the cross over pipe and directed into the swirl pot delivery pipes.
Fuel is pumped from the fuel pump to the fuel rail via the integral filter and pressure relief valve.

The pressure relief valve assists engine starting by retaining a pre-set fuel pressure in the supply pipe and fuel rail. The
pressure relief valve also limits fuel rail pressure due to temporary vapor increase in hot conditions and pressure caused by
sudden load changes, for example, a fully open to closed throttle transition.

To meet ORVR (on-board refueling vapor recovery) requirements, the fuel tank and associated components are designed to
minimize fuel vapor loss during refueling. This is achieved by preventing fuel vapor from the fuel tank venting directly to the
atmosphere. Instead fuel vapor is directed into the EVAP (evaporative emission) charcoal canister where it is stored before
being purged at intervals to the engine’s intake manifold.

North American Specification (NAS) vehicles feature additional connections and pipes at the rear of the filler head and also
incorporates a Diagnostic Monitoring Tank Leakage (DMTL) pump for leak detection requirements.

Blind Spot Monitoring System Operation

The purpose of the blind spot monitoring system is to detect an object moving with a positive velocity relative to the radar
module, on either side of the vehicle, at a distance of up to 2.5 meters laterally and in an area from the door mirror up to 7.0
meters behind the module. These criteria identify an overtaking vehicle within the blind-spot area and within a typical
carriageway lane width, while eliminating other objects that are not relevant, either because of their position, they are
stationary, traveling in the opposite direction, or being overtaken. A vehicle is classed as a heavy goods vehicle, car or
motorcycle. A motorcycle is defined as a minimum size of 2.0m long, 0.8m wide (widest point) and 1.1m high. The system is
not affected by the mass of the overtaking vehicle providing all identification criteria, including relative velocity of (16km/h -
10mph) or above, is met.

The system emits radar pulses and analyses the reflections, identifying anything that moves into the blind spot zone. Having
detected another vehicle in the defined blind spot zone it alerts the driver by illuminating the amber alert icon located in the
appropriate exterior mirror.


NOTE: If an overtaking vehicle is detected on both sides of the vehicle simultaneously, the warning alert icons in both
mirrors will illuminate.

The light lens is shaped so as to minimize the visibility to other drivers. The LED (light emitting diode)’s are located towards
the outside extremity of the mirror face, within the peripheral view of the driver but not in any area of the mirror where they
could obscure or distract from the image.



Item Description 1 Warning alert icon 2 System status warning indicator The LED lighting sequence is as follows;
Amber alert LED icon permanently lit - system operational, vehicle detected in blind spot area No LED’s lit – system active no vehicle detected in blind spot area Amber status LED permanently lit - system not active or faulty
The system has operating limitations and is automatically turned off under certain operating conditions. During these
operating conditions the amber status LED is permanently lit. The system operating limitations are as follows;

The area surrounding the radar face of the module must be clear of metallic items
The system is inactive until vehicle speed is greater than 16km/h - 10mph (amber status LED permanently lit) The system is inactive if an approved trailer is connected to the vehicle (amber status LED permanently lit) The system is inactive when reverse gear or park is selected (amber status LED permanently lit)
If either of the radar signals are blocked or distorted, for example by water, the radar face of the module is covered in mud,
sleet or snow the system may detect this and be disabled with the amber status LED permanently lit together with a ‘blind spot monitoring blocked’ message displayed in the instrument cluster message center. The system is disabled until the
blockage is cleared.

If there is a fault in the system the amber status LED is permanently lit and a ‘blind spot monitoring not available’ message displayed in the instrument cluster message center. The system is disabled until the fault is rectified.
System fault and blockage warnings are as follows;

CAUTION: Diagnosis by substitution from a donor vehicle is NOT acceptable. Substitution of control modules does not
guarantee confirmation of a fault, and may also cause additional faults in the vehicle being tested and/or the donor vehicle.
NOTES:


If the control module is suspect and the vehicle remains under manufacturer warranty, refer to the Warranty Policy and
Procedures manual (section B1.2), or determine if any prior approval programme is in operation, prior to the installation of a
new module.


Generic scan tools may not read the codes listed, or may read only five digit codes. Match the five digits from the scan
tool to the first five digits of the seven digit code listed to identify the fault (the last two digits give additional information
read by the manufacturer approved diagnostic system).


When performing voltage or resistance tests, always use a digital multimeter (DMM) accurate to three decimal places,

The digital radio format adopted for NAS vehicles is satellite radio. Satellite service providers transmit a signal from their
up-link facility (which is the original point of transmission of data, voice or other information through an antenna system) to a
satellite where the signal is then down linked to both the terrestrial repeater network and the individual satellite car radios.
The radio switches between the satellite signal and the repeater network signal depending on the strength of the signal at any
given time.
The Sirius satellite system comprises:
Satellites
Ground repeaters
Up-link ground stations
Radio receiver systems

The Sirius satellite radio system uses three satellites on an inclined elliptical orbit. This ensures that each satellite spends
approximately 16 hours a day over the continent of the USA, with at least one satellite over the country at any one time.

The satellites beam their signals down to the ground where the signal is picked up by receivers or is transmitted to repeater
stations to cover built up areas where the signal is obscured. The satellite service comprises over 100 channels of digital
entertainment which is provided by subscription requiring a monthly payment.

Operation of the satellite radio system is the same as the radio operations with selections made through the Touch-screen and
ICP to access and navigate the system functions.

The satellite radio receiver is a dedicated tuner which is controlled by the ICM on the MOST ring. The receiver filters the
signals from the satellite radio antenna. Information is transmitted on the MOST ring and processed by the ICM. The processed
information is sent out to the power amplifier or IAM (with internal amplifier) and broadcast through the speaker system.

No configuration procedure is required if the satellite radio receiver is replaced. Calibration of the satellite radio receiver using
the Jaguar approved diagnostic equipment enables updates to be downloaded as new technology becomes available or any
fault concerns require software updates.
Satellite Radio Antenna



The satellite radio antenna is located in the roof pod and is shared with the navigation system GPS (global positioning system)
antenna where fitted. The roof pod is located externally in a central position towards the rear of the roof.

Similar to the DAB system the satellite radio antenna is designed with 50 ohm output impedance. The satellite radio receiver
is fitted with 50 ohm fakra II connectors to ensure compatibility with the antenna. For optimum performance 50 ohm low loss
coaxial cable is used between the antenna and receiver.

The antenna is designed to receive one of two signals, using the strongest signal with the least distortion to process for audio
output. For example, if the vehicle drives into a tunnel, the signal received will change from a satellite signal to a repeater
station signal maintaining the strongest signal. SATELLITE RADIO (NAS VEHICLES ONLY)

the roof pod and is shared with the DAB (digital audio broadcasting) band L antenna or satellite radio antenna where fitted.
The roof pod is located externally in a central position towards the rear of the roof.

The GPS antenna is designed with 50 ohm output impedance. The navigation computer is fitted with 50 ohm fakra II connectors to ensure compatibility with the antenna. For optimum performance 50 ohm low loss coaxial cable is used between
the antenna and navigation computer.
It is possible for the GPS antenna to lose the signal from the GPS satellites; In hilly or tree lined areas
Built up areas with tall buildings
In multi storey car parks
In garages
In tunnels
On bridges
During heavy rain or thunderstorms

When the signal is lost the navigation computer will continue to give guidance using memory mapped data from the DVD map until the signal is restored.

TMC/VICS FM Antenna

Data messages for both TMC (traffic message channel) and VICS (vehicle information and communication system) are received
through the FM antennas and diversity antenna module located in the heated rear window.
VICS Beacon Antenna (Japan Only)



The VICS (vehicle information and communication system) beacon antenna receives infra red and RF (radio frequency) traffic
data signals from road side transmitters. The antenna is connected to the navigation computer which incorporates a VICS
(vehicle information and communication system) receiver.
