Item Description 1 Filler cap 2 Vent hose connection 3 Expansion hose connection 4 Level sensor The expansion tank is installed in the engine compartment, on the LH upper suspension housing.
A filler cap and level sensor are incorporated into the expansion tank. A MAX level marking is molded into the interior of the
tank below the filler cap. Cold fill levels are molded onto the exterior of the tank.
The expansion tank provides the following functions:
Service fill.
Coolant expansion during warm-up.
Air separation during operation.
System pressurization by the filler cap.

The expansion tank has an air space of approximately 0.5 liter (1.06 US pints), above the MAX level, to allow for coolant
expansion. EXPANSION TANK

1 Fuel supply connection 2 Electrical connector 3 Flange locking ring and seal 4 Sucking jet connector 5 Fuel pump module 6 Fuel pick up filter 7 Level sensor float 8 RH level sensor 9 Fuel filter 10 Pressure relief valve 11 Pump supply to flange connection 12 The fuel pump is a variable speed rotary vane type. The pump is energized by the fuel pump relay which is located in the RJB and the FPDM which is located under the RH floor pan above the rear suspension stabilizer bar. The relay and FPDM are controlled by the ECM.
A fine mesh filter is located in the lower section of the pump module. This provides filtration to the fuel as it is drawn into the
module. There is a winged filter on the fuel pump that gives additional protection and a life time fuel filter integrated into the
flange which eliminates the need for an additional filter further downstream in the fuel system.
The RH fuel level sensor is mounted into the pump module housing.
FUEL PUMP DRIVER MODULE (FPDM)



The FPDM is located on a bracket which is integral with the charcoal canister. The module is attached to one end of the canister with a bracket.

The fuel pump operation is regulated by a FPDM which is controlled by the ECM. The FPDM regulates the flow and pressure supplied by controlling the operation of the fuel pump using a PWM (pulse width modulation) output.

The FPDM is powered by a supply from the fuel pump relay in the RJB. The fuel pump relay is energized on opening the driver's door, pressing the start button only or pressing the start button and the footbrake (which initiates engine cranking). The FPDM supplies power to the fuel pump, and adjusts the power to control the speed of the fuel pump and thus the pressure and flow
in the fuel delivery line.

A PWM signal from the ECM tells the FPDM the required speed for the fuel pump. The on time of the PWM signal represents half the fuel pump speed, e.g. if the PWM signal has an on time of 50%, the FPDM drives the pump at 100%.
The FPDM will only energize the fuel pump if it receives a valid PWM signal, with an on time of between 4% and 50%. To switch the fuel pump off, the ECM transmits a PWM signal with an on time of 75%.
The output pressure from the fuel pump will change with changes of engine demand and fuel temperature. The ECM monitors the input from the fuel rail LP sensor and adjusts the speed of the fuel pump as necessary to maintain a nominal output
pressure of 450 kPa (4.5 bar; 65.3 lbf/in.2
), except during engine start-up. At engine start-up the target pressure for the fuel
delivery line is 630 kPa (6.3 bar; 91.4 lbf/in.2
).
If the SRS (supplemental restraint system) outputs a crash signal on the high speed CAN (controller area network), the ECM de-energizes the fuel pump relay to prevent any further fuel being pumped to the engine.

If the ECM does not detect pressure in the fuel delivery line, it stops, or refuses to start the engine and stores the appropriate DTC (diagnostic trouble code).
The ECM receives a monitoring signal from the FPDM. Any DTC's produced by the FPDM are stored by the ECM.
DTC's can be retrieved from the ECM using an approved Jaguar diagnostic system. The FPDM itself cannot be interrogated by the approved Jaguar diagnostic system.

The lighting system has an 'auto' lights function which is controlled by the CJB on receipt of signals from the rain/light sensor located at the top of the windscreen. The exterior lights are turned on or off in response to ambient light signals from the
rain/light sensor on a LIN (local interconnect network) bus connection to the CJB . The auto lights can also be activated when the windshield wipers are activated by signals from the rain sensor, which is located at the top of the windshield or when the
driver activates the wipers in the fast wipe position.

Two levels of headlamp specification are available; halogen or xenon. In certain markets the headlamps feature a cornering
lamp or a static bending lamp which illuminates the area at the side of the vehicle when turning into driveways for example.
North American Specification (NAS) vehicles have a side marker lamp installed in the headlamp assembly. Replacement of any
of the headlamp bulbs requires removal of the headlamp assembly.

The tail lamp comprises two separate lamp assemblies. The turn signal indicator, side and stop lamps and reverse lamps are
located in each rear fender tail lamp assembly. The rear fog lamps are located in separate units attached to the luggage
compartment lid. A side marker lamp is fitted to the rear fender tail lamp assembly and is fitted in all markets.

Two systems of headlamp leveling are available; manual leveling which is only available on halogen headlamps and static
dynamic leveling which is available on xenon headlamps. The manual system uses a thumbwheel rheostat to adjust the
vertical alignment of the headlamps to compensate for differing vehicle loading. The static dynamic system uses height
sensors fitted to the front and rear suspension and a headlamp leveling module which periodically monitors the vehicle
attitude and adjusts the headlamp vertical alignment accordingly.

dependant on a particular ignition mode status. The side lamps will also be illuminated when the lighting control switch is in
the AUTO position and a 'lights on' signal is received by the CJB from the rain/light sensor Side Marker Lamps (NAS only)

The side marker lamp is located in the outer part of the headlamp assembly. The side marker lamp uses a W5W wedge fitting
bulb. The bulb is fitted into a holder which connects with contacts in the headlamp housing. The holder is fitted into an
aperture which connects with contacts in the headlamp housing. The side marker lamp is active at all times when the side
lamps are active.

AUTOMATIC HEADLAMP OPERATION

The automatic headlamp function is a driver assistance system. The driver can override the system operation by selection of
side lamp or headlamp on if the ambient light conditions require front and rear lighting to be active. The automatic headlamp
system uses a light sensor and the CJB, which are connected via a LIN (local interconnect network) bus to control the headlamp functionality. The light sensor is incorporated in the rain/light sensor located on the inside of the windshield, below
the rear view mirror. The wiper system also uses the rain/light sensor for automatic wiper operation.

The light sensor measures the ambient light around the vehicle in a vertical direction and also the angular light level from the
front of the vehicle. The rain/light sensor uses vehicle speed signals, wiper switch position and the park position of the front
wipers to control the system. The automatic headlamp operation uses ambient light levels which are monitored by photodiode
incorporated in the rain/light sensor. The rain/light sensor sends a lights on/off request to the CJB on the LIN bus, which responds by switching on the low beam headlamps, front side lamps and rear tail lamps. The automatic headlamps are
activated under the following conditions:

Twilight
Darkness
Rain
Snow
Tunnels
Underground or multistoried car parks.

Operation of the automatic headlamps requires the ignition to be in ignition mode 6, the lighting control switch to be in the
'AUTO' position and a lights on request signal from the light sensor. If the rain sensor signal activates the fast speed wipers,
the low beam headlamps are activated, providing the lighting control switch is in the 'AUTO' position.

HEADLAMP LEVELING

Headlamp leveling provides for the adjustment of the vertical aim of the headlamps. The leveling system is primarily required
to minimise glare to other road users when a heavy load is in the rear of the vehicle. Two systems of headlamp leveling are
available; manual and static dynamic.
Manual Headlamp Leveling

The manual system uses a thumbwheel rheostat to adjust the vertical alignment of the headlamps to compensate for differing
vehicle loading. The rotary thumbwheel is located on the auxiliary lighting switch, adjacent to the illumination dimmer
thumbwheel. Three positions are available to adjust the headlamps to a position to prevent glare to other road users.
Static Dynamic Headlamp Leveling
The static dynamic headlamp leveling system uses the following components:
Front and rear vehicle height sensors
Two headlamp leveling, vertical adjustment motors
Headlamp leveling module
Ignition in mode 6
Vehicle speed information from ABS module.
The static dynamic system uses height sensors fitted to the front and rear suspension and a headlamp leveling module which
periodically monitors the vehicle attitude and adjusts the headlamp vertical alignment accordingly.

Static dynamic headlamp leveling is controlled by a headlamp leveling module located in the lower instrument panel, behind
the glovebox.

The height sensors are both located on the RH side of the vehicle. The front sensor is attached to the front suspension lower arm with a strap and to the front sub frame with a bracket and 2 bolts. The rear sensor is attached to the rear suspension
upper control arm with a cable tied clip and to the rear sub frame with a bracket and 2 bolts. Each sensor has 3 connections to
the headlamp leveling module; power, ground and signal.

DAYTIME RUNNING LAMPS (DRL)

Refer to DRL section for details. Refer to: Daytime Running Lamps (DRL) (417-04 Daytime Running Lamps (DRL), Description and Operation).
REAR LAMP ASSEMBLY

The rear lamp assembly is a 2 piece unit, with one part located in the rear quarter panel and the second part attached to the
luggage compartment lid. The outer rear lamp assembly is located in a recess in the vehicle body. The lamp is secured with 2
studs inboard studs on the lamp body which are secured to the vehicle body with 2 nuts. A third outboard stud and nut secures
