30. CAUTION: Observe the engine temperature warning light. If the
warning light is displayed, switch off immediately and allow to cool.
Failure to follow this instruction may cause damage to the vehicle.

Raise the engine speed to 2000 RPM and maintain at 2000 RPM until the
engine cooling fan operates.


31. CAUTION: Switch off the engine and allow the coolant temperature
to go cold.
Switch the engine off and allow to cool.

32. Visually check the engine and cooling system for signs of coolant
leakage.

33. WARNINGS:


When releasing the cooling system pressure, cover the coolant
expansion tank cap with a thick cloth.


Since injury such as scalding could be caused by escaping steam or
coolant, make sure the vehicle cooling system is cool prior to carrying
out this procedure.
CAUTIONS:


Make sure the coolant level remains above the "COLD FILL RANGE"
lower level mark.


Anti-freeze concentration must be maintained at 50%.


NOTE: When the cooling system is warm, the coolant will be
approximately 10mm above the upper level mark on the expansion tank
with the cap removed.
Check and top-up the coolant if required.

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.

Inspection and Verification


WARNING: Servicing must be carried out by personnel familiar with both vehicle system and the charging and testing
equipment. All operations must be carried out in a well ventilated area away from open flame and heat sources.


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.


NOTE: Check and rectify basic faults before beginning diagnostic routines involving pinpoint tests.

Face Level Registers System Operation

Operation of the face level registers is controlled by the ATC module, using LIN bus messages to the integral stepper motors. The four registers operate together in both the opening and closing phases.

The face level registers can be selected to run in one of two modes; 'automatic' or 'always open'. The mode is selected on the
climate control screen of the TSD.
Refer to: Navigation System (415-01 Information and Entertainment System, Description and Operation).

In the automatic mode, operation of the face level registers is synchronized with the engine START/STOP button. When the
engine starts the ATC module opens the registers. When the engine stops, the ATC module closes the registers.
If a face level register is fouled, when it receives an open or close request, the register concerned makes a number of
attempts to reach the requested position. If the register still does not move, it is left in the fouled position. The remaining
registers will continue to open and close as normal.

The automatic mode is disabled when the climate control system is off. The ATC module closes the registers if they are open in the automatic mode and the climate control system is selected off.

Diagnostics

If a fault occurs with the face level registers, a DTC (diagnostic trouble code) is stored in the ATC module. The DTC can be read using the Jaguar approved diagnostic system. The Jaguar approved diagnostic system can also initiate a self test routine
to check the operation of the face level registers.
Refer to: Climate Control System (412-00 Climate Control System - General Information, Diagnosis and Testing).


Air Ducts Component Description

The air ducts distribute air from the heater assembly to the registers and vents in the instrument panel and the center floor
console. Air ducts also direct air from the heater assembly into the front and rear footwells.

Registers and Vents

The registers control the flow and direction of air from the air ducts. The instrument panel contains four face level registers;
one at each end and two mounted centrally. For the rear seat occupants, two registers are installed in the rear face of the
center floor console. All of the registers incorporate vertical and horizontal directional vane adjustment and full air flow
adjustment down to zero.

The four face level registers in the instrument panel each contain an integral stepper motor. The stepper motors enable the
registers to rotate between the open and closed positions. In the open position, the registers have normal appearance and
functionality. In the closed position, the registers present a smooth surface flush with the surrounding instrument panel.

The vents are fixed outlets. There are four vents in the upper surface of the instrument panel; one in each end to direct air
onto the side windows and two along the front edge to direct air onto the windshield.
