selector.

Rotation of the JaguarDrive selector allows the selection of P, R, N and D. By depressing the JaguarDrive selector and rotating
clockwise from the D position, S mode can be selected. The JaguarDrive selector is fully electronic rotary transmission selector
with no mechanical connection to the transmission.

The JaguarDrive selector rises from the JaguarDrive selector module once the engine is running. When the engine is stopped
with the JaguarDrive selector in any position other than N, it retracts into the JaguarDrive selector module again. If the
selector is in position N when the engine is stopped, it remains in the raised position for up to 10 minutes, for use in a drive
through car wash for example. After 10 minutes the selector automatically retracts into the JaguarDrive selector module. The
selector also retracts if P is selected within the 10 minute period.

If the JaguarDrive selector does not rise from the console when the engine is started, but electrical power is supplied to the
selector, the retracted selector can still be rotated to make selections. If electrical power to the JaguarDrive selector is lost,
the selector will not rise from the console when the engine is started and the retracted selector will not rotate.

The JaguarDrive selector contains an internal interlock solenoid to prevent the selector from being rotated when the engine is
not running.

The engine can be stopped with the JaguarDrive selector in any position. Once the engine is stopped the selector will
automatically reset to the P position and the transmission park lock will be engaged, except if the selector is moved to the N
position when the engine is stopped.

Inspection and Verification


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.
1. Verify the customer concern.

2. Visually inspect for obvious signs of damage and system integrity.

Visual Inspection
Mechanical Electrical
Check for stuck/jammed switches and buttons
Visibly damaged or worn components
Loose or missing fasteners

3. If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to
the next step.
4. If the cause is not visually evident, check for Diagnostic Trouble Codes (DTCs) and refer to the DTC Index.

8 LH (left-hand) fuel level sensor 9 RH (right-hand) fuel level sensor and fuel pump module 10 RCM (restraints control module)

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.
Fuel System Schematic Diagram



Item Description 1 Fuel injector (8 off) 2 Fuel rail www.JagDocs.com

15 Fuel pump module The fuel tank is a saddle type tank, blow moulded from HDPE (high density polyethylene). The tank is located forward of the
rear suspension and is mounted using two metal straps. The tank is a sealed unit with the only internal access being through
the fuel pump module aperture on the top of the tank.

The fuel pump module flange has a six pin external connector which provides the electrical connections for the fuel pump and
both fuel level sensors. A quick release connector provides for the connection of the fuel feed pipe.

The flange is fitted with a locking ring and seal. The seal locates in a groove on the tank. The locking ring locates and clamps
on the encapsulated ring that is moulded into the fuel tank. The flange has a tag which locates in the top of the tank to
ensure correct orientation.

A carrier within the tank provides for the mounting of the passive side jet pump tube, vent valve, ROV and liquid vapor
separator (LVS), level sensors and passive side drain.

FUEL PUMP MODULE

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.
