Wheels and Tires - Wheels and Tires - Overview
Description and Operation

OVERVIEW Published: 25-May-2012

A number of alloy wheel designs are available ranging from 17 to 20 inch in diameter. A Tire Pressure Monitoring System
(TPMS) is used to monitor the air pressure in each tire and inform the driver if the pressure falls below predetermined
thresholds.

All wheels are of cast construction in aluminum alloy with the choice of wheel design dependant on the vehicle trim level and
engine derivative.

On normally aspirated petrol models and all diesel models a 4J X 18 inch temporary spare wheel is supplied as standard,
supercharged petrol models are supplied with a 4Jx19 inch temporary spare wheel. In some major European markets an Instant
Mobility System is offered as an alternative to the spare wheel. The Instant Mobility System is capable of providing a
temporary repair and tire inflation to a puncture of up to 6mm in diameter in the tread area of the tire. A puncture in the tire
wall cannot be repaired using the system.
The vehicle jack and accessories are stored in the spare wheel-well in the luggage compartment.

Tire Changing

WARNINGS:


Tires must be inflated to the recommended pressures when the tires are cold (ambient temperature) only. Refer to label
on the 'B' pillar for recommended tire pressures. If the tires have been subjected to use or exposed to direct sunlight, move
the vehicle into a shaded position and allow the tires to cool before checking or adjusting the pressures.


Valve stem seal, washer nut, valve core and cap should be replaced at every tire change. Valve stem seal, washer and
nut must be replaced if the valve retention nut is loosened. Sensor units and nuts must be fitted using correct torque figures
and associated profile. Damage to the vehicle and consequently injury to the vehicle's occupants may result if these
instructions are not adhered to.


NOTE: The TPMS valve should be serviced using the suitable service kit, each time the tyre is dismounted, to ensure an
air tight seal. Attention should be made to the detail of fitting this kit.

Vehicles fitted with TPMS can be visually identified by an external metal locknut and valve of the tire pressure sensor on the
road wheels. Vehicles without TPMS will have rubber tire valve.
www.JagDocs.com

The warning indications to the driver are common on all vehicles fitted with TPMS. The driver is alerted to system warnings by
a low tire pressure warning indicator in the instrument cluster and an applicable text message in the message centre.

The TPMS module passes system status information to the instrument cluster on the medium speed CAN bus. The instrument
cluster converts this data into illumination of the warning indicator and the display of an appropriate message.
When the ignition is switched on, the warning indicator is illuminated for 3 seconds for a bulb check.


NOTE: If the vehicle is not fitted with the TPMS, the warning indicator will not illuminate.

The instrument cluster checks, within the 3 second bulb check period, for a CAN bus message from the TPMS. During this time
the TPMS performs internal tests and CAN bus initialization. The warning indicator will be extinguished if the TPMS module
does not issue a fault message or tire pressure warning message.

If a TPMS fault warning message is detected by the instrument cluster at ignition on, the warning indicator will flash for 72
seconds after the 3 second bulb check period and then remain permanently illuminated.

If a tire pressure warning message is detected by the instrument cluster at ignition on, the warning indicator will extinguish
briefly after the 3 second bulb check period, before re-illuminating to indicate a tire pressure warning.
The following table shows the warning indicator functionality for given events:

18 Pinion 19 Steering gear rack bar 20 Valve sleeve The valve unit is an integral part of the steering gear. The principle function of the valve unit is to provide power assistance
(i.e. when parking) to optimize the effort required to turn the steering wheel.

The pinion housing of the valve is an integral part of the main steering gear casting. The pinion housing has four machined
ports which provide connections for pressure feed from the power steering pump, return fluid to the reservoir and pressure
feeds to each side of the cylinder piston.

The valve unit comprises an outer sleeve, an input shaft, a torsion bar and a pinion shaft. The valve unit is co-axial with the
pinion shaft which is connected to the steering column via the input shaft. The valve unit components are located in the
steering gear pinion housing which is sealed with a cap.

The outer sleeve is located in the main bore of the pinion housing. Three annular grooves are machined on its outer diameter.
PTFE (polytetrafluoroethylene) rings are located between the grooves and seal against the bore of the pinion housing. Holes
are drilled radially in each annular groove through the wall of the sleeve. The bore of the outer sleeve is machined to accept
the input shaft. Six equally spaced slots are machined in the bore of the sleeve. The ends of the slots are closed and do not
continue to the end of the outer sleeve. The radial holes in the outer sleeve are drilled into each slot.

The input shaft has two machined flats at its outer end which allow for the attachment of the steering column intermediate
shaft yoke. The flats ensure that the intermediate shaft is fitted in the correct position. The inner end of the input shaft forms
a dog-tooth which mates with a slot in the pinion shaft. The fit of the dog-tooth in the slot allows a small amount of relative
rotation between the input shaft and the pinion shaft before the dog-tooth contacts the wall of the slot. This ensures that, if
the power assistance fails, the steering can be operated manually without over stressing the torsion bar. The central portion of
the input shaft has equally spaced longitudinal slots machined in its circumference. The slots are arranged alternately around
the input shaft.

The torsion bar is fitted inside the input shaft and is an interference fit in the pinion shaft. The torsion bar is connected to the
input shaft by a drive pin. The torsion bar is machined to a smaller diameter in its central section. The smaller diameter allows
the torsion bar to twist in response to torque applied from the steering wheel in relation to the grip of the tyres on the road
surface.

The pinion shaft has machined teeth on its central diameter which mate with teeth on the steering gear rack. A slot, machined
in the upper end of the pinion shaft mates with the dog-tooth on the input shaft. The pinion shaft locates in the pinion
housing and rotates on ball and roller bearings.

Servotronic Valve

The Servotronic transducer valve is located in a port in the side of the steering gear valve housing. The valve is sealed in the
housing with an O-ring seal and is secured with two long screws into threaded holes in the housing. The Servotronic valve is a
transducer controlled valve which responds to control signals supplied from Servotronic software in the instrument cluster.

The Servotronic valve determines the hydraulic reaction at the steering gear rotary valve and controls the input torque required
to turn the steering wheel. The Servotronic system allows the steering to be turned with the optimum effort when the vehicle
is stationary or manoeuvred at slow speed. The hydraulic reaction changes proportional to the vehicle speed, with the required
steering effort increasing as the vehicle moves faster. At high speeds, the Servotronic system provides the driver with a good
feedback through the steering providing precise steering and improved stability.

The instrument cluster receives road speed signals from the ABS module and calculates the correct controlling signal for the Servotronic valve. The Servotronic software within the instrument cluster has a diagnostic capability which allows a Jaguar
approved diagnostic system to check the tune of the steering and retrieve fault codes relating to the Servotronic valve. Two
fault codes are stored relating to the valve for positive connection short to ground or battery and negative connection short to
ground or battery.

The Servotronic software within the instrument cluster also contains a number of steering maps which are selected via the car
configuration file depending on the vehicle model and tire fitment.

If a failure of the Servotronic valve or software occurs, the system will suspend Servotronic assistance and only a default level
of assistance will be available. Fault codes relating to the fault are stored in the instrument cluster. No warning lamps are
illuminated and the driver may be aware of the steering being 'heavier' than usual.

6. Adaptive Speed Control Indicator
The adaptive speed control system is controlled by the adaptive speed control module. Operation of the SET +/- switches on
the steering wheel will activate the system. Operation of the switches is detected by the adaptive speed control module. The
module issues a high speed CAN message to the instrument cluster which illuminates the adaptive speed control indicator, when the system is in 'follow mode', in an amber color and displays a 'SETSPEED XXX MPH / KM/H' message in the message
center. The indicator is illuminated in an amber color for a 3 second indicator check when the ignition is switched on.
7. Anti-lock Braking System (ABS) Warning Indicator

The ABS warning indicator is controlled by the ABS module. If a fault in the ABS system is detected by the ABS module, the module issues a high speed CAN message to the instrument cluster to illuminate the ABS warning indicator in an amber color and display the message 'ABS FAULT' in the instrument cluster. The indicator is illuminated in an amber color for a 3 second
indicator check when the ignition is switched on. If a fault is present when the ignition is on, the bulb will remain illuminated
after the 3 second indicator check period.
NOTES:


The 'ABS FAULT' message is not displayed in NAS markets).


If both the ABS warning indicator and the brake warning indicator illuminate simultaneously, a major fault in the brake system will have occurred.

On NAS vehicles, the ABS warning indicator is also used for parking brake operation. The NAS warning indicator does not have 'ABS' on the icon and will function as described previously for the parking brake operation of the brake warning indicator.
8. Engine Malfunction Indicator Lamp (MIL)

The MIL warning indicator is controlled by the ECM and illuminated by the instrument cluster on receipt of a message on the high speed CAN bus from the ECM. The indicator is illuminated in an amber color for a 3 second indicator check when the ignition is switched on.

If the MIL remains illuminated after the engine is started or illuminates when driving, a fault is present and must be
investigated at the earliest opportunity. Illumination of the MIL warning indicator alerts the driver to an OBD (on-board
diagnostic) fault which will cause excessive emissions output. This may relate to either an engine management system fault or
a transmission.
9. Tire Pressure Monitoring System (TPMS) Warning Indicator

The TPMS warning indicator is illuminated by the instrument cluster on receipt of a medium speed CAN message from the TPMS module. The indicator is illuminated in an amber color for a 3 second indicator check when the ignition is switched on.

If the indicator illuminates and is accompanied by the message 'TYRE PRESSURE SYSTEM FAULT' in the message center, then a
TPMS fault has occurred. If the indicator illuminates and accompanied by a different message, then a low tire pressure has
been detected, a spare wheel has been fitted or a TPMS sensor has failed.
10. Airbag Warning Indicator

The airbag warning indicator is controlled by the instrument cluster. The indicator is illuminated in an amber color for the 3
second indicator check when the ignition is switched on. The indicator remains illuminated after the 3 second period has
expired until the instrument cluster receives a turn off message on the high speed CAN bus from the RCM (restraints control module).
11. Front Fog Lamp Indicator

The green colored front fog lamp indicator is controlled by the CJB and illuminated by the instrument cluster on receipt of a front fog lamp on message on the medium speed CAN bus from the CJB. The indicator is illuminated for as long as the front fog lamps are active. The front fog lamp indicator is not subject to the 3 second indicator check when the ignition is switched
on.
12. Dynamic Stability Control (DSC) Indicator

The DSC warning lamp is controlled by the ABS module and illuminated by the instrument cluster in response to messages received on the high speed CAN bus. The indicator is illuminated in an amber color for the 3 second indicator check when the ignition is switched on. The DSC warning indicator, are permanently illuminated in an amber color if the instrument cluster
receives a high speed CAN message from the ABS module relating to one of the following faults:
Traction control fault
Yaw control fault
Engine drag torque control fault
Panic Brake Assist (PBA) fault
Signal missing relating to either traction control active, yaw control active or DSC switch input.

The above faults will also generate an applicable DSC and ABS warning message in the message center. The DSC warning
indicator will flash at 2 Hz for if the traction control or yaw control is active when the DSC system is enabled. If the DSC
system is switched off, the warning indicator will be permanently illuminated until the DSC system is subsequently
re-activated.

13. Safety Belt Warning Indicator

The safety belt warning indicator operates for both the driver and passenger safety belts. The warning indicator is controlled by

CAUTION: When probing connectors to take measurements in the course of the pinpoint tests, use the adaptor kit, part
number 3548-1358-00
NOTES:


If the control module or a component 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/component.


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 extra 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 and
with a current calibration certificate. When testing resistance, always take the resistance of the DMM leads into account.


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


If DTCs are recorded and, after performing the pinpoint tests, a fault is not present, an intermittent concern may be the
cause. Always check for loose connections and corroded terminals.
