Jacking and Lifting - Jacking
Description and Operation

Safety Precautions Published: 11-May-2011

WARNING: The jack provided with the vehicle is intended to be used in an emergency for changing a deflated tire. To
avoid damage to the vehicle, never use the jack to raise the vehicle for any other purpose. Refer to the Driver Handbook when
using the jack supplied with the vehicle. Failure to follow these instructions may result in personal injury.
The following safety precautions must be observed when raising the vehicle to carry out service operations:
Never rely on a jack alone to support a vehicle. Always use suitable vehicle stands to provide rigid support.
When working beneath a vehicle, whenever possible use a vehicle hoist instead of a jack and vehicle stands.
Make sure that the vehicle is standing on firm, level ground before using a jack.
Do not rely on the parking brake alone; chock the wheels and put the automatic transmission into Park if possible.
Check that any lifting equipment used has adequate capacity for the load being lifted and is in correct working order.

Vehicle Support Points



Vehicle Recovery


NOTE: Prior to vehicle recovery, make sure the vehicle keys are available and the security system is disarmed.

Vehicle recovery methods are:

By flat-bed transporter.
By rear suspended tow.
By rear suspended tow.
Transporter or Trailer Recovery



When the vehicle is being recovered by transporter or trailer:

The parking brake must be applied and the wheels chocked.
The gear selector lever must be in Neutral. Do not select Park on automatic transmission vehicles, as the parking lock
mechanism may be damaged by the forward and backward rocking motion of the vehicle.
The vehicle must be securely tied down to the transporter or trailer.

Noise, Vibration and Harshness - Noise, Vibration and Harshness (NVH)
Diagnosis and Testing

Principle of Operation

For a detailed description of Noise, Vibration and Harshness issues, refer to the Description and Operation section of the
workshop manual.
REFER to: Noise, Vibration and Harshness (NVH) (100-04 Noise, Vibration and Harshness, Description and Operation).
Inspection and Verification

1. Verify the customer's concerns by operating the vehicle to duplicate the condition.

2. Visually inspect the vehicle to determine any obvious cause(s) of the concern(s).

3. If the inspection reveals obvious causes that can be readily identified, repair as necessary.
4. If the concern(s) remains after the inspection, determine the symptom(s) and refer to the Symptom Chart.

How To Use This Diagnostic Procedure Section

Noise, vibration and harshness (NVH) concerns have become more important as vehicles have become more sensitive to
these vibrations. This section is designed as an aid to identifying these situations
The section provides diagnostic procedures based on symptoms. If the condition occurs at high speed, for instance, the
most likely place to start is under High Speed Shake
The road test procedure will tell how to sort the conditions into categories and how to tell a vibration from a shake
A series of Road Test Quick Checks is provided to make sure that a cause is either pinpointed or eliminated
Name the condition, proceed to the appropriate section and locate the correct diagnosis. When the condition is
identified, the job is partly done
Follow the diagnostic procedure as outlined
Quick Checks are described within the step, while more involved tests and adjustments are outlined in General
Procedures
Always follow each step exactly and make notes to recall important findings later

Customer Interview

The road test and customer interview (if available) provide information that will help identify the concerns and will provide
direction to the correct starting point for diagnosis.

Identify the Condition
NVH problems usually occur in a number of areas:
tires
engine accessories
suspension
driveline
air leakage (wind noise)
squeaks and rattles
heating ventilation and air conditioning (HVAC)
electrical (e.g. motor noise)
transmission
engine

It is important, therefore, that an NVH concern be isolated into its specific area(s) as soon as possible. The easiest and
quickest way to do this is to carry out the Road Test as outlined.

Noise Diagnostic Procedure

Non-Axle Noise

The five most important sources of non-axle noise are exhaust, tires, roof racks, trim and mouldings, and transmission.

Therefore, make sure that none of the following conditions are the cause of the noise before proceeding with a driveline tear
down and diagnosis.

Under certain conditions, the pitch of the exhaust may sound very much like gear noise. At other times, it can be
mistaken for a wheel bearing rumble
Tires, especially snow tires, can have a high pitched tread whine or roar, similar to gear noise. Radial tires, to some
degree, have this characteristic. Also, any non-standard tire with an unusual tread construction may emit a roar or
whine type noise
Trim and mouldings can also cause whistling or a whining noise
Clunk may be a metallic noise heard when the automatic transmission is engaged in reverse or drive, or it may occur
when the throttle is applied or released. It is caused by backlash somewhere in the driveline
Bearing rumble sounds like marbles being tumbled. This condition is usually caused by a damaged wheel bearing

Tire Pressure Monitoring System (TPMS) System Operation

The controlling software for the Tire Pressure Monitoring System (TPMS) is located within a Tire Pressure Monitoring System
Module. The software detects the following:

When the tire pressure is below the recommended low pressure value - under inflated tire.
The location of the tire on the vehicle that is below the recommended pressure.
Malfunction warning.

The TPMS system comprises:

Tire pressure monitoring system module located below the right-hand front seat.
Tire pressure receiver located near the gear shifter within the floor console.
Two front initiators positioned forward of the wheels and behind the fender splash shields.
Two rear initiators positioned rearward of the wheels and assembled on dedicated brackets located behind the fender
splash shields.
Four sensors, each sensor is integral with a tire valve and located within the tire; the space saver spare wheel is not
fitted with a sensor.

The four initiators are hard wired to the TPMS module. The initiators transmit 125 KHz Low Frequency (LF) signals to the tire
pressure sensors which respond by modifying the mode status within the Radio Frequency (RF) transmission. The 315 or 433
MHz RF signals are detected by the tire pressure receiver which is connected directly to the TPMS module. The received RF
signals from the tire pressure sensors are passed to the TPMS module and contain identification, pressure, temperature and
acceleration information for each wheel and tire.

The TPMS module communicates with the instrument cluster via the medium speed CAN bus to provide the driver with
appropriate warnings. The TPMS module also indicates status or failure of the TPMS or components.

Tire Location and Identification

The TPMS can identify the position of the wheels on the vehicle and assign a received tire pressure sensor identification to a
specific position on the vehicle, for example front left, front right, rear left and rear right. This feature is required because of
the different pressure targets and threshold that could exist between the front and rear tires.

The wheel location is performed automatically by the TPMS module using an 'auto-location' function. This function is fully
automatic and requires no input from the driver. The TPMS module automatically re-learns the position of the wheels on the
vehicle if the tire pressure sensors are replaced or the wheel positions on the vehicle are changed.
The TPMS software can automatically detect, under all operating conditions, the following:
one or more new tire pressure sensors have been fitted
one or more tire pressure sensors have stopped transmitting
TPMS module can reject identifications from tire pressure sensors which do not belong to the vehicle
two 'running' wheels on the vehicle have changed positions.

If a new tire pressure sensor is fitted on any 'running' wheel, the module can learn the new sensor identification automatically
through the tire learn and location process.

The tire-learn and location process is ready to commence when the vehicle has been stationary or traveling at less than 12
mph (20 km/h) for 15 minutes. This is known as 'parking mode'. The learn/locate process requires the vehicle to be driven at
speeds of more than 12 mph (20 km/h) for 15 minutes. If the vehicle speed reduces to below 12 mph (20 km/h), the learn
process timer is suspended until the vehicle speed increases to more than 12 mph (20 km/h), after which time the timer is
resumed. If the vehicle speed remains below 12 mph (20 km/h) for more than 15 minutes, the timer is set to zero and process
starts again.

Low Pressure Monitoring

The tire low pressure sensor transmits by RF (315 MHz or 433 MHz depending on market) signal. These signals contain data
which corresponds to tire low pressure sensor identification, tire pressure, tire temperature, acceleration and tire low pressure
sensor mode.

Each time the vehicle is driven, the tire pressure monitoring system module activates each LF antenna in turn. The
corresponding tire low pressure sensor detects the LF signal and responds by modifying the mode status within the RF
transmission.

The system enters 'parking mode' after the vehicle speed has been less than 20 km/h (12.5 miles/h) for 12 minutes. In parking
mode the tire low pressure sensors transmit a coded signal to the tire pressure monitoring system module once every 13
hours. If the tire pressure decreases by more than 0.06 bar (1 lbf/in²) the tire low pressure sensor will transmit more often as
pressure is lost.

As each wheel responds to the LF signal from the tire pressure monitoring system module, it is assigned a position on the
vehicle and is monitored for the remainder of that drive cycle in that position.

Description and Operation



JAGUARDRIVE CONTROL OPERATION

Engine Management System System Operation

The Engine Management System (EMS) varies the accelerator pedal maps to change the amount of torque per percentage of
pedal travel. The EMS can also change the accelerator pedal response to control the allowed torque change relative to the
speed of pedal travel.

Each driving mode uses a combination of operating parameters for each sub-system. Changing between driving modes initiates
a different set of operating characteristics, which will be noticeable to the driver. The driver will notice differences in engine
response when, for example, the accelerator pedal is held in a constant position and the driving mode is changed from Winter
to Dynamic, the driver will notice the torque and engine speed increase. Similarly, if the mode is changed from Normal or
Dynamic to Winter the driver will notice a reduction in torque and engine speed.


NOTE: The change in torque and engine speed can take approximately 30 seconds and care must be taken not to confuse
the JaguarDrive Control system operation with an EMS fault.
Transmission Control

The TCM (transmission control module) changes the shift maps for the JaguarDrive Control mode selected. This changes the
shift points providing early or late upshifts and downshifts. For example, on slippery surfaces in Winter mode the transmission
will select 2nd gear for starting from a standstill on a flat surface to minimize wheel slip.
Anti-lock Braking System Control

The ABS (anti-lock brake system) module controls several vehicle functions and adjusts the operating parameters of these
functions to optimize the selected JaguarDrive Control mode. Traction control uses different slip/acceleration thresholds to
improve traction and vehicle composure. For example, the system sensitivity is increased on slippery surfaces to reduce wheel
spin.

If TracDSC is selected or DSC is switched off, then subsequently the JaguarDrive Control mode is changed, DSC is automatically
switched back on (or to TracDSC for Dynamic mode).

The stability control uses different threshold values for the selected mode, reducing the requirement for the driver to change
the DSC system mode for optimum performance in various driving scenarios.
Incorrect Mode Usage

Selection of an inappropriate mode is discouraged in the following ways:

The active mode icon is continually displayed in the instrument cluster message center
In any special mode, when the ignition has been in the off position continuously for more than 6 hours, the JaguarDrive
Control system defaults to the special modes off (DSC on).

Selection of an inappropriate mode for the conditions will not endanger the driver or immediately cause damage to the vehicle.
Continued use of an inappropriate mode may reduce the life of some components. The driver may notice a different vehicle
response, with the engine and transmission responses being different than in the special modes off.
Driver Information

The instrument cluster contains a message center, which displays vehicle information to the driver. The message center
contains the JaguarDrive Control mode icons, which display the currently selected mode. If no symbol is displayed, no special
mode is selected and the system is in special modes off.

Any required changes to the subsystems are also passed to the driver in the form of warning illumination in the instrument
cluster or appropriate messages in the message center, DSC off for example.

In Dynamic mode when the transmission is in manual mode, the gear information is displayed in amber when the appropriate
engine speed is reached for optimum sporty change point.

DIAGNOSTICS

JaguarDrive Control relies on the correct functionality of the sub-systems. If one of the sub-systems develops a fault, the
JaguarDrive Control system will not function, even though the fault is not in the JaguarDrive Control system.

The JaguarDrive Selector module and rotary control should only be investigated if there are no apparent faults in any of the
sub-systems. If a fault in a sub-system is subsequently corrected, the JaguarDrive Control system will function normally after
an ignition on and off cycle.

JAGUARDRIVE CONTROL DESCRIPTION Component Description



Item Description 1 Winter mode button 2 DSC/TracDSC mode button 3 ASL (automatic speed limiter) - Reference only, not part of JaguarDrive system 4 Dynamic mode (Supercharged models only) The system is controlled by buttons adjacent to the JaguarDrive Selector located on the floor console. The buttons allow the
selection of one of the following 3 modes:

Special modes off
Winter mode
Dynamic mode (Supercharged models only).
The instrument cluster will display the selected JaguarDrive Control mode in the message center.

The JaguarDrive Control system uses a combination of a number of vehicle sub-systems to achieve the required vehicle
characteristics for the mode selected. The following sub-systems make up the JaguarDrive Control system:

The Engine Management System (EMS)
Automatic transmission
Brake system.

The JaguarDrive Control software is stored in the JaguarDrive Selector module located below the JaguarDrive selector. The
module detects the selection made using the buttons and transmits a signal on the high speed CAN bus, which is received by each of the sub-system control modules.

Each of the affected sub-system control modules contain software, which applies the correct operating parameters to their
controlled system for the JaguarDrive Control mode selection made.

Each sub-system control module also provides a feedback for the selected mode so that the JaguarDrive Control software can
check that all systems have changed to the correct operating parameters.


NOTE: The JaguarDrive Control system is a co-ordinating system only. It CANNOT generate a fault in one of the
participating sub-systems. All participating sub-systems should be FULLY diagnosed before assuming a fault with JaguarDrive
Control. Replacing the JaguarDrive Selector module should not be done until all other options have been exhausted. JAGUARDRIVE CONTROLS
