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, carry out the test methods described below, alternatively check for diagnostic
trouble codes and refer to the relevant diagnostic trouble code index

and the safety belt buckle sensor. Based on this data, the RCM decides which level of airbag module deployment is required and forwards the information to the second area, the deployment handler.

The deployment handler evaluates the status of the seat track position sensor and safety belt buckle sensors before a decision
is made about which restraints should finally be deployed.

Data from the side crash sensors is used by the RCM in conjunction with acceleration data from the RCM internal accelerometer to make a deployment decision. The RCM processes the acceleration data and subject to an impact being of high enough severity, decides whether the side airbag module should be deployed.

On board testing of the airbag modules, front safety belt pretensioner firing circuits, warning indicator circuits and module
status (the crash and side impact sensors perform basic self-tests) is performed by the RCM together with the storing of fault codes.

The RCM drives the SRS indicator on the instrument pack via a CAN signal. If the warning lamp fails, a fault code is recorded and a warning tone is sounded in place of the lamp if a further fault occurs. It also provides a temporary back-up power supply
to operate the airbag modules in the event that in crash conditions, the battery supply is lost. In the event of a crash, it
records certain data which can be accessed via the diagnostic connector.

A safing sensor in the RCM provides confirmation of an impact to verify if airbag and pretensioner activation is necessary. A roll-over sensor monitors the lateral attitude of the vehicle. Various firing strategies are employed by the RCM to ensure that during an accident only the appropriate airbags and pretensioners are fired. The firing strategy used also depends on the
inputs from the safety belt switches and the occupant monitoring system.

An energy reserve in the RCM ensures there is always a minimum of 150 milliseconds of stored energy available if the power supply from the ignition switch is disrupted during a crash. The stored energy is sufficient to produce firing signals for the
driver airbag, the passenger airbag and the safety belt pretensioners.

When the ignition is switched on, the RCM performs a self-test and then performs cyclical monitoring of the system. If a fault is detected the RCM stores a related fault code and illuminates the airbag warning indicator. The faults can be retrieved by the recommended Jaguar diagnostic tool over the CAN bus. If a fault that could cause a false fire signal is detected, the RCM disables the respective firing circuit, and keeps it disabled during a crash event.

Clock Spring



The clockspring is installed on the steering column to provide the electrical interface between the fixed wiring harness of the
steering column and the components that rotate with the steering wheel, i.e. the driver airbag, the horn and the steering
wheel switch packs.

The clockspring consists of a plastic cassette which incorporates an outer cover fixed to the steering column and an inner rotor
which turns with the steering wheel. Four securing lugs attach the cover to the multifunction switch on the steering column.
The rotor is keyed to the steering wheel by a drive peg. A lug on the underside of the rotor operates the self-cancelling feature
of the turn signal indicator switch. A ribbon lead, threaded on rollers in the rotor, links two connectors on the cover to two
connectors on the rotor. Link leads for the driver airbag are installed in one of the connectors on the rotor.

To prevent damage to the ribbon lead, both the steering and the clockspring must be centralized when removing and installing
the clockspring or the steering wheel. The clockspring is centralized when the drive peg is at six o'clock and 50 - 100% of a
yellow wheel is visible in the viewing window.

Replacement clocksprings are fitted with a stopper, which locks the cover to the rotor, in the central position. The stopper must
be broken off when the replacement clockspring is installed.

occupant position and the crash severity. To reduce the risk of an airbag module induced injury to a driver that is positioned
close to the steering wheel, the airbag module deploys radially. It has a non-azide propellant that reduces particulates and
effluents. It consists of a two stage inflator with separate chambers for the two inflation stages, each being independently
activated by the RCM. It has two electrical connectors that are color coded and mechanically keyed to the respective connector on the inflator.

Passenger Airbag Module



The passenger airbag module is controlled by the RCM which chooses between single or dual stage deployment, depending on the occupant status and the crash severity. It consists of a two stage inflator with two airbag electrical connectors to
accommodate the two stage inflation.

The heated gas inflator consists of a high-pressure mix of clean air and hydrogen gas, triggered by two separate ignition
squibs. It produces a controlled generation of clean gas to rapidly fill the airbag. It is classified as a stored flammable gas
(not as an explosive) and as such, has less restrictive storage and transportation requirements. It produces a very clean burn
and almost no particulates and is almost free of any toxins, making disposal or recycling much easier. Drivers Airbag Module

There is a fault with the passenger airbag firing circuit(s).
The passenger airbag is deactivated with the passenger airbag deactivation switch (where fitted).
Required by passenger seat occupant monitoring (see below).

Passenger Airbag Deactivation Switch (All Except NAS)

The passenger airbag deactivation switch provides a method of manually disabling the passenger airbag. The switch is
installed in the front passenger end of the instrument panel and operated by the ignition key.

When the passenger airbag deactivation switch is operated, it changes a ground connection between two pins in the
connectors of the RCM. When the passenger airbag deactivation switch is selected to OFF, the RCM disables the passenger airbag and, if the front passenger seat is occupied, illuminates the passenger airbag deactivation indicator.

Occupant Detection System

There are two types of occupant monitoring:

In all markets except NAS & Australia, vehicles have an occupant detection sensor
In NAS markets, vehicles have an occupant classification system

For markets which have an occupant detection sensor, this has no interface with the restraints system and only provides the
belt reminder function.

For markets that have an occupant classification system, this provides the RCM with the occupancy status of the front passenger seat. The RCM uses this and the seat buckle status in the evaluation of the firing strategy for the passenger front airbag, side airbag, and pretensioner.

The occupant classification system can determine if the front passenger seat is unoccupied, occupied by a small person, or
occupied by a large person. The occupant classification system consists of:

A pressure pad, installed under the cushion of the front passenger seat, which is connected to a pressure sensor
A safety belt tension sensor, integrated into the anchor point of the front passenger safety belt
An occupant classification module, installed under the front passenger seat.

The pressure pad is a silicone filled bladder. Any load on the pressure pad is detected by the pressure sensor.

The safety belt tension sensor is a strain gauge that measures the load applied by the safety belt anchor to the anchor bolt.
The sensor is located in the lower safety belt anchor point.

General Information

Introduction Published: 11-May-2011

The body plays a significant role in the increasing trend of ever more rapidly changing model variants. The different customer
groups are strongly influenced by the design and shape of the body. At the same time the stability of the body plays the most
important part in ensuring passenger and driver safety. Lightweight construction, alternative materials, composite materials,
plastics and appropriate joining processes are all design features that characterise modern Jaguar vehicle bodies.

In terms of manufacturing technology, modern safety cell bodies can be produced almost without any problems. Jaguar
guarantee high quality standards by ensuring that mechanical strength properties are tried and tested in numerous computer
simulations, crash tests, by testing materials and by employing sophisticated manufacturing technologies. In the event of
repairs it is vital that the production quality standards are upheld. This requires a well-equipped workshop, and places
particular emphasis on the qualifications of the workshop technicians. Up-to-date knowledge of current manufacturing
technologies and continuous training on new repair methods and techniques are vital for high-quality body repairs. The model-
specific repair manuals and the general repair techniques provide valuable support when undertaking body repairs.

Always follow the repair instructions published in this manual. Failure to observe this instruction can result in serious
impairment of vehicle safety. All specified safety requirements must be met after the work has been carried out.

Vehicle design

The body

The XF adopts the latest generation steels, especially in the upper body – including high carbon steels, dual-phase,
hot-formed boron steels, and bake-hardened steels to form a vertical safety ‘ring’ around the occupant cell. As well as
combining strength with lightness, these steels improve corrosion resistance, by making best use of zinc and improving e-coat
paint flow – and new thinking means that in spite of their strength, the XF’s A and B-pillars are impressively slim, to the
benefit of both visibility and accessibility. Similarly, the lower sills are the first component on any Jaguar to use incredibly
strong, dual-phase DP600 steel.
The safety of the driver and the passengers is paramount for every body design. There are two key safety aspects in the body:
Safety passenger cell
Crumple zones

Safety passenger cell

Stable pillars, rocker panel and door profiles.
Side impact protection in the doors.
Doors are designed to open even in the event of extreme deformation.
Crumple zone

Dynamic absorption of deforming forces.
