System Operation
The pedestrian protection system is operational when the vehicle is traveling at speeds between approximately 20 km/h (12.4
mph) and 45 km/h (28 mph). A vehicle speed signal is received by the pedestrian protection system control module over the
high speed CAN bus.
The system is able to determine if contact is made with a pedestrian or another object, such as a traffic cone, using signals
from accelerometers mounted behind the front bumper. When the system determines contact is made with a pedestrian it fires
the actuators to lift the rear of the hood approximately 130 mm within 35 ms of the 'fire' signal.

When an impact condition is registered, the pedestrian protection system control module outputs an impact signal on the high
speed CAN bus. This signal is used by the RJB to initiate the hazard warning lamps. If this occurs, the hazard warning lamp switch is disabled for the remainder of the current ignition cycle.

If the pedestrian protection system control module detects a fault with the system, it outputs a message on the high speed
CAN bus to the instrument cluster message center. On receipt of this, the message center will display the message 'CHECK PEDESTRIAN SYSTEM'.

The pedestrian protection system control module also stores the VIN (vehicle identification number). If a new control module
is fitted to the vehicle the Jaguar approved diagnostic tool must be used to program the unit with the vehicles VIN.
When the vehicle is delivered from the factory the pedestrian protection system is in a 'safe' plant mode. Normal operating
mode should be activated using the Jaguar approved diagnostic tool during the Pre-Delivery Inspection (PDI) prior to delivery
to the customer. For additional information, refer to the PDI manual.

If any damage is caused to the front of the vehicle, be it cosmetic or structural, repairs must be carried out in line with the
processes contained in the workshop manual. Failure to carry out the correct repair process could compromise operation of the
pedestrian protection system. Refer to GTR for the latest information.

The vehicle must be left for 1 minute after disconnecting the battery before any work can be carried out on the pedestrian
protection system.

Failure Mode Detection

In service, if any fault is detected, or any part of the system is recognized as not being present, the message center displays
the warning 'Check Pedestrian System'.

The bonnet deployment actuators are non-serviceable components, and if they must be replaced due to a fault, or due to
having been deployed, or following any other accident, their barcode labels must be read and recorded in the service database
against the vehicle VIN for security purposes.

After deployment of the pedestrian protection system, the vehicle must be stopped as soon as it is safe to do so. The hazard
warning lamps will be activated and can only be switched off by pressing the engine START/STOP button to turn the engine off
and on again. A warning message 'CHECK PEDESTRIAN SYSTEM' will appear on the message center and the vehicle should be
transported to the nearest dealer/authorised repairer. The vehicle must not be driven when the bonnet has been deployed.


NOTE: If the warning message 'CHECK PEDESTRIAN SYSTEM' appears in the message center when the bonnet has not
been deployed, the vehicle should be taken to the nearest dealer/authorised repairer immediately. It can be driven.

If any significant damage occurs to the front bumper it should be inspected by a dealer/authorised repairer as soon as
possible.



CONTROL MODULE Component Description

The control module is mounted below the hood release lever behind the side trim in the left hand front footwell.

The deployment signal is received from the pedestrian protection system control module. The second-generation system
adopted for XF is all-new to Jaguar and, although similar, differs from that introduced on XK by having an accelerometer-based
sensing system rather than a contact-sensing system. The accelerometer-based system is supplied by Bosch. Mounted very
close to the skin of the bumper, it examines the characteristics of vibration waves caused by impact. Its response time is
quicker, because it does not rely on the front of the bumper being loaded. It uses the 'saved' time to make more complex
decisions, and so has fewer error states. The speed of vehicle and the length of the bonnet define the time available to get
the bonnet into its deployed and stabilized position. It is possible, therefore, to create a time-line counting back from the
predicted moment of head impact to the time when the deployment signals need to be sent. That in turn defines a time from
first contact to decision time.

metal surfaces are bolted together always interpose a suitable interface material such as weldable zinc rich primer, extruded
strip, or zinc tape.

Steam Cleaning

Due to the high pressure/temperature generated by steam cleaning equipment, there is a risk that certain adhesives and
corrosion prevention material may become softened or liquified.
Take care not to allow the steam jet to dwell on one area, and keep the nozzle at least 300mm from the panel surface.


CAUTION: Do not remove wax or lacquer from underbody areas during repairs.

Inspection During Maintenance Servicing

It is a requirement of the corrosion warranty that the vehicle is inspected for corrosion by a Jaguar Authorised Repairer during a
routine service, to ensure that the factory-applied protection remains effective.

Rectify any bodywork damage or evidence of corrosion found during inspection as soon as is practicable, both to minimise the
extent of the damage and to ensure the long term effectiveness of the factory-applied corrosion prevention treatment.

Underbody Protection Repairs

Whenever body repairs have been carried out, ensure that full sealing and corrosion protection treatments are reinstated. This
applies both to the damaged areas and also to areas where protection has been indirectly impaired, as a result either of
accident damage or repair operations.

Remove corrosion protection from the damaged areas before straightening or panel beating. This applies in particular to panels
coated with wax, PVC underbody sealer, sound deadening pads etc.


CAUTION: Do not use oxy-acetylene to remove corrosion prevention material. Large volumes of fumes and gases are
liberated by these materials when they burn.

The most common method of removal is by means of a hot air blower with an integral scraper. High temperatures can be
generated with this equipment which may cause fumes. Take care during its use.

Structural Adhesive


CAUTION: When separating a joint with metal to metal adhesive, it is important to avoid distortion. Heat gradually until
the bond weakens sufficiently to permit panel separation - do not apply excessive heat.


NOTE: When spot welding through metal to metal adhesive, take particular care to adjust the equipment setting to
ensure a suitable weld.

Metal to metal adhesive is applied to critical joint areas during factory assembly. The material used is a high temperature,
heat cured, nitrile phenolic which serves to bond two metal surfaces and also to seal the joint against ingress of dust,
moisture and fumes. This material is not suitable for service use and, during repair, should be substituted by an approved
structural adhesive. For panel specific information and to identify the areas of structural adhesive application in repair, refer to
the relevant sheet metal removal and installation procedure.

Expanding Foam Acoustic Seals

Expanding foam acoustic seals are used in various closed-sections of the body to improve vehicle refinement. The seals are
installed during the vehicle body manufacture and expand during the paint process up to ten times original size, thus locking
them into position. They are located such that they prevent noise accentuation along a section and reflect air borne noise
away from the cabin.

The seals have spilt functionality depending on location. The seals located at the base of the body pillars have a primary
function of preventing water ingress when wading. Their secondary function is to prevent noise and dust ingress.

The seal around the fuel filler has a primary function of preventing both fuel and water ingress. With a secondary function of
preventing noise and dust ingress.

The remaining seals primary function is to prevent noise accentuation along a section and reflect air borne noise away from the
cabin.

Another advantage of the seals is that they marginally increase the overall stiffness of the body and its structural performance
in case of a crash.
The seals are manufactured from an expandible polymer.

Replacing Expanding Foam Acoustic Seals

As paint oven temperatures used in a repair workshop are significantly lower than those that are used during manufacture of
the vehicle, (the temperatures are not sufficient to expand the foam), a different process is required to replicate the foam in
repair.

Seam Sealer

A heat cured, PVC based sealant is applied to specific joint seams during factory assembly. This material is not suitable for
service use and during repair and should be substituted by an approved seam sealer.


NOTE: Where seams are inaccessible following the reassembly or fitting of components, ensure that a paste-type seam
sealer is applied to such seams. Certain seams also become inaccessible after the completion of panel repairs. In such
instances apply seam sealer and paint before final assembly.

Apply seam sealers after the application of primer and before the application of top coat. The sealer must form a continuous
bead, with the profile of the bead dependent on the type of seam. If the seam sealer is applied with a brush take particular
care to maintain the required coverage of the seam.

Ensure that all accessible repair seams are sealed following a repair. Damage to a vehicle often flexes areas of the body
remote from the impact. As a result the seam sealer in these areas may be disturbed by subsequent straightening and repair
operations. Check all seams in the vicinity of the area undergoing repair for evidence of cracked seam sealer, then clean out as
required and apply fresh seam sealer using the following procedure:

Clean the affected seam and re-treat any exposed metal areas with a suitable etch phosphate primer.
Treat affected area with an etch-acid primer.
Apply appropriate seam sealer as necessary.
apply appropriate colour coat (and under body sealer as applicable).

Provided access is adequate, apply seam sealer to both sides of a repair joint. Where access is limited to one side only, (e.g.
box section), treat the affected box member with cavity wax.

Cavity Wax

After repairs, always re-treat these areas with an approved cavity wax. In addition, treat all interior surfaces which have been
disturbed during repairs whether they have been treated in production or not. This includes all box members, cavities and door
interiors.

Before wax injection, ensure that the cavity to be treated is free from any contamination or foreign matter. Where necessary,
clear out any debris.
Ensure that cavity wax is applied after the final paint process and before refitting any trim components.

During application ensure that the wax covers all flanges and seam areas and that it is adequately applied to all repaired
areas of both new and existing panels.

It should be noted that new panel assemblies and complete body shells are supplied without wax injection treatment. Ensure
that such treatment is carried out after repairs.
Effective cavity wax protection is vital. Always observe the following points:
Complete all paint refinish operations before wax application.
Check the spray pattern of injection equipment.
Mask all areas not to be waxed.
Remove body fixings, such as seat belt retractors, if contamination is at all likely.
Move door glasses to fully closed position before treating door interiors.
Treat body areas normally covered by trim before refitting items.
Check that body and door drain holes are clear after the protective wax has dried.
Keep all equipment clean, especially wax injection nozzles.

NOTE: The illustration may indicate either hand of the service panel, the opposite hand will be similar.
