INFORMATION BODY REPAIRS
Body shells are of riveted, bolted and welded
construction and are bolted to the chassis frame.
It is essential that design dimensions and strength are
restored in accident rectification. It is important that
neither structural weakness nor excessive local
stiffness are introduced into the vehicle during body or
chassis repair.
Repairs usually involve a combination of operations
ranging from straightening procedures to renewal of
either individual panels or panel assemblies. The
repairer will determine the repair method and this
decision will take into account a balance of economics
between labour and material costs and the availability
of repair facilities in both equipment and skills. It may
also involve considerations of vehicles down-time,
replacement vehicle availability and repair turn-around
time.
It is expected that a repairer will select the best and
most economic repair method possible, making use of
the facilities available. The instructions given are
intended to assist a skilled body repairer by expanding
approved procedures for panel replacement with the
objective of restoring the vehicle to a safe running
condition and effecting a repair which is visually
acceptable and which, even to the experienced eye,
does not advertise the fact that it has been damaged.
This does not necessarily mean that the repaired
vehicle will be identical in all respects with original
factory build. Repair facilities cannot always duplicate
methods of construction used during production.
The panel repairs shown in this section are all based
on a 110 Station Wagon. Therefore all illustrations
and text relate only to this model. Although certain
areas of the vehicle, such as the front end, are
relevant to all models.
Operations covered in this Manual do not include
reference to testing the vehicle after repair. It is
essential that work is inspected and suspension
geometry checked after completion and if necessary a
road test of the vehicle is carried out, particularly
where safety related items are concerned.Where major units have been disconnected or
removed, it is necessary to ensure that fluid levels are
checked and topped up when necessary. It is also
necessary to ensure that the repaired vehicle is in a
roadworthy condition in respect of tyre pressures,
lights, washer fluid etc.
Body repairs often involve the removal of mechanical
and electrical units as well as associated wiring.
Where this is necessary use the relevant section in
this manual.
Taking into consideration the differences in body
styles, steering and suspension systems as well as
engine and suspension layouts, the location of the
following components as applicable to a particular
vehicle is critical:
Front suspension upper damper
mountings.
Front suspension or sub frame mountings.
Engine mountings on RH and LH chassis
longitudinals.
Rear suspension upper damper mountings.
Rear suspension mountings or lower
pivots.
Steering rack mountings.
Additional points which can be used to check
alignment and assembly are:
Inner holes in crossmember - side - main
floor.
Holes in valance front assembly.
Body to chassis mounting holes.
Holes in rear floor.
Holes in rear lower panels or extension
rear floor.
Fuel tank mountings.
Apertures for windscreen, backlight, bonnet and doors
can be checked by offering up an undamaged
component as a gauge and also by measuring known
dimensions.See BODY DIMENSIONS section.

SEALING AND CORROSION PROTECTION Stone Chip Resistant Paint/Primer
Re-treat all areas protected with factory-applied
anti-chip primer with suitable approved material in
repair.
Inspections during Maintenance Servicing
It is a requirement of the Land Rover Corrosion
Warranty that the vehicle body is checked for
corrosion by an authorised Land Rover dealer at least
once a year, to ensure that the factory-applied
protection remains effective.
Service Job Sheets include the following operations to
check bodywork for corrosion:
With the vehicle on a lift, carry out visual
check of underbody sealer for damage.
With the vehicle lowered, inspect exterior
paintwork for damage and body panels for
corrosion.
NOTE: Wash the vehicle and ensure that it
is free from deposits prior to inspection. It
is part of the owner’s responsibility to
ensure that the vehicle is kept free of
accumulations of mud which could accelerate the
onset of corrosion. The Dealer MUST wash the
vehicle prior to inspection of bodywork if the
customer has offered it in a dirty condition, and
pay special attention to areas where access is
difficult.
NOTE: The checks described above are
intended to be visual only. It is not
intended that the operator should remove
trim panels, finishers, rubbing strips or sound
deadening materials when checking the vehicle
for corrosion and paint damage.
With the vehicle on a lift, and using an inspection or
spot lamp, visually check for the following:
Corrosion damage and damaged
paintwork, condition of underbody sealer
on front and rear lower panels, sills and
wheel arches.
Damage to underbody sealer on main floor
and chassis members. Corrosion in areas
adjacent to suspension mountings and fuel
tank fixings.
NOTE: The presence of small blisters in
PVC underbody sealer is acceptable,
providing they do not expose bare metal.
Special attention must be paid to signs of damage
caused to panels or corrosion material by incorrect
jack positioning.
It is essential to follow the correct jacking and lifting
procedures.See GENERAL INFORMATION DATA,
Information section.
With the vehicle lowered, visually check for evidence
of damage and corrosion on all painted areas, in
particular the following:
Front edge of bonnet.
Visible flanges in engine compartment and
boot.
Lower body and door panels.
Where bodywork damage or evidence of corrosion is
found during inspection, rectify this 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 protection treatment. Where
the cost of rectification work is the owner’s
responsibility, the Dealer must advise the owner and
endorse the relevant documentation accordingly.
Where corrosion has become evident and is
emanating from beneath a removable component
(e.g. trim panel, window glass, seat etc.), remove the
component as required to permit effective rectification.

DESCRIPTION AND OPERATION ANTI-THEFT ALARM - FROM 02MY
The alarm and immobilisation system on 2002MY Defender is similar to that used on Discovery Series I (LJ)
models from 1996MY. The alarm system comprises the anti-theft alarm ECU, bonnet and door switches and a
volumetric sensor.
Anti-Theft Alarm ECU
The anti-theft alarm ECU is located behind the instrument pack and receives a permanent battery supply via fuses
6 and 7 in the under seat fuse box. The ECU also receives a battery supply via the ignition switch position II and
fuse 1 in the passenger compartment fuse box. The ECU is connected to the various supporting components by
two harness connectors.
The ECU controls the alarm system (perimetric and volumetric security), CDL system, engine immobilisation
system (Td5 only) and various other vehicle functions including direction indicators and interior lamps.
The anti-theft alarm ECU incorporates an RF receiver and antenna for reception of RF signals from the remote
handset for locking and alarm arming. The antenna is unterminated at one end, and for optimum performance the
antenna must not be wound around adjoining harnesses.
The anti-theft alarm ECU operates at one of two frequencies which are identified by a label on the unit. The
frequencies are:
433 MHz - Europe, Gulf States, South Africa
315 MHz - North America, South East Asia, Japan, Australia.
The anti-theft alarm ECU also incorporates an integral inertia switch. In the event of an impact of sufficient severity
to trigger the inertia switch when the ignition is on, the ECU will unlock all doors and operate the hazard warning
lamps. The ECU will remain in this condition for a pre-programmed period of 2 minutes. To reinstate CDL
functionality and to deactivate the hazard warning lamps, the ignition should be turned off and then on after the 2
minute timer has expired.
NOTE: There is a separate inertia switch for fuel cut off.
