How To Use This Manual
General
To assist in the use of this Manual, it is divided into
sections and sub-sections. The section title is given
at the top of each page and the relevant sub-section
is given at the bottom.
There is a single contents section at the front of the
Manual, which is divided by section and sub-section.
Each section is numbered from page 1.
The individual items comprising repair operations are
to be followed in the sequence in which they appear.
Item numbers shown in illustrations are referred to in
the associated text.
Adjustment, Repair and Overhaul operations include
reference to Service tool numbers and the
associated illustration depicts the tool in use.
Adjustment and repair operations also include
reference to wear limits, relevant data, torque
figures, specialist information and useful assembly
details. Each adjustment or repair operation is given
a Service Repair Operation (SRO) number.
WARNINGS, CAUTIONS and NOTES have the
following meanings:
WARNING: Procedures which must be followed
precisely to avoid the possibility of injury.
CAUTION: Calls attention to procedures which
must be followed to avoid damage to
components.
NOTE: Gives helpful information.
References
References to the LH or RH side given in this Manual
are made when viewing the vehicle from the rear.
With the engine and gearbox assembly removed, the
crankshaft pulley end of the engine is referred to as
the front.
Operations covered in this Manual do not include
reference to testing the vehicle after repair. It is
essential that work is inspected and tested after
completion and if necessary a road test of the vehicle
is carried out. This is of particular importance where
safety related items are concerned.
Dimensions
The dimensions quoted are to design engineering
specification. Service limits are included where
applicable.Electrical Reference Library (ERL) and Circuit
Diagrams
The Electrical Reference Library (ERL) and Circuit
Diagrams are separate publications intended for use
by trained Land Rover technicians and should be
referred to when attempting to diagnose electrically
related concerns.
The ERL contains descriptions of how the circuits
operate, fuse details, earth point locations, and a
definitive guide to the attributes and location of every
connector on the vehicle.
The ERL is used in conjunction with the Circuit
Diagrams. Both publications are designed to support
all aspects of electrical fault diagnosis.
TESTBOOK (Fault Diagnostic Equipment)
Freelander is equipped with a number of electronic
control systems to provide optimum performance of
the vehicle's systems.
Diagnostic equipment (TESTBOOK/T4) is available
to assist with the fault diagnostic abilities of the
dealer workshop. In particular, the equipment can be
used to interrogate the Engine Control Module
(ECM) for diagnosis of emissions related faults which
may become evident by the illumination of the
Malfunction Indicator Lamp (MIL) in the instrument
pack. This feature is included in compliance with the
latest emissions legislation pertinent to a particular
market (e.g. EU3 for Europe, OBDII for North
America etc.).
This repair manual is produced as a reference
source to supplement Testbook/T4. When available,
the equipment should be used as the primary means
of fault diagnosis on electronically controlled
systems.
Features of TestbookT4 include:
lFully upgradable support for the technician
lStructured diagnostics to accommodate all skill
levels.
lTouch screen operation - Testbook only.
lDirect print out of screen information and test
results.

77-2-16 WELDING PROCEDURES
General Welding Precautions
General
For ease of reference, the diagrams on the following pages show only the type of weld used in repair where it varies
from that used in production.
The replacement welds in the welding diagrams are denoted by the following symbols:
a = Single/Multiple thickness plug welds
b = MIG seam weld
When carrying out welding operations the following criteria must be observed:
lWhere resistance spot welds have been used in production, these must be reproduced with new spot welds in
replacement where possible. All such reproduction spot welds must be spaced 30 mm (1.181) apart;
lWhen spot welding, it is recommended that test coupons of the same metal gauges and materials are produced
to carry out peel tests to ensure that welding equipment being used can produce a satisfactory joint. Plug welds
must be used if a satisfactory spot weld cannot be produced;
lThe electrode arms on hand-held spot welding guns must not exceed 300 mm (11.811) in length;
lSingle-side spot welding is not acceptable;
lBrazing and gas welding are not acceptable EXCEPT where they have been specified in production;
lWhere 3 metal thicknesses or more are to be welded together it is imperative to use MIG plug welds to ensure
joint strength;
lMIG plug welds must be used in repair joints where there is no access for a resistance spot welder. To replace
each production spot weld, an 8 mm (0.314) approx hole must be drilled and/or punched, and a MIG plug weld
then made in its place. The number of plug welds must match exactly the number of spot welds which have been
removed;
lWhere holes are left in an existing panel after removal of the spot welds, a single MIG plug weld will be made in
each hole as appropriate.
Electronic Control Units
The electronic control units (ECU) fitted to vehicles make it advisable to follow suitable precautions prior to carrying
out welding repair operations. Harsh conditions of heat and vibration may be generated during these operations which
could cause damage to the units.
In particular, it is essential to follow the appropriate precautions when disconnecting or removing the airbag DCU.
Equipment
Prior to commencing any test procedure on the vehicle, ensure that the relevant test equipment is working correctly
and any harness or connectors are in good condition. This particularly applies to electronic control units.
