Freelander Service Procedures
GENERAL INFORMATION
03-20
Disciplines
Switch off the ignition prior to making any connection
or disconnection in the system, to prevent electrical
surges caused by disconnecting 'live' connections
damaging electronic components.
Ensure hands and work surfaces are clean and free
of grease, swarf, etc. Grease collects dirt which can
cause electrical tracking (short-circuits) or high-
resistance contacts.
When handling printed circuit boards, treat with care
and hold by the edges only; note that some electronic
components are susceptible to body static.
Connectors should never be subjected to forced
removal or refit, especially inter-board connectors.
Damaged contacts can cause short-circuit and
open-circuit fault conditions.
Prior to commencing test, and periodically during a
test, touch a good vehicle body earth to discharge
static charge. Some electronic components are
vulnerable to the static electricity that may be
generated by the operator.
Grease for electrical connectors
Some under bonnet and under body connectors may
be protected against corrosion by the application of a
special grease during vehicle production. Should
connectors be disturbed in service, or repaired or
replaced, additional grease should be re-applied:
Part No. BAU 5811, available in 150 gm tubs.
NOTE: The use of greases other than BAU 5811
must be avoided as they can migrate into relays,
switches etc. contaminating the contacts and leading
to intermittent operation or failure.
Supplementary restraint system
precautions
General
The Supplementary Restraint System (SRS)
provides active protection for vehicle occupants in
the event of a serious collision. The system
components include airbags and pre-tensioner seat
belts which are automatically deployed when a
severe frontal crash condition is detected.
The SRS pyrotechnic components could be
potentially hazardous to the service engineer if not
handled correctly. The following guidelines are
intended to alert the service engineer to potential
sources of danger and emphasise the importance of
ensuring the integrity of SRS components fitted to
the vehicle.
In order to assure system integrity, it is essential that
the SRS system is regularly checked and maintained
so that it is ready for operation in the event of an
accident.
Where necessary, additional specific precautions are
detailed in the relevant sections of this Manual which
should be referred to prior to commencing repair
operations.
WARNING: Always follow the 'SRS Precautions'
and the correct procedures for working on SRS
components. Persons working on SRS systems
must be fully trained and have been issued with
copies of the Safety guidelines.
WARNING: It is imperative that before any work
is undertaken on the SRS system the appropriate
information is read thoroughly.
WARNING: The airbag module contains sodium
azide which is poisonous and extremely
flammable. Contact with water, acid or heavy
metals may produce harmful or explosive
compounds. Do not dismantle, incinerate or
bring into contact with electricity, before the unit
has been deployed.
WARNING: Always replace a seat belt assembly
that has withstood the strain of a severe vehicle
impact, or if the webbing shows signs of fraying.
WARNING: Always disconnect the vehicle
battery before carrying out any electric welding
on a vehicle fitted with an SRS system.
CAUTION: Do not expose an airbag module or
seat belt pre-tensioner to heat exceeding 85º C
(185º F).
