Waste Management
One of the major ways that pollution can be reduced
is by the careful handling, storage and disposal of all
waste materials that occur on sites. Legislation
makes it illegal to dispose of waste materials other
than to licensed waste carriers and disposal sites.
This means that it is necessary to not only know what
the waste materials are, but also to have the
necessary documentation and licenses.
Handling and storage of waste
Ensure that waste materials are not poured down the
drain or onto soils. They should be stored in such a
way as to prevent the escape of material to land,
water or air.
They must also be segregated into different types of
waste e.g. oil, metals, batteries, used vehicle
components. This will prevent any reaction between
different materials and assist in disposal.
Disposal of waste
Disposal of waste materials must only be to waste
carriers who are licensed to carry those particular
waste materials and all the necessary
documentation must be completed. The waste
carrier is responsible for ensuring that the waste is
taken to the correct disposal sites.Dispose of waste in accordance with the following
guidelines:
lFuel, hydraulic fluid, anti-freeze and oil –
keep separate and dispose of to specialist
contractor.
lRefrigerant – collect using specialist
equipment and containers, and reuse.
lDetergents – safe to pour down the foul drain
if diluted.
lPaint, thinners – keep separate and dispose of
to specialist contractor.
lComponents – send back to supplier for
refurbishment, or disassemble and reuse any
suitable parts. Dispose of the remainder in
ordinary waste.
lSmall parts – reuse any suitable parts, dispose
of the remainder in ordinary waste.
lMetals – can be sold if kept separate from
general waste.
lTyres – keep separate and dispose of to
specialist contractor.
lPackaging – compact as much as possible and
dispose of in ordinary waste.
lAsbestos-containing – keep separate and
dispose of to specialist contractor.
lOily and fuel wastes (e.g. rags, used spill kit
material) – keep separate and dispose of to
specialist contractor.
lAir filters – keep separate and dispose of to
specialist contractor.
lRubber/plastics – dispose of in ordinary
waste.
lHoses – dispose of in ordinary waste.
lBatteries – keep separate and dispose of to
specialist contractor.
lAirbags (explosives) – keep separate and
dispose of to specialist contractor.
lElectrical components – send back to
supplier for refurbishment, or disassemble and
reuse any suitable parts. Dispose of the
remainder in ordinary waste.
lElectronic components – send back to
supplier for refurbishment, or disassemble and
reuse any suitable parts. Dispose of the
remainder in ordinary waste.
lCatalysts – can be sold if kept separate from
general waste.
lUsed spill-absorbing material – keep
separate and dispose of to specialist contractor.
lOffice waste – recycle paper and toner/ink
cartridges, dispose of the remainder in ordinary
waste.

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).

GENERAL INFORMATION
03-21
It should be noted that these precautions are not
restricted to operations performed when servicing
the SRS system, the same care should be exercised
when working on ancillary systems and components
located in the vicinity of SRS components; these
include but are not limited to:
lSteering system – steering wheel airbag,
rotary coupler.
lFront fascia – passenger front airbag (where
fitted); SRS DCU behind centre console, on
transmission tunnel under the HeVAC system.
lFront seats – seat belt pre-tensioners, integral
with seat belt buckle assembly.
lElectrical system – SRS harnesses, link leads
and connectors.
Making the SRS system safe
Before working on or in the vicinity of SRS
components, ensure the system is rendered safe by
performing the following procedures:
lRemove the ignition key from the ignition switch.
lDisconnect both battery leads, earth lead first.
lWait 10 minutes for the SRS DCU back-up
power circuit to discharge.
The SRS system uses energy reserve capacitors
that keep the system active in the event of electrical
supply failure under crash conditions. It is necessary
to allow the capacitor sufficient time to discharge (10
minutes) in order to avoid the risk of accidental
deployment.
WARNING: Always disconnect both battery leads
before beginning work on the SRS system.
Disconnect the negative battery lead first. Never
reverse connect the battery.Installation
In order to assure system integrity, it is essential that
the SRS system is regularly checked and maintained
so that it is ready for effective operation in the event
of a collision. Carefully inspect SRS components
before installation. Do not install a part that shows
signs of being dropped or improperly handled, such
as dents, cracks or deformation.
WARNING: The integrity of SRS system
components is critical for safety reasons. Ensure
the following precautions are always adhered to:
lNever install used SRS components from
another vehicle or attempt to repair an SRS
component.
lWhen repairing an SRS system only use
genuine new parts.
lNever apply electrical power to an SRS
component unless instructed to do so as
part of an approved test procedure.
lSpecial Torx bolts are necessary for
installing the airbag module — do not use
other bolts. Ensure bolts are tightened to the
correct torque.
lAlways use new fixings when replacing an
SRS component.
lEnsure the SRS Diagnostic Control Unit
(DCU) is always installed correctly. There
must not be any gap between the DCU and
the bracket to which it is mounted. An
incorrectly mounted DCU could cause the
system to malfunction.
CAUTION: Ensure SRS components are not
contaminated with oil, grease, detergent or
water.
Ensure that SRS component fixings are correctly
positioned and torqued during service and repair.
CAUTION: Torque wrenches should be regularly
checked for accuracy to ensure that all fixings
are tightened to the correct torque.
If you suspect an airbag assembly could be
defective, install a new unit and dispose of the old
unit. Manually deploy the old unit before disposal.

low operating currents, always adhere to the
following precautions:
WARNING: Do not use a multimeter or other
general purpose test equipment on SRS system
components or accidental deployment may
occur. Use only Testbook to diagnose system
faults.
WARNING: Do not use electrical test equipment
on the SRS harness while it is connected to any
of the SRS system components. It may cause
accidental deployment and personal injury.
Never apply electrical power to an SRS component
unless instructed to do so as part of an approved test
procedure.
The SRS Diagnostic Control Unit is a non-
serviceable component and no attempt should be
made to repair or modify the unit.Component handling
