SRS Harnesses and Connectors

CAUTION: Always observe the following
precautions with regards to SRS system
electrical wiring:
lNever attempt to modify, splice or repair
SRS wiring.
lNever install electronic equipment (such as
a mobile telephone, two-way radio or in-car
entertainment system) in such a way that it
could generate electrical interference in the
airbag harness. Seek specialist advice when
installing such equipment.
NOTE: SRS system wiring can be identified by a
special yellow outer sleeve protecting the wires
(black with yellow stripe protective coverings are
sometimes used).
WARNING: Always ensure SRS wiring is routed
correctly. Be careful to avoid trapping or
pinching the SRS wiring. Do not leave the
connectors hanging loose or allow SRS
components to hang from their harnesses. Look
for possible points of chafing.CAUTION: Ensure all SRS harness connectors
are mated correctly and securely fastened. Do
not leave the connectors hanging loose.
Rotary Coupler

CAUTION: Always follow the procedure for fitting
and checking the rotary coupler as instructed in
the SRS repairs section. Comply with all safety
and installation procedures to ensure the system
functions correctly. Observe the following
precautions:
lDo not install a rotary coupler if it is
suspected to be defective.
lDo not attempt to service, modify or repair a
rotary coupler.
lDo not cut, splice or modify the wires
attached to the rotary coupler.
lAlways ensure the rotary coupler
connectors are mated correctly and securely
fastened.
lAlways ensure the battery is disconnected
before working on the rotary coupler.
lDo not unlock and rotate the rotary coupler
when it is removed from the vehicle.
lDo not turn the road wheels when the rotary
coupler is removed from the vehicle.
lAlways ensure the rotary coupler is removed
and installed in its centred position and with
the front road wheels in the straight ahead
position - refer to the SRS repair section for
the correct removal and installation
procedure.
lIf a new rotary coupler is being installed,
ensure the locking tab holding the coupler's
rotational position is not broken; units with a
broken locking tab should not be used.

Air conditioning system precautions
General
The air conditioning system contains fluids and
components which could be potentially hazardous to
the service engineer or the environment if not
serviced and 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 the Air
Conditioning operating conditions and components
fitted to the vehicle.
Where necessary, additional specific precautions are
detailed in the relevant sections of this Manual which
should be referred to prior to commencing repair
operations.
The refrigerant used in the air conditioning system is
HFC-134a (Hydrofluorocarbon) R134a. Always
adhere to the following precautions:
WARNING: Servicing must only be carried out by
personnel familiar with both the vehicle system
and the charging and testing equipment. All
operations must be carried out in a well
ventilated area away from open flame and heat
sources.
WARNING: Do not allow a refrigerant container to
be heated by direct flame or to be placed near
any heating appliance. A refrigerant container
must not be heated above 50
°C.
Do not leave a container of refrigerant without its
cap fitted. Do not transport a container of
refrigerant that is unrestrained, especially in the
boot of a car.
WARNING: Do not smoke or weld in areas where
R134a is in use. Inhalation of concentrations of
vapour can cause dizziness, disorientation,
incoordination, narcosis, nausea or vomiting.
R134a is odourless and colourless. Do not
handle or discharge in an enclosed area, or any
area where the vapour and liquid can come in
contact with a naked flame or hot metal. R134a is
not flammable but can cause a highly toxic gas.
WARNING: Do not allow fluids other than R134a
or compressor lubricant to enter the air
conditioning system. Spontaneous combustion
may occur.WARNING: R134a is a hazardous liquid and when
handled incorrectly can cause serious injury.
Suitable protective clothing, consisting of face
protection, heat proof gloves, rubber boots and
rubber apron or waterproof overalls, must be
worn when carrying out operations on the air
conditioning system.
WARNING: Due to its low evaporating
temperature, R134a must be handled with care.
R134a splashed on any part of the body will
cause immediate freezing of that area. Also,
refrigerant cylinders and replenishment trolleys
when discharging will freeze skin to them if
contact is made.
WARNING: Under no circumstances should
refrigerant hoses be disconnected without first
discharging the system.
Do not disconnect any pipes in an air
conditioning refrigeration system unless trained
and instructed to do so. A refrigerant is used
which can cause blindness if allowed to contact
eyes.
WARNING: Refrigerant must always be recycled
before re-use to ensure that the purity of the
refrigerant is high enough for safe use in the air
conditioning system.
Recycling should always be carried out with
equipment which is design certified by
Underwriter Laboratory Inc. for compliance with
SAE J1991. Other equipment may not recycle
refrigerant to the required level of purity.
A R134a Refrigerant Recovery Recycling
Recharging Station must not be used with any
other type of refrigerant.
Refrigerant R134a from domestic and
commercial sources must not be used in motor
vehicle air conditioning systems.

GENERAL INFORMATION
03-30
Remedial actions
If an accident involving R134a should occur, conduct
the following remedial actions:
lIf liquid R134a enters the eye, do not rub it.
Gently run large quantities of eye wash over
affected eye to raise the temperature. If an eye
wash is not available, cool clean water may be
used to flush the eye. After rinsing, cover the
eye with a clean pad and seek immediate
medical attention.
lIf liquid R134a is splashed onto the skin, run
large quantities of water over the affected area
to raise the temperature. Implement the same
action if the skin comes in contact with
discharging cylinders. Wrap the contaminated
body parts in blankets (or similar materials) and
seek immediate medical attention.
lIf the debilitating effects of inhalation of R134a
vapour is suspected, seek fresh air. If the
affected person is unconscious, move them
away from the contaminated area to fresh air
and apply artificial respiration and/or oxygen
and seek immediate medical attention.
Service precautions
Observe the following precautions when handling
components used in the air conditioning system:
lAir conditioning units must not be lifted by their
hoses, pipes or capillary lines.
lHoses and lines must not be subjected to any
twist or stress - the efficiency of the system will
be impaired by kinks or restrictions. Ensure that
hoses are correctly positioned before tightening
couplings, and ensure that all clips and supports
are utilised.
lFlexible hoses should not be positioned close to
the exhaust manifold (less than 100mm) unless
protected by heat shielding.
lCompleted assemblies must be checked for
refrigeration lines touching metal panels. Any
direct contact of components and panels may
transmit noise and so must be eliminated.
lThe appropriate torque wrench must be used
when tightening refrigerant connections to the
stipulated value. An additional spanner must be
used to hold the union to prevent twisting of the
pipe when tightening connections.
lBefore connecting any hose or pipe, ensure that
refrigerant oil is applied to the seat of the new
'O' ring seals, BUT NOT to the threads of the
connection.
lAll protective plugs must remain in place to seal
the component until immediately prior to
connection.
lEnsure components are at room temperature
before uncapping, to prevent condensation of
moisture from the air that enters it.
lComponents must not remain uncapped for
longer than 15 minutes. In the event of a delay,
the caps must be fitted.
lWhen disconnecting, immediately cap all air
conditioning pipes to prevent ingress of dirt and
moisture into the system.
lThe modulator (receiver/drier) contains
desiccant which absorbs moisture. It must be
positively sealed at all times. A modulator that
has been left uncapped must not be used, fit a
new unit.
lThe modulator should be the last component
connected to the system to ensure optimum
dehydration and maximum moisture protection
of the system.
lWhenever the refrigerant system is opened, the
modulator must be renewed immediately before
evacuating and recharging the system.
lUse alcohol and a clean lint-free cloth to clean
dirty connections.
lEnsure that all new parts fitted are marked for
use with R134a.
