SRS Harnesses and Connectors

CAUTION: Always observe the following
precautions with regards to SRS system
electrical wiring:

Never attempt to modify, splice or repair
SRS wiring.

Never 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:

Do not install a rotary coupler if it is
suspected to be defective.

Do not attempt to service, modify or repair a
rotary coupler.

Do not cut, splice or modify the wires
attached to the rotary coupler.

Always ensure the rotary coupler
connectors are mated correctly and securely
fastened.

Always ensure the battery is disconnected
before working on the rotary coupler.

Do not unlock and rotate the rotary coupler
when it is removed from the vehicle.

Do not turn the road wheels when the rotary
coupler is removed from the vehicle.

Always 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.

If 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.

Warning Labels
Warning symbols are displayed at various positions
in the vehicle (either in a suitable prominent position
such as driver and passenger side glass, or attached
to the component itself) to indicate SRS items which
must be treated with particular care. These include:

A - The need for caution when working in close
proximity to SRS components.

B - Refer to the publication where the procedures,
instructions and advice can be found (usually
Workshop Manual or Owner's Handbook) for
working on the SRS system.

C - Do not use rear facing child seats in the front
passenger seat if the vehicle is fitted with a
passenger airbag.

Driver and Passenger Side Windows

WARNING: It is imperative that before any work
is undertaken on the SRS system the appropriate
information is read thoroughly.

Caution labels are attached to SRS system
components and may also be applied to vehicle trim
close to SRS components and harnesses. The driver
and front passenger airbag modules have an 'SRS
AIRBAG' symbol moulded into the module's plastic
trim to identify the presence of airbags. Other SRS
warning labels include:

End of Fascia

Label located on end of fascia; warning not to use
rear facing child seats in the front passenger seat in
vehicles fitted with a front passenger airbag.

Rotary coupler

A   - Refer to the Workshop Manual for detailed
instructions.B   - Ensure wheels are in the straight
ahead position before removal and refitting.C   -
LAND ROVER Part Number/Bar code - The code
must be recorded and quoted for ordering purposes.

Front seat belt pre-tensioners

A warning label is fixed to the piston tube of the front
seat belt pre-tensioners:

Exercise caution.

Refer to the publication where the procedures,
instructions and advice can be found (usually
Workshop Manual or Owner's Handbook) for
working on SRS system components.

Do not attempt to repair or disassemble.

Bar codes

Driver's airbag module

Bar codes are fitted to SRS system components and
components which are critically related to SRS
operation. The code number(s) must be recorded if
the component is to be replaced. Components
featuring bar codes include the following:

Driver's front airbag module – label attached to
rear of module housing.

Passenger front airbag module – label attached
to rear of module housing.

Rotary coupler – label attached on face of rotary
coupler.

DCU – included on label on top of DCU.

SRS wiring – label attached around harness
wires.

VEHICLE RECOVERY
Observe the following procedures for vehicle towing
after a collision has taken place:

Towing – SRS components not deployed
Normal towing procedures are unlikely to cause an
SRS module to deploy. However, as a precaution,
switch the ignition off and then disconnect both
battery leads. Disconnect the negative '-' lead first.

Towing – SRS components deployed
Once the driver's airbag has been deployed, the
vehicle must have a front suspended tow. However,
as a precaution, switch the ignition off and then
disconnect both battery leads. Disconnect the
negative '-' lead first.

SRS component manual deployment

If a vehicle is to be scrapped and contains an
undeployed airbag module, the module must be
manually deployed. Always observe the following
precautions:

WARNING: Only personnel who have undergone
the appropriate training should undertake
deployment of airbag and seat belt pre-tensioner
modules.

WARNING: A deployed airbag or seatbelt pre-
tensioner is very hot, DO NOT return to a
deployed airbag module until at least 30 minutes
have elapsed since deployment.

WARNING: Only use approved deployment
equipment, and only deploy SRS components in
a well ventilated designated area. Ensure SRS
components are not damaged or ruptured before
deployment. Notify the relevant authorities.

WARNING: If a vehicle is to be scrapped,
undeployed airbag modules and pre-tensioner
units must be deployed in accordance with the
instructions in this manual.

WARNING: Contact with chemicals from
deployed and damaged SRS components could
present a health hazard, wear protective clothing
when handling. DO NOT eat, drink or smoke
when handling SRS components.

WARNING: Deployment of airbag modules and
seatbelt pre-tensioners can cause injury to
personnel in the close vicinity of the deploying
unit. In case of injury seek urgent medical advice.
Possible sources of injury include:

impact - due to inflating airbag or pre-
tensioner operation causing component
'kick'.

hearing - due to noise produced by
deploying airbags and seatbelt pre-
tensioner units.

burns - hot component parts and gases.

irritation to eyes and lungs - from deploying
gases or combustion residue.

WARNING: Ensure the SRS component to be
deployed is securely fastened to its mounting.

WARNING: Deployment procedures detailed in
this manual should be strictly adhered to.
Compliance with the following precautions
MUST be ensured:

Only use deployment equipment approved
for the intended purpose.

Before commencing deployment procedure,
ensure the deployment tool functions
properly by performing the self test
procedure detailed in the SRS Repairs
section of this manual.

Deployment of airbag/pre-tensioner
modules should be performed in a well
ventilated area which has been designated
for the purpose.

Ensure airbag/pre-tensioner modules are
not damaged or ruptured before attempting
to deploy.

Notify the relevant authorities of intention to
deploy airbag and pre-tensioner units.

When deploying airbag and seatbelt pre-
tensioner units, ensure that all personnel are
at least 15 metres away from the deployment
zone.

Ensure deployment tool is connected
correctly, in compliance with the
instructions detailed in this manual. In
particular, ensure deployment tool is NOT
connected to battery supply before
connecting to the airbag or seatbelt pre-
tensioner module connector.

When deploying seatbelt pre-tensioners in
the vehicle, ensure the pre-tensioner unit is
fully secured to its fixing point.

When removing deployed airbag and
seatbelt pre-tensioner modules, wear
protective clothing. Use gloves and seal
deployed units in a plastic bag.

Following deployment of any component of
the SRS system within the vehicle, all SRS
components must be replaced. DO NOT re-
use or salvage any parts of the SRS system.

Do not lean over airbag modules or seatbelt
pre-tensioner units when connecting
deployment equipment.

WARNING: During deployment parts of the
airbag module become hot enough to burn you.
Wait 30 minutes after deployment before
touching the airbag module.
