WARNINGS:
When handling an inflatable tubular structure (ITS) airbag module, hold by the gas generator housing, DO NOT hold by
the airbag. Do not wrap the thumb around the gas generator while holding. Do not drape airbag over shoulder or around neck.
For seat buckle type pre-tensioners, hold by the piston tube, with the open end of the piston tube pointing towards the ground
and the buckle facing away from your body. Do not cover the end of the piston tube. DO NOT hold buckle type pre-tensioners
by the bracket assembly or cable. Never point the piston tube towards your body or other people.
Airbag modules and seat belt pre-tensioners are classed as explosive devices. For overnight and longer term storage,
they must be stored in a secure steel cabinet which has been approved as suitable for the purpose and has been registered
with the local authority.
Store airbag modules or seat belt pre-tensioners in a designated storage area. If there is no designated storage area
available, store in the locked luggage compartment of the vehicle and inform the workshop supervisor.
CAUTION: Improper handling or storage can internally damage the airbag module making it inoperative. If you suspect
the airbag module has been damaged, install a new module and refer to the deployment/disposal procedures for disposal of
the damaged module.
SRS harness and connectors
Always observe the following precautions with regards to SRS system electrical wiring:
Never attempt to modify, splice or repair SRS wiring.
Never install electrical 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 wiring can be identified by a special yellow outer sleeve protecting the wires (black with yellow stripe
protective coverings are sometimes used). www.JagDocs.com

Deployment procedures and precautions as detailed in this manual should be strictly adhered to. Only personnel who have
undergone the appropriate training should undertake deployment of airbag and pre-tensioner modules. The following
precautions must be complied with:
Only use deployment equipment approved for the intended purpose.
Deployment of airbag / pre-tensioner modules must be performed in a well ventilated area which has been designated
for the purpose.
Make sure airbag / pre-tensioner modules are not damaged or ruptured before attempting to deploy.
Where local legislation exists, notify the relevant authorities of intention to deploy airbag and pretensioner units.
When deploying airbag pre-tensioner units, make sure that all personnel are at least 15 metres (45 feet) away from the
deployment zone.
Make sure deployment tool is connected correctly, in compliance with the instructions detailed in the SRS section of this
manual. In particular, make sure deployment tool is NOT connected to battery supply before connecting to airbag
module connector.
When deploying seat belt pre-tensioners, make sure pre-tensioner unit is secured correctly to the seat.
When removing deployed airbag modules and pre-tensioner units, 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 reuse or salvage any parts of the SRS system.
Do not lean over an airbag module when connecting deployment equipment.
If a vehicle is to be scrapped, undeployed airbag modules and pre-tensioner units must be manually deployed. In this case
airbags can be deployed in the vehicle. Before deployment, make sure the airbag module is secure within its correct mounting
position. Deployment of the driver's airbag in the vehicle may damage the steering wheel; if the vehicle is not being scrapped,
deploy the module outside of the vehicle.
SRS Component Replacement Policy
CAUTIONS:
The Restraints Control Module (RCM) will log a crash fault after every impact which is severe enough to cause airbag
deployment. It is possible to have three crashes/impacts logged after one event where, for example, a front, side and
rollover has occurred. After the third fault is logged, the SRS warning lamp will be illuminated and the RCM must be
installed. After any airbag deployment a new RCM must be installed.
The SRS side impact sensor must be replaced if there are any signs of physical damage or if the restraints control module
(RCM) is registering a fault.
The following information details the policy for replacement of SRS components as a result of a vehicle accident.
Impacts which do not deploy the airbags or pre-tensioners
Check for structural damage in the area of the impact paying particular attention to bumper armatures, longitudinals and
bracketry.
Impacts which deploy the airbags or pre-tensioners
The replacement and inspection policy is dependent on the type and severity of the crash condition. The following guidelines
are the minimum that should be exercised as a result of the deployment of specific SRS components.
Check for structural damage in the area of impact paying particular attention to bumper armatures, longitudinals and
bracketry.

Driver airbag module
Passenger airbag module
Fly leads (where applicable) connecting front airbag modules to SRS harness

Driver's seat belt retractor - if installed
Rotary coupler
Any front impact sensors that have been physically damaged or if a fault is being registered
Restraints control module (RCM) if the three crashes/impacts have been stored
Additionally, the following items must be inspected for damage and replaced as necessary:

General Information - Diagnostic Trouble Code (DTC) Index DTC:
Driver/Passenger Seat Module (DSM/PSM)
Description and Operation
Driver/Passenger Seat Module (DSM/PSM)
CAUTION: Diagnosis by substitution from a donor vehicle is NOT acceptable. Substitution of control modules does not
guarantee confirmation of a fault, and may also cause additional faults in the vehicle being tested and/or the donor vehicle.
NOTES:
If a control module or a component is suspect and the vehicle remains under manufacturer warranty, refer to the Warranty
Policy and Procedures manual, or determine if any prior approval programme is in operation, prior to the installation of a new
module/component.
Generic scan tools may not read the codes listed, or may read only 5-digit codes. Match the 5 digits from the scan tool to
the first 5 digits of the 7-digit code listed to identify the fault (the last 2 digits give extra information read by the
manufacturer-approved diagnostic system).
When performing voltage or resistance tests, always use a digital multimeter accurate to three decimal places, and with
an up-to-date calibration certificate. When testing resistance always take the resistance of the digital multimeter leads into
account.
Check and rectify basic faults before beginning diagnostic routines involving pinpoint tests.
Inspect connectors for signs of water ingress, and pins for damage and/or corrosion.
If DTCs are recorded and, after performing the pinpoint tests, a fault is not present, an intermittent concern may be the
cause. Always check for loose connections and corroded terminals.
Check DDW for open campaigns. Refer to the corresponding bulletins and SSMs which may be valid for the specific
customer complaint and carry out the recommendations as required.
The table below lists all Diagnostic Trouble Codes (DTCs) that could be logged in the Driver/Passenger Seat Module
(DSM/PSM). For additional diagnosis and testing information, refer to the relevant Diagnosis and Testing section in the
workshop manual.
For additional information, refer to: Seats (501-10 Seating, Diagnosis and Testing).
