PRECAUTIONS
SRS SYSTEM COMPONENT REPLACEMENT
POLICY
Impacts which do not deploy the airbags or seat
belt pre-tensioners
Check for structural damage in the area of the impact,
paying particular attention to bumper armatures,
longitudinals, crash cans and bracketry.
Impacts which deploy the airbags or seat belt
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 specific SRS components.
Front airbag deployment (driver and passenger)
If the front airbags are deployed, the following parts
must be replaced:
•
Front impact sensors (NAS - distributed system
only),
•
Rotary coupler,
•
Driver airbag module,
•
Passenger airbag module,
•
Front seat belt pre-tensioners,
•
SRS diagnostic control unit (DCU),
•
Flyleads (where applicable) connecting front
airbags to SRS harness.
In addition, the following should be inspected for
damage and replaced as necessary:
•
Rear seat belt buckles (webbing, buckle covers,
body anchorage and tongue latching function)
•
Fascia moulding adjacent to passenger airbag
module.
•
Complete steering wheel assembly including
associated switches.
•
Front seat frames and head restraints (if there is
evidence of damage to the seat frame or cushion
pan).
•
Steering column (if adjustment is lost or there
are signs of collapse).
Side (Thorax) airbags
If the side (thorax) airbags are deployed, the following
parts must be replaced, on the side of the vehicle on
which deployment occurred:
•
Seat (thorax) airbag module
•
Seat squab foam
•
Seat squab cover
•
Front seat belt pre-tensioners
•
SRS diagnostic control unit (DCU)
In addition, the following should be inspected for
damage and replaced as necessary:
•
Front seat belt buckle and anchorage.
•
Rear seat belt buckles (webbing, buckle covers,
tongue latching and body anchorage)
•
Front seat frame (if there is evidence of external
or airbag deployment damage to seat frame)
•
’BC’ post internal finishers and fixings
•
Door casing
Periodic replacement of SRS components
The performance of the propellants within airbags and
pre-tensioners will deteriorate over a period of time.
As a result, it is essential that the airbags and
pre-tensioners are periodically replaced to maintain
occupant safety. Comply with the following periodic
replacement instructions:
•
Driver and Passenger airbag module - every 10
years
•
Side (thorax) airbag modules - every 15 years
•
Front seat belt pre-tensioners - every 15 years
