Repairs and Inspections Required After a Collision: Service and Repair
SRS Component Replacement Policy
The following information details the policy for replacement of SRS components; either as a result of a vehicle accident or as a result of vehicle age.
Impacts Which Do Not Deploy the Airbags or Pretensioners
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 Pretensioners
The replacement and inspection policy is dependent on the type and severity of of the crash condition. The following guidelines are the minimum that
should be exercised as a result of the deployment of specific SRS components.
If the front airbags or seat belt pre-tensioners are deployed, the following parts must be replaced:
^
SRS DCU.
^
Driver airbag module
^
Passenger airbag module
^
Front seat belt buckle pre-tensioners
^
Rotary coupler
^
Driver's seat belt retractor
^
Flyleads (where applicable) connecting airbags and seat belt pre-tensioners to SRS harness
In addition, the following should be inspected for damage and replaced as necessary:
^
Front passenger's seat belt retractor (webbing, tongue latching, 'D' loop, body anchorage point)
^
Rear seat belt buckles (webbing, buckle covers, body anchorage and tongue latching function)
^
Fascia moulding adjacent to passenger airbag module
^
Steering wheel (if damage is evident)
^
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)
^
Third row seats, seat belts and head restraints (where fitted). Check third row seat latching mechanism operates correctly.
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
are replaced after 10 years and seat belt pre-tensioners are replaced after 15 years in order to maintain occupant safety.
