SRS component replacement policy

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 / seat belt pre-tensioner modules should be performed in a well ventilated area which has been specially designated for the purpose. • Ensure the airbag / seat belt pre-tensioner modules are not damaged or ruptured before attempting to deploy • Notify the relevant authorities of the intention to deploy airbag and seat belt pre-tensioner units. • When deploying airbag and seat belt pre-tensioner units, ensure that all personnel are at least 15 metres way from the deployment zone. • Ensure the deployment tool is connected correctly, in compliance with the instructions detailed in this manual. In particular, ensure the deployment tool is not connected to the battery supply before connecting to the airbag or seat belt pre-tensioner module connector. • When deploying seat belt pre-tensioners in the vehicle, ensure the pre-tensioner unit is fully secured to its fixing point. • When removing deployed airbag and seat belt 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 seat belt pre-tensioner units when connecting deployment equipment.

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 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 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.

Front airbag deployment (driver and passenger)

If the front airbags are deployed, the following parts must be replaced:

• Driver airbag module
• Passenger airbag module (where fitted)
• Flyleads (where applicable) connecting front airbag modules to SRS harness
• Front seat buckle pre-tensioners
• Driver’s seat belt retractor
• Rotary coupler
• SRS DCU

In addition, the following should be inspected for damage and replaced as necessary.

• Front passenger’s seat belt retractor (webbing, tongue latching and anchorage point)
• Fascia moulding adjacent to passenger airbag module (where fitted)
• 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)
