SRS Component Deployment

SRS Component 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 pre-tensioner modules.


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


WARNING: Deployment procedures detailed in this service 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 this section.
- Deployment of airbag I pre-tensioner modules should be performed in a well ventilated area which has been designated for the purpose.
- Ensure airbag I 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 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 airbag module connector.
- When deploying seatbelt pre-tensioners in the vehicle, ensure pre-tensioner unit is secured correctly to 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 re-use or salvage any parts of the SRS system.
- Do not lean over airbag module when connecting deployment equipment.


WARNING: If a vehicle is to be scrapped, undeployed airbag modules and pre-tensioner units must be manually deployed in the vehicle; before deployment, ensure the airbag module is secure within its correct mounting position.


CAUTION: Deployment of the driver's front airbag in the vehicle may damage the steering wheel; if the vehicle is not being scrapped, deploy the module outside of the vehicle.


CAUTION: Deployment of the side airbags will rupture the seat covers; if the vehicle is not being scrapped, deploy the module outside of the vehicle.
