Scrapping cars with airbags and seat-belt tensioners
|
To avoid injury when scrapping cars equipped with airbags and seat-belt tensioners, all undetonated airbags and seat-belt tensioners must be rendered unserviceable by electric detonation before the car is scrapped, as described below.
These safety measures are essential, as the pyrotechnical units can cause serious injury and material damage if handled unprofessionally.
|
Note
|
|
The detonating device used consists of a two-conductor cable about 10 metres long with a pushbutton, battery clips and connectors for plugging into wiring harnesses. The wiring harnesses should be changed according to the SRS component that is to be scrapped.
|
|
The battery to which the detonating device is to be connected must be in good condition.
|
Warning
|
|
The airbag and/or seat-belt tensioner to be detonated must be correctly fitted in the car. Check that no loose objects are present in the vicinity of the airbag.
|
|
Detonation of a loose or unmounted airbag module could injure persons in the vicinity.
|
|
An accident could happen if an undetonated airbag or seat-belt tensioner is exposed to high temperature, such as in connection with scrapping, or if parts with an explosive charge start to burn or smoulder.
|
|
|
|
|
|
|
Warning
|
|
Splicing of SRS leads is strictly prohibited.
|
|
Splicing can cause malfunctions which could render the system unserviceable and in the worst case lead to injury.

Scrapping belt tensioners
|
Belt tensioners should be triggered using detonating device 84 71 104 (B) and wiring harness 86 11 469 (A).
|
Warning
|
|
Belt tensioners that are to be detonated must be correctly fitted in the car.
|
|
Detonation of a loose or unmounted seat-belt tensioner could injure persons in the vicinity. An accident could happen if an undetonated seat-belt tensioner is exposed to high temperature, such as in connection with scrapping, or if parts with an explosive charge start to burn or smoulder.
