Scrapping Vehicles With Airbag and Belt Tensioners

To avoid injury when scrapping cars with airbag and belt tensioners, undetonated airbags and belt tensioners must be rendered unserviceable by electrical detonation as described below before the car is scrapped. These safety measures are essential as the pyrotechnical units can cause injury if handled incorrectly.


WARNING:
The airbag to be detonated must be correctly fitted in the car. Check that there are no loose objects in the vicinity of the airbag. Detonation of an airbag module that is loose or not fitted in place could cause serious injury.
There is a danger of accident if undetonated airbag modules or belt tensioners are exposed to high temperatures, for example when scrapping or if the parts loaded with explosive begin to burn or smoulder.

Scrapping Belt Tensioners
The belt tensioners are detonated using triggering device 84 71 104 (B) and cable assembly 86 11 469 (A).
1. Ignition in the off position. Remove the negative lead from the battery. Cover the negative terminal
2. Push the seat forward and fold down the backrest.
3. Remove the covers from the front and rear scuff plates.
4. Unscrew and remove the scuff plates.
5. Remove the screws holding the trim on the B-pillar.
6. Remove the cover, detach the seat belt guide from the B-pillar and remove the B-pillar trim.
7. Remove the plastic protector from over the belt tensioner.
8. Unplug the connector from the belt tensioner and connect triggering device connector 86 11 469 to the belt tensioner.
9. Refit the upper seat belt guide in its fastening (this is to protect the B pillar trim when detonating).




10. Check that the belt is running freely and can be pulled back approx. 180 mm without damaging anything.
11. Run the triggering device to the engine compartment. Close all doors and windows, checking that there is nobody in the car.
12. Connect the triggering device clamps to the battery terminals.
13. Stand in front of the car and press the triggering button.

WARNING:
- If the belt tensioner does not detonate at the first attempt, unplug the triggering device from the battery and carefully check the leads and the battery.
- Parts that make up the SRS must under no circumstances be removed from one car to be used in another car.





Scrapping Airbags
The airbag is detonated using triggering device part number 84 71 104 and cable assembly part number 86 11 477 for the steering wheel airbag (B) and cable assembly 86 11 469 for the passenger airbag (A). The triggering device consists of an approximately 15 meter long two-conductor lead with a push button and battery terminal clamps plus a connector for plugging into the car's wiring.

The battery to which the triggering device is connected must be in good condition.
1. Place the car outdoors. The safety distance from the car is ten meters. No persons or objects may be within the safety distance.
2. Make sure that nobody is in the car and that there are no loose objects in the front seat or on the facia.
3. Disconnect the negative lead from the battery.
4. Steering wheel airbag:
a. Remove the lower steering column cover.
b. Unplug the orange connector H2-52. Connect the triggering device connector to cable assembly 86 11 477 (B). Connect the cable assembly to the orange connector.
5. Passenger side airbag:
a. Remove the glove compartment.
b. Unplug the connector from the airbag. Connect the triggering device connector to cable assembly 86 11 469 (A). Connect the cable assembly to the airbag.




6. Run the lead through the door opening and close the door. Check that all doors and windows are closed.
7. Position a battery ten meters from the car. Connect the triggering device to the battery. Check that there are no persons within the ten meter safety distance from the car.
8. Detonate the airbag by pressing the triggering button. When the airbag detonates, the sound of an explosion will be heard and white smoke will be visible inside the car.
9. Unplug the triggering device leads from the battery immediately the airbag has detonated. Wait for 30 minutes before continuing work for the airbag gas generator to cool down.

WARNING:
- If the airbag does not detonate at the first attempt, unplug the triggering device from the battery and carefully check the leads.
- Parts that make up the SRS must under no circumstances be removed from one car to be used in another car.
