Scrapping cars with airbags
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 airbags and belt tensioners 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 must be detonated using triggering device 84 71 104 (B) and cable assembly 86 11 469 (A).
1. Detonation 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. Remove the connector from the belt tensioner and plug in triggering device connector 86 11 469 to the belt tensioner.
9. Refit the 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 approximately 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, disconnect 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.
Scrapping Airbags
Airbags must be detonated using triggering device 84 71 104 (B) and cable assembly 86 11 477 (A). The triggering device consists of an approximately 15 meter long two-conductor cable 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. Park the car outdoors. The safety distance from the car is 10 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 2-pin connector. Connect the triggering device connector to cable assembly 86 11 477. Connect the cable assembly to the orange connector.
5. Passenger side airbag:
a. Remove the plastic covers from over the two screws securing the lower cover panel. Remove the screws. Withdraw the lower cover panel which is secured with clips. Use tool 82 92 997 and work from right to left. Do not use force.
b. Unplug the airbag's 2-pin connector. Connect the triggering device connector to cable assembly 86 11 477. Connect the cable assembly to the airbag's 2-pin connector.
6. Run the lead through the door opening and close the door. Check that all doors and windows are closed.
7. Position a battery 10 meters from the car. Connect the triggering device to the battery. Make sure that nobody is within the 10 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. Disconnect the triggering device leads from the battery immediately after the airbag has detonated. Wait 30 minutes before continuing work to allow the airbag's gas generator to cool down.
WARNING:
- If the airbag does not detonate at the first attempt, disconnect the triggering device from the battery and carefully examine the leads.
- Parts that make up the SRS must under no circumstances be removed from one car to be used in another.
