Why you need to reset or replace airbag tool?
BWM airbag sensor after car crash and airbag deployment can by locked (Control unit faulty) and
must be replaced. Even after small accident Airbag sensor will write in internal memory special
error message "crash data stored" or “computer fault” and after you need to exchange very
expensive sensor to new one.

Using these pictures you can erase airbag “on the table” – you must connect GND, +12V,
and Diagnostic line between airbag sensor and BMW Airbag Eraser, connect power supply to GND and +12V and use Eraser like in the car. After erasing don’t connect power supply again – BMW airbag sensor is very sensitive and can write “controller malfunction” error after connection on the table without car.
