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.
