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.
