The airbag light in a 2003 Mini Cooper illuminates when the airbag computer determines that a problem exists within the airbag system. When the computer activates this light, it also disables the entire airbag system to prevent a malfunctioning component from potentially injuring one or more of the vehicle's occupants. This light must be turned off using an automotive scan tool connected to the Mini Cooper's diagnostic data port.
Place the Mini's gear selector in park or first gear (manual transmission). Turn the ignition to the "OFF" position to shut down the engine. Turn the ignition back to the "ON" position, but do not start the vehicle.
Power on the automotive scan tool. Plug its data connector into the Mini's diagnostic data port located under the dashboard on the driver's side.
Select "Airbag" from the scan tool's main menu. Select "codes," then select "clear all codes."
Disconnect the scan tool from the Mini's diagnostic data port. Start the engine and verify that the airbag light is no longer illuminated.
Automotive scan tools are small computer units that are designed to communicate with the vehicle's computer for diagnostic purposes. They are available from auto parts stores and automotive tool manufacturers.
