  1. Get a Mitsubishi airbag scanner
  2. Plug the scanner into the OBD2 port under the dashboard, driver's side. 
  3. Turn on the ignition and allow the scanner to power on. 
  4. Select your Mitsubishi model. 
  5. Select SRS / Airbag Control unit from the main menu. 
  6. Select Read Fault Codes. Write down all the codes and also make sure they are NOT PRESENT. 
  7. Go back to the main menu and select Clear Fault Codes. 

You should only clear Mitsubishi airbag fault codes if they are in Stored or Past status. Do not clear Current, Active or Present codes without fixing the problem. Typically even if you try to erase present Mitsubishi airbag codes, they return as soon as you restart the car.
