The door module is powered with 10 V from terminal 30 and with 10V by the SGM. The 10 V supply is buffered for the function of the ASE system. When replacing the door module, bear in mind that the capacitor needs a few minutes to discharge. The airbag might be deployed if you replace the door module with the capacitor still charged.
