Door Modules

Door Modules





The door module contains separate modules for the door module electronics and the Advanced Safety Electronics.
The door module is the interface between:
^ Switch block, drivers door
^ Switch, passenger side
^ Door contact
^ Incremental sensor in power-window motor
^ byteflight
^ Power-window motor
The drivers door switch block is linked to the drivers door module by means of an LIN bus. Control of mirror adjustment, heating and front area light is also integrated in the door modules.
The ASK system is integrated in the Door Modules. The door modules also incorporate the activation system for side air bag deployment.

Note: When removing the door module, only unscrew the two outer screws(1). The inner screws(2) are exclusively for holding the door module housing together. Loosening the inner screws will cause operation of the door module to fail.

The door module is powered with 10 V from terminal 30. and with 10 V by the SGM. The 10 V supply is buffered for the function of the ASK 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.
