Door Modules
The Door Module is integrated into the ASE. It communicates with other vehicle systems via the byteflight.
The Door Modules contain the following functions:
- Mirror Adjustment, Heating, Memory, Folding and Lighting
- Central Locking (Front Doors Only)
- Front Power Windows (with indirect anti-trapping)
- Connection to Driver's Door Switch Block
- Connection to Passenger's Door Power Window Switch)
- Door Entry Lights and Switch Illumination
- Recording of Front Door Pressure Sensor Information
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, driver's door
- Door contact
- byteflight
- Switch, passenger side
- Incremental sensor in power-window motor
- Power-window motor
The driver's door switch block is linked to the driver's door module by means of an LINBus. Control of mirror adjustment, heating and front area light is also integrated in the door modules.
The ASE system is integrated in the Door Modules. The door modules also incorporate the activation system for side air bag deployment.
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.
