Components

The adaptive cruise control (ACC) has many control modules which are interlinked with the individual vehicle systems.

These control modules communicate with each other via the different bus versions. The data bus on board diagnostic interface (J533), which is connected to all the different bus versions, processes the data and sends it to the control module.

The control modules in the illustration are needed for the ACC to work. The control modules marked with a black dot are responsible for the core function. The other control modules are responsible for transmitting faults and for switching off the ACC. These control modules provide the visual and acoustic display for information and fault.

- Airbag Control Module (J234)

- Data Bus On Board Diagnostic Interface (J533)

- Front Information Display Control Head (J685)

- Front Information Display Control Head Control Module (J523)

- Multimedia Control Head (E380)

- Towing Recognition Control Module (J345) (optional)

- Comfort System Central Control Module (J393)

- Vehicle Electrical System Control Module (J519)

- Steering Column Electronic Systems Control Module (J527)/Steering Angle Sensor (G85)

Some control modules are optional, therefore only the control modules necessary for the ACC are installed.

Interlinking via the bus system. The wiring diagram shows the different bus versions and how the components are interlinked with each other.






Sensor Information to the Individual Control Modules

The ACC also uses various sensors which provide information to the control modules.
