Introduction
The document “Functional Description 650” contains detailed descriptions of all electrical
systems and subsystems that are connected to the vehicles’ busses. There are also
references to other documents due to including them would go beyond the scope of this
document. These are for example Data Dictionaries and manuals.
The base for this document is vehicle state in October 2009 of 65x MY10,75. Thus some
MY11 subsystems are not included like Rear View Camera (RVC) and Side Blinde Zone Alert
(SBZA).
The systems will be split up into their network belonging:
• High Speed CAN
(including Chassis Expansion Bus)
• Mid Speed CAN / Infotainment
• Low Speed
• LIN
In addition, main functions will be explained separately, such as gateway functionality,
lighting, locking, sport mode, rear seat entertainment etc.
The information included in this document correspond to the actual state of the vehicle’s
systems by the time of going to press. Please do always check if changes have been made
to the systems! There is no guarantee for accuracy and completeness of the following
information!
