I01￿General￿Vehicle￿Electronics
1.￿Vehicle￿Electrical￿System
Different￿data￿rates￿are￿used￿for￿the￿local￿interconnect￿network￿bus￿according￿to￿the￿information
required.￿The￿data￿transfer￿rates￿of￿the￿local￿interconnect￿network￿bus￿in￿the￿I01￿range￿from￿9.6￿kBit/s
to￿20.0￿kBit/s.
Examples:
• 9.6￿kBit/s￿exterior￿mirror,￿switch￿block￿at￿driver's￿door
• 19.2￿kBit/s￿FLEL,￿FLER
• 20.0￿kBit/s￿remote￿control￿receiver.
The￿Body￿Domain￿Controller￿is￿designed￿for￿the￿different￿data￿rates￿at￿the￿corresponding￿inputs.
1.3.2.￿Local￿CAN
In￿the￿I01￿the￿following￿Local￿Controller￿Area￿Networks￿are￿available￿with￿the￿corresponding
equipment:
• Local￿Controller￿Area￿Network￿from￿the￿optional￿equipment￿system￿to￿camera-based￿driver
support￿systems￿(KAFAS)
• Local￿Controller￿Area￿Network￿from￿the￿charging￿interface￿module￿LIM￿to￿the￿charging￿socket
at￿the￿vehicle.
The￿Local￿Controller￿Area￿Networks￿have￿a￿data￿transfer￿rate￿of￿500 kBit/s.
1.3.3.￿USB
Depending￿on￿the￿equipment￿the￿following￿USB￿connections￿are￿possible:
• from￿the￿headunit￿to￿the￿Telematic￿Communication￿Box￿(TCB)
• from￿the￿headunit￿to￿the￿telephone￿base￿plate
• from￿the￿headunit￿to￿the￿USB￿plug.
In￿vehicles￿with￿a￿Car￿Sharing￿Module￿the￿CSM￿is￿supplied￿with￿power￿via￿the￿telephone￿base￿plate.
1.4.￿Diagnosis￿access￿OBD2
The￿vehicle￿diagnosis￿via￿D-CAN￿is￿done￿using￿the￿OBD2￿interface.￿The￿Ethernet￿access￿for￿the
vehicle￿programming￿is￿also￿located￿in￿the￿OBD2￿interface.
