Electrical system
The new MINI has the so-called Electrical System 2000. The Electrical System 2000 was introduced with the start of series production of the E65.
The Electrical System 2000 is made up of the following data buses:
- Body CAN K-CAN
- Media Oriented System Transport: MOST (from RAD2)
- Powertrain CAN PT-CAN
- Chassis CAN F-CAN (only with DSC)
- CAN interface for diagnosis: D-CAN (diagnosis-on CAN)
Between the diagnosis socket and the junction box electronics (JBE) there is now a CAN that acts as the diagnosis interface. The D-CAN interface has a higher data transfer rate (500 kBit/s). D-CAN is a twin-wire connection. D-CAN means: Diagnosis-on CAN

NOTE:
Modified MOST network from 08/2007.
The MOST port is located above the junction box and no longer above the footwell module. For this reason, the MOST network has a different appearance.
