- Driver's door P bus (driver's door switch block periphery bus)
- Engine LoCAN (engine Low CAN bus; link between DME and Valvetronic control unit)
- Telcommander CAN (Phone board CAN)
- M bus (air-conditioning motor bus)
- DWA K bus (alarm system body bus)
- BSD interface (bit-serial data interface)
