Networking/ Data Commmunications

Networking/Data Communication

- CAN (Controller Area Network)
- MOST (Media Oriented System Transport)

Electronic networking of the Cayenne enables data exchange among various control devices throughout the vehicle.

Compared to that of the sports cars, the data bus system is more extensive and consists of the following subsystems:

- CAN-drive bus, 500 kBit/s (in the event of a data line failure, e.g., short circuit or interruption, data transmission is impossible or limited).
- CAN-Infotainment 100 kBit/s (in the event of a data line failure, e.g., short circuit or interruption, data transmission is possible only via a single line - single wire operation).
- CAN-Convenience, 100 kBit/s (in the event of a data line failure, e.g., short circuit or interruption, data transmission is possible only via a single line - single wire operation).
- MOST optical data bus, 21.2 MBit/s (if one user cannot relay the data, no further communication is possible, due to the ring structure of the network).

To enable communication among the individual bus systems a Gateway Control Module, implemented as software, is located in the instrument cluster. Diagnosis is performed using the K-lead.
