OVERVIEW
A number of different types of communication network are incorporated into the vehicle wiring harnesses for the transmission of commands and information between control modules. The configuration installed on a particular vehicle depends on the model and equipment level.
The communication networks available on the vehicle are shown in the table below.
Note. For ease of reference, all networks are listed in alphabetical order.
| Network | Baud Rate | Protocol |
|---|---|---|
| Ai Net | 1200 kbits/s | Alpine proprietary system |
| Medium speed controller area network (CAN) bus | 125 kbits/s | ISO 11898 |
| High speed controller area network (CAN) bus | 500 kbits/s | ISO 11898 |
| DS2 Diagnostic bus | 9.6 kbits/s | Land Rover corporate for diagnostics + ISO keyword 2000* |
| Gigabit Video Interface (GVIF) | 1.95 Gbits/s | Sony proprietary system |
| I bus | 9.6 kbits/s | Land Rover corporate for body systems |
| K bus | 9.6 kbits/s | Land Rover corporate for body systems |
| Local Interconnect Network (LIN) bus | 9.6 kbits/s | ISO 9141 |
| M bus | 9.6 kbits/s | Land Rover corporate for body systems |
| Media Orientated System Transport (MOST) ring | 24 mbits/s | MOST co-operation |
