| The exchange of data in the MMI systems takes place via the MOST bus. |
| The connection to other systems in the vehicle takes place via the CAN bus (infotainment) and the data bus diagnostic interface -J533-. |
| In addition to the CAN bus, the fibre optic data bus „MOST bus“ is used. |
| A „fibre optic cable“ is used as the connecting cable. The fibre optic cables are fitted in corrugated tubes for protection. |
| Renew the complete fibre optic cable whenever possible. |
| The end faces of the connectors must not become dirty. |
|
|
|
| If connectors are unplugged: fit a protective cap for cable connector -VAS 6223/9-. |
| When installing the fibre optic cables, be sure to observe the minimum bending radius of 25 mm. Do not crush or kink the fibre optic cable. |
