The data exchange of the systems in the MMI is done via the MOST Bus, the CAN Bus and the Ethernet.

Fault Finding is performed using the"Guided Fault Finding"  on the Vehicle Diagnostic Tester.

Notes on MOST Bus

The optical data Bus "MOST Bus" is used in addition to the CAN Bus.

A fiber-optic cable is used. Fiber optic cables are routed inside corrugated tubes for protection.

Replace the complete fiber-optic cable if possible.

The front surface of the connectors must not be contaminated.

If disconnecting the connectors: Attach the Fiber-Optic Repair Set - Connector Protective Caps :VAS 6223/9  .

When routing fiber-optic cables, make sure not to go below the minimum bending radius of 25 mm (0.98 in.). Do not crush or kink fiber optic cables.
