The data exchange for the Bang & Olufsen sound system (9VS) and the TV Tuner -R78- (QV1) occurs through the MOST bus.

The connection to other vehicle systems is established through the CAN bus (Infotainment) and the Data Bus on Board Diagnostic Interface -J533-.

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 as a "connecting cable". 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. Do not crush or kink fiber optic cables.

Fiber-optic cable repair. Refer to FIBER-OPTIC CABLES, REPAIRING .
