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 the connectors are disconnected: connect the Fiber-Optic Repair Set - Connector Protective Caps:VAS6223/9 from the Fiber-Optic Repair Set:VAS6223A .
When routing fiber-optic cables, make sure not to go below the minimum bending radius of 25 mm. Do not crush or kink the fiber-optic cables.
Fiber-optic cable repair. Refer to FIBER-OPTIC CABLES, REPAIRING .
