Notes on Bluetooth Technology

A standardized radio connection is used for data transfer between the Information Electronics Control Module 1 -J794- and Cellular Telephone -R54- - Bluetooth Technology. The range of the radio connection is approximately 10 m.

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. Do not crush or kink the fiber-optic cables.

Repairing fiber-optic cables. Refer to GENERAL REPAIR INFORMATION .
