Notes on the MOST bus
In addition to the CAN-BUS, the optical data bus "MOST-BUS" is used. Connection to other bus systems is made via the diagnostic interface of the data bus "J533". A light guide is used as a "connecting cable". For protection, the light guides are laid in corrugated tubes. If possible, replace the entire optical cable. Ensure that the end surfaces of the plug connections are not contaminated. The plug connectors are disconnected: put on the protective cap for the cable plugs "VAS 6223/9".
When laying the light guides, observe the minimum bending radius of 25 mm. Do not squeeze or bend the light guides.
