00FFF2 MOSTSYS: MOST ring break -1 unknown

I've been researching this for many months now and it seems like it's giving me gray hair. K-CAN Line Fault is still on.

I have used every module of the rear container and the modules of the seats as well. But K-CAN Line Fault does not lose anything.

 

Somewhere it is said that the SGM module could also solve this problem. Does it hold true?

However, the ISTA module in the tree has the SGM module in green.

 

What would you do next here?

Should we ask a Finnish person to look at something with an oscilloscope

I do know that there is a problem on the MOST bus side.
The problem is on whether the TEL/MULF is in place or not.

The currently installed loop.
