dont unterstand? I added the output.
now I tried to understand the BUS analog ... means measurement with a multimeter.
results:
resistance HS CAN: 60Ohm
resistance MS CAN: 1,8MOhm
HS CAN H: 2.3-2.4V
HS CAN L: 2.5-2.6V
MS CAN H: 2,3V
MS CAN L: 2,9V
for me it looks like the MS CAN is the problem? but why cant connect to RCM?
this all doesn't make sense

No. Two 120's in parallel should read 60 ohms not 600. So both readings are incorrect. Did you disconnect the battery while taking the readings? The bus voltage can affect the resistance readings. While disconnected check the resistance of each line to ground. They should all be grater than 10k ohms.

@OldKarz 60 Ohm ... not 600 ... 600hm doenst make sense
but no, batt was not disconnected.
I checked the wiring diagram and disconected the AC control as gateway for the MS CAN. With this the dashboard and other devices aren't working, for me means the MS CAN could be OK.
