Jarekmucha Posted October 28 Report Share Posted October 28 Hello, I have a problem with the MS CAN bus, namely it does not detect forscan SODL, DDM, HSWM and RGTM, SODR is detected. The voltage at the cube between pin 5 and 8 is 12V, on MS CAN 6 and 7 none, and on the working SODR about 1.7V Where do these trunk lines meet? 1 1 Quote Link to comment Share on other sites More sharing options...
Wubster100 Posted October 28 Report Share Posted October 28 Are you using a supported FORScan adapter? 1 Quote Link to comment Share on other sites More sharing options...
Jarekmucha Posted October 28 Author Report Share Posted October 28 Yes. Vgate. forscan sees the MS bus. but only the side of the ms bus where the voltage is 1.7V Quote Link to comment Share on other sites More sharing options...
dabangsta Posted October 29 Report Share Posted October 29 Hopefully someone can post the wiring diagram for those missing modules and you can see the MS-Can bus and where it might not be terminated or open. Seems like they are all on the left side of the vehicle or the wiring is routed on that side. I had to remove the existing profile for my vehicle and rescan it to get all the modules to show up. I used a different OBD-II adapter with a switch across bluetooth and it didn't get them all. Quote Link to comment Share on other sites More sharing options...
Jarekmucha Posted October 29 Author Report Share Posted October 29 I have Forscan and an OBD adapter VLinker F5, IT READS THE MS AND HS BUS. The problem is the lack of voltage on the MS bus section. I have information that the beginning of the bus is in the gateway module Quote Link to comment Share on other sites More sharing options...
Jarekmucha Posted October 29 Author Report Share Posted October 29 can someone send the diagram of the connector to the gateway module? Quote Link to comment Share on other sites More sharing options...

dabangsta Posted October 29 Report Share Posted October 29 Are you tracking down several failures or issues? Was the car in an accident or flooded or something else? I wonder where connector C900 is located and what the pin assignments are. All the items you list are on page 8 of the MCN document. On page 7 you can see the pins and connector (c900) that go to all those modules from the shared bus from the Gateway module. I don't have a heated steering wheel so that is why the HSWM is not found for me. Before I removed the saved config I only got about 2/3s of the modules. 1 1 Quote Link to comment Share on other sites More sharing options...

Jarekmucha Posted October 29 Author Report Share Posted October 29 Thank you for your HELP. I managed to solve the problem thanks to your tips and diagrams. The problem was very trivial... The c900 connector turned out to be the culprit. More precisely, I had the headliner removed which interrupted the MS-CAN bus THANK YOU ! 2 1 Quote Link to comment Share on other sites More sharing options...
dabangsta Posted October 29 Report Share Posted October 29 Glad you were able to solve it, and came back with the solution. Sometimes the reason for needing the information is helpful, knowing all those modules are off a branch of the MS CAN and all routed to the left side. 1 Quote Link to comment Share on other sites More sharing options...
