Interior CAN Check
In DAS, if you go to guided tests on the CAN B connected modules, you can perform tests where the multiplexer is directly connected to the CAN B bus at X30/15. The requires the 8 pin cable and a couple of additional cables to connect. One cable is 220589009930 which looks like it has red and black banana sockets to accept the pins red and black pins from the DAS 8 pin cable (6511240099) and large and small CAN plugs to fit the various models. The other cable referenced is 220589009900, which sounds like some sort of power cable, perhaps to power the multiplexer since it will not be getting power from the diagnostic port. I have not found any pictures or additional information on this cable.
One very useful feature on this procedure over the regular diagnosis is that you can monitor the wake-up signals on CAN B. This should help to find power drain issues since CAN wake-up or failure to sleep would cause high consumption. You can also monitor actual values being transmitted over the bus. These values are obtainable on other modules, but this would allow you to see if missing data is due to transmission or reception problems.
Has anyone obtained/made these cables and performed this test or found additional documentation?

I have this cable 6511240099 https://www.ebay.com/itm/224202240838 that came with my C4 DAS system. It connects to the multiplexer. Not sure where the banana clips go and how it connects to the X30/15.
The multiplexer accepts that cable on one end and on the other the multiplexer connects to the laptop (STAR system) via RS232 port.
Would you know how to connect to the X30/15?
