K9 BCM X6/k73 telematics comm x2

I recently did an ohms test because the system was reading 120ohms. I disconnected the k73 x2 connector telematic module because it stop reading 120ohms, but still had an open circuit. I did the same test on the bcm module, I disconnected the x6 connector and the ohms read zero. My question is: is the bcm bad, or the path(wiring) to the telematic comm bad?
