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?

I am not sure what you are saying here? Why are you testing the OHM readings? Did you do a CAN scan to check for codes and if so what are they?

If you have not preformed the scan here is how it is done.

The codes will tell us the direction we need to go in instead of testing random wiring.
