When all keys are lost, can I get the ISN code of BMW FEM/BDC from OBD by using Yanhua mini ACDP? Also, when all keys are lost, can you get CAD data from OBD?
Is it okay if the car is turned off?
Yes to all questions above. But you need ISN+ FEM/BDC authorization.
Yanhua ACDP is able to Read following ISN code via OBD when all keys lost :
MSD851 (supports E-series only currently) DME
Yanhua Mini ACDP program FEM/BDC all keys lost no issue
Here’s the wiring connection
Here’s the video demo
It will do when engine is turned off. But you need to run “FEM/BDC Activate” first. The function is a free bonus when you order FEM/BDC authorization.
FYI: Yanhua mini ACDP supports following ISN code reading as well, but need to remove DME.
