Problem:
I am having some problems with my Yanhua mini acdp 1st generation, I wanted to program a BMW FEM module and I always get this OBD communication error, we have tried to do bench and obd and always with the same error, have voltage 14v. on the other hand other tools are able to add a key.
Solution:
If had a obd communication error with ACDP, check if this component is damaged.
If yes, contact obdii365.com or your dealer to send you new component and replace it.
Feedback:
SOLVED!!!! This component is in bad condition!!! Now it works after replacement.
