How to use Yanhua ACDP to renew BMW CAS2?

Question: Hey on BMW cas 2 to write data can I solder directly to the board since I don’t have adapter?

My purpose is to renew cas.

Yanhua ACDP chief engineer replied:

You can read the CAS2 data by inserting ACDP MINI to the car’s OBD2 port.

If the CAS2 is dismantled, please buy one extra ACDP module 1 inside there is one BDM-ICP adapter, use it to read out the CAS2 data and to renew.
