Yanhua Mini ACDP + module 3 + adapters.
Procedure:
Steps for matching CAS4+ key ( all keys lost):
1. Read DME ISN code Different models can be read in different ways, refer to the APP help documentation for details. Take the video of reading N20 engine ISN code by drilling hole as an example
2. Read CAS4+ module EEPROM data
3. Program key.
Note: CAS4 + requires a working key, CAS4 not. But the OBD operation options are the same, the ACDP will automatically distinguish between CAS4 and CAS4 +.
Good luck!
