Yanhua ACDP Set Module 1

What Module 1 does

It is mainly used for BMW CAS (Car Access System) IMMO work, including:

• Key programming (add key / all keys lost)
• Works on CAS1 / CAS2 / CAS3 / CAS3+ / CAS4 / CAS4+
• Odometer (mileage) correction for CAS system
• Read / write EEPROM & flash data
• CAS data backup / restore / renewal
•  Works via OBD or ICP (bench/in-circuit mode) depending on CAS type
  

  Important limitations

  Module 1 alone is not enough for full BMW work:

  •  For all keys lost (some cases) → needs Module 3 (ISN module)
  •  For FEM/BDC BMW systems → needs Module 2
  •  For dashboard mileage (KOMBI) → needs Module 4
