Yanhua Mini ACDP CAS data renew functions:

The EEPROM data of CAS1 – CAS4 can be renew. First load the EEPROM data from the other car, then modify the car frequency, VIN, ISN code and other information to generate new EEPROM data. So that it can solve the problem that the CAS EEPROM data lost or the CAS module damage and the EEPROM data can’t be read out and the CAS module needs to be changed.


Step 1:
Prepare the EEPRON data for the corresponding chip model and copy the data to the APP path: “:/ Atmatch/bmw/CAS4/CAS_Renew’, then select the corresponding EEPROM file for parameter calculation.

Step 2
Enter the VIN number, vehicle frequency, ISN code, etc that need to be modified, modify the loaded data and save it, the device will automatically clear the CAS mileage.


Step 3
Write the saved new EEPROM data to the CAS module, then load the CAS module


Step 4
After the module is loaded, if the vehicle cannot be started, or the “Direction lock” is displayed on the meter, please synchronize the ELV or DME according to the situation.


Step 5:
Use professional equipment to clear the trouble codes of the vehicle.


The original car key is invalid and you need to relearn the new key to start the car.
