Why Yanhua ACDP add “renew the EEPROM data of CAS1 – CAS4″?

Renew the EEPROM data of CAS1-CAS4. New EEPROM data can be generated by loading EEPROM data of other cars, modifying vehicle frequency, VIN, ISN code and other info, to solve the problem of replacement a CAS module because of missing EEPROM data of CAS module or failed

reading EEPROM data of CAS module.


Step 1:
Prepare a working EEPROM data of the corresponding EEPROM model and copy it to APP path as follows: “/ Atmatch/bmw/CAS4/CAS_Renew”, then select the corresponding EEPROM file to calculate the parameters.

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



Step 3
Write the saved new EEPROM data to the CAS module, then install the CAS module back to the BMW.


Step 4.

If the vehicle cannot be started or the direction lock is displayed on the instrument after the module is installed back to BMW, please synchronize ELV or DME.


Step 5:
Use professional equipment to decode the vehicle.


The original car keys have been disabled, it need to be re-learned to start the car.
