Hi. hope someone here can help me out.
I have a car with faulty CAS4 (terminal 15 error). I managed to get an used CAS4 (newer build date). I can read/write flash and eeprom from both CAS4.
However, the original car's CAS4 is older with 15LY mask and has only FLASH and EEPROM file. The one I wish to clone is newer one with 5NMH mask which has PFLASH, DFLASH and EEPROM.
Now, I can write back eeprom I read from original CAS to used CAS. However, is it possible for me to modify the used CAS's EEPROM to insert car's ISN and also VIN? If yes, may I know where should I edit and is there checksum to calculate for these 2 when editing?
Anyone can please advise. thanks!
