Marelli Dashboard Fiat Scudo 2013

[paskuale]

Hello mates,

I have a problem with Magneti Marelli Dashboard of Fiat Scudo Multijet 130cv year 2013 with Atmel Eeprom 25020AN.

I have to edit mileage from original 27819km to 5200km.

JCI BSI sucessfully reset to 0km with AVDI.
25020AN read ok with ABProg.


I edit the dump file to have 5200km like in attach.

But I have a problem when erase/write the eeprom: some parts of dump don't change !
Problem is from address 0x8 to 0xF.

I have to change the eeprom ?
My file is ok or I made a mistake ?

Thank you guys
Best Regards

Ori and mod dumps its ok.........but dump "reading mod eeprom scudo after write.bin" it is not good(there are too many differences).... remove dash and write dump with programmer

I removed eeprom from dash and I worked on eeprom with abprog programmer.
But I can't be able to write successfully mod dump: after complete erasing and writing of eeprom, the content is "reading mod eeprom scudo after write" dump.

I can't be able to erasing/writing mileage address from 0x8 to 0xF.

eeprom of this dashboard is protected against mileage roll-back ?
I need to change the eeprom ?

Best Regards

Do you try with another programmer?
Your programmer have external 12v+ supply conection?
If has you have to conected.

No, I didn't try with another programmer yet.
ABprog doesn't have +12v connection, only powered by usb.
