DDT4all ECU read/write

[dtiberiu]

Hi everyone, First of all, allow me to introduce myself; I´m an electronic engineer pasionate of cars and I have a project consisting in replacing an Delphi ECU by a Siemens SID 301 ECU on an old Dacia Logan and do an immo off on the SID301 ECU. I tried to read the EEPROM of the SID 301 usind DDT4all but I cannot find this function. I was able to comunicate with the ECU on bench, I read the VIN and other information from ECU but I have not found the way to Read/Write ECU. SID ECU Hardware Microcontroller – FREESCALE MPC561 External FLASH memory – AM29BDD160GB (Memory size – 2 Megabytes) External EEPROM memory – 95320 (Memory size – 4 Kilobytes)

Looking forward for your help. Thank you.

There is no such functionality in DDT4ALL. This tool is not intended to do that kind of stuff.

I'm gonna give you some ideas how you can achive your goals:

• try ReadMemoryByAddress/WriteMemoryByAddress request to read/write EEPROM and FLASH (maybe Security Access is not required to at least dump these data)
• sniff CAN data when reading/writing FLASH using e.g KESSv2 to get an idea what requests are used to read/wirte FLASH
• disassemble SID301 BDM FLASH to get an idea what is the Security Access algorithm to be able to read/write FLASH
• disassemble Renault Immo Tool - it has all functionalities that you need
