It is a Renault SID301 ECU from a Renault Megane 2. It was water damaged. Need to read it and copy to another ECU. This ECU is really cheap and don’t want to repair.
We can read this ECU with Xhorse Multi Prog via BDM.
Pinout is included in the multiprog documentation.
Select Renault->SID301
Check wiring diagram
Connect SID301 ECU with multiprog via MCU adapter follow the wiring diagram
Pinout is included in the multiprog documentation.
Solder carefully, don’t mix up the connection.
Double-check connection and make sure everything is connected to the device.
Then go to multi prog software.
Select Renault SID301.
Read chip ID
Read EXT eeprom
It was readed 100% now we are in the verify State and we have data overall. It took 12 seconds to read the eeprom memory.
Save eeprom. It reads eeprom very fast (28s).
Let’s read EXT flash data
Reading flash takes longer, but it worked.
It takes 8min 32s to read the flash data.
Then you can write original eeprom and flash to a donor ECU.
