That processor accepts bootmode. Present in many ECD15 and ME7 ecus for example. Anyway it has only 32Kb internal memory, normaly relies on external flash. With bootmode you can read all memories, internal, external and serial eeprom.

Right, what´s the software/hardware I can use to read this 32kb internal memory?

KKL cable and nefmoto software, or minimon,...

For fun or for disassembly of the code purpose.

Have VIN and others informations programmed in the processor, I need change.

Don’t think you are gonna change anything on that processor’s irom, guess is factory programmed and otp. Also doubt VIN gonna be stored there, most likely all that data is in serial eeprom.
