Can i read/write  MC68HC912D60 to change VIN? Or any other way?
I didn't get any error while using NCS expert, and ISTA reported no error (green ECU), but i believe it isn't correctly coded.

Yes you can. A lot of tools support this MCU. It's secured so you need a special programmer (eg Xprog).
It's very likely that it's not coded correctly. Delete or change the VIN and recode it with NCS. Always worked for me.
Key data are also stored in BC1 so you better copy the complete dump if target is still readable to be on the safe side.

I'm unable to read both my BC1 modules. Tried with VVDI and xprog... Do you have correct pinout for this MCU?

Thanks
