There are several versions of the OBC, with different types of microprocessors. They are all mask programmed embedded microcontrollers, all of them obsolete by now. I can't remember exactly, but have seen four or five versions.

Have you ever tried dumping the ROM and/or pulling the eprom contents? I imagine the EPROM contains things like tank capacity, UOM, etc?

thanks for your comments.

I believe that it will be difficult to check the OBC,

but this component ( see the picture) can have some interaction with the OBC?

This is the fuel level sensor, and is of course involved in the fuel signal.
I have a full test bench for the OBC tacho.
