Nevermind i got it to work!  But now i get a lot of these statments- CB684: can't rename byte as 'Primary_Open_Loop_Fueling_Failsafe' because this byte can't have a name (it is a tail byte). Can i do anything to fix this?

Make sure that the Ssmget routines on the other side of the reference table are properly decoded - other you will have o manually force them to become code (highlight the section, press C, F then yes).

I'm very new to IDA and disassembly! I was hoping I could disassemble my rom to point where I could begin to explore it in the hope that I could understand it better. I’m really struggling because I’m not sure what the code/data is meant to look like and if what I have done is correct or not.
Do you have any suggestions? How do I tell if code is code and if data is data or not?
Also could you please describe how to find these “Ssmget routines on the other side of the reference table” is it the routines following ssm base?
I'm not even 100% sure if I've found the correct ssm base adress!

I suggest reading the how to get started with IDA thread again, the only way is through doing - you'll get the hang of it, takes time.
Have a look at some of my 'new definitions' threads - there are examples of data and code locations there.

Just undefine (u) the address area that those messages pertain to. It's trying to define a byte value that has already been defined as something else (word or dword).

Thank you! I actually found this out by accident just today, I had to undefine alot of the data area for the idc script to work!
Now all i need to do is learn the instruction set so i can work on the loggic!

Then annoying as hell afterwards  You still need the SH2E software manual so you can refer back to which branch/jump is slotted or not, which add, mov, etc. use which type of offset. It's best to print the summary pages out to have a handy reference in your face all the time.

Thanks for the tips! I need all the help i can get at the moment!
So should I have disassembled my rom with SH2E? My ecu is a SH7058.

Does this look right? I just want to make sure the formatting is correct for the SSM address before I keep rolling: Code: C:\Windows\system32>cd C:\Program Files\RomRaider
C:\Program Files\RomRaider>XmlToIdc.exe tables A2ZJB11J > Tables.idc
C:\Program Files\RomRaider>XmlToIdc.exe extparam 3D12594106 > ExtendedParams.idc
C:\Program Files\RomRaider>XmlToIdc.exe stdparam A2ZJB11J 0004858 > StandardPara
ms.idc

What exactly is an SSM read vector, and how do I find it? I'm also very new to this
I'm working with 16 bit roms

Same error for me This is answered above - go to those locations and undefine them.
