RomRaider

I can't find the DTC SupMask on this ROM. I don't have access to the Nissan service manual for this one which would tell me which fault codes are supported and I could usually work it out from that.

It's usually always nearby before or after the ECU ID (0x893C on this ROM) but I'm seeing what looks like axis data (data growing with a pattern) already very close to this and I disassembled it in Ghidra and still unsure.

Can anyone identify the DTC SupMask start address?

The DTC Descriptor table starts at 0xA510 and the option pointer list starts at 0xA990 if that helps.

p.108 Nissan Cube (Z11) JDM ???

DTC SupMask is usually located immediately after the second copy of the QH0/torque conversion map. 0xA212 ???

0xA516 reverse byte order

Thanks! I must admit, I didn't really look



Yep I think that's it. Thanks! That's good to know.



The start of the table is a little before the first fault code. 0xA510 is the byte referencing which SupMask byte applies for the first fault.
