hmmm, tricky. I'm not 100% on this, but obd2 didn't become mandatory until 2004 & 2007 from memory. One of those is diesel the other petrol engines. The other thing is which protocol they are using, as they still can use different protocols. Now since you connected to the car and have some readings, I'd think that points to OBD2 (as does the connector). But not definite. Now I just grabbed my Tech2 and scrolled through looking for the Barina, but it doesn't come up as an option until the 2006 model year. Kind of rules out finding someone with a Tech2 even (which was going to be my suggestion). Might have something to do with it being imported, I don't know. The thing is different cars will transmit different data too. For example, my VE shows a shed load of info with my ELM327, but the Landcruiser 200 series shows a lot less. Plus on the VE at least, it only shows "P" (powertrain) codes and not "B"ody, "C"hassis or network ("U") codes. So it won't show everything. But I shall assume you have a check engine light and that's why you know you have a code, which should be a "P" code as far as I know. Sorry about the rambling, insomnia is a bitch.
So some things to try that I can think of.
Find out what protocol the car is running. Also look for what it's called overseas if you can't find it. If you have a manual for it, it may be in there. Then check your ELM327 works with that protocol, or find one that does. You'll probably need to know this to find any scan tool that will work with it.
Try to find out if there's another way of finding out codes. eg. in my old VN, codes were read by shorting out 2 pins on the diagnostic connector which caused the CEL to flash a code. Again, a manual would help here.
Try another program other than Torque, there's a few freebies around you can try. But I use Torque myself as I found it to be the best and friendliest.
Worst option is see if you can figure out what's causing the code. Can you tell something is wrong or is behaving differently? Then post back on the chance you can give enough info for someone smart to give suggestions on what to do to check or confirm what the issue is.
Umm, that's all I can think of at the moment. Best of luck.
