Has the "check engine" light been on at all while the engine is running? If not, then there might not be a diagnostic code to read, anyway. If no "check engine" light then there might not be any faulty sensors or actuators (i.e. nothing for the ECU to report)... which probably means a dirty MAF sensor, or maybe just a clogged air filter. If I were you, I would try cleaning the MAF sensor first with Isopropyl Alcohol - commonly sold as electrical contact cleaner. Give it a good soaking a few times, but don't touch the delicate electronic bits with anything. If that doesn't solve it, try a new air cleaner. If that doesn't solve it, try resetting the ECU.
As suggested before, check out the Error code PDF Error Code PDF Post. Even without knowing an error code, the listed symptoms might give you a clue as to a faulty sensor.
Are there any other symptoms? Is the car hard to start after stalling?

Ok... so I've done some more investigations. After perusing the ECU wiring diagram (http://trancemannz.orcon.net.nz/04%20SXE10...ranslation).pdf), I managed to figure out where I should be seeing at least 4 wires coming out of the ECU connectors for traction control purposes... and those wires aren't there on my car. I think that traction control is an ECU only function (no mechanical additions) but the extra wiring needs to be there maybe for sensor input (same sensors as for ABS?), or an extra processor? and probably the TRC off switch? can't read Japanese. I now think that those 2 extra sets of wires behind the panel that would normally house the TRC off button are probably for seat warmer switches. After a second look, the connectors on those wires are the same, just different colours.

I too have no traction control button, but if I pull out the tray that would normally have the traction control button mounted on it, I can see 2 lots of wires ending in plugs that are not connected to anything. Presumeably, one of these would normally be for traction control (I'm guessing the same wiring loom is installed in all models to reduce build cost). So the question is, is traction control a mechanical addition to the Altezza controlled by computer? Or is it purely a computer control function? i.e. Are all Altezzas traction control capable, and all that would be needed is to install the switch to activate the computer option?? Or is a different diff or gearbox or something else mechanical required to be installed?
