The Subaru USB Diagnostic Tool for PC worked on my 2000 Subaru WRX (NZ new/Euro spec) and allowed me to look at any trouble codes and reset them as well as look certain engine parameters such as ignition timing etc. Also order and delivery from Stahlcar was excellent. I recommend them if you need diagnostic tools for working on cars.

Subaru Transmission is DOA, Diagnostic Tool to the Rescue!
I had to rebuild my 2002 Subaru Outback 4EAT, but it was not working. I had no way to find out why - Got this diagnostic tool - Only one I could find that would access transmission error codes. Found out which sensor was not working. Saved lots of time trying to find the problem.
