Reading Error Codes in INPA

[hunds02]

I've done a search and can't find what I'm looking for. Basically just want to use INPA to scan modules and for faults. Specifically, AC condenser (aux) fan isn't turning on (already replaced in 2013!) and want to use INPA to properly diagnose.

I've used NCS Expert to read and write modules for coding about a year ago, so I'm all set up. I can get to the screen and have both black dots light up confirming proper connection and between comp and car.

Then what? What specific module do I need to read? I'm surprised I haven't done this, yet I used the same software suite to code my car...

FYI.. I have the kit from the Romanian guy and I am on the same USB port (COM1, 1 ms latency etc...)
