Okay, yep... got it. I did a preliminary tests on it. It works. How far it works... well I am still figuring that out. My kit is for Mercedes...

On my 95 diesel, it works on my AC and diesel engine electronic. The last option to diagnose is my airbag system and it didn't work. I am not sure if I have to do something more to get it to communicate with the SRS system.

On my folk's 01 gas engine, I hooked up the OBD2 harness and it worked in getting informaiton out of the Engine Module... but failed to communicate any other system that I want to get into... AC, BAS (brake assist system), ABS, and so other...

I need to find a manual on telling me how to do all this... which is not part of the software. I need to do more search on this matter.
