How can I test my Idle Speed Valve?

Hi,
I've just hooked up my M880 to my Evo VIII (4G63) engine. Is it possible to test the ISV like we can with other AUX outputs? I tested to just click start bu nothing happened so I guess I'll have to do it some other way, but U just don't know how?
Is there any settings that I have to configure for the OEM Evo VIII ISV?
