Hi,
I'm running MS2 on a V3.0 board using a 4 wires GM type IAC. The IAC was working fine with the stock ECU but I can't get it to move at all with MS2.
I have checked wiring continuity and switch the wires to IAC around but nothing is moving.
Is there a simple way to check if a signal is sent by MS2 to the IAC. Unfortunqtely I don't have access to an oscillo. Would a digital or analog voltmeter do the trick? what readings should I expect?
Thanks for your help
How can I test the MS2 IAC outputs?
