I am not an idiot and like I think I know what I'm doing, but this has me mind boggled, 03 chassis with 06 motor engine harness an ecu, fsm diagnostic procedures are the same for both years.

Output voltage for the ecu is supposed to be 4v and then when the on switch for cruise control is pushed it should drop to 0v to turn on the cruise control.

No matter which way I check it I'm getting .3v from the ecu and then .6mv when the main switch is pressed, is there anything that would cause this low voltage, ground appear to be good as everything else on its ground circuit is functioning

 

So apparently there no electrical gurus out there huh? I guess this would make me your go to guy for 350z wiring not being a d*ck but seems like no one knows any better than I do? Or is this forum just dead?
