Anyone know what the self shut-off control does. Doing pin out values on my 96 ej18 Impreza for a no start, no spark, no fuel, no injector clicks. Seen a pin that said self shut off control and was wonder what all it kills and what triggers it. I have crank and cam signal at ecu but no rpm gauge movement and at the ignitor I have .6v give or take .1v. the ignitor won't ground the coil (new ignitor) I've checked all powers and grounds. At ecu and all check out. Starting to think I have a bad ECU. Thanks for any input. 

I dunno, could it be a 'roll-over' kill switch of some kind?

Idk I'm gonna check it's value tomorrow and see if it is triggered but I can't find anything on it online. Kinda figure its something like the Ford fuel shut off.
