Default How do you check engine codes?
I have read that there is a LED on the ECU itself that flashes, and not the check engine light, but I don't know how to trigger it.

I would assume that there is a check connector somewhere that needs a jumper, but I am not positive. This is for a 1991 Civic SI.

Thanks
