I finally got the adapter to start reading the can bus signals so i can make my own cruise control system and the wires on the adapter had pre striped wire ends and I was not careful enough and shorted out the power wire on the OBD2 port which went dead and the car turned off and would not start!!!! It turns over but the spark ignition coil would not turn on. After I tested all fusses and found no dead ones I tried applying 12V to the dead wire where there used to be 12V on the OBD2 port and the car would start again.

so I am probably powering the ECM through the OBD2 port with a wire directly connected to my car battery!!

I need the can bus wiring diagram and the ecm wiring diagram

Hello. New here. Just bought a 2011 Aveo from an auction with no key. Got a key cut and now have crank, no start. I do have fuel pressure and do not have commas when I plug in my scanner. I’m looking for the wiring diagram for the ignition coil so I can test to see if it’s faulty. I’m starting here because it was disconnected and unbolted when towed, so...
I’ll address the no comment with scanner once I get it running, if possible.
Anyway, ignition coil schematic would be greatly appreciated. Thank you!
