I bought my 2011 patriot in Nov of last year we'll i just jumped a friend for the first time not realizing that the battery had a cover over it well I thought the ECU was a battery connection so i pulled the little red handle and it killed the jeep. Got it going again but the check engine light is now on I had a coworker of mine scan it for me and it came up with no codes. I don't know much except for the basics (brakes, radiator, etc) so I'm at a loss any help would be greatly appreciated.
Thanks
