This is a discussion on Help! Check engine light flashing as soon as the key is on within the STi Technical Forum forums, part of the Tech & Modifying & General Repairs category; Originally Posted by mustangturbo50 hmm im not seeing a box thats why i was thinking it was just buried in ...
im just going of my mitchell software and it says behind right side of dash
lol yeah i guess if you look at it that way
It's probably in here:
2009 DGM WRX 5-door w/ STI short shifter. Stock...for now.
Well, this is just a guess....
But, it when you turn the key on to accessory (not all the way on) and the CEL blinks, and the relays and the fans keep cycling off and on, sounds like you have the test connectors under the steering wheel hooked up. Do you have an accessport, or did you recently buy it used? Or have you taken it somewhere for service or inspection recently? I forget the color of the connectors in an '02, but the other years are green. If you look under the steering wheel (all the way, from the gas pedals look up) and you see either a green wire connection or a white wire connetion, disconnect the 2 plugs from one another. That would theoretically do it....
EDIT: The more I read this over, I'm 99% sure this is your issue.

Two hours late, but yeah, unplug the test connectors. Your looking at old code history. Also your driving in limp home mode.

Glad to see we're in agreement. . I guess the real question is when / why were they connected in the first place. And, if they've been that way since he bought it, he's in for a whole new driving experience!
+1 on the whole new driving experience!
However I would suggest to you check with the place that read the codes for you, they might have connected them and forgot to unplug them. Which means you might still have some issues.

I know this thread is from four years ago, but I wanted to say thanks!
A couple months ago, I had an alarm issue, and someone stopped to help me when it wouldn't shut off one day. Unfortunately, the guy just started rummaging around, pulling fuses, disconnected the horn, etc. I told him I could handle it, and I tooled around a bit and figured how to actually fix the problem. But when I reconnected the horn and replaced the fuse he had pulled, I found that my check engine light started flashing rapidly and the fan started clicking on and off as soon as I put the key in. When I started it, the idle was irregular. I knew the CEL hadn't been coming on before, and I was afraid it had something to do with what this guy had done. I hooked it to the computer and checked the codes, and I knew the long string of errors that came back just didn't make sense, but no one could figure out what was going on. It stumped a few mechanics, and internet searches had been useless because they all just brought up actual CEL errors, and I knew this was something else. I was about to dump a bunch of money into electrical diagnostics, looking for a short or something. Then after another google search, I finally found this post! So obvious! I checked and found that the guy who stopped to help me must have found the test connectors and decided they needed to be connected. I pulled them apart, and the problems are gone! And my WRX runs better than it has in months!
I'm posting a response to keep this fresh in the search engine results. Hopefully someone else looking for a solution will find this post. This has been a huge pain in the ass, as it delayed my smog check and registration and was really getting annoying. Thanks to those who were awesome enough to post the solution!
