Replying to: 2009buyer (Feb 17, 2009 12:11 pm) I got an Actron for $99. Make sure it can read and reset codes also.

Replying to: horspoor (Jan 03, 2008 2:01 pm) I usually go to my local O'Reilly's and use thier scan tool for free! Hope this helps. Most parts stores do this. Why buy one. Replies to this message: 2009buyer (Feb 20, 2009 8:00 pm) xwesx (Feb 23, 2009 11:48 am) ateixeira (Feb 24, 2009 1:25 pm)

Replying to: scoobydoo4 (Feb 20, 2009 6:54 pm) I have read the posts and appreciate the feedback. Unfortunately I am not sure what I would do with a scanner if I had it. If I bought one, used it according to the manual, then what? It gives me some codes, I read them, don't know what to do about any of it. Don't know what would happen if I re-set the codes. Does that make the check engine light go out? So it would pass smog?   I don't have an O'Reilly in my part of California. Anyone else know of somewhere they do this. Like a Kragan or Pep Boys?   Since this seems to be a common problem, what does Subaru say about this? Replies to this message: xwesx (Feb 23, 2009 11:48 am) ateixeira (Feb 24, 2009 1:25 pm)

Replying to: Pbalkan (Feb 16, 2009 11:20 am) OK.... I bought a scanner. And.... I have just made the trip from high-altitude to low and from cold to hot. I haven't got a CEL.... yet... but I usually get one within 24-48 hours after I make the trip.   Of course, now that I have the scanner.... the car might just fix itself to spite me.   I found the OBD2, 16 pin connector. Subaru "hides" it in plain sight. I was looking for some kind of hatch-cover but it's just THERE, next to the hood latch. I read somewhere that there are connectors that must be connected to put the car into test-mode. The connectors are supposed to be around the glove-box.   True? Where do I find those?

Replying to: Pbalkan (Feb 22, 2009 2:33 pm) Nah, just follow the instructions that came with the scanner.   I didn't need to find any connectors for any of the cars I've scanned. You just plug-and-play. Read the instructions to find out where to put the ignition switch and when.

Replying to: 2009buyer (Feb 20, 2009 8:00 pm) I cannot offer feedback on most of your questions here, but as for "don't know what to do about any of it," I recommend that you simply write down the codes. You can read them without clearing them, which then leaves the codes in there. Or, you can read and then clear, which does turn off the CEL. Assuming no other problems, it should pass inspection.   If you keep a log of the codes and dates/circumstances that may be involved with the code, you might be able to help a mechanic diagnose the problem. The codes themselves are symptoms and do not always point directly to the problem. If the light is on and you take it to a shop, they may very likely be unable to correctly diagnose and repair the problem They will, however, be far more likely to recommend work and throw parts at the problem.   The code reader is not a replacement for repair and maintenance - it is a tool to assist those efforts.

Replying to: xwesx (Feb 23, 2009 11:48 am) Indeed, get the code and Google them, or come here and ask if others have seen it.   It helped me trouble-shoot a bad ignition coil once.
#104 of 148 Thanks by andydg Apr 23, 2009 (8:05 am)
Followed the advice here and now own a memoscan U480, read the codes and erased them putting out the lights. VDC, CEL, flashing cruise light. Codes noted in case it repeats.   Thanks guys some great advice here.   Andy in the UK

Replying to: lostinmaryland (Jan 29, 2008 9:06 pm) i have a 1995 lagacy L station wagon, my check engine light stays on all the time. I had it scanned and was told it was the air flow senser which is connected to the air filter box. I replaced it and still have the same problem. Anyone got any suggestions??? I'm at a loss. Thanks.

Replying to: gordon_junkie (Apr 24, 2009 4:39 pm) I got rid of my 1996 in January because of the same problem and the propensity of garages to charge for things cars don't need. The dealership looked at mine under warranty way back when and could never find anything wrong with it. Several people on this forum have advocated to buy a scanner and then just clear the codes and the light goes out. But mine went back on after about 100 miles. So unless you have to have it smogged and have the light out for that, just ignore it and go your merry way. I think it is a flaw in the car since mine had that problem from about 45, 000 miles to 188,000 miles. Great car anyway.
