Check Engine light on & Cruse Control light flashing

Need info for a 2005 Forester XT turbo (USA). I drove into work this AM without a problem. After work, engine idled rough, had a steady check engine light, and flashing cruise light (flashes 1x per second), virtually no power at all. Checked oil, found it 1.5 qt low (this is the day after a long, long drive at freeway speeds). Added oil, now engine is smooth runs like it always has,(steady idle and normal power & accelleration), but the check engine remains on & cruise control light is still flashing once per second. Could this just be a residual indicator from the low oil? and now the system needs a reset to get the lights out? or ???? Can anyone advise how to pull the codes without a meter? How does one reset the check engine light? Thanks to all in advance.

You need to get the codes read. Autozone does it for free, they will give you a printout with what it means. Other auto stores may do it as well.

If there's no Auto Zone around, you can purchase a code reader for a lot less than a dealer will charge you to read it. Just plug it in, read the code, look in the book that comes with it or find the code on the Net and you'll have an idea of what's what. You can always reset the light with one of these inexpensive readers and see if it comes back on. It will if there is a problem. I carry one in the car and have used it more on other people's cars than my own. It's always been right.

The unit the dealer has can not only read codes but allow for all kinds of adjustments to the engine as well. They are very expensive.

UPDATE: I went out to the garage yesterday AM to drive over to AutoZone. The car started right up, rolled out of the garage and down the driveway. Put the car in drive, stepped on the gas, and nothing but idle. Parked in front of the house and called for a tow to the dealer. Problem is a bad relay in the "throttle by wire" circuitry. Dealer said he has only ever seen 2 go bad. Part not in stock, but due in tomorrow. Warranty covers.

its scary to know that all airplanes since A320 are fly by wire, too :)

I suspect that they may have more redundant systems that a car would.....

Final disposition: Check engine light resolved to code P2101, relay out of range. Tested, found relay out of specs. Replaced same. Subie is back to normal. :)
