We also had this ACC-message flashing in the driving computer of the Legacy 2004. The Subaru garage had no idea what it was. But recently we prepared the car for selling it and that solved the problem. What we did was removing the (unoffical) cellphone loader. We also removed this device that can send radio waves from an MP3 player to the car radio.
Are theory is that one of these devices had some electrical short circuit that would only appear when the car was in use. Therefore the car battery would not be emptied when the car was not un use. The last 2 weeks after removing these devices, we never got the message again. To those of you who get this ACC message: please try my theory and confirm it.

Our radio quit working and we had an ACC error code on the display. Nothing was listed in the book for this code and none of the dealers could give us an answer. We tried changing the fuse even though it wasn't blown. It seems to have worked. The ACC went away and the radio and display started working again.

#128 of 169 2005 Outback dome light madness by smoky1

The dome light doesn't light when the doors open. I pop off the cover, and then it works. It keeps working after I pop the cover back on a couple of times and then stops again. The bulb is ok. The electronics seem ok. But something is intermittent somewhere. If I wiggle or otherwise try to encourage the dome light, it still won't start working. I have to pop off the cover and then it will work a little while. Aaarrgh!! Anyone ever see this before?

It may be a bad connection, or it may be a broken bulb filament that reconnects with a jar (such as popping off the dome cover). As a cheap first option, replace the bulb if you have not yet done so and see if the problem persists.

Did you get this problem fixed? I have a 2009 Legacy that is doing the exact same thing. It is so frustrating. I just had the audio panel replaced but it is still doing it.
Thanks.

#131 of 169 Signal Lights think they are emergency flasher by bigdan4

Jun 20, 2011 (7:20 pm)

I have a 99 forester with 80,000 miles. Turning the any signal light on results in all 4 lights flashing and th 4 way flasher lighting up. In the connector at the right side of the dash, below glove box, the light green/black wire and the red/green wire seem to be shorted. I cannot find where they go so that I can replace them. I have all the Schematics but cannot find the wires anywhere.

#132 of 169 serious unresolved electrical problem by lostwooutback

Sep 28, 2011 (9:37 am)

Three days ago I was driving in the rain in the highway, suddenly the speedometer and rpm dial needles started going crazy, up and down, and the wipers were going slower than normal. The abs light and others in the dashboard came on. Although the car never lost power completely, we decided to tow it home (30 miles), to avoid further damage to the car, and left it at my trusted mechanic. The mechanic charged the battery and checked it and the alternator. All was fine. He says he cannot figure out what caused the battery to lose power and what could be wrong. The RPM & speedometer went crazy again yesterday. We had to leave the car in a parking garage. What could this be? Is my dear, dear car lost forever?

I forgot to add, the car in trouble is a 2001 Outback Legacy (I love my car!)

Not sure, but I recall a discussion about a single point ground, to solve issues like that. It was common enough that people came to use the acronym, SPG, by itself.
 
Google it and see what you can find, I'm sure you'll get plenty of hits.

G'day
 
I would go looking for a short circuit to earth in the wiring loom in the steering column or under the dashboard, anywhere that the loom passes over bare metal. The described behaviour sounds like a live wire is touching earth, affecting ancillaries. It would not change behaviour of engine unless you managed to fry the computer
 
The most likely point is probably the wiring to wiper controls as you were using these at the time. After that, look to the ignition switch, light controls, horn and cruise control, all of which are mounted where cables need to flex. If nothing obvious there, move onto cables passing through metal brackets near fuse block.
 
As a last resort, try the wiring for trailer plugs which are often fitted after market and often not insulated properly. Similarly if there are any wired after market accessories, look at the insulation on clips, and ensure that the attached wire has been terminated and insulated.
 
Cheers
