Default Why is my DCCD light blinking green?

Ok, all I did was change out my steering rack bushings yesterday. Afterward when I got into the car I noticed a green light blinking. Those indicator lights that go vertically on the instrument cluster that change color from green to orange to red I think. They change when you put the DCCD in manual mode and adjust manually. Well the green light at the bottom of the cluster(which is green) is continously blinking. I checked underneath today and couldn't see any problems. Anyone know what might have happened? Should I just take it to the dealer?

its a code, i guess like a check engine light. go to autozone plug in a obd scanner. long blinks are 1.2 sec. (signifies incriments of 10) and short ones are .2 sec (signifies incriments of 1)

ex. long, long, short, short, short would be code 23

I don't think it's a check engine light. It's the bottom arrow that blinks green. When it's a CEL isn't it the check engine light that blinks? It doesn't blink in any special pattern, it's like a turn signal blink. I don't know. The AP says there ar no codes.

Are you referring to the green circle '0' which normally indicates 'open' when the DCCD is manual mode. The subaru manual indicates that this light will flash if there is a problem with the DCCD.

on the 04, the dccd trouble code could be pulled by the following procedure:
engage parking brake
turn ignition to on
set dccd to min
fully depress throttle
turn dccd dial fully to max, then back to min. repeat this 10 times
It will flash 2x/sec if there is no trouble code
If there is a trouble code, a 1.2 s flash indicates a 10 digit, and a .2s flash is a 1 digit. So 1.2, 1.2, .2, .2 would be a 22
diagnostic procedure:
1: engage parking brake
2: set dial to min
3: start engine
4: set dial to max
5: release parking brake
6: set dial to min
7: engage parking brake
8: repeat 4-7 twice in 30 seconds
(will now get a trouble code display)
9: operate parking brake
10: operate brake pedal
11: operate manual mode
12: operate dial and set to max, wait 3 seconds
13: drive above 10mph for at least 5 seconds and check the indicator status light
At this point if the system is happy the next ignition cycle will clear the dccd trouble code
There are only 7 dccd codes, 11, 12, 13,14, 21, 22, 23. Rear diff sensor is not a trouble code, just an override condition that will clear as soon as temp is ok.

I think that blinking light might have to do with more than your DCCD. I had a short in my rear O2 sensor 2 weeks ago and it blew a fuse. The bottom light on the DCCD started blinking just as you described. Replaced the fuse & the DCCD light stopped blinking. Perhaps something shorted out?

Thanks, I'll think I'll check the fuses first!

They told me it was a steering position sensor and replaced it without question

Default Re: Why is my DCCD light blinking green?

I just did the WL steering rack bushing and am now getting this blinking DCCD light along with an airbag light (?!?). This has been a horrible install--two stripped holes on the steering rack and now this. This has consumed most of my weekend.

I've been searching on a few forums looking for this--can't seem to get a definitive answer...anyone have any ideas? Going to try and get an appointment with the dealer tomorrow.

Edit: re-flashed back to stock ROM (from gabe's Stg0 R1) and am now getting a CEL along with the above mentioned lights. Car's at the dealer right now. $95 diagnosis fee (free if under warranty). Don't think it's related to the R1 ROM, but I wanted to post for comments.

Edit2: Got word back from the dealer...bad clock spring...caused by me. $450 parts/labor. CEL was from me leaving the green connectors in after re-flashing. I feel like a dumbazz for both issues.
