Default 06' Aftermarket Steering Wheel Install: IMPORTANT INFORMATION

EDIT: FOLLOW ALL OF MY PICTURES AND POSTS TO THE SOLUTION IN POST #10

HOPE THIS HELPS ANYONE WITH AN 06' STI



I tried to throw out a title that would spark more interest and help.

I just installed an aftermarket steering wheel. (flame suit on, no discussion of airbag safety please...thanks..)

I have the horn circuit powered through the #1pin in the B68 connector. This connector powered the horns and some of the cruise control switching. No biggy.

I disconnected the other two connectors related to the Steering Roll Connector to remove it for the hub install.

The second connector removed was #AB21. It is for the airbag on the driver's side, yellow in color, 4 pole and not needed for the new wheel. (I think...)

There is a third connector. It is a 4 pole and white in color as I remember right now. (If someone could help with that it would be apppreciated) Anyway, this one is disconnected also and the steering roll connector is completely removed.

I used this install guide:http://forums.nasioc.com/forums/show....php?t=1139576

Now my DCCD controls do not work and the DCCD is stuck running mechanically ( in full open) with no help from the car's electonics.

I have been, and will continue to, peruse the Service Manual for Wiring but could still use some help in my panic-stricken state here at work.

Thanks for any input.

Come on guys! I did my research. I bought the damn book. I have a 4 pin mystery connector that leads into the stupid clock spring assembly. Out of all the bench racers, real racers, and weekend warriors on here somone has to know something.

Its a 4 pole/pin white connector, possibly the B426 - steering angle sensor blue/grey, black/grey, white/grey, red/grey wires...

Its in the harness, just under the steering column, next to B68 and the stupid airbag connector..

Hey thanks! ^

Here are some pics of the culprit. (I think) I have not verified for sure as I was busy with family stuff last night. I tore this open and it contains two gears and a small PCB with contacts on it. This must be the Steering Angle Sensor for the Yaw Rate and Lateral G Senso in the DCCD. I will do a full edit/write-up and How To when I know for sure.
Obviously the wire colors listed in the digram do not match. This is my dilemma at this point. All I can do is plug it back in and power the car up to know for sure.

My best guess right now is that the Works Bell Hub integrates with the clock/spring and steering angle sensor assembly. aka: steering roll connector.
The NRG hub takes some modification to be used. (Check the first link above on how I got the horn working...) I'm not too thrilled with that but it works and it is hidden.

I will not be able to check out the solution until Thurs. or Fri as I am busy with some real estate stuff.

How much do those Works Bell units cost? I can always slap this all back in if they are a bolt on. Funding is thin right now though with fuel at $4.31/gal.


Almost forgot to thank you guys.

BUMP!

I figured it all out thanks to my handy Subaru "2006 Service Manual Wiring Section" and a little testihng in the garage.

The pictures above are of the "Steering Angle Sensor". It is attached to the "backside" of the clock-spring assembly (yellow wire and connector).

The "SAS" sends feedback to the Yaw Rate & Lateral G Sensor for the DCCD. It is also connected to the DCCD switch circuit.

Removing the "SAS" for an aftermarket wheel install renders your 2006 DCCD useless. It will simply sit in the full-open position.

After hours of messing around and studying wiring diagrams I can honestly tell anyone with an 06' that removing the "SAS" is a poor idea. You might as well cut your springs with a hacksaw and put wire wheels on the car.

Purchase a hub that utilizes the existing componants of the column and you will be fine.

so you're good now? The works bell hub is so much nicer than the nrg one, i've had both. THe nrg leaves a little gap around the column and doesn't look as nice IMO.

Well, our mutual friend sent me the Works Bell and that is all good. I need to buy another steering roll connector from Subaru now. ($189 for the clock spring and who knows how much for the steering angle sensor...)
After plugging my "old" steering angle sensor back in and installing the WB hub, the DCCD is still dead in full-open.
I havent' had time to chase down what it might be but, I thinks that maybe there is still a part of the airbag circuit that ties in to the DCCD.
I tried ECU resets, all the fuses, pluggig it in dead/hot whatever...the DCCD is still dead.
Time to throw more money at it I guess...
When I finally do figure out this thing, I'll do a full write up.

Grambo..... I currently am having the same problem with my 06. Bought the car with a sparco wheel and the DCCD isn't working. If you could help me with getting this thing re wired i would greatly appreciate it. Frustration has definately set in....

Just read through this:


In that case, installing a faster steering rack or quickener will affect the performance of the DCCD. Interesting.
