If you want to put a switch on, why not figure out the wiring going to the actual transfer case, instead of the fuse box? There must be powere supplied to some actuator that does teh actual engagement., Cut the power to that, and it should diable the FWD, without all the other issues (unless that due to diagnostics triggerering all the other stuff, like wipers). Haven't looked into this at all ... just off the top of my head

There was a popular mod (it was popular for about a week) where people were modifying their light switch to allow the already wired rear fogs to work. The "blank" located on the light switch was turned into a switch (although it did not light up) and people were now able to use the rear fogs not intended for the U.S.
Here's a pic and a link to that popular mod: http://www.e90post.com/forums/showth...ear+fog+lights Now that I've set the stage here's what I want. Let's do that "mod" but with one of the buttons on the lower console (see pic) for this AWD to RWD switch. I'm not sure it the buttons will work the same as the fog light mod but it does give us a great location since this spot is not used. Also, I want someone to set it up so that it's on a relay system so it resets back to normal when the car is turned off. With all options from left to right: - Driver heated seat - PDC control (for front PDC, rear is automatic and doesn't require a button) - Rear roller sunblind/visor - Hill Descent Control (x drive only) - BLANK - Passenger heated seat |

Although I admit I have not read this entire thread, I'd like to add this bit of info. My situation is different in that currently my xdive system is not working (I think it's the transfer case servo motor that is toast on mine, BT error says something like transfer case - clutch position unknown). Anyway, I've been driving aorund in 2wd for about 6 months. ABS, DSC, cruise, and 4x4 don't work. Everything else works fine (wipers, brake lights, speedo, odo, etc.). I've got a few codes thrown. Those codes can be cleared using Bav Tech. If someone is really adventurous, you could splice into transfer case wiring that goes to the servo motor and put your switch in there. Not advocating that at all, but just thought I'd throw that out there. Not sure what that would do about errors, etc., but my xdrive hasn't worked for months but everything else (other than Christmas tree error lights) is fine. Just Fyi.

And I wouldn't keep clearing those codes. Your car needs to know there's something wrong all the time. If you clear them, your car will try to operate normally at start up. Those codes are thrown because something is wrong and without theses codes your car may try to activate other components related to the faulty system and could damage them aswell. |

Oh, btw, I checked as much as I can through coding and couldn't find anything related that could be useful... It would have been too good to be true... Coding awd for winter and rwd for summer

I would love for the fuse to operate all of the controls except the AWD module. I'm thinking about making a switch, but am very hesitant |

Ya I would SO not mess with that unless I had access to a basically scrap car on which I was willing to mess around. Maybe it's safe, but who knows with these uber fancy mobiles. Heh.

There is a lot of interesting thing to look in the BDSC module... None that are what we are looking exactly, but with some tests... |

Haven't read all 8 pages but you CANNOT make an STI 100% RWD, ever. The only way would be to remove the front driveshaft like the drift cars.
DCCD: 41/59 f/r (Full open) this is how the car is normally to (manual mode can adjust the torque to be more even, 5 degrees of increased Front bias) 50/50 f/r (Full lock) |

Aren't we waiting for Burger or Cobb to do some code writing and make a "map" for us?

Someone on here has been having a probably with their servo motor in the transfer case and has been running 2wd for a few months. He reported ^no problems.
I personally don't see how this would damage the car. If the front diff never engages (after pulling the fuse, car off) how can it damage it? The front diff is disengaged when the car is off anyway. |

Wow, read the entire thread to make sure I didn't miss something.
Here's what I think. Install a switch, as others have suggested, to turn off the transfer case, one wire, probably a 12volt lead. Then the TC will get signals but will not be able to engage. The car will be a 2wd car with all the other traction control stuff working. Turn off the DTC, as we all know how to do. Voila! All that pulling fuses talk is like turning off the main breaker of your house to turn off the tv. Last edited by 4corners; 04-17-2011 at 09:26 PM.. |
