Yes, and that info was eventually helpful. The only problem was that those posts didn't provide a link to the actual pdf (they just mentioned it). After sifting through a million posts on several different subaru sites, I finally got the pdf and all the info I needed. Even then, I had to basically experiment because the pdf guide didn't specify what years/models it pertains to. It also threw me when some people posted the right steps for the late 90's handshake, but they all left out the "warm up the car and drive 12mph" part. That info was in the pdf. Thanks again to all that helped. These forums are a great!

OK... At long last, I FINALLY figured out how to pull the TCU codes on my 97 Impreza OBS!!! I used this pdf guide: http://www.ultimatesubaru.org/forum/attachment.php?attachmentid=1333&d=1091550284 You will however need to know how to perform a couple of ill-described details about the procedure on page 13. 1. What they mean by "connect diagnosis switch to ON" is to plug a ground wire into pin 5 of the TCU diagnostic connector. At least thats the connector for my car, apparently it's different with other years and other models even of the same year! 2. The guide incorrectly tells you to switch the ignition to "OFF", and then move the shift lever to D which is not possible because of the shift lock mechanism. I just turned the Ignition ON, moved it to D, and switched it back to OFF. Then connect the ground to pin 5, switch the ignition to ON again, and follow the rest of the procedure. I got code 24 (duty c solenoid failure), which I was pretty sure of already. Now I just gotta get the driveshaft out until I can get the duty C replacement. Anyone know the best/cheapest place to buy one? Since my clutch pack might be damaged, is it possible to just buy all new components instead of filing down the grooves of the clutch hub? If so, about how much would that stuff cost?

Ok, I tried the described methods to pull the TCM codes but nothing works on my 97 IOBS. My 6 pin connector only has pins 1,2, and 5 populated (missing 4 that the directions call for). I tried those, but they do nothing, except the first 2 make the ABS/Airbag light flash. Does anyone know of anything else I could try? I just need the specific procedure for my 87 IOBS i guess. Also, any idea what the male and female green connectors are for? Thanks

Thanks for the very useful info. I will definitely get a scanner soon for the CE light, for now it's the binding issue. I need to get down there and remove the driveshaft real soon.

Thanks for the reply. Yea, I've read up a lot on torque binding. It's just a matter of figuring out the best route to take towards fixing it. Putting a fuse in the FWD slot did nothing, and there is also no AWD light that is supposed to come on (Not sue with my 97 IOBS though). I've read mixed things about OBDII scanner not reading at all on some cars, especially pre 98, so thats why I'd rather try to use the handshake that OB99W just showed me. As far as removing the driveshaft, can you give me more details as to which part to remove exactly. I'll look around for a post with some pics. Would that involve draining any fluid or oil? Also, would I need to somehow seal any exposed components? Thanks

Thanks OB99W, thats exactly the info I was looking for! I had found other posts like this, but none as detailed and specific to my car.

wrong forum, sorry.

Hi, I've looked all around the forums and still can't find a cohesive explanation as to how to pull codes from my TCU and ECU without an OBD scanner. Some posts are outdated and missing images or have dead links. Can anyone explain to me how to use the green/black connectors with the 2 ground jumper wires? As far as details, I've had the car for 4 months and it has about 170K miles on it. It has bad torque binding when making slow turns, and the AT Oil Temp light has always flashed on startup. The last few months the check engine light has been on. I don't know much about the history of the car, but the engine is in top running condition. The transmission seems to shift pretty well, but it feels like the AWD system is causing some intermittent hesitation while accelerating from a standstill. The trans. fluid looks decent and doesn't seem burnt. I'm torn between whether or not to change it or not, since it may have never been changed. Seems like I might need a new duty C, but I'd like to know the specifics so as to avoid replacing unnecessary things and/or skipping over things that definitely need replacing. Any help would be much appreciated! Thanks
