I have searched the VIN and called the dealer as well as SOA and none of which applies to my vehicle. I have seen the talks on here of years and it would make sense that I'm having trouble with the harness. However it's not the harness going into the the 580, it's the one going from the tcm to the VB that my diagnostic charts point to as having faulty wires, open circuits, high resistance etc.

 

 

Sounds like you need to advise us of what year model and engine type (2.5, 2.5 turbo, 3.0 or 3.6) your vehicle is so that we can give you relevant advice.

If you are not after information for your vehicle you will need to advise what information you want and for what transmission.

The title of this thread is TR580 and you are now referring to the 690 which has been used in two different versions/generations of Outback.

Let's start from the bottom.

Year, Engine, Fault Codes

2010 and 2011 usdm Outbacks had the TR690.
2012 up it depended on a number of factors whether you got the TR580 or 690.

It's a 2014 outback 2.5 limited with the 2nd gen 580 cvt.
I think I figured my problem out by mapping more and ohming it out. My main concern is not having the diag flow chart for the 580 wire harness. The one I was working with appears to be for a different one. I no longer have wiring issues now that I've traced it out and wrote it all down but I have one solenoid reading 1k ohms so I have to replace it.

Originally I had p2763 code for lockup duty high
Replaced, then had a slew of codes appear
P0700, 2799, among others like shift solenoid A high, shift solenoid B high, control circuit high etc...
I fixed my wiring issues (the first flow chart stated pin 26 on the b54 harness is the lockup duty- pin 2 on the b11 plug) I ran a new wire going from pin 26 on the b54 to pin 2 on b11.
I realized now that b11 plug does not exist as what I'm looking at on thexa valve body cover has wayyyy less pins and wires. Also i should note pin 26 on the b54 does not seem to control the lockup solenoid. The 580 appears to have one less solenoid than the 690 as well. So I was confused for the longest, until I mapped it all out.
I have undid the wire I ran and put it all back as it was.
I have now 3 solenoids reading 11.5 ohms, my temp sensor reading 4k ohms (30° outside), two solenoids reading 5 ohms which should be normal if they go to the ones on the side, and one final solenoid reading 1k ohms which I believe is the problematic one.
If I had a diagram for the 580 I could determine what wires go to which solenoids and if they are in spec. Clearly the 1k ohm one is out of spec, but I would rather not open the cover again unless I need to in order to trace those wires and find out which solenoids go to what color wire on the inside amd which one is faulty.
I currently am having a bunch of codes for the same high circuit readings. Shift A and B etc.

 

 

Your amazing! Thank you very much. No idea where you got this but it explains all my problems.

 

You're welcome.

I'm crafty like that. 🤪

 

@cardoc Well here's my update. I have replaced the AWD solenoid and the LOCKUP solenoid. I have also don't a fluid swap. The car has been smooth and reactive for two days and now I have a p0700 code set and a p2762 code set. It is struggling uphill now. Does not shift when it should, and when accelerating from a stop it stalls some, and makes an sound to which I could only describe as something not fully engaging. I let off the gas and then slowly accelerate and it moves. It's back to being parked now until I can fully understand what exactly is going on. The ohm readings all look okay however they are kind of low, when everything's cold. This is my wifes daily driver and I would just about do anything at this point to fix it. 🙄
