Support for Outback 2012 RT690 TCU with SSM

[mkajola2]

Hello,
As some discussions I googled said, FreeSSM with VAG interface does not support TCU in 2012 Outback (I have TR690 CVT).
I tried this in debug mode, and noticed that the TCU replies, but the length of the reply is 77 bytes and does not match any of the expected lengths in GetCUdata(), and thus connection is newer established.
Modding the code a bit I was able to read the diagnostic codes.
However, seems that there are no mapping from the addresses to the actual Pxxxx codes, which makes interpreting quite difficult.
The responses 0x1C1/0x1C7 Bit6 and 0x1C4/0x1CA Bit 7, look quite reasonable, so I think they come from the TCU.
Can the TCO mappings be found from somewhere?
I could try to augment the code, and it that succeeds, raise a pull request.
