Hi Everyone,

New to the community, will appreciate some help.
EUDM Outback '03 BH9 EJ251 E-4AT OBD2.

Planing on 6k km round trip to Spain with my wife and kids. Car runs good, no CEL or other lights. However, decided to double check by reading DTC from both ECU and TCU.

Tried to connect with FreeSSM. It will not read my ECU, but it will read the TCU. Shows no trouble codes, both current and historic.
Then used RomRaider to see if it will connect with the ECU, and it did. Reading ECU shows no temporary and no memorized DTC.
However, reading TCU shows a bunch of temporary DTC, which seem to change every once in while. Last screenshot I made is attached.

Should I be worried? Gears change fine (I think..), tranny makes no noise, changed almost 8l oil about 10k km ago - used expensive RedLine stuff.

Many thanks!

FreeSSM tells truth for MY03 EDM. Confirmed.

OK then, will ignore the temporary DTC from RR, thanks.
I was thinking of performing TCU reset, just to see if they will go away. But then I read that new learning will take some time and it might be a bit tricky.
