I'm aware of the diagnostic procedure for the ECU using the connections under the steering wheel (the black and the green ones). What I wanted to know is, is there a way to check the auto box in a similar way?
Perhaps through moving the stick through certain gears while turning the key etc. etc.?
BTW, this is for a 1996 Subaru Liberty GX.
Also, with the ECU diagnostic, both with the normal black connections and the green drive connectors, all i get is the Engine Check Light flashing repeatably on a fast cycle with no slow flashes or breaks. Does this mean no codes?
Two other questions too. What could be making the white build-up on these hoses:
And, what could this button I'm holding be for? It is found under the steering column and a wire leads from it to the box you can see behind my hand.:
