Finally I got some results, not much but at least something to analize

When I communicate with the TCU I get back this repeated:

"TX>45C00000<TX
(00)(00)?(00)p?(00)p?(00)p?(00)p?(00)p?(00)p?(00)p ?(00)p?(00)p?(00)p?(00)p?(00)p?(00)p?(00)p?(00)p?( 00)p?(00)p?(00)p?(00)p?(00)p?(00)p?"


When I communicate with the Air Conditioner I get back this repeated:

"TX>890002<TX
(00)(02)*(00)(02)*(00)(02)*(00)(02)*(00)(02)*(00)( 02)*(00)(02)*(00)(02)*(00)(02)*(00)(02)*(00)(02)*( 00)(02)?(00)(02)*(00)(02)*(00)"

When I try to communicate with the ECU I get back this ONCE:

"?
TX>78123400<TX"

and the same everytime I hit enter.

I don't understand any of this at all so please advice.
Thanks again in advance
