Porsche Cayenne Trailer Controller

[kostelectronics]

Hi@all,

I have a 2006 Porsce Cayenne here with a traier prblem -->The lights at the trailer are flickering and the Trailer CU does't respond to my diagnostic-tool (Autel MaxiSys 906 BT). Also the motorized Trailer-Hitch does not working.
Does anybody have a pinout of the Trailer-Controller (7L907383F) or can help me to fix the Trailer-Controller? I'm a electrician, but without Scematic-Diagram, it's not so easy. As far i can see, all Voltages inside the Controller are correct (5V for the Processor, etc..).
