Hello, I have already asked the question in the Kia group, since nobody could help me up to now. The following problem: I have a Sorento, Diesel, UM from 2019 with original AHK, changed from a VW Tiguan. Dauerplus was also put in Kia, as it should be on Pin9. I measured on Pin9 also 12.2 volts with switched off ignition. In my caravan an ATC is installed, which is powered by Pin9. Other customers work over permanent plus. Only the ATC wi ll not. A test with another car was positive, the ATC worked, as well as with the old car. What could be the reason that the ATC did not work with Sorento? I have even laid a bridge from Pin9 to 10 to exclude the ATC from being 10.
