Car model and year: 2018 Porsche 991.2
Purpose: activate the PCM Aux input
Porsche diagnostic scanner:
was able to activate the Aux setting without any problems.
Look at the screenshots for X431 ProS Mini activating the Aux input on PCM 4.0
First go to the system PCM/CDR. Search for “Aux”. Select Aux_IN
Change Aux_IN to “On”
I also added a Aux cable to the green connector on the back of my PCM. It connects to Pins 1 (Ground), 2 (Right) and 7 (Left).
Enjoy!
