I wanted to change the middle console module for a one with a "sport" button but I couldn't find any information if the middle console module in both variants (with parking radar and with "sport") has the same circuit - is this only a matter of a sign on a button and activating the right option in cars ECU or it is needed to change button module to be able to activate "sport" button?
I bought a middle module with "sport" and did a short investigation, here is the disassembled module:
Here is connector with pin numbers which I assumed:
And here is a reverse-engineered circuit diagram:
Safety related features in a car have additional diagnostics. Sport button is safety related because of influence on cars traction and for this reason there is additional 1k resistor across the switch so ECU can detect if the button connected correctly. If button is missing then most probably ECU will switch off this potentially dangerous sport mode. Door lock button and hazard lights can't directly cause a harm and they don't have this additional 1k resistor.
I didn't took the regular module without sport button yet but I will put here a circuit diagram and circuit comparison when I do this.
