Parking sensors

[IMAY2023]

First of all, PIN 72 is the right side and not left. Check the grounding.  
The two new rear sensors on the side are only activated when Semi-Automatic parking is enabled with the combination of all 12 sensors (front and back). If the fronts are faulty, none of them works if you put the setting to " Semi-Automatic parking" 
You might misconnected the pins. See the diagramd.
