AIRBORNE PARTICULATE MATTER SENSOR (APMS)

I checked the wiring it's pretty simple.  It is actually connected to CEM and not the CCM as I thought.

The question is that Does the HVAC require something additional like a cleaner or different filter?

Here is an update on this. It turns out there has been some changes on the wiring. up to MY21 the PIN 15 on CEM IP socket does not exists.  
The AIRBORNE PARTICULATE MATTER SENSOR (APMS) shares the same LIN as wireless phone charger for models at up to MY22.  According to MY23/24 diagrams, the wireless charger is on CEM FL socket PIN 41.  
I connected the sensor to PIN41 but could not get it to work.  I check the LIN output voltage on the sensor which is around 9 Volts. 
Enabled the AIRBORNE PARTICULATE MATTER SENSOR settings and did not get any DTCs from CEM.  From the ECU tools I tried to read the data from sensor but it says no signal is received. 
So, either the sensor is faulty or the PIN FL41 is not correct for MY19 models. 
Does anyone know what is the correct PIN number for MY19 to 21 ?  
This is the VIN number that the part came from.  7JR102FK5MG094609. Maybe someone with VIDA subscription can tell me.
