this is the menu Tristan is referring to, pressing Reset would reveal a new menu. If you don't have Connect software Look at @SergSlim excel file and try a default setting in asbuilt and see if it works.

Here are the diagrams for connecting the parking sensors unit for the M6 from 07/2016.
Parktronic unit GRM8-67UU0

I will connect sensors, with them not as quickly as with the wiring under the torpedo. I hoped that the block would simply display triangles on all sensors, but since it is the block that transmits the signal to ic about the LED on the button, it does not turn on.

Thank you so much for sharing the diagrams, @tirexzed !
I find myself in a similar situation... I own a Mazda 2 (2019) that does not have parking sensors from the factory... I acquired the DH0M67UU0 module, the front and rear sensors, buzzers and the switch, but when I connected it, I could not that work... In my case no new option appears in the CMU... In Forscan, PSM_MZ does not throw any DTCs, unless I set bits B4: b3 = 1 and B4: b2 = 1 to 720-04-16... This throws me in PSM_MZ the DTC U2300 "Incompatible configuration"... As soon as I have time, I will try to try with the bits B4: b1 and B4: b0 in 1, since some of the VINs that @Nikodim shared earlier have that configuration and is not documented

If anyone has other ideas, welcome 😁!

From your original config You have to change only:
720-04-16 B2b2 to =1 or
720-04-16 B2b3b2=11

Those configurations were the ones I tried in the beginning, @Nikodim
720-04-16 B2b2 to = 1 => No DTC, but no new option appears in the CMU, no overlay or anything... Not even sound in the buzzers.
720-04-16 B2b3b2 = 11 => DTC U2300 "Incompatible configuration"

According to my investigation DH0M67UU0 module is equipped only with Rear Parking Sensors, & M2-Skypassion-2019-LHD (3MDDJ6HA60M320665) is equipped with that module. It's diagram can be found at
PARKING SENSOR SYSTEM (WITH C-60 CONNECTOR) [0922-7] with rear parking overlay settings:
720-04-16 B2 b6b5=01 - in case when SCBS-R isn't used,
720-04-16 B2 b6b5=10 - in case when SCBS-R is used.

Also:
720-04-16 B2 b3b2 should remain zeros.
Check also for correct connections, 'cause the buzzer should be functioning anyway irrespective to overlay settings in IC.
Good luck!

Here is another example from a wrecker selling a DH0M67UU0 module from a CX3 (VIN is on page), 720-04-16 B2 b3b2 all zeros.
CX3 Wiring Diagram
Parking Sensor Inspection
As @Nikodim said double check your wiring.

Thank you very much @Nikodim and @craz for your help!
I finally managed to activate them!

The problem was in the bits 720-04-16 B2 b6b5... When they are at 0, regardless of the configuration in 720-04-16 B2 b3b2, the sensors do not work... Not even the buzzers.

After 720-04-16 B2 b6b5 was changed, the sensors immediately started working.

The final configuration I used was

283070


283071

Here it is, the missing element. The SCBS-R setting directly affects the overlay. 720-04-16 B2 b3b2 only work as 0 and 1 respectively. If 1 and 1 also dumps out DTC 2300.
In my configuration, the default is 720-04-16 B2 b6b5 00, since it was not originally parking sensors. In file @SergSlim it is necessary to change the description of the function 720-04-16 B2 b6b5 add the same description as in @Nikodim.
Thus, to activate the parking sensors and obtain an overlay, it is necessary to activate and SCBS-R at least the overlay won't work without it.
Today I will check and unsubscribe.
Thanks @Nikodim for sharing your knowledge.

So I checked @ Nikodim's recommendations.
720-04-16 B2 b6b5 = 01 turns on the overlay, the parking sensors enable button starts working. The IC turns on the button LED. And as I hoped, everything works with triangles on the sensors when overlaid.
Thanks @Nikodim

@SergSlim, please add a description of the values 720-04-16 B2 b6b5 with reference not only to SCBS-R but also to the overlay of parking sensors.

F-BCM:
726-01-01 B3b3=1 - AUTOMATIC Aircon,
726-01-01 B3b3=0 - MANUAL Aircon.

I would be astonished when someone finds it different

Will someone have a backup of a BCMM module with led headlights and active DRL?
I want to see if there are differences to my BCMM (halogen headlights without DRL) and experiment.

I just installed the LED headlights and I want to install the DRL running as original, without connect ACC+ to DRL pin

Edit:
Is there an option related to the DRL in the CMU on this models (M2/CX3)?

My forscan is a Chinese version, so it is not easy to help you.
But the most reliable way is to take pictures with a mobile phone.
No matter how wrong the value you enter, it doesn't seem to cause hardware damage.
At any time, you only need to enter the value taken by the phone to restore it.

I replaced the halogen headlights with LED with ALH on my M6 17 USA. Now DRLs work only when the car is moving. I didn't change anything in BCM, only IC and FSC. Maybe it's different on the M2 and CX-3 ...

It's normal behavior - but not only when moving . If you shift Park to drive and start moving then DRL on until Park again or handbrake on
