Default Mazda cx5 2018

Hello guys I try to open the options Auto door lock from R_BCM with ForScan .
Someone can help me to open it ? Because i change something and the auto lock working without the screen , And it works for me but two warning lights came on, so it probably doesn't support EU, can someone please give me a code that will work? Many thanks to the helpers…

Is the image the default RBCM asBuilt ? Post the changes you've made. In order to reveal the hidden menu you need to press RESET with IGN ON.

The photo i upload it’s my original code , in my car I don’t have the option in screen to do the auto lock . This is why I want to know what I need to change for get it . And it will be work to my Mazda cx5 2018 EU Version

Before I use some code i don’t remember, but its was work But it gave me warning lights on the side of the car so I don't really want it. I'm looking for a code that will work on my car and won't give me warning lights.

If you are getting warning lights when you use FORScan to change your settings, you likely have a Mazda system software issue that needs to be addressed (corrupted needs a reboot and/or latest update)
You should get the correct software upload for your vehicle instead of trying to use FORScan to do it or you will most likely get the same warning lights.

You probably didn't understand correctly. I tried using the Mazda 3 coding. I'm trying to perform automatic locking on EU versions. There's no option on the screen. I'm looking for someone who can explain to me how to activate it. I don't know how to do it. That's why I uploaded a picture of the R-BCM so you can explain to me what needs to be changed. I'm looking for people with experience.

I understood that I need to change a few things in R_BcM and it works, but I don't know what changes need to be made and what needs to be written instead..

Modify RBCM as-Built exactly like I draw. After your changes are correctly coded and your car restarted, with IGN ON go to infotainment and press RESET (see pict I posted earlier), and the hidden menu should appear in "Auto Lock Door Mode"
This should work unless you happened to live in one of the region of the world where auto door lock is prohibited.

As Mazdaon pointed out, from what I've read the EU version of Mazda do not have the auto door lock function found in the USA versions.

I have an aftermarket head unit, so I cannot access the Infotainment menus. Am I out of luck?

No, you aren't.
Set the mode in HEX you'd preferred in line 7B7-02-01 (B0), right now your car is set to N/A (0x00)
Automatic Door Lock Mode
N/A
OFF
Lock: When driving
Lock: When driving / Unlock: IGN Off
Lock: Shifting Out of Park
Lock: Out of Park / Unlock: In Park
Lock: When driving / Unlock: in Park
