Currently I'm investigating on Mazda 2/CX3 BCM ASBuilt. I need more AsBuilt data from FORScan to build the template with all options.
I'm pretty sure wich bits are related to autodoorlock and other options.

Thanks to all!
Door lock in Mazda 2 control by Module 726 and it not display in asbuilt.

so you just use Forscan to read inside your car only.
 
I tried this configuration for auto locks door for my 2015 CX5, It it working but it never appear Locks door mode option on CMU. So when driving it will lock and unlock when ignition off.
to make it appear on your screen settings,go into vehicle settings choose door lock and reset that screen. your new door lock options should appear on that screen.it worked on my mazda 3.

What do you mean by "reset that screen"??? I have similar problem on M3 Sedan.....

How did you reset screen??

Ok I got it! ? sorry for dumb question but I never used that function! ?
 
Tell us your VIN , We will try to help !

And if you want to DIY , you will need a modified ELM327 or something can read/write your RBCM !
Hi Lewis-Liu,

sorry for the late reply, i was away for sometime. i have attached the photo of the label beside driver's door. hope it is useful.
I have got a ELM327 with MS_CAN selector switch. i did follow the instruction to change the code for auto_lock, but somehow it seems like switching off some other features....

let me know how i can upload my RBCM data.

Can you post your IC AsBuilt? Forscan returns "incompatible blocks" when I try to write this values on BCMM. Thanks.
 
The parameter above I took it from my car(mazda2).
After I changed the value in Mazda Connect, I read the data in IC by Forscan and wrote down.

Please try to change one by one.
IC is another module, 720, not 726 BCMM.

I think BCMM AsBuilt stores only custom settings. Please, read the Instrument Cluster AsBuilt and post it. Thanks.
