Hello
Yes that's what I thought and I believe more and more that it needs this switch on the driver's door armrest (as on the CX3 US) to have the Auto Door Lock.
I continue to search, it allows to discover undocumented functions for the CX3.
I am going to suggest to serglim to add a sheet "SSU CX3" in his table because the functions are not the same as on M3/CX5 (I made tests this morning).
Regards
@mortes :
As I understand it, you have the Auto Door Lock !!!
Can you tell us more? can you join us the FORSCAN backup of IC, RCM, BCMM and SSU?
Thanks in advance.

Wie ich es verstehe, hast du das automatische Türschloss !!!
Kannst du uns mehr erzählen? können Sie uns die Sicherung von IC, RCM, BCMM und SSU anschließen?
Vielen Dank im Voraus.
Hello
The more time passes and the more experiments I do, the more I find undocumented functions on CX3 (EU) but still not Auto Door Lock.
I begin to believe that the function is related to the control switch on the armrest of the driver's door mounted in the CX3 (US).
I am going to question the M2 owners equipped with the Auto Door Lock to know if they also have this switch.
.... and no I am not a "professional", but a passionate amateur

Hello
To help those interested, here is an excel file that allows to change bit by bit the parameters.
This file contains 3 worksheets for IC, BCMM and SSU
The new values are calculated automatically by entering in ORIGIN (B0, B1, .... ) pink cells
Bits can be locked in NEW (bits line) by entering a value of 0 or 1 (pink cells) depending on its own configuration.
For example, BCMM sheet :
If you want to lock Living Home ON (B3 : bit 2=0 and bit 3=1) enter 0 under bit 2 and 1 under bit 3 (pink cells)
The formula (in bit cells : bit 2 et 3) will be erased and will contain your new value for 726-01-01 B1 B2 B3 B4 with living Home ON
The other calculations will remain automatic.
In this case, to return to the original worksheet (without locked bits), close the file without saving and restart the file. The formulas will be restored.
Regards
Hello Axel
Yes we do not have the same original equipment but our common point is the Auto Door Lock Not Equipped (ADL Not Equiped)
In attached file my study completed.
I left on the basis of the "DuyHuynh" Mazda 2 ADL Equiped and on the fact that only 1 IC block (720-02-01) is modifiable by Forscan
I did the calculations to modify my CX3 and yours.
I will also try after January 1st
See you soon.

Hello,
I exploited the IC backup from "DuyHuynh" and i see if i can get something out of it.
Let's be logical ...
1) From what I read in this subject the M2 and the CX3 have the same hardware
2) According to my Forscan IC readings only 4 blocks are modifiable
3) The only modifiable block that is different between "DuyHuynh" auto door lock M2 and my CX3 is: 720-02-01 BAF7 9000 006B
4) When converting to binary I observe that 4 bits are different
I think that by modifying bit by bit block 720-02-01 BAF7 9000 006B
should find one (or those) which activates the auto door lock.
I would like to have the opinion of the experts of the forum.
If someone has a IC backup of a CX3 auto door lock equiped ... thanks in advance
See the attached table.
I'm also in touch with "DuyHuynh" and I'm waiting for its IC configuration.
I have the same username on Mazda3Revolution/Change configuration (explore different functions ASbuilt).
175 pages and not much for us except knowing the manipulation of blocks bit by bit and the coding for M2 "automatic door lock" equiped
Nothing either on cx3forum.com and mazdafrenchclub.com
It would be necessary to find the factory setup AS-BUILT of a Thai CX3 or equipped with "automatic door lock"
Off topic: If you want informations on AIO-Tweaks and the programming of the front parking sensors, I can help you ...

Study in progress for my CX3 :
1) MZD connect and AS-Built are closely related
When modifying a parameter in MZD connect, it changes in AS-Built and inversely.
When i want to write in 726-01-01 a valid value this one is written without error.
see picture.
2) My "MZD connect" (firmware 56.00.513 EU N) does not have a setting for "automatic door-lock".
There is only the time setting of the automatic re-closing doors after opening with the remote (without having opened physically a door).
May be it is necessary to modify "MZD connect " with a tweak to have all the settings of the closing doors as on Mazda 3.
For information : tweaks (AIO-Tweaks) work well on my CX3
3) I have the same problem of writing in the SSU module whith Forscan setting when the function is "Not equiped"...
4) On the Forscan forum it is written that some bit are programmable only once ...
If it is the case for the "automatic door-lock enable" it is unfortunate for us .... because it is written one time in factory...
5) The IC module has only 4 editable lines. If the validation of the automatic door-lock is there, it is in one of these 4 lines that we must see.
That's where I
Hello
Yes i can write in block 726-01-01 when i push the "Write all" button whith the original setup.
Forscan ask to me to confirm writing, i push OK button and Forscan writes without error...
It proves that the writing is not locked in 726-01-01 and that a coherent data is missing to can write new data
I am also searching, but I have an idea ....
I am waiting "M3Revolution-Forum" to compare my data with that of a Mazda 2 equipped with automatic Door lock
I read on "Revo" that Mazda 2 and CX3 have the same hardware ...
Hallo
Mein CX3 hat kein automatisches Türschloss.
Ich bin das gleiche Ergebnis wie du auf meiner 2017 CX3 (Frankreich)
Ich habe wie du, den Fehler zu schreiben nach jedem Versuch, in 726-01-01 zu schreiben
Ich
habe bemerkt, dass jeder neue Wert einen Fehler verursacht, aber wenn
wir das Schreiben (Button Write all) mit den ursprünglichen Werten
erzwingen, schreiben die Blöcke 1 und 2 normal ohne Fehler. Dies ist überraschend und zeigt an, dass das Schreiben in 726-01-01 nicht mit Forscan abgeschlossen ist.
Ich stehe für Tests zur Verfügung.
Hier ist mein ursprüngliches BCMM-Modul und der Fehler beim Schreiben für: Schließen = Fahren; Öffnen = Kontakt Aus
Entschuldigung für die Sprache, aber ich benutze die Google-Übersetzung.
herzlich
