The first script I uploaded above was not very advanced and would be something easy to do manually (as hellow said).

I created another one which I find much more useful. For this, you tell it what feature you are looking for (e.g. lkas), and then you give it a bunch of .AB files and tell it whether each one is for a car that has that feature or not. Then it goes through all the modules and compares the individual bits between the .AB files. It tries to find the bits that are consistently set to the same value for all cars with that feature, but are different for cars without that feature. In the end it prints out the bits it thinks are related to that feature as 1 and the others that it thinks are not related as 0.

With python scripts you normally need to install python and run it through the command prompt. Since not everyone is familiar with that I made this one an .exe that you can use.

Let me know if it is useful and if you have any suggestions.

EDIT: See post below for updated version. This one contains a bug that causes it to crash when two AB files have a different length of AB data.

I got the message from Win10, that I do not have access to the *.exe and AVIRA (Antivirus) quarantined the *.exe:

It is a false positive. Probably due to the program I used to convert the python file to an exe. Try the new version attached. It is built using a slightly older version of the program I used before since it seems to be detected less by anti-virus softwares. I assure you it doesn't have any viruses in it haha.

(Also it contains a bug fix that caused the program to crash in some cases.)

Hi guys! I have Mazda 6 2019 with SCBS-F and I can't enable LKA and LDWS. I have in menu LKA but it doesn't work at all. Btw I managed to enable HBC. That's what I have changed:

The EPS module in your car likely does not support LKA CAN messages since your car didn't come with that feature, so most likely you're not going to be able to enable LKA. Although, you may be able to enable LDWS tho with audio alert only (no vibration).

You can try these, they are based on values for my car (which is a 2018 Mazda 6). You might get DTCs since I also have LKA.

Thank you! I will try it tomorrow. Btw I can see in EPS that I have LAS_CUR. I believe there is a chance to enable it

Oh ok, that's great. Disregard what I said earlier, it should work.

Some additional notes before you try what I posted above:
  • I also just noticed that I also have 706-02-02 8495 sometimes. I think that value is related to your current LKA settings, so you don't have to change that.
  • If your car has TSR, then use 706-01-02 84A8-0000-205C instead.
  • If your car has parking sensors or SCBS-R, then modify the 720-04-16 I posted above based on the spreadsheet by SergSlim. (just B2). (You might have to also modify it if you have DAA).
Let me know how it goes. If it doesn't work, please share your original asbuilt data for IC/FSC.

Could you also please do me a favor since you seem to have the LKA menu. Can you compare how your IC and FSC data change when you change the Intervention Timing setting in the LKA menu.

Sure, so the first one is for early intervention and the second one for late:

I don't understand what I did wrong but LKA didn't work...When my windscreen was dirty there were two indications on the panel like HBC and SCBS-F was orange but there wasn't LKA. I attached my initial config
