I did a little research and found a Suzuki technician training document that explains the entire transfer case operating logic.
The buttons control the actuator, which indicates its position to the 4WD control unit based on the rotation performed. Two switches on the forks, confirming the position, turn on the dashboard lights and activate the pneumatic hub locks. The 4WD control unit, in turn, communicates with the ECU and the ABS/ESC.
If certain conditions are not met, the system does not activate and stores the errors, which can be read by counting the flashes of the light in DTC check mode.
Here is the link to the document (even though it is publicly accessible, it is still confidential material, so moderators are free to remove it if publication is not permitted):

Now my question is: using a lever-type transfer case, how do I make the 4WD control unit understand that the actuator position is valid if the actuator is no longer present?
I could remove the actuator from the transfer case and place it in a protected location, keeping it connected, and manipulate the ground signals that the transfer case switches send to the 4WD control module.
Or, premising that I'm absolutely no computer expert, I was thinking of an emulator/controller based on Arduino, that could send the signals and values needed to operate the 4WD system without the necessary components being present. Could it be possible?
