Good day. Thank you for your question.
Your understanding about CAN-CONTROL is correct, but also take note of the supported vehicle list for certain parameters - https://wiki.teltonika-gps.com/view/CAN-CONTROL#Supported_vehicles_list
As for the FMB130 DOUT's, yes they can be used for the Door Open and Close function with the assistance of the SMS/GPRS command. Kindly try it and if you are experiencing any difficulties, please reach out to us via VIP Helpdesk or contact your Sales Manager/Distributor.
If you don't have any contacts with our Sales managers, please contact them on our official website https://teltonika-gps.com/
and click on the "Contact Us" button. When you will click, please fill the form and submit it.
Note: as a topic, please choose "Vehicle telematics" or you can send an e-mail with the description of your situation to firstname.lastname@example.org
Thank you for your understanding.
