Alarm sounds when door opened

I installed an FMM130 and a CAN Control Adapter on a MA Polo (Brazilian Model). Two relays were installed in DOUT1 and DOUT2 of the FMM130 to lock and unlock doors. However, when the doors are opened, the alarm starts to sound. The alarm arms when the doors are locked.
Anyway to fix this?

Hi Mowasa,

Good day, this maybe because of the security features of the vehicle, to control the door using DOUT, better to contact the vehicle manufacturer support department to check if your wiring is correct.

Or you can create an HD ticket or contact your sales manager.

If you don’t have any contact with our Sales managers, please contact them on our official website and click on the “Contact Us” button. When you click, please fill out the form and submit it. Note: as a topic, please choose “Vehicle telematics”. Or you can send an e-mail with a description of your situation to
