Hello,
Thank you for the question.
FMB001 can receive two parameters from OBD, AVL I/O ID 16(permanent IO elements) and AVL I/O ID 43 (OBD elements). Note that both IO's does not read actual vehicle odometer value.
Device has virtual odometer (AVL I/O ID 16).If Odometer source is set as OBD, and either one of those parameters are read, once the value increase by 1 KM, that value will be added to the virtual odometer and sent through the AVL I/O ID 16 if it's enabled.
Best Regards,
