SAE J1939 is the vehicle bus standard used for communication and diagnostics among vehicle components. Based on the same architecture FMS protocol dedicated to telematics systems is available. It has certain standardized parameters available, such as fuel consumption, engine work-hours, etc. Please visit http://www.fms-standard.com/ for more information and message structure.

To check if any Tell Tale parameters are available via FMS on your vehicle '''scanfms''' SMS/GPRS command can be used. If there is any parameters available on FMS this means that Tell Tale status is available as well. Response will show parameters that are available on vehicle, but it does not include all Tell Tale statuses - only  MIL indication is implemented see [[FMB640_Teltonika_Data_Sending_Parameters_ID#FMS_elements|FMS elements]]. How to parse scanfms response can be found in wiki [[FMB_scanfms]] page.
