Tenna Fleet Tracker
The Tenna Fleet Tracker helps manage your Fleet vehicles and trucks by reading diagnostic info from vehicle Engine Control Unit (ECU). The Fleet Tracker is designed to plug into a the standard OBD II or JBUS vehicle interface. In addition to transmitting live data GPS location information over a cellular network connection, the Fleet Tracker also transmits telematics data including speed, fault codes, engine hours and other important diagnostic information.
A vehicles’ computerized diagnostic and reporting is known as On-board diagnostics (OBD). Today, all consumer vehicles are required by law to have an OBD interface. The OBD-II specification is what is in use in most automobiles today. OBD-II can be accessed via a specific 16-pin connector which is also standardized under SAE J1962.
Heavy-duty vehicles utilize J-BUS, sometimes referred to as the Modbus protocol, for vehicle diagnostics. J-BUS devices are typically accessed with one of two connectors – a 6-pin J1708 or a 9-pin J1939.
