Telematics data, including location, speed, fault codes, engine hours, computer engine diagnostics, and other vital vehicle health data is read through a vehicle’s onboard computer. This information is accessed and transmitted through IoT technology via GPS and cellular trackers.

Telematics Interfaces

Modern vehicles all contain various computers and an Engine Control Unit (ECU) that controls the engine and various aspects of the vehicle. These computers also contain a wealth of maintenance and diagnostic information than can be read via various standardized plug-in interfaces.

Tenna Fleet Tracker

The Tenna 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 Tenna Fleet Tracker also transmits telematics data including location, speed, fault codes, engine hours and other important diagnostic information.

OBD II Connector

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.

JBUS Connector

Heavy-duty vehicles over 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.
