This paper describes a case study led by Science Applications International Corporation (SAIC) of Dayton, OH USA and Dearborn Group Inc. to prove the feasibility of employing Telematics technologies to the vehicle test and measurement industry. Many test functions can be automated through the use of secure wireless technologies. For example, vehicle data can be dynamically monitored on the vehicle and data meeting pre-determined criteria could be downloaded via the wireless communications center. Additionally, central, real-time wireless monitoring of vehicle fleets provides the vehicle fleet manager with the ability to manage multiple tests simultaneously, thus improving efficiencies and potentially reducing manpower costs and compressing test schedules.

This paper describes the new Recommended Practice SAE J1939 (High Speed Communications Protocol for On-Road Heavy Vehicles) and the development and application of this protocol for off-road vehicles such as agricultural machines and construction equipment. This paper will review the work of ISO committees in the development of an international standard for vehicle high speed communication systems. The proposed use of SAE J1939 and the CAN protocol for Class C (high speed) network communications on Off-Road Vehicles is also reviewed.
