Product Description

SAE J1939 Pass Through Diagnostic Cables
What Is SAE J1939?
The SAE is the Society of Automotive Engineers, which consists of multiple subcommittees that help determine standards of design for various types of vehicles. The Truck and Bus Control and Communications Subcommittee is responsible for setting standards pertaining to commercial vehicles. This committee developed SAE J1939 and its companion documents as a family of standards that provide a basis of design for ECUs, related devices, and network topology.

J1939 is a set of standards that defines how information is transferred within a CAN to communicate information between ECUs. While a CAN provides a tool for communication, J1939 is a higher-layer protocol that provides a language for communicating using that tool. J1939 is specifically built to work with the CAN model, but codes messages in a way that is standardized for all users of the network, making it easier to communicate data efficiently and effectively.

Product Details


01 Cability now offers a full range of custom SAE (Society of Automotive Engineers) J1939 cable assemblies. Cability J1939 cables are made specifically for the application providing the optimum solution to OEM and aftermarket equipment manufacturers. We do not offer a standard product line to end users.
The J1939 cables are used for interfacing with CAN (Controller Area Network) bus signals on a variety of machinery and vehicles. The CAN bus is engineered to permit microcontrollers and devices to openly communicate without the existence of a host computer. Widely adopted by the diesel engine manufacturing industry to help interface with Electronic Control Units (ECU)


02    We at OBD Diagnostics Inc have developed a software package for use with our OBD2allinone scan tool for J1939 data logging and diagnostics. The J1939 protocol is used for heavy vehicle and industrial applications, and is based on the OBD2 Controller Area Network, CAN, protocol used in all new vehicles.
A few of the myriad uses are:

    diesel powertrain systems
    on and off road gasoline powered vehicles
    liquid natural gas LNG vehicles
    agriculture and forestry machinery ISO 11783
    intra vehicle networking for trucks and buses
    power generation and industrial pumping
    truck-trailer communication
    recreational vehicles
    marine systems NMEA2000
    military vehicles MiLCAN
    fleet management systems

The SAE J1939 standard is the replacement for the older J1708 and J1587 protocols. The J1939 standard defines a huge number of parameters which can be monitored and are referred to by Parameter Group Number or PGN. Below are some examples of our software in use collecting J1939 CAN data on the daily route of a waste collection heavy vehicle.

The real time data available for monitoring and on board diagnostics far exceeds previous standards and replaces outdated systems such as mechanical tachographs. Real time monitoring via telematics and integration with GPS and wireless communication systems allows for complete fleet management and monitoring solutions, all at a very low cost of entry.
