Product Description

J1939M Type II to molded Molex 43025 A
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.


03  J1939 Cable - Manufacturing Solution
Since we manufacture our cables to meet your specific product requirements, we can supply a virtually unlimited variety of J1939 cable configurations and pin-outs. Our engineering staff is readily available to assist in designing a solution to meet your demands. Send us your engineering specifications and we will be happy to accommodate your needs. Our injection molding capability means we can supply you over-molded connectors that ensure rugged environmental performance and a professional appearance.

Product Applications

the SAE J1939 cable can be found in a number of diesel powered applications including diesel trucks, buses, on-road vehicles, off-road vehicles, marine propulsion, power generation, and industrial pumping. In the automotive industry the ECU can handle a variety of subsystems throughout the vehicle with the largest being the engine control unit and others including transmission, airbags, antilock brakes/ABS, cruise control, and more. Your J1939 custom cable will provide a solid and reliable connection to your specific CAN bus delivering communication and diagnostic data from multiple Electronic Control Units (ECU).
Applications of SAE J1939

Since its development, SAE J1939 has become the industry standard for trucks and buses. On top of these vehicle types, however, SAE J1939 has become a standard for a wide variety of commercial vehicles, including:

    Foresting machinery such as delimbers and skidders
    Mining vehicles like bulldozers and excavators
    Military vehicles like tanks and transport vehicles
    Agriculture equipment such as tractors and harvesters
    Construction equipment including cranes
    Emergency vehicles including ambulances and fire trucks
    Maritime vessels including military and commercial ships

While heavy-duty vehicles are the most well-known applications of SAE J1939, that isn’t the extent of this specification’s application. Many other industries use SAE J1939 as a whole or as a basis for their own standards. In fact, many military standards use SAE J1939 as a base or framework.
