J1939 has become the accepted industry standard and the vehicle network technology of choice for heavy-duty machines. This cable enables serial data communication of microprocessor systems (also called Electronic Control Units-ECU) in any kind of heavy-duty vehicles. The exchanged data includes vehicle road speed, torque control message from the transmission to the engine, oil temperature, and many more. Heavy-duty materials and quality craftsmanship give the cable superior flexibility and durability.
