Custom Heavy Vehicle Diagnostic Cables

Custom Heavy Vehicle Diagnostic Cables 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. Our OBD Diagnostics 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. 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 mon…
