Function and purpose of J1939 to OBD2 cable

J1939 to OBD2 cable is a commonly used vehicle diagnostic tool. What are its specific functions and uses? Today, the editor will introduce it to everyone.

Protocol conversion: J1939 is a communication protocol designed specifically for heavy-duty vehicles, while OBD2 is a universal diagnostic interface standard for automobiles. The J1939 to OBD2 cable converts J1939 protocol data into a format recognizable by the OBD2 protocol through a built-in protocol conversion module, achieving seamless integration between the two protocols.

Fault diagnosis: By connecting the J1939 to OBD2 cable, maintenance personnel can use standard OBD2 diagnostic tools to read the fault codes, real-time data streams, and other information of heavy vehicles, quickly locate the fault point, and improve maintenance efficiency.

Data monitoring: For scenarios such as fleet management and remote vehicle monitoring, J1939 to OBD2 cables can transmit real-time vehicle operation data, such as vehicle speed, RPM, fuel consumption, etc., providing strong support for vehicle management.
