The J1939 protocol was initially designed as a dedicated communication and diagnostics protocol for the complex networks of huge vehicles. It is commonly used in heavy-duty vehicles such as

Trucks, Tractors, Trailers, Agriculture vehicles, Material handling machines, Marine propulsion Aid and Rescue, and many other off-road vehicles.


Today, it is widely recognized by diesel engine manufacturers across the world.


J1939 provides diagnostic data such as:

- Vehicle engine speed

- temperature

- oil temperature

- exhaust emissions

- and other customizable options


It also:

              • Specifies how to handle multi-packet messages.

              • Enable communication across large complex networks.

              • Specifies how to convert data into human-readable information.

              • Defines diagnostics interface of its own.
