Description

The J1939 comes from the international Society of Automotive Engineers (SAE) and works on the physical layer with CAN-high speed according to ISO11898. SAE J1939 defines five layers in the 7-layer OSI network model, and this includes the CAN 2.0b specification. The application focus is on the power trains and chassis of commercial vehicles.

All J1939 packets contain eight bytes of data and a standard header which contains an index called PGN (Parameter Group Number), which is embedded in the message’s 29-bit identifier. A PGN is unique numeric identifier that is associated with a specific parameter name. A PGN identifies a message’s function and associated data i.e a PGN defines the parameter value; a device is requesting or the parameter value that a device is sending.
