The focal point of the application is the networking of the power train. It’s often triggered by issues within the diesel engine's after-treatment system, particularly concerning the EGR and DPF. Many SPNs are combined into a PGN (Parameter Group Number) which gets a unique number and describes what is actually transmitted on CAN bus. each value to be transmitted) as an SPN (Suspect Parameter Number). SAE J1939 is a very easy protocol to use, but there is a lack of information about SAE J1939, due to the cost of the protocol document, available how Note: For more detailed information on the J1939 message format, please refer to the official SAE documentation or my book “A Comprehensible Guide to J1939.
