SAE J1939DBC

The SAE J1939 DBC file contains decoding rules for converting raw J1939 data to 'physical values' (Mph, %, etc.). This file lets you easily decode data from heavy duty vehicles (trucks, buses, tractors, etc.).This DBC file download includes:An SAE J1939 DBC file with ~1800+ PGNs and 12000+ SPNsThe J1939 Digital Annex Excel file (with additional PGNs/SPNs and description details)One legal license (1 user, 1 PC) matching the DA licenseDECODE J1939: Convert J1939 data in wide range of software/API tools1800+ PGNs: The extensive DBC contains 1800+ PGNs and 12000+ SPNsREVIEW FIRST: Use our CAN ID converter to check if your PGNs are coveredCROWD INPUT: Benefit from free corrections based on large user baseSAVE HOURS: Avoid manually constructing the DBC file from scratchWhat is a DBC file?A DBC file is a standardized method for storing the "rules" on how to interpret raw CAN bus data. In particular, it contains details on what 'signals' (e.g. RPM, Vehicle Speed, …) are contained within which 'messages' (i.e. CAN IDs).In the J1939 standard, messages are referred to as Parameter Group Numbers (PGN) and signals as Suspect Parameter Numbers (SPN).Further, a DBC file includes names, descriptions, positions and lengths of the signals - as well as how to offset & scale them.
