J1939 DBC File – Decode Heavy Duty Data [PGN & SPN Database]
The SAE J1939 DBC file contains decoding rules for converting raw J1939 data to ‘physical values’ (km/h, %, …). This lets you easily decode data from heavy duty vehicles (trucks, buses, tractors, …).
DBC is a CAN database format used in most automotive tools – incl. our CAN software/APIs.
The download includes a legal J1939 DBC & license, based on the J1939 Digital Annex Excel file (also included). We offer this in collaboration with SAE. For company-wide quotes, contact us.
The DBC revision is 2024-12.
Tip: Contact us for a free ‘sample conversion’ of a CLX000/CANedge log file.
