Decoding the OBD2 Standard in Freightliner Trucks

Freightliner trucks, being commercial vehicles, adhere to different diagnostic standards than passenger cars. While the term “OBD2” is frequently used, it’s not entirely accurate for these heavy-duty vehicles. Freightliner trucks typically use a variant of OBD, often referred to as J1939, which is specifically designed for heavy-duty vehicles. This standard allows for more comprehensive diagnostics than OBD2, encompassing not only the engine but also other critical systems like brakes, transmission, and emissions.
