Specification for J1939 over CAN FD published

On March 22, 2021, SAE published the SAE J1939-22 document. This document is the latest addition to the J1939 set of standards for electronic controls within heavy duty vehicles, specifically incorporating the requirements of CAN FD.

Over a span of four years, a team of talented volunteer engineers, led by Task Force Chairman Andy Vlietstra of Woodward, created a ground up specification packaging J1939 data to take advantage of the increased capabilities of CAN FD.

Bryan Hennessy, Kvaser Field Applications Engineer notes: “This is a specification that will improve data communications within heavy duty vehicles throughout the world for decades to come.”

The J1939 standards are available for purchase from SAE directly at this link.
