Page Count: 10
scope:

This document defines a physical layer having a high bandwidth capacity utilizing the Flexible Data Rate Frame Format as defined in ISO 11898-1:2015. CAN controllers which support this format and compatible high speed transceivers are required for use on SAE J1939-17 networks.

This SAE Recommended Practice is intended for light- and heavy-duty vehicles on- or off-road as well as appropriate stationary applications which use vehicle derived components (e.g., generator sets). Vehicles of interest include but are not limited to: on- and off-highway trucks and their trailers; construction equipment; and agricultural equipment and implements.

Purpose

Implementing a robust CAN network involves many tradeoffs affecting both the network layout and ECU design. This document presents a standard by which ECUs, tools, and vehicle networks from different sources may be compatible. The document is intended to stand alone, yet borrows from the many existing standards and papers for its methodology.
