Foreword
This series of SAE Recommended Practices have been developed by the Truck and Bus Control and
Communications Network Subcommittee of the Truck and Bus Electrical Committee. The objectives of
the subcommittee are to develop information reports, recommended practices, and standards concerned
with the requirements design and usage of devices which transmit electronic signals and control
information among vehicle components. The usage of these documents is not limited to truck and bus
applications. Other applications may be accommodated with immediate support being provided for
construction and agricultural equipment and stationary power systems.
These SAE Recommended Practices are intended as a guide toward standard practice and are subject
to change to keep pace with experience and technical advances.
