Single Wire CAN Network for Vehicle Applications
Foreword—The objective of this SAE Standard is to define a level of standardization in the implementation of low
speed vehicle serial data network communications using the Controller Area Network (CAN) protocol. This low
speed implementation of CAN is intended to provide a lower cost complement to the SAE J2284 High Speed CAN
standard.
The goal of this document is to define a serial data physical layer, data link layer and media design criteria to be
installed in various automotive Electronic Control Units (ECU). This document will allow ECU and tool
manufacturers to satisfy the needs of multiple end users with minimum modifications to the basic design. This
document will benefit vehicle Original Equipment Manufacturers by achieving lower ECU costs due to higher
industry volumes of the basic design.
