ISO 15765-4 is the fourth part of multiple series that specifies requirements for CAN-based communication systems between the in-vehicle network and the diagnostic link connector of the vehicle. This document specifies the requirements to enable the in-vehicle CAN-based communication systems to establish, maintain, and terminate communication with the devices connected to the diagnostic link connector.
NOTE-
ISO 15765-4 does not specify any requirements related to the in-vehicle CAN network architecture.
ISO 15765-4 on diagnostic communication over Controller Area Network (DoCAN) is useful for:
ISO 15765-4 has been established in order to define common requirements for vehicle diagnostic systems implemented on a controller area network (CAN) communication link. It is intended for diagnostic systems. It also meets requirements from other CAN-based systems needing a network layer protocol. It is very useful for the diagnostic communication over Controller Area Network (DoCAN).
ISO 15765-4 provides the application of vehicle that is useful for CAN-based communication systems between the in-vehicle network and application layer to diagnostic link connector of the vehicle.
BS ISO 15765-4:2021 supersedes BS ISO 157654:2016, which is withdrawn.
This fourth edition replaces the third edition (ISO 157654:2016), which has been technically revised.
