SAE J2602-2_202110

This document covers the tests to be performed on all SAE J2602-1 (2021 revision) devices. Tests described in this document will ensure a minimum standard level of performance to which all compatible electronic control units (ECUs) and media shall be designed. This will assure full serial data communication among all connected devices regardless of supplier.

The goal of SAE J2602-2 is to improve the interoperability and interchangeability of LIN devices within a network by verifying the devices pass a minimum set of tests.

To allow for easy cross-reference, this document is arranged such that the conformance test for a given section in SAE J2602-1 (2021 revision) is in the same section in SAE J2602-2.

This document is to be referenced by the particular vehicle original equipment manufacturer (OEM) component technical specification that describes any given ECU in which the LIN data link controller and physical layer interface is located. Primarily, the performance of the physical layer is specified in this document. ECU environmental and other requirements, when provided in the component technical specification, shall supersede the requirements of this document.

The intended audience includes, but is not limited to, ECU suppliers, LIN controller suppliers, LIN transceiver suppliers, component release engineers, and vehicle system engineers.
