This document supersedes SAE J1962 200204, and is technically equivalent to ISO/DIS 15031-3: December 14, 2001.
This document is intended to satisfy the requirements of an OBD connector as required by U.S. On-Board Diagnostic (OBD) regulations. The diagnostic connection specified in this document consists of two mating connectors, the vehicle connector and the external test equipment connector.
This document specifies: a. The functional requirements for the vehicle connector. These functional requirements are separated into four principal areas: connector location/access, connector design, connector contact allocation, and electrical requirements for connector and related electrical circuits, b. The functional requirements for the external test equipment connector. These functional requirements are separated into three principal areas: connector design, connector contact allocation, and electrical requirements for connector and related electrical circuits.
This document is being revised by the SAE J1962 Task Force in response to a request from the California Air Resources Board (CARB) to SAE for clarification regarding the access area to the vehicle diagnostic connector that is intended to provide proper clearance for the mating of the scan tool connector to the vehicle. As a result of the CARB request, the SAE Vehicle E/E System Diagnostic Standards Committee approved the task of reviewing and revising for clarification this SAE J1962 Specification.
