Diagnostic Connector Equivalent to ISO/DIS 15031-3:December 14, 2001

This document supersedes SAE J1962 FEB1998, 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. Differences from ISO Document. The ISO 15031-3 document is intended to satisfy the requirements of OBD requirements in countries other than the U.S., and includes functionality not required or not allowed in the U.S. Notable exceptions are: a. Proposed U.S. OBD regulations specify a connector location that is more restrictive than specified in this document. b. Proposed U.S. OBD regulations do not allow greater than 20 V at the SAE J1962 connector. Only the Type A connector as defined in this document is allowable. Differences between the documents are highlighted in the technical requirements sections of this document. Deleted text is highlighted with strikethrough and new text is highlighted with bold italic. NOTE - To maintain equivalency of the documents, a comma is used as a decimal marker for numeric values in this document.
