Purpose 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. Differences from ISO Document The ISO 15031-3 document is intended to satisfy the 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. U.S. OBD regulations specify a connector location that may be more restrictive than specified in this document or the ISO 15031-3 document. b. 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.
