SAE J3248_202402

This document focuses on the latest in-force regulations. However, in addition to latest information, the report may include historical information. As regulations are superseded, the previous entry will remain to help understand the change in requirements over time. The initial focus of the document includes light-, medium-, and heavy-duty on-road vehicles with all propulsion systems. The document will include information from the United States and Canada, with later publications expanding to other regions. Forecasts for future regulations will not be included in the spreadsheet but be kept in a separate document. The document may be expanded to other types of applications/vehicles as information becomes available. This report is being published to document the latest and most accurate information available on On-Board Diagnostic (OBD) regulations. This report does not develop new regulations, rather it collects the regulations. The information is then organized into a digital annex (spreadsheet format) for ease of use and searchability. This document is not in response to direction by any government agency or regulator, rather it is an independent collection of existing regulations by Worldwide OBD experts.
