This Recommended Practice is intended to define a common method for determining how to extract Event Data from a motor vehicle, including the Event Data Set needed to output the Event Record of data elements defined in SAE J 1698. It is intended for use by those developing tools for the purpose of Event Data Set extraction.This Recommended Practices aims to utilize existing industry standards to define a common physical interface and the protocols necessary to Event Data Set extraction. To accomplish this, the SAE J 1962 Diagnostics Connector has been designed the primary physical interface and associated industry standard diagnostic protocols have been designated for communications.
