This Recommended Practice utilizes existing industry standards to identify a common physical interface and define the protocols necessary to retrieve records stored by light duty vehicle Event Data Recorders (EDRs). To accomplish this, the SAE J1962 Diagnostic Connector is designated as the primary physical interface for EDR Retrieval Tools. This Recommended Practice is intended to be used for the development of EDR Retrieval Tools. Retrieval tools are intended to interface with light duty vehicles and to produce EDR Record Reports with data element formats specified by SAE J1698-1. Limitations: This Recommend Practice specifies how EDR records should be imaged, translated, and reported by EDR Retrieval Tools. It does not specify how EDR records are recorded and stored by individual vehicles.
