J1698/2_202307: Event Data Recorder - Retrieval Tool Protocol

Features

Issuing Committee: Event Data Recorder Committee

Scope

Content

This SAE 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 SAE 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 SAE 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.
This SAE Recommended Practice addresses EDR record retrieval (including imaging and translating) via the connection to the vehicle’s SAE J1962 connector or via direct connection to an electronic control unit (ECU) containing an EDR record. Direct connection to an ECU may require the use of specialized interface adapters.
