Event Data Recorders are identified by a number of names and acronyms (EDR, RCM, SCM, PCM, Black Box, Air bag Module Etc.) They functions within one or more vehicle electronic modules that capture the vehicle and restraint information in the event of a crash in which air bags may or may not deploy. In General Motors vehicles, the EDR function is typically housed in a control module, such as the sensing and diagnostic module, the engine control module or the stability control or 4-wheel steering modules. These modules are located in various places in the vehicle, such as under a front seat, in the center console or under the dash.
What is the difference between an EDR and a "black box"?

A "black box" typically refers to a flight data recorder (FDR) used in aircraft. The FDR records extensive crash and in-flight data and is intended to be used to reconstruct the cause of a crash. A vehicle EDR records limited crash data and is used to understand vehicle system operations.
