Most early GM air bag SDM modules can contain 5-15 pages of crash data information. Many 2006 and newer GM vehicles will have 30-40 pages of crash data information. A recent download of a 2010 Chevrolet Camaro produced 72 pages of crash data.

Why was I not told my GM car had a 'black box' when I bought it?
Most GM dealers are not aware of the recording ability of the air bag SDM. The fact that the air bag module is recording data is explained in the vehicles owners manual.
Example: 2001 Cadillac owners manual statement.
"Your vehicle is equipped with an electronic frontal sensor, which helps the sensing system distinguish between a moderate frontal impact and a more severe frontal impact. Your vehicle is also equipped with a crash sensing and diagnostic module, which records information about the frontal air bag system. The module records information about the readiness of the system, when the system commands air bag inflation and driver's safety belt useage at deployment or near-deployment crash. The module also records speed, engine rpm, brake and throttle data."
Who owns the air bag SDM /EDR 'black box' module crash data?
Basically, the owner of the vehicle owns the crash data. Example: If a insurance company pays off your wrecked vehicle, they now own the air bag SDM crash data. Then, if the insurance company sells the vehicle to a salvage yard, then the salvage yard owns the air bag crash data.
The black box in your car may get possible legislation..
New legislation is up for debate in North Dakota that would require car buyers to be told if their new car or truck is equipped with a black box that records accident information. The bill also would only allow black-box-gathered information in court unless there is a court order to do so. Other states are also considering black box regulation like Connecticut, New Jersey, New York and Virginia.
