SDM is the "black box":
Air bag deployment 'black box' SDM / EDR crash data recovery for 1994 and newer GM and Saturn vehicles using the Vetronix crash data retrieval tool.

Logan Diagnostic offers air bag deployment crash data retrieval via the air bag SDM module for General Motors (GM) and Saturn vehicles. This can only be done using the Vetronix crash data retrieval tool (CDR) and a PC. We can offer a report on the stored crash data in the air bag SDM module recorder (aka the 'black box', EDR or event data recorder). The air bag SDM recorder can offer extremely important vehicle data in the final 5 seconds leading up to an accident event.

Vehicle speed (in five one-second intervals preceding impact)
Engine speed (in five one-second intervals preceding impact)
Brake status (in five one-second intervals preceding impact)
Throttle position (in five one-second intervals preceding impact)
Driver's seat belt state (On/Off)
Passenger's airbag enabled or disabled state (On/Off)
Airbag Warning Lamp status (On/Off)
Time from vehicle impact to airbag deployment
Maximum Delta-V ( DV ) for near-deployment event

How does it work? The air bag SDM module (GM) is removed from the wrecked vehicle and shipped to Logan Diagnostic. We will then power up the air bag SDM module and download the recorded crash data report from the module using the Vetronix CDR. Our report services include:
High quality printed and bound report of the stored air bag crash data.
CD-ROM of the stored air bag crash data in PDF format.
Return overnight shipping of the airbag deployment crash data report, CD-ROM, and the original SDM airbag module.
The PDF crash data can also be sent by email the same day.
Our service is only available for 1994 and newer GM and Saturn vehicles.
Please feel free to contact us if you require more air bag information or if you need the crash data downloaded from a GM air bag SDM /EDR.
