The Bosch Crash Data Retrieval System was used to conduct this analysis. “CDR” is an acronym for the Crash Data Retrieval. This system consists of a kit containing software, cables, and an interface module designed (and periodically upgraded) specifically to create an image of the data and translate the information stored in the Airbag Control Module (ACM). The kit is used in conjunction with a computer. The system will produce a report for each module imaged and a copy of each will be contained in the appendix of this report. “Algorithm Enable” (AE) is also commonly used. AE occurs when there is a force (impulse) detected by the module that is significant enough to cause the module to begin analysis of the force and to determine whether to deploy the airbag. Depending on the amount and duration of the force, the module may deploy the airbag. The time at which AE occurs is used as a reference (or zero) point for most time measurements. However, AE, is not necessarily the precise instant of the crash. Sensing Diagnostic Module (SDM) is manufacturer specific for General Motors and is the same thing as …show more content…
