Abstract

Many airbag control modules (ACMs) write data to an electronic file in the event of a deployment or near-deployment of the frontal airbags. Retrieval of this data can be accomplished using dedicated hardware and software, and this process has come to be known as "Crash Data Retrieval" or CDR. CDR is performed as one component of the reconstruction of a motor vehicle incident. The retrieved data can only be understood and/or interpreted properly when viewed in conjunction with the physical evidence, setting, and environment used to reconstruct the incident. The only way to verify the data obtained via CDR is to compare it against the actual physical evidence and the results from conventional solution techniques, and this can only occur at a point in the reconstruction process when the conventional reconstruction efforts are completed or substantially so. When such an approach is used, CDR becomes another tool in the kit for accident reconstruction, and both compliments and expands the capabilities of conventional reconstruction techniques. The initial costs include the expense of the Vetronix CDR kit, ancillary tools, formal training, and overhead/administrative costs. With regards to CDR technology, formal training is not an option; it should be viewed as a mandatory part of the "commitment" required to institute this service. In addition to the Vetronix kit, additional equipment is required to access the ACM and conduct a download, and a list of equipment is presented. The initial costs and continuing costs to acquire the equipment and develop and maintain technical expertise are discussed. Most technical support is provided via an online forum, and the operation of this forum is discussed. Management options that may help reduce the cost of participating in CDR are discussed. Finally, miscellaneous practical issues based on the author’s experience are also discussed.
