Vehicle Crash Data Retrieval - Crash Data Group

Reference: 2006 Chrysler 300 Note: #3 How can I identify which ACM that cant be read by the CDR ? Will an attempted read destroy any of the information on those ACM's which cannot be read ? (2010-03-05)

When you attempt a download of an unsupported module, it will return a message in the File Information block tht there was "data not retrievable." Attempting to retrieve data but that attempt being unsuccesful does nothing to what, if anything, is in the module.

Will the most current version of CDR extract vechile speed and throttle position on a 2005 Dodge Dakota? I have been told events are not retrievable by the CDR tool (2010-03-05)

The 05 Dakota is not currently supported by the CDR System.

I took a box out of a car and the box was under water. How long should I dry out the box before an attempted download? The box seems to be sealed well and I can't hear any water in it. I have it in a room with a dehumitifier and the huimity stays below 50%. Thanks. (2010-03-05)

Refer to the presentation from the CDR User's Summit in houston in January by Sean Haight for details but there is no specific time, "dry is dry." Once it's dry inside and you initiate a download and it is successful, it was "dry enough." If it's still "too wet" it simply won't communicate.

I conducted a download via DLC port on a 2001 Cadi Deville. It was T-boned on the passenger side and the frt pass side airbag deployed. Under CDR file info it states: Event(s) recorded: Non-deployment. What would cause this? I thought maybe a power failure however with this crash I know that could not have been the case. All the other data in the download can be varified w/ my reconstruction, however I can not explaine the Non-Deployment. Thanks for your help (2010-01-19)

A non-deoployment file created as a function of a side impact is not uncommon. This is NOT related to a power interruption. The SDM in that vehicle offers information about the frontal bags not side bags so a side bag deployment can occur but the frontal "event" recognized could easily be a non-deployment.

Hello - When I went to the CDR course last year, I remember a PowerPoint slide that read something like "The CDR system is not a substitute for a complete auto accident re-construction and should be backed up by evidence.....etc". I looked for that slide, but haven't had any luck. Do you know where I can find that? (2010-01-07)

Not exactly. The slide reads: "The CDR data analysis Analysis takes into account the available information toward an analysis including� Information about the humans, the vehicles and the environment, Will normally require at least an analysis of the vehicle dynamics and Many times an evaluation of the physical evidence supporting the analysis of those dynamics It may require a detailed mechanical inspection" The course material then goes on to talk about "A 'situationally complete' crash analysis may be based on�" What's a "complete reconstuction?" Wouldn't each crash be different, present different available information to work with? lacking a clear definition of a "complete" reconstruction, really, we have to take data recovered using the CD system as part of the information we have to work with in light of the crash facts and information available.

I have recently recieved a netbook laptop computer for use in accident investigation. Without a disc drive, how do I download and license the new software on the netbook, an HP mini using Window 7 starter? Using flash drive, I transferred software info from original laptop to netbook, but I get Error Number 339 and it says Component 'VSPRINT7.OCX' or one of it's dependencies not correctly registered: a file is missing or invalid (2009-12-16)

It sounds like you just copied the files from one computer to another rather than running an installation. If your license for the software allows for multiple installations, you should copy the contents of the installation CD to the thumb drive and install from that drive or from a folder where you copied those contents to the netbook. Missing or improperly registered files are normally a function of incomplete or improper installations.

Will an airbag deploy if the ignition is off. I'm working a fraud case where the vehicle is most probably parked and the collision is staged. Heavy side impact but the side air bag does not deploy. (2009-12-16)

On those vehicles accessible by thge CDR system, they key has to be ON for the airbag control module to be able to deploy an airbag. Some older Fords would deploy bags with they key off, but not anything in the range of vehicles which are CDR accessible.

I'd like to know the answer to the following questions for a news story on EDRs. I was wondering if it is standard practice to try to retrieve event data recorders (EDRs) from vehicles equipped with them after fatal crashes, as far as most police departments go? What kinds of situations warrant the inspection of information from an EDR? Is there some kind of special equipment that is needed to remove the EDR or EDRs from a vehicle? How long does it usually take to process this kind of data once a request is made? What is used to process or remove the data from an EDR (specialized computer program or equipment)? How accurate is data from an EDR? (2009-11-06)

Q: I was wondering if it is standard practice to try to retrieve event data recorders (EDRs) from vehicles equipped with them after fatal crashes, as far as most police departments go? A: There is no simple answer here, "most police departments" is too broad and there are too many varying laws, policies and departmental processes/procedures to recount them all here. Q: What kinds of situations warrant the inspection of information from an EDR? A: Crashes involving passenger cars, light trucks and SUVs. Q: Is there some kind of special equipment that is needed to remove the EDR or EDRs from a vehicle? A: There is no such thing as a stand-alone "EDR" installed by an OE in the context of the information available on this site and relating to the Bosch Crash Data Retrieval System. One would not "remove" an EDR. One may remove the safety device control device in which there may be a conditionally functional EDR subcomponent or subsystem but then that would render the safety device (i.e.: air bag) inoperable. Q: How long does it usually take to process this kind of data once a request is made? A: Depending on the complexity of the crash, the process includes imaging the data from the relevant control module, then comparing it to a crash analysis of varying complexity and detail which, by itself, can take weeks. Q: What is used to process or remove the data from an EDR (specialized computer program or equipment)? A: Review the remainder of this web site where the Bosch Crash Data Retrieval System is sold and you will find the various components of the Bosch CDR system which, together with pretty much any laptop or desktop computer, will run the CD software. Q: How accurate is data from an EDR? A: First, in the context of OE installed devices and those which are accessible using the Bosch CDR system, an EDR subcomponent is not a stand alone device; it is a storage process for the data generated largely in other components or sensors and then relayed to the relevant control unit which then stores - when and if the EDR functionality is engaged - that data for later retrieval. So, asking "is data from an EDR accurate" is like asking "if I save something I typed in Word on my computer to my hard drive and then to a thumb drive, would the thumb drive accurately save the data?" Experientially, we can each answer that question. The question you probably mean to ask is: "how accurate is the underlying data which is ultimately stored by the EDR functionality?" The answer to that is "for the most part, depending on how one understands the difference between 'accurate' and 'precise' and then within a larger appreciation for what is and is not stored, the data that can be recovered is generally very accurate."

Does a 204 Toyota Camry store crash data, and is it retreivable? Thanks, Joe (2009-10-27)

Toyota vehicles are not accessible using the Boach CDR systema t this time.

I would like to know if you have any accesability to the european models,such as BMW AUDI VW MERCEDES OPEL Etc.THks (2009-09-15)

At the same place where you found this FAQ, you will find this link: http://www.cdr-system.com/resources/coverage.html which is the current "Crash Data Retrieval Vehicle Coverage List." It indicates that the Bosch system covers Ford, GM and Chrysler vehicles. While there is, for example, Saab coverage under the heading "GM," lines like Opel and, at this point, Holden, are not supported.
