Crash Data Retrieval
In addition to our automotive expertise, we are pleased to offer a state-of-the-art Crash Data Retrieval System or CDR.
With this system, we are able to obtain vital information that occurred prior to and after an impact on most General
Motors, Chrysler and Ford vehicles manufactured after 2000.
The vehicle's computer system collects vehicle data that occurred within 5 seconds prior to impact. The CDR records the
following information, in one-second increments, for the five seconds prior to a crash or near crash occurrences. This
information includes:
- The brake status – at what point the brake pedal was depressed
- Vehicle speed – the speed of the vehicle in miles per hour
- Engine speed – engine RPM throughout the recorded event
- Throttle percentage – this identifies the placement of the throttle pedal
- Status of the driver's seat belt switch at impact – buckled or unbuckled;
- Time between the impact and air bag deployment (in milliseconds)
- Status of the SIR (airbags) warning lamp when impact occurred
- Ignition cycles at the time of the incident and the inspection.
The information obtained from the CDR is very useful in determining the brake pedal and throttle application data in
both alleged brake failure cases and unwanted acceleration claims.
