Definition
The Bosch Crash Data Retrieval tool: the industry-standard hardware-software system used to interface with automotive EDR modules via the OBD diagnostic port or direct module wiring, extract the stored data, and produce a standardised report file.

Common questions
What vehicles does the CDR tool support?+
Coverage is make-and-model specific and updated in periodic software releases; not every vehicle's EDR module is supported, and some require direct module removal rather than OBD-II access.
Does the CDR tool interpret the crash for the investigator?+
No, it only extracts and formats the stored module data such as delta-V, speed and seatbelt status. Interpreting that data into a crash narrative is a separate reconstruction step done by a trained analyst.
