Bosch: Invented for Life

Bosch Event Data Retrieval Tool Solutions

Bosch is a world leader in Event Data Recorder (EDR) information and imaging technology. Since 2000, Bosch Crash Data Retrieval (CDR) products have been trusted internationally by law enforcement, crash researchers, auto manufacturers and government agencies to access EDR information on a wide range of passenger cars, light trucks and SUVs.

Event Data Recorder

What is an Event Data Records (EDR)?

What is an Event Data Recorder (EDR)? An Event Data Recorder (EDR) is a device or function installed in a motor vehicle and its purpose is to record technical vehicle and occupant information for a brief period of time before, during and after a crash. The EDR function is typically located inside a vehicle’s airbag control module (ACM) and is capable of recording information (data elements) such as the vehicle’s indicated speed, brake pedal use, accelerator pedal input, steering wheel input, seatbelt status, airbag deployment performance information, crash severity and many more driver inputs and vehicle system status information.

Experts throughout the world use EDR readout tools for the retrieval of data from EDRs to assist with investigations of motor vehicle accidents. According to the US National Highway Traffic Safety Administration (NHTSA), EDR technology "...can make a major impact on highway safety, assisting in real-world data collection to better define the auto safety problem, aiding in law enforcement, and understanding the specific aspects of a crash."

United States

Beginning September 1, 2012, the United States Federal government through NHTSA put in force an EDR regulation called 49 CFR part 563. The US EDR regulation requires vehicle manufactures selling passenger car and light trucks equipped with and EDR into the US market are required to comply with the requirements defined therein. Most vehicle manufactures selling vehicles in the US equip their vehicles with a 49 CFR part 563 compliant EDR. Inclusive in the regulation, the US government states “a tool(s) shall be commercially available not later than 90 days after the first sale of the motor vehicle for purposes other than resale.”

South Korea

An EDR regulation with similar technical requirements as US 49 CFR part 563 was introduced in Korea starting December 15, 2015. Although there is no requirement for the availability of a commercial tool, vehicle manufacturers are required to respond to vehicle owner requests for retrieval of stored EDR data within an certain period of time. EDR readout tools such as the Bosch CDR Tool are available commercially in Korea, enabling vehicles manufacturers, police and other experts to retrieve data from crashed vehicles.


Starting January 1, 2021, all vehicles sold into the China market must be equipped with an EDR capable of recording a limited set of data elements which can be readout by a commercially available EDR readout tool. Beginning in 2023, China EDR regulations will be updated and require all new vehicles to comply with recording a common set of data elements using a specified protocol for reading and translating the EDR data using a common EDR readout tool.


According to the new General Safety Regulation announced in 2019 by the European Commission, beginning 2022, all cars, vans, trucks and buses sold in European Union countries will be required to be equipped with an EDR and corresponding readout tools must be commercially available.

Millions of passenger cars and light trucks on the road today, world-wide, are equipped with an EDR. In the United States and Canada alone, more than 200 million registered vehicles are equipped and approximately 98% of new vehicles sold in US and Canada today have an EDR.

EDR data is used today for vehicle crash research, accident investigation & reconstruction, product liability litigation, safety system field performance analysis and insurance claims. Today, there are a wide variety of users which include police, mechanical & forensic engineers, OEM engineers, universities, fleet personnel and insurance professionals. New applications for the use of EDR data collected from vehicles continue to surface as new industries rely on this technology.

The CDR product is easy to use when retrieving data directly from the vehicle but may require training and expertise for more complex and severe crashes and when analyzing the EDR data. There are many options available to users worldwide to receive CDR Tool training. Click here for information on available CDR Tool training organizations.

Specialty tools like the Bosch CDR Tool are required to retrieve EDR data from crashed vehicles. Data can be retrieved through the vehicle’s On-Board Diagnostic (OBD) connector but for severe crashes, where access to the OBD connector is not possible due to a damaged electrical system, the CDR tool can connect directly to the airbag control module (ACM) or electronic control unit (ECU) using one of many Bosch direct-to-module CDR cables. The Bosch CDR product line offers over 100 unique CDR cables, fitting more than 50 brands for connecting directly to a supported vehicle’s ACM or ECU.
