Vehicles have evolved into very sophisticated machines which utilize numerous computerized systems to ensure the vehicle operates correctly. Modern vehicles are equipped with multiple computer systems which monitor and control various systems such as airbags and passenger restraint systems, traction and stability control systems, anti-lock brake systems, and engine control systems. Federal regulation CFR 49 part 563 mandates that every passenger car and truck manufactured after September 1, 2012 (with some limited exceptions), make pre-crash data accessible using commercially available equipment. However, for vehicles manufactured prior to September 1, 2012, only select manufactures have elected to make pre-crash data available for download. Please reach out to Veritech for information on supported vehicles with model years prior to 2012, to see if they have data recording capabilities.

What is a Vehicle Black Box?
Most modern vehicles are equipped with a black box, commonly referred to as an Event Data Recorder (EDR), Airbag Control Module (ACM), or Powertrain Control Module (PCM). These devices record critical vehicle information before, during, and after a crash. Among these, the ACM is most frequently used to capture digital crash data that can be retrieved to understand the specifics of an accident.
The ACM constantly monitors a vehicle’s system parameters to determine whether supplemental restraint systems (SRS), such as airbags, should deploy during a crash or rollover. In the event of an accident, the ACM captures and stores this data, providing a valuable resource for accident reconstruction, crash analysis, and legal investigations.
Key Data Stored in Vehicle Black Boxes
The ACM and other vehicle black boxes typically record information including:
-
Vehicle speed at the time of the crash
-
Brake application and throttle input
-
Steering inputs
-
Seatbelt usage
-
Impact-related delta-V (severity of the collision)

Notably, this data may be captured even if the airbags do not deploy, making it valuable for analyzing lower-severity collisions. Black boxes are found in a variety of vehicles, including passenger cars, commercial trucks, semi-tractors, trains, aircraft, motorcycles, and even some off-road vehicles.
Commercial Vehicle and Heavy Truck Event Data Recorders
Many commercial vehicles and heavy trucks include engine control modules (ECM) capable of recording pre-crash information. ECMs store vehicle speed, braking, and other operational data, although they were primarily designed for engine management rather than accident reconstruction.

Newer commercial vehicles often contain auxiliary modules, such as brake control modules, which capture additional event-related data. Proper extraction and interpretation of ECM and auxiliary module data requires specialized knowledge, as these systems are complex and data may not always directly correspond to crash events.
Limitations of Black Box and ECM Data
While vehicle black boxes and ECMs provide valuable insights, the data has limitations:
-
Data accuracy depends on system design and vehicle model. Some information may include errors that can affect reliability.
-
Improper interpretation by untrained users can lead to incorrect conclusions or inconsistencies with physical evidence.
-
Corroboration with crash scene evidence is essential to validate data and ensure accurate reconstruction. For example, vehicle crush energy must be consistent with the information extracted from the vehicle's black box.
At Veritech, our engineers are trained to download, interpret, and validate data from almost all makes and models of passenger vehicles, commercial trucks, and heavy equipment. We ensure that black box and ECM data are consistent with physical evidence, providing reliable information for accident reconstruction, insurance investigations, and litigation.
Why Veritech is a Trusted Resource for Black Box Analysis
Our in-house capabilities allow us to retrieve and analyze data from a wide range of airbag control modules, event data recorders, and engine control modules. Veritech engineers are experienced in interpreting the complex datasets contained within these devices, providing critical insights into the sequence of events leading to a crash, vehicle performance, and operator actions.
If you need expert analysis of your vehicle’s black box or ECM data, the first step is to contact Veritech. We can assess your vehicle’s make, model, and crash circumstances to determine what data may be available and how it can support your accident reconstruction or legal case.
