Quest Engineering performs Heavy Vehicle Event Data Recorder (HVEDR) retrieval and analysis for commercial trucks, buses, and other heavy transport assets. Commercial electronic control modules (ECMs) capture critical data during a triggering event, providing objective evidence for litigation and accident reconstruction.

​

Data We Retrieve & Analyze:

• Speed Metrics: Vehicle speed, engine speed (RPM), and change in velocity.

• Driver Inputs: Brake application status, throttle position, and steering data.

• System Diagnostics: Diagnostic Trouble Codes (DTCs) and fault history.

• Multimedia: Onboard camera video footage and forward-facing photos.
   

Electronic Sources We Target:

• Engine Control Modules (ECMs): Core engine data and event triggers.

• Airbrake System Modules: ABS, traction control, and electronic stability logs.

• GPS & Fleet Tracking: Telematics hardware, route history, and fleet tracking equipment.
   

Comprehensive Trucking Accident Investigation:

HVEDR data is most powerful when contextualized. Quest Engineering integrates electronic findings with:

• Physical scene documentation and roadway geometry

• Hands-on vehicle inspections and mechanical damage analysis

• Electronic Logging Device (ELD) hours-of-service records

• Fleet maintenance and repair history
   

Who We Serve:

We provide motor carriers, trucking companies, insurers, attorneys, manufacturers, and claims professionals with objective, defensible analysis to evaluate driver actions, vehicle performance, event timing, and collision dynamics.
