Core Advantages
Key Features
TRACETECH™ HEDR is designed to make crash data retrieval more practical, structured and reliable for professional investigation workflows.
Practical Field Workflow
Designed for real investigation scenarios where vehicle condition, access method and case requirements may vary.
Guided Operation
Clear software guidance helps users follow vehicle selection, connection, reading and report generation steps.
Case-Oriented Data Handling
Retrieved data can be organized for accident reconstruction, insurance review, forensic analysis and official documentation.
Controlled Local Storage
Case data is stored locally, supporting controlled data handling for sensitive investigation environments.
Consistency Check Workflow
Repeated reading and data verification help users review result consistency before generating a final report.
Distributor & User Support
Remote technical support is available for compatibility checks, operation guidance and troubleshooting.
OBD Plug-and-Read Data Access
Fast Access Through the Vehicle OBD Port
For compatible vehicles, TRACETECH™ HEDR allows crash data retrieval through the vehicle OBD port. This plug-and-read workflow helps reduce preparation time and makes the reading process more efficient for investigators and technicians.
OBD access is suitable for vehicles where the diagnostic port remains available and the EDR data can be retrieved through supported communication protocols.
Integrated ACM Module Coverage
Direct ACM Connection for Damaged Vehicles
When the vehicle is heavily damaged or OBD access is not available, TRACETECH™ HEDR supports direct connection to compatible ACM modules. This provides an alternative retrieval method for real investigation scenarios.
Graphical wiring guidance helps reduce connection uncertainty during ACM data extraction and supports a more practical workflow for field investigation and forensic analysis.
