Everything You Want to Know About HEDR
Get a closer look at the tool designed for effortless and reliable EDR extraction.
Why can one cable support multiple models?
HEDR uses a universal adaptive interface with multi-protocol recognition.
It automatically identifies vehicle communication protocols and connects directly to various ACM modules—no repeated cable changes, no pin-mapping uncertainty, and no unnecessary complexity.
Does HEDR offer free software updates?
We regularly releases software updates to expand the range of supported vehicle models and improve overall functionality. Currently, all HEDR software updates are provided free of charge to users.
Which Tesla models does HEDR support？
The latest standard HEDR configuration includes three Tesla-specific EDR retrieval cables, enabling direct data extraction from all major Tesla models (including the Model 3, Model S, Model X and Model Y) without the need for additional adapters.
How is the authenticity of HEDR-read data ensured?
HEDR is designed to read and copy the data stored in the vehicle’s EDR module only; it does not alter, overwrite or delete the original crash data. If you follow the proper procedure, HEDR ensures that the same raw EDR data is extracted every time, functioning like mirroring a digital file rather than editing it.
How does HEDR ensure the integrity and accuracy of the retrieved EDR data？
HEDR reads the EDR data three times and cross-verifies the results to confirm complete consistency across all readings. The report includes the raw hexadecimal data, enabling the results to be re-decoded and verified independently.
How does HEDR ensure data security?
All data is stored and encrypted securely on site to prevent tampering or leakage, and to comply with legal and insurance evidence requirements.
