Doesn’t seem the 2015 Elantra owner’s manual is still online but here is only one of the articles I found. If you Google, there are a number confirming the Elantra has a “black box.”
Yes, the 2015 Hyundai Elantra is equipped with an
Event Data Recorder (EDR).EDRs, also known as black boxes in cars, are memory chips that record data during crashes.
Where is the EDR located?
The EDR memory chip is typically stored within the car's
Airbag Control Module (ACM) or
Restraint Control Module.
What kind of data does the EDR record?
The EDR records various data points in the moments leading up to and during a crash, including: Speed, Engine throttle, Whether seat belts were used, and Whether brakes were applied.
How can the data be accessed?
The data can be accessed by:
- Connecting a diagnostic tool to the vehicle's diagnostic port.
- Removing the ACM module and accessing the memory chip.
Why is the EDR important?
The EDR can provide valuable information about a car accident, helping to:Establish the key facts of the accident, Reconstruct the accident scene, and Aid in investigations.
Important Note: EDRs do not record data continuously; they only record data when a crash event is detected.
