VEHICLE DATA COLLECTION AND EVENT DATA RECORDERS
Your Hyundai vehicle is equipped with many high technology, electronically controlled systems that help to ensure
your vehicle operates properly and provides the performance that you expect. These systems utilize computers
to monitor the operation of various systems and components and help to control their operation. These
computerized system operations are wide-ranging and involve components to reduce emissions, to continuously
evaluate the readiness of the airbag and seat belt pretensioner systems, to determine when the airbag and seat
belt pre-tensioner systems should be deployed and then to activate the deployment, and if equipped, to operate
anti-lock braking, traction control and electrical stability control to assist the driver to control the vehicle in difficult
driving situations. These systems electronically store information that is useful to service technicians when they
need to diagnose and repair these systems. Additional information is stored only when a crash occurs that results
in the deployment of the airbags or seat belt pre-tensioners. This type of data storage is done by devices called
event data recorders(EDR).
After a crash event, the airbag and seat belt pre-tensioner computer system, known as the Supplemental
Restraint System Control Module (SRSCM) or Airbag Control Unit (ACU), may record some information about
the condition of the vehicle and how it was being operated. This information consists of data related to seat belt
usage and if there was diagnostic information in the airbag or seat belt systems at the time that a crash occurred,
and if the ACU sensed that a crash of sufficient severity occurred to require seat belt pre-tensioner or airbag
deployment.
To retrieve this information, special equipment is needed and access to the vehicle or the device that stores the
data is required. Hyundai will not access information about a crash event or share it with others except:
o in response to an official request of police or similar government office, or
o with the consent of the vehicle owner or, if the vehicle is leased, with the consent of the lessee, or
o as part of Hyundai’s defense of litigation, or
o as required by law.
