Event data recorders
The vehicle has a number of
sophisticated systems that monitor
and control several vehicle data.
Some data may be stored during
regular operation to facilitate repair
of detected malfunctions, other data
is stored only in a crash or near
crash event by systems commonly
called event data recorders (EDR).
The systems may record data about
the condition of the vehicle and how
it was operated.
To read this data special equipment
and access to the vehicle is required.
This will take place when the vehicle
is serviced in a repairer. Some data
is electronically fed into GM global
diagnostic systems.
