Vehicle Data Collection And Event Data Recorders - Chevrolet Kodiak 2006 Owner's Manual

Canadian Roadside Assistance
In Canada, Medium Duty trucks are not eligible
for Roadside Assistance services. However,
owners/operators who contact Roadside Assistance
by calling 1-800-268-6800 may have a tow arranged
for them at the owner/operator expense.
If a Medium Duty truck is towed to the nearest General
Motors dealership and the towing was necessary
due to failure of a warranted part, the dealer will accept
the towing charges and submit them as part of the
warranty claim.
Vehicle Data Collection and
Event Data Recorders
Your vehicle, like other modern motor vehicles, has a
number of sophisticated computer systems that
monitor and control several aspects of the vehicle's
performance. Your vehicle uses on-board vehicle
computers to monitor emission control components to
optimize fuel economy, to monitor conditions for
airbag deployment and, if so equipped, to provide
anti-lock braking and to help the driver control the
vehicle in difficult driving situations.

Some information may be stored during regular
operations to facilitate repair of detected malfunctions;
other information is stored only in a crash event by
computer systems, such as those commonly called
event data recorders (EDR).
In a crash event, computer systems, such as the Airbag
Sensing and Diagnostic Module (SDM) in your vehicle
may record information about the condition of the vehicle
and how it was operated, such as data related to
engine speed, brake application, throttle position, vehicle
speed, safety belt usage, airbag readiness, airbag
performance, and the severity of a collision. This
information has been used to improve vehicle crash
performance and may be used to improve crash
performance of future vehicles and driving safety. Unlike
the data recorders on many airplanes, these on-board
systems do not record sounds, such as conversation of
vehicle occupants.
