motor vehicles, has a number of
sophisticated computer systems that
monitor and control several aspects
of the vehicle performance. Your
vehicle uses onboard vehicle
computers to monitor emission
control components to optimize fuel
economy and to provide anti-lock
braking and to help the driver
control the vehicle in difficult driving
situations. These computers and
your vehicle's Data Recording
Module (DRM) also store
information about the performance
and status of certain systems in
your vehicle including the engine,
throttle, and braking systems.
