DESCRIPTION AND OPERATION
TRIP COMPUTER
A mini trip computer is available on this model to
provide several electronic functions and features. The
trip computer contains a central processing unit and
interfaces with other modules in the vehicle on the
Chrysler Collision Detection (CCD) data bus network.
The CCD data bus network allows the sharing of
sensor information. This helps to reduce wire har-
ness complexity, reduce internal controller hardware,
and reduce component sensor current loads. At the
same time, this system provides increased reliability,
enhanced diagnostics, and allows the addition of
many new feature capabilities.
