GENERAL INFORMATION
INTRODUCTION
An overhead console featuring a mini trip com-
puter, an electronic compass, and an outside ambient
temperature thermometer is an available factory-in-
stalled option on this model. Refer to 8W-49 - Over-
head Console in Group 8W - Wiring Diagrams for
complete circuit descriptions and diagrams.
NOTE: This group covers both Left-Hand Drive
(LHD) and Right-Hand Drive (RHD) versions of this
model. Whenever required and feasible, the RHD
versions of affected vehicle components have been
constructed as mirror-image of the LHD versions.
While most of the illustrations used in this group
represent only the LHD version, the diagnostic and
service
procedures outlined can generally be
applied to either version. Exceptions to this rule
have been clearly identified as LHD or RHD, if a
special illustration or procedure is required.
OVERHEAD CONSOLE
The overhead console for this model includes a
mini trip computer, an electronic compass, and an
outside ambient temperature thermometer. The over-
head console also houses two front-mounted and two
rear-mounted reading and courtesy lamps, a garage
door opener storage bin, and a sunglasses storage
bin.
On models equipped with the Remote Keyless
Entry (RKE) option, the RKE receiver is also located
within the overhead console housing. Refer to Group
8P - Power Lock Systems for more information on
this feature.
Following are general descriptions of the major
components used in the overhead console. Refer to
the owner’s manual in the vehicle glove box for more
information on the features, use and operation of the
various overhead console components.
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.
