GENERAL INFORMATION
INTRODUCTION
This group covers the chime warning system,
which is standard factory-installed equipment on this
model. Refer to 8W-40 Instrument Cluster or 8W-44 -
Interior Lighting 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.
CHIME WARNING SYSTEM
The chime warning system provides an audible
warning to the driver under the following conditions:
• Driver side seat belt is not fastened (chimes will
sound after the ignition switch is turned to the On
position for the duration of the seat belt reminder
lamp illumination or until the driver side seat belt is
buckled, whichever occurs first)
• Engine coolant temperature is high
• Head or park lamps are turned on with the igni-
tion switch Off and the driver side front door open
• Key is in the ignition switch with the ignition
switch Off and the driver side front door open
• Low fuel warning lamp illumination - less than
about one-eighth tank of fuel remaining
• Overhead console trip computer is reset
• The optional Sentry Key Immobilizer System
(SKIS) is in the “customer programming” mode.
Following are general descriptions of the major
components in the chime warning system. Refer to
the owner’s manual in the vehicle glove box for more
information on the features, use and operation of the
chime warning system.
DESCRIPTION AND OPERATION
INSTRUMENT CLUSTER
The instrument cluster is an electromechanical
unit that contains integrated circuitry and internal
programming to perform a variety of functions. The
instrument cluster circuitry monitors hard-wired
switch inputs, as well as message inputs received
from other vehicle electronic modules on the Chrysler
Collision Detection (CCD) data bus network.
The instrument cluster uses these many inputs
along with its internal programming and an integral
chime tone generator to perform the functions of the
chime warning module on this model. The instru-
ment cluster circuitry also has a self-diagnostic capa-
bility. Refer to Group 8E - Instrument Panel Systems
for more information on this feature.
Hard-wired chime warning system inputs to the
instrument cluster include the following:
• Driver door jamb switch
• Driver seat belt switch
• Headlamp switch
• Key-in ignition switch.
The only instrument cluster diagnosis found in this
group consists of confirming the viability of the hard-
wired chime request inputs to the instrument cluster
circuitry. For diagnosis of the CCD data bus and the
