GENERAL INFORMATION
INTRODUCTION
Power operated and heated outside rear view mir-
rors are standard factory-installed equipment on this
model. Following are general descriptions of the
major components in the power mirror system. Refer
to 8W-62 - Power Mirrors in Group 8W - Wiring Dia-
grams for complete circuit descriptions and diagrams.
MEMORY SYSTEM
An electronic memory system is an available option
on this model. The memory system is able to store
and recall the driver’s power seat positions (including
power lumbar and recliner positions), both outside
power mirror positions, and ten radio station presets
(including last station tuned) for two drivers. The
memory system will automatically return to all of
these settings when the corresponding button (Driver
1 or 2) of the memory switch on the driver’s front
door trim panel is depressed, or when the doors are
unlocked using the corresponding (Driver 1 or 2)
Remote Keyless Entry (RKE) transmitter.
The Driver Door Module (DDM) receives hard-
wired input from the memory set/select switch on the
driver’s front door trim panel. The DDM also receives
messages on the Chrysler Collision Detection (CCD)
data bus network from the Remote Keyless Entry
(RKE) receiver in the Passenger Door Module (PDM)
for the memory select function. The DDM processes
these inputs and sends messages to the radio, the
PDM, and the Memory Seat Module (MSM) on the
CCD data bus for memory recall.
The CCD data bus network allows the sharing of
sensor information. This helps to reduce wiring 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.
This group covers only the diagnostic procedures
for the conventional power mirror system compo-
nents. For additional information on the features and
functions of the memory system, refer to the vehicle
owner’s manual. For diagnosis of the memory system,
use of a DRB scan tool and the proper Body Diagnos-
tic Procedures Manual are recommended.
DESCRIPTION AND OPERATION
POWER MIRROR
The power mirrors are connected to battery feed at
all times. Each mirror head contains two electric
motors, two drive mechanisms, an electric heating
element, horizontal and vertical position sensors for
the memory system option, and the mirror glass. One
motor and drive controls mirror up-and-down move-
