CD changer CHRYSLER VOYAGER 2001 Owner's Manual

CD CHANGER
DESCRIPTION
The 4 Disc In-Dash CD Changer (if equipped) is
located in the instrument panel below the radio. The
remote changer does not use a cartridge or magazine
for the CD's. Up to 4 CD's can be directly loaded into
this unit.
OPERATION
Due to its compact design, the CD changer can
carry out only one operation at a time. For example,
you can not load a new disc while playing another at
the same time. Each operation happens sequentially.
The radio unit provides control over all features of
the CD changer with the exception of the CD load
and eject functions, which are controlled by buttons
located on the front of the CD changer. All features
you would expect, such as Disc Up/Down, Track
Up/Down, Random and Scan are controlled by the
radio, which also displays all relevant CD changer
information on the radio display.
The CD changer contains a Load/Eject button and
an indicator LED for each of the four disc positions
as well as an illuminated disc opening. The individ-
ual LED indicates whether a CD is currently loaded
in that particular chamber of the CD changer. Press-
ing the individual Load/Eject button for a particular
chamber will eject a disc currently present in that
chamber. If the chamber is currently empty, actuat-
ing the Load/Eject button will position that chamber
to receive and load a new disc in that chamber.
REMOVAL
(1) Disconnect and isolate the battery negative
cable.
(2) Remove screws holding CD changer.
(3) Disconnect the wire connector from the back of
the CD changer.
(4) Remove the CD changer from the vehicle (Fig.
5).
INSTALLATION
(1) Reconnect the wire connector to the CD
changer.
(2) Insert the CD changer into the instrument
panel.
NOTE: Use care when inserting CD changer so that
cable is not pinched or trapped against instrument
panel.
(3) Install screws holding CD changer.
(4) Reconnect the battery negative cable.
CHOKE
DIAGNOSIS AND TESTING
If the audio system is cutting in and out at higher
volumes, check for continuity across the choke con-
nector. If no continuity, replace the choke assembly.
The choke is located on the junction block/body con-
trol module.
D-PILLAR SPEAKER
REMOVAL
PASSENGER SIDE
(1) Disconnect and isolate the battery negative
cable.
(2) Remove rear header trim.
(3) Remove liftgate scuff plate.
(4) Remove upper seat belt bolt. (Refer to 8 -
ELECTRICAL/RESTRAINTS/SEAT BELT OUT-
BOARD FRONT - REMOVAL).
(5) Partially remove quarter trim panel to access
the D-pillar speaker.
(6) Slide the speaker from the retainer (Fig. 6).
(7) Disconnect the wire harness connector from the
speaker.
DRIVER SIDE
(1) Disconnect and isolate the negative battery
cable.

REMOTE SWITCHES
DESCRIPTION
A remote radio control switch option is available on
some models. Two rocker-type switches are mounted
on the back (instrument panel side) of the steering
wheel spokes (Fig. 15). The switch on the left spoke
is the seek switch and has seek up, seek down, and
preset station advance functions. The switch on the
right spoke is the volume control switch and has vol-
ume up, and volume down functions. The switch on
the right spoke also includes a ªmodeº control that
allows the driver to sequentially select AM radio, FM
radio, cassette player, CD player or CD changer (if
equipped).
OPERATION
These switches are resistor multiplexed units that
are hard-wired to the Body Control Module (BCM)
through the clockspring. The BCM sends the proper
messages on the Chrysler Collision Detection (CCD)
data bus network to the radio receiver. For diagnosis
of the BCM or the CCD data bus, the use of a DRB
scan tool and the proper Diagnostic Procedures man-
ual are recommended. For more information on the
operation of the remote radio switch controls, refer to
the owner's manual in the vehicle glove box.

DESCRIPTION
This transaxle combines torque converter, three
speed transmission, final drive gearing, and differen-
tial into a front wheel drive system.
Within this transaxle, there are three primary
areas:
(1) Main center line plus valve body.
(2) Transfer shaft center line (includes governor
and parking sprag).
(3) Differential center line.
Center distances between the main rotating parts
in these three areas are held precise to maintain a
low noise level.
The torque converter, transaxle area, and differen-
tial are housed in an integral aluminum die casting.
The differential oil sump is common with the
transaxle sump. Separate filling of the differen-
tial is NOT necessary.
The torque converter is attached to the crankshaft
through a flexible driving plate. Cooling of the con-
verter is accomplished by circulating the transaxle
fluid through a remote cooler. There are two types of
coolers used. An oil-to-water type cooler located in
the radiator side tank and/or an oil-to-air heat
exchanger. The torque converter assembly is a sealed
unit that cannot be disassembled.
The transaxle fluid is filtered by an internal filter
attached to the lower side of the valve body assembly.Engine torque is transmitted to the torque con-
verter and then through the input shaft to multiple-
disc clutches in the transaxle. The power flow
depends on the application of the clutches and bands.
Refer to Elements in Use Chart in Diagnosis and
Tests section.
The transaxle consists of:
²Two multiple-disc clutches
²An overrunning clutch
²Two servos
²A hydraulic accumulator
²Two bands
²Two planetary gear sets
This provides three forward ratios and a reverse
ratio. The common sun gear of the planetary gear
sets is connected to the front clutch by a driving
shell. The driving shell is splined to the sun gear and
front clutch retainer. The hydraulic system consists
of an oil pump and a single valve body which con-
tains all of the valves except the governor valves.
The transaxle sump and differential sump are both
vented through the dipstick. Output torque from the
main center line is delivered through helical gears to
the transfer shaft. This gear set is a factor in the
transaxle final drive (axle) ratio. The shaft also car-
ries the governor and parking sprag. An integral heli-
cal gear on the transfer shaft drives the differential
ring gear.
