NOTE: Pinion depth shims are placed between the
rear pinion bearing and the pinion gear head to
achieve proper ring and pinion gear mesh. If ring
and pinion gears are reused, the pinion oil slinger/
depth shim should not require replacement. Refer
to Adujstments (Pinion Gear Depth) to select the
proper thickness shim before installing pinion gear.

CD CHANGER
DESCRIPTION
A factory-installed Compact Disc (CD) changer fea-
turing a six-CD magazine is an available option on
this model. The CD changer is mounted in the cargo
area of the passenger compartment on the right rear
quarter panel.
The controls on the radio receiver operate the CD
changer through messages sent over the Programma-
ble Communications Interface (PCI) data bus net-
work. For diagnosis of the messaging functions of the
radio receiver and the CD changer, or of the PCI data
bus, a DRB scan tool and the proper Diagnostic Pro-
cedures manual are required.
The CD changer can only be serviced by an autho-
rized radio repair station. See the latest Warranty
Policies and Procedures manual for a current listing
of authorized radio repair stations. Refer to the
appropriate wiring information. The wiring informa-
tion includes wiring diagrams, proper wire and con-
nector repair procedures, details of wire harness
routing and retention, connector pin-out information
and location views for the various wire harness con-
nectors, splices and grounds.
OPERATION
The CD changer will only operate when the igni-
tion switch is in the On or Accessory positions, and
the radio is turned on. The six-CD magazine may be
ejected with the ignition in the Off position. For more
information on the features, loading procedures and
radio control functions for the operation of the CD
changer, refer to the owner's manual.
REMOVAL
(1) Disconnect and isolate the battery negative
cable.
(2) Remove the right rear quarter trim panel.
(Refer to 23 - BODY/INTERIOR/QUARTER TRIM
PANEL - REMOVAL).
