TEST 1
Test 1 determines of the antenna mast is insulated
from the base. Proceed as follows:
(1) Unplug the antenna coaxial cable from the
radio chassis and isolate. Remove the antenna mast.
(2) Connect an ohmmeter test lead to the inside
center of the antenna base. Connect the other test
lead to a metallic portion on the outside of the
antenna base. Check for continuity.
(3) There should be no continuity. If continuity is
found, replace the faulty or damaged antenna base
and cable assembly.
TEST 2
Test 2 checks the antenna for an open circuit as
follows:
(1) Unplug the antenna coaxial cable connector
from the radio chassis. Remove the antenna mast.
The painted mast prevents measurement directly
through the mast.
(2) Connect an ohmmeter test lead to the inside
center of the antenna base. Connect the other test
lead to the center pin of the antenna coaxial cable
connector.
(3) Continuity should exist (the ohmmeter should
only register a fraction of an ohm). High or infinite
resistance indicates damage to the base and cable
assembly. Replace the faulty base and cable if
required.
TEST 3
Test 3 checks the condition of the ground between
the antenna base and the vehicle body as follows:
(1) Connect one ohmmeter test lead to the fender
on an exposed metal area (paint and e-coat must be
penetrated to obtain continuity). Connect the other
test lead to the outer crimp on the antenna coaxial
cable connector.
(2) The resistance should be less than (1) ohm.
(3) If the resistance is more than (1) ohm, clean
and/or tighten the antenna base to the fender mount-
ing hardware.

DIAGNOSIS AND TESTING
If the vehicle is equipped with remote radio
switches located on the backs of the steering wheel
spokes, and the problem being diagnosed is related to
one of the symptoms listed below, be certain to check
the remote radio switches and circuits as described
in this group, prior to attempting radio diagnosis or
repair.
²Stations changing with no remote radio switch
input
²Radio memory presets not working properly
²Volume changes with no remote radio switch
input
²Remote radio switch buttons taking on other
functions
²CD player skipping tracks
²Remote radio switch inoperative.
For circuit descriptions and diagrams, 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.

CAUTION:
The speaker output of the radio is a ªfloating
groundº system. Do not allow any speaker lead to
short to ground, as damage to the radio may result.
(1) Check the fuse(s) in the junction block and the
Intelligent Power Module. If OK, go to Step 2. If not
OK, repair the shorted circuit or component as
required and replace the faulty fuse(s).

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.

RSCHIME/BUZZER8B-1

OPERATION
The Body Control Module (BCM) is designed to
control and integrate many of the electronic features
and functions of the vehicle. The microprocessor-
based BCM hardware and software monitors many
hard wired switch and sensor inputs as well as those
resources it shares with other electronic modules in
the vehicle through its communication over the PCI
data bus network. The internal programming and all
of these inputs allow the BCM microprocessor to
determine the tasks it needs to perform and their
priorities, as well as both the standard and optional
features that it should provide. The BCM program-
ming then performs those tasks and provides those
features through both PCI data bus communication
with other electronic modules and through hard
wired low current outputs to a number of relays.
These relays provide the BCM with the ability to
control numerous high current accessory systems in
the vehicle.
The BCM monitors its own internal circuitry as
well as many of its input and output circuits, and
will store a Diagnostic Trouble Code (DTC) in elec-
tronic memory for any failure it detects. These DTCs
can be retrieved and diagnosed using a DRBIIItscan
tool. Refer to the appropriate diagnostic information.
REMOVAL
(1) Disconnect and isolate the battery negative
cable.
(2) Remove lower steering column cover and knee
blocker reinforcement.
(3) Disconnect two wire connectors from bottom of
Body Control Module (BCM)
(4) Remove bolts holding the BCM to the dash
panel mounting bracket.
(5) Remove the BCM from the mounting bracket.
INSTALLATION
(1) Install the BCM onto the mounting bracket.
(2) Install the bolts holding the BCM to dash
panel mounting bracket.
(3) Connect two wire connectors to the bottom of
the BCM.
(4) Install the lower steering column cover and
knee blocker reinforcement.
(5) Connect the battery negative cable.
CONTROLLER ANTILOCK
BRAKE
DESCRIPTION
The controller antilock brake (CAB) is a micropro-
cessor-based device which monitors the antilock
brake system (ABS) during normal braking and con-trols it when the vehicle is in an ABS stop. The CAB
is mounted to the HCU as part of the integrated con-
trol unit (ICU) (Fig. 1). The CAB uses a 24-way elec-
trical connector on the vehicle wiring harness. The
power source for the CAB is through the ignition
switch in the RUN or ON position. The CAB is on
the PCI bus.
OPERATION
The primary functions of the controller antilock
brake (CAB) are to:
²Monitor the antilock brake system for proper
operation.
²Detect wheel locking or wheel slipping tenden-
cies by monitoring the speed of all four wheels of the
vehicle.
²Control fluid modulation to the wheel brakes
while the system is in an ABS mode.
²Store diagnostic information.
²Provide communication to the DRBIIItscan tool
while in diagnostic mode.
²Illuminate the amber ABS warning indicator
lamp.
²(With traction control only) Illuminate the TRAC
ON lamp in the message center on the instrument
panel when a traction control event occurs.
²(with traction control only) Illuminate the TRAC
OFF lamp when the amber ABS warning indicator
lamp illuminates.
The CAB constantly monitors the antilock brake
system for proper operation. If the CAB detects a
fault, it will turn on the amber ABS warning indica-
tor lamp and disable the antilock braking system.

RSELECTRONIC CONTROL MODULES8E-3
BODY CONTROL MODULE (Continued)

The normal base braking system will remain opera-
tional.
NOTE: If the vehicle is equipped with traction con-
trol, the TRAC OFF lamp will illuminate anytime the
amber ABS warning indicator lamp illuminates.
The CAB continuously monitors the speed of each
wheel through the signals generated by the wheel
speed sensors to determine if any wheel is beginning
to lock. When a wheel locking tendency is detected,
the CAB commands the CAB command coils to actu-
ate. The coils then open and close the valves in the
HCU that modulate brake fluid pressure in some or
all of the hydraulic circuits. The CAB continues to
control pressure in individual hydraulic circuits until
a locking tendency is no longer present.
The CAB contains a self-diagnostic program that
monitors the antilock brake system for system faults.
When a fault is detected, the amber ABS warning
indicator lamp is turned on and the fault diagnostic
trouble code (DTC) is then stored in a diagnostic pro-
gram memory. These DTC's will remain in the CAB
memory even after the ignition has been turned off.
The DTC's can be read and cleared from the CAB
memory by a technician using the DRBIIItscan tool.
If not cleared with a DRBIIItscan tool, the fault
occurrence and DTC will be automatically cleared
from the CAB memory after the identical fault has
not been seen during the next 3,500 miles.
