RADIO CHOKE RELAY
DESCRIPTION
Models equipped with the Infinity premium
speaker package have a filter, choke, and speaker
relay unit. The filter, choke, and speaker relay unit is
mounted to the lower instrument panel center brace,
inboard of the Central Timer Module (CTM) and
directly above the 16-way data link connector. The
filter, choke, and speaker relay unit can be accessed
for service without instrument panel disassembly or
removal.
The filter, choke, and speaker relay unit should be
checked if there is no sound output noted from the
speakers. The filter, choke, and speaker relay unit
cannot be repaired or adjusted and, if faulty or dam-
aged, the unit must be replaced.
OPERATION
The filter, choke, and speaker relay unit is used to
control the supply of fused battery current to the
front door speaker-mounted dual amplifiers. The
speaker relay is energized by a fused 12 volt output
from the radio receiver whenever the radio is turned
on. For complete circuit diagrams, refer to the appro-
priate wiring information. The wiring information
includes wiring diagrams, proper wire and connector
repair procedures, details of wire harness routing
and retention, connector pin-out information andlocation views for the various wire harness connec-
tors, splices and grounds.
DIAGNOSIS AND TESTING - RADIO CHOKE
RELAY
The filter, choke and speaker relay is used to
switch power to the individual speaker amplifiers
used with the Infinity premium speaker package.
The choke and relay are serviced only as a unit. If all
of the speakers are inoperative the filter, choke and
speaker relay unit should be considered suspect.
However, before replacement make the following
checks of the filter, choke and speaker relay circuits.
For complete circuit diagrams, refer to the appropri-
ate wiring information. The wiring information
includes wiring diagrams, proper wire and connector
repair procedures, details of wire harness routing
and retention, connector pin-out information and
location views for the various wire harness connec-
tors, splices and grounds.

in the junction block. If OK, go to Step 3. If not OK,
repair the open fused B(+) circuit to the battery as
required.
(3) Disconnect the instrument panel wire harness
connector from the filter, choke and speaker relay
unit. Check for battery voltage at the fused B(+) cir-
cuit cavity of the instrument panel wire harness con-
nector for the filter, choke and speaker relay unit. If
OK, go to Step 4. If not OK, repair the open fused
B(+) circuit to the junction block fuse as required.
(4) Probe the ground circuit cavity of the instru-
ment panel wire harness connector for the filter,
choke and speaker relay unit. Check for continuity to
a good ground. There should be continuity. If OK, go
to Step 5. If not OK, repair the open ground circuit to
ground as required.
(5) Turn the ignition switch to the On position and
turn the radio on. Check for battery voltage at the
radio 12-volt output circuit cavity of the instrument
panel wire harness connector for the filter, choke and

²Wiper motor.
If the source of RFI or EMI noise is identified as a
component on the vehicle (i.e., generator, blower
motor, etc.), the ground path for that component
should be checked. If excessive resistance is found in
any ground circuit, clean, tighten, or repair the
ground circuits or connections to ground as required
before considering any component replacement.
For service and inspection of secondary ignition
components, refer to Electrical, Ignition Control.
Inspect the following secondary ignition system com-
ponents:
²Distributor cap and rotor
²Ignition coil
²Spark plugs
²Spark plug wire routing and condition.
Reroute the spark plug wires or replace the faulty
components as required.
If the source of the RFI or EMI noise is identified
as two-way mobile radio or telephone equipment,
check the equipment installation for the following:
²Power connections should be made directly to
the battery, and fused as closely to the battery as
possible.
²The antenna should be mounted on the roof or
toward the rear of the vehicle. Remember that mag-
netic antenna mounts on the roof panel can adversely
affect the operation of an overhead console compass,
if the vehicle is so equipped.
²The antenna cable should be fully shielded coax-
ial cable, should be as short as is practical, and
should be routed away from the factory-installed
vehicle wire harnesses whenever possible.
²The antenna and cable must be carefully
matched to ensure a low Standing Wave Ratio
(SWR).
Fleet vehicles are available with an extra-cost RFI-
suppressed Powertrain Control Module (PCM). This
unit reduces interference generated by the PCM on
some radio frequencies used in two-way radio com-
munications. However, this unit will not resolve com-
plaints of RFI in the commercial AM or FM radio
frequency ranges.

COMMUNICATION
DESCRIPTION - CCD DATA BUS
The Chrysler Collision Detection (also referred to
as CCD or C2D ) data bus system is a multiplex sys-
tem used for vehicle communications on many
Chrysler Corporation vehicles. Within the context of
the CCD system, the term ªcollisionª refers to the
system's ability to avoid collisions of the electronic
data that enters the data bus from various electronic
control modules at approximately the same time.
Multiplexing is a system that enables the trans-
mission of several messages over a single channel or
circuit. Many Chrysler vehicles use this principle for
communication between the various microprocessor-
based electronic control modules.
Many of the electronic control modules in a vehicle
require information from the same sensing device. In
the past, if information from one sensing device was
required by several controllers, a wire from each con-
troller needed to be connected in parallel to that sen-
sor. In addition, each controller utilizing analog
sensors required an Analog/Digital (A/D) converter in
order to ªreadª these sensor inputs. Multiplexing
reduces wire harness complexity, sensor current
loads and controller hardware because each sensing
device is connected to only one controller, which
reads and distributes the sensor information to the
other controllers over the data bus. Also, because
each controller on the data bus can access the con-
troller sensor inputs to every other controller on the
data bus, more function and feature capabilities are
possible.

BATTERY HOLDDOWN
DESCRIPTION
The battery hold down hardware (Fig. 18) includes
two bolts, two U-nuts and a hold down strap. The bat-
tery hold down bracket consists of a formed steel rod
with a stamped steel angle bracket welded to each end.
The hold down bracket assembly is then plastic-coated
for corrosion protection. Models equipped with the
optional diesel engine have a second battery installed
in a second battery tray on the right side of the engine
compartment. The hold down hardware for the rightside battery is mirror image of the hold down hard-
ware used for the left side battery.
When installing a battery into the battery tray, be
certain that the hold down hardware is properly
installed and that the fasteners are tightened to the
proper specifications. Improper hold down fastener
tightness, whether too loose or too tight, can result in
damage to the battery, the vehicle or both. Refer to
