SPARK PLUG CABLE SERVICEÐ3.3/3.8L ENGINES
WARNING: The ignition cables should not be
removed while the engine is hot. This could cause
sever injury/burns and can cause damage to the
ignition cables.
The spark plug boot heat shield needs to be
installed correctly on the boot before being installed

DIAGNOSIS AND TESTING
DIAGNOSTIC PROCEDURES
NS vehicle instrument clusters are equipped with a
self diagnostic test feature to help identify electronic
problems. Prior to any test, perform Self Diagnostic
Test. The self diagnostic system monitors the CCD
bus messages. If an electronic problem occurs, a
Diagnostic Trouble Code (DTC) will be displayed in
the odometer window of the cluster.
The following CCD bus messages are continuously
monitored by the diagnostic system:
²Body Control Module
²Powertrain Control Module
²Transmission Control Module, if equipped
HEADLAMP SWITCH
Using a Digital Multimeter, equipped with a diode
test to perform the Headlamp Switch Test below (Fig.
1).
Switch position possibilities are open (no continu-
ity), continuity, resistance value in ohms, or diode
test. Use the values in the third column to determine
meter setting. If Headlamp Switch is not within spec-
ifications replace as necessary.
The Chrysler Town and Country is available with
optional Automatic Headlamps. For diagnosis, refer
to the proper Body Diagnostic Procedures Manual.
SELF DIAGNOSTIC TEST
To activate self diagnostic program:
(1) With the ignition switch in the OFF position,
depress the TRIP and RESET buttons.
(2) While holding the TRIP and RESET button
turn the ignition switch to the ON position.
(3) Continue to hold the TRIP and RESET buttons
until the word CODE appears in the odometer win-
dows (about five seconds) then release the buttons. If
a problem exists, the system will display Diagnostic
Trouble Codes (DTC's). If no problem exists, the code
999 (End Test) will momentarily appear.
DIM TEST
When CHEC-0 is displayed in the odometer win-
dow, the cluster's vacuum fluorescent (VF) displayswill dim down. If the VF display brightness does no
change, a problem exists in the cluster.

REMOTE RADIO SWITCHES
A remote radio control switch option is available on
LXI models sold in North America with the AM/FM/
cassette/5-band graphic equalizer with CD changer
control feature (RBN sales code), or the AM/FM/CD/
cassette/3-band graphic equalizer (RAZ sales code)
radio receivers. Two rocker-type switches are
mounted on the back (instrument panel side) of the
steering wheel spokes. The switch on the left spoke is
the seek switch and has seek up, seek down, and pre-
set station advance functions. The switch on the
right spoke is the volume control switch and has vol-
ume up, and volume down functions (Fig. 6).
These switches are resistor multiplexed units that
are hard-wired to the Body Control Module (BCM)
through the clockspring. The BCM sends the propermessages 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.
NAME BRAND SPEAKER RELAY
Relay is located in the junction block. To test relay
refer to the Audio Diagnostic Test Procedures or use
a known good relay.

BAGS, REFER TO GROUP 8M - PASSIVE
RESTRAINT SYSTEMS BEFORE ATTEMPTING ANY
STEERING WHEEL, STEERING COLUMN, OR
INSTRUMENT PANEL COMPONENT DIAGNOSIS OR
SERVICE. FAILURE TO TAKE THE PROPER PRE-
CAUTIONS COULD RESULT IN ACCIDENTAL AIR-
BAG DEPLOYMENT AND POSSIBLE PERSONAL
INJURY.
The following four tests are used to diagnose the
antenna with an ohmmeter:
²Test 1- Mast to ground test
²Test 2- Tip-of-mast to tip-of-conductor test
²Test 3- Body ground to battery ground test
²Test 4- Body ground to coaxial shield test.
The ohmmeter test lead connections for each test
are shown in Antenna Tests (Fig. 7).
NOTE: This model has a two-piece antenna coaxial
cable. Tests 2 and 4 must be conducted in two
steps to isolate a coaxial cable problem; from the
coaxial cable connection under the right end of the
instrument panel near the right cowl side panel to
the antenna base, and then from the coaxial cable
connection to the radio chassis connection.
TEST 1
Test 1 determines if the antenna mast is insulated
from the base. Proceed as follows:
(1) Unplug the antenna coaxial cable connector
from the radio chassis and isolate.
(2) Connect one ohmmeter test lead to the tip of
the antenna mast. Connect the other test lead to 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.

DESCRIPTION AND OPERATION (Continued)

TEST 2
Test 2 checks the antenna for an open circuit as
follows:
(1) Unplug the antenna coaxial cable connector
from the radio chassis.
(2) Connect one ohmmeter test lead to the tip of
the antenna mast. 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 vehicle body
ground connection. This test should be performed
with the battery positive cable removed from the bat-
tery. Disconnect both battery cables, the negative
cable first. Reconnect the battery negative cable and
perform the test as follows:
(1) Connect one ohmmeter test lead to the vehicle
fender. Connect the other test lead to the battery
negative post.
(2) The resistance should be less than (1) ohm.
(3) If the resistance is more than (1) ohm, check
the braided ground strap connected to the engine and
the vehicle body for being loose, corroded, or dam-
aged. Repair the ground strap connection, if required.
TEST 4
Test 4 checks the condition of the ground between
the antenna base and the vehicle body as follows:(1) Connect one ohmmeter test lead to the vehicle
fender. Connect the other test lead to the outer crimp
on the antenna coaxial cable connector.
(2) The resistance should be less then (1) ohm.
(3) If the resistance is more then (1) ohm, clean
and/or tighten the antenna base to fender mounting
hardware.

DIAGNOSIS AND TESTING (Continued)

(1) Check the fuse(s) in the junction block and the
Power Distribution Center (PDC). If OK, go to Step
2. If not OK, repair the shorted circuit or component
as required and replace the faulty fuse(s).

PDC. If OK, go to Step 3. If not OK, repair the open
circuit to the battery as required.
(3) Turn the ignition switch to the ON position.
Check for battery voltage at the fuse in the junction
block. If OK, go to Step 4. If not OK, repair the open
circuit to the ignition switch as required.
(4) Turn the ignition switch to the OFF position.
Disconnect and isolate the battery negative cable.
Remove the instrument cluster center bezel. Remove
the radio, but do not unplug the wire harness connec-
tors. Check for continuity between the radio chassis
and a good ground. There should be continuity. If
OK, go to Step 5. If not OK, repair the open radio
chassis ground circuit as required.
(5) Connect the battery negative cable. Turn the
ignition switch to the ON position. Check for battery
voltage at the fused ignition switch output circuit
cavity of the left (gray) radio wire harness connector.
If OK, go to Step 6. If not OK, repair the open circuit
as required.
(6) Turn the ignition switch to the OFF position.
Check for battery voltage at the fused B(+) circuit
cavity of the left (gray) radio wire harness connector.
