Chrysler Le Baron, Dodge Dynasty, Plymouth Acclaim. Manual

(5) For installation reverse above procedures. Seat

sensor assembly by hand to insure proper gear en-
gagement. Tighten retaining bolt to 7 N

Im (60 in.

lbs.) torque.

ELECTRONIC AUTOMATIC TRANSAXLE
VEHICLE SPEED SENSOR REPLACEMENT

The output vehicle speed sensor is located to the

left of the manual shift lever.

(1) Raise and support vehicle on safety stands.
(2) Remove vehicle speed sensor (Fig. 27).
(3) For installation, reverse above procedures.

VEHICLE SPEED SENSOR TEST

For testing of the vehicle speed and related compo-

nents, refer to the Powertrain Diagnostics Test Pro-
cedure Manual.

PRINTED CIRCUIT BOARD REPLACEMENT

(1) Remove cluster assembly, refer to Cluster As-

sembly Replacement.

(2) Twist out all lamp sockets.
(3) Remove screws securing printed circuit board

to cluster housing (Fig. 11).

(4) Pull printed circuit board straight out and

avoid bending the board.

(5) For installation reverse above procedures. Be

sure that all gauge pins are carefully aligned.

CLUSTER LAMPS REPLACEMENT

All cluster lamps are one-piece lamp and socket as-

semblies. Can be replaced by removing cluster as-
sembly from instrument panel. Replace appropriate
lamp shown in rear view of cluster (Fig. 28).

ELECTRONIC CLUSTER

SELF DIAGNOSTIC SYSTEM

The electronic clusters have an internal diagnostics

routing to isolate problems within the cluster or CCD
Bus.

Using the cluster Self-Diagnostic Test will deter-

mine whether the problem is within the cluster or
outside of cluster (Fig. 29 and 30).

Successful completion of the Self Diagnostic Test

indicates that the problem is in the CCD Bus, inter-
facing modules, connectors, or sensors outside of the
cluster. Refer to Fig. 31 for terminal listing.

CONDITION: CLUSTER DISPLAYS DO NOT
ILLUMINATE AFTER VEHICLE IS STARTED

PROCEDURE

(1) Check fuses and verify battery and ignition

voltage at cluster connector.

(2) Check ground from cluster connector to instru-

ment panel ground stud.

CONDITION: CLUSTER ASTERISK (*)
FLASHES, CLUSTER DISPLAYS NOT
INDICATING CORRECT DATA.

PROCEDURE

CCD bus problem. Use the Body Chassis Diagnos-

tic Manual to diagnose CCD Bus.

CONDITION: SPEEDOMETER AND ODOMETER
ARE INOPERATIVE OR OPERATES
INTERMITTENTLY

PROCEDURE

(1) If speedometer reads 0, or odometer is blank,

and cluster asterisk is flashing, use the Body Chassis
Diagnostic Manual to diagnose CCD Bus problem.

(2) If cluster asterisk is not flashing, check for de-

fective vehicle speed sensor or speed sensor wiring.

CONDITION: OIL GAUGE, FUEL GAUGE,
TEMPERATURE GAUGE, OR VOLTAGE GAUGE
INOPERATIVE

PROCEDURE

If any gauge gives no indication and cluster aster-

isk is flashing, use the Body Chassis Manual to diag-
nose CCD Bus problem.

If cluster asterisk is not flashing:
(1) Check for defective sending unit or wiring.

(a) Sending units and wiring can be checked by

grounding the connector leads, at the sending unit,
in the vehicle.

(b) With the ignition in the ON position, a

grounded input will cause the oil, fuel, or temper-
ature gauge to read maximum.

(2) If the problem is with the oil, temperature, or

fuel gauge, check the body controller. If the problem
is with the voltage gauge, check the powertrain con-
trol module operation.

CONDITION: CLUSTER DISPLAY DOES NOT
DIM WHEN HEADLAMP SWITCH IS
ACTIVATED AND RHEOSTAT ROTATED

PROCEDURE

If the cluster asterisk is flashing, Refer to the Body

Chassis Diagnostic Manual to diagnose the CCD Bus.

If the cluster asterisk is not flashing:
(1) Check fuses in headlamp circuit.
(2) Check for loose connections or defective wiring

for headlamp switch to body controller.

(3) Check for defective headlamp switch. The elec-

tronic instrument cluster receives the display inten-
sity status from the body controller via the CCD Bus.

CONDITION: SEAT BELT WARNING LAMP
DOES NOT ILLUMINATE

PROCEDURE

Turn on ignition. Lamp should illuminate for six

seconds. If not:

(1) Check for burned out lamp and retest.
(2) Replace cluster.

CONDITION: LOW WASHER, DOOR/DECK, OR
MALFUNCTION INDICATOR (CHECK ENGINE)
LAMP, DO NOT ILLUMINATE

PROCEDURE

(1) Perform cluster self-diagnostics to determine if

lamp will illuminate. If lamp does not, check for
burned out lamp, replace and retest.

(2) If cluster asterisk is flashing, Refer to the Body

Chassis Diagnostic Manual to diagnose CCD Bus.

(3) If cluster asterisk is not flashing:

(a) For low washer fluid or door/deck, check in-

puts to body controller.

(b) For malfunction indicator (check engine),

check powertrain control module operation.

CONDITION: ODOMETER DISPLAY IS BLANK.
THE ODOMETER VALUE IS NO LONGER
RETAINED IN THIS ELECTRONIC CLUSTER.
THIS TAKES PLACE IN THE BODY
CONTROLLER

PROCEDURE

(1) If cluster asterisk is flashing, Refer to the Body

Chassis Diagnostic Manual to diagnose CCD Bus.

(2) If cluster asterisk is not flashing, perform clus-

ter self-diagnostics. If code 921 appears in the odom-
eter display, replace body controller for odometer
failure.
