GENERAL INFORMATION
MECHANICAL CLUSTER
The mechanical cluster includes a fuel, oil pres-
sure, coolant temperature, and voltmeter gauges. All
incorporate magnetic type gauges. When the ignition
switch is in the OFF position, the gauges will show a
reading; however, the readings are only accurate
when the ignition switch is in the ON position. The mechanical cluster also includes an electric
speedometer, driven by pulses from the vehicle speed
sensor (Fig. 1).
ELECTRONIC CLUSTER
The electronic cluster is easily distinguished from
the mechanical cluster by its digital and linear dis-
play. The electronic cluster includes:
² Oil pressure gauge
² Coolant temperature gauge
² Voltmeter
² Fuel gauge
The electronic cluster receives virtually all of its
information to display from the body controller and
powertrain control module via the Chrysler Collision
Detection (CCD) Serial Data Bus. The odometer
memory is no longer retained in the cluster. This is
now retained in the body controller (Fig. 2).
ELECTRONIC CLUSTER DIMMING
The electronic cluster display is dimmed from day-
time to night time intensity when the headlamp
switch is turned on. This intensity can be controlled
using the headlamp switch rheostat. An additional detent on the headlamp switch rheo-
stat will allow daytime intensity while driving with
headlamps on during the daytime.
WARNING LAMPS
The mechanical instrument cluster will have warn-
ing lamps for six systems. These include brake sys-
tem, air bag, seat belt, low fuel, anti-lock for optional
anti-lock brake system, and malfunction indicator
(check engine) lamp. The cluster also includes check
gages indicator which will illuminate in a warning
situation. This will notify driver to check for a prob-
lem in coolant temperature, oil pressure, or electrical
systems. The electronic cluster will have warning indicator
lamps for eight different systems. These include:
² Air Bag
² Low washer fluid
² Door/deck lid ajar
² Malfunction Indicator (Check engine) Lamp
² Brake system
² Seat belt
² Anti-lock (ABS) for optional anti-lock brake sys-
tem
² Check gages, monitors engine coolant, oil pressure
and electrical charging system failures. In addition, ISO symbol will flash to notify the
driver in event of:
² Low fuel
² High temperature
² Low oil pressure
² Charging system failure

off, there should be continuity in the system. Start
the engine. With the engine running, the ohmmeter
should show no continuity. If the above results are
not obtained, replace the switch.
BRAKE SYSTEM WARNING LAMP
The brake warning lamp illuminates when parking
brake is applied with ignition key turned ON. The
same lamp will also illuminate should one of the two
service brake systems fail when brake pedal is ap-
plied. To test system turn ignition key ON, and ap-
ply parking brake. If lamp fails to light, inspect for a
burned out lamp, disconnected socket, a broken or
disconnected wire at switch. The lamp also lights
when the ignition switch is turned to START. To test service brake warning system, raise vehicle
on a hoist and open a wheel cylinder bleeder while a
helper depresses brake pedal and observes warning
light. If lamp fails to light, inspect for a burned out
lamp, disconnected socket, a broken or disconnected
wire at switch. If lamp is not burned out and wire continuity is
proven, replace brake warning switch in brake line
Tee fitting mounted on frame rail in engine compart-
ment below master cylinder (Fig.6 and 7). CAUTION: If wheel cylinder bleeder was opened
check master cylinder fluid level.

CHECK GAUGES WARNING LAMP TESTS
The check gauges warning lamp will illuminated
when the ignition key is turned to the ON position.
The lamp will illuminate if the engine oil pressure
drops below a safe level. The check gauge lamp will
light for high engine temperature or for low voltage. To test the system turn ignition key to the ON po-
sition. If the lamp fails to light, inspect for a broken
or disconnected wire at the oil pressure combination
sending unit, which is located at the front of the en-
gine (Fig. 13). If the wire at the connector checks
good pull connector loose from the switch terminal
and with a jumper wire ground connector to the en-
gine. With the ignition key turned to the ON posi-
tion check the warning lamp. If lamp still fails to
light, inspect for a burned lamp. If lamp still fails to
light, inspect for a burned out lamp or disconnected
socket in the cluster.
To test the switch disconnect the switch electrical
connector. Attach positive lead of an ohmmeter to
the switch terminal for the gray (GY) wire and the
negative lead to an engine ground. With the engine
off, there should be continuity in the system. Start
the engine. With the engine running, the ohmmeter
should show no continuity. If the above results are
not obtained, replace the switch.
COMBINATION OIL SENDING UNIT TEST
The combination oil sending unit has two func-
tions: (1) The normal closed circuit keeps the oil pressure
warning lamp on until there is oil pressure. (2) The sending unit provides a resistance that
varies with oil pressure. To test the normally closed oil lamp circuit, discon-
nect the locking connector and measure the resis-
tance between the switch terminal and the metal
housing. The ohmmeter should read 0 ohms. Start
the engine (Fig. 14).
If there is oil pressure, the ohmmeter should read
an open circuit. To test the sending unit, measure the resistance
between the sending unit terminal and the metal
housing. The ohmmeter should read open. Start the
engine. The ohmmeter should read between 30 to 55 ohms,
depending on engine speed, oil temperature, and oil
viscosity. If the above results are not obtained, replace the
sending unit.

to a flat wall 7.62 meters (25 ft) away from front of
headlamp lens. (2) If necessary, tape a line on the floor 7.62 meters
(25 ft) away from and parallel to the wall.
(3) From the floor up 1.27 meters (5 ft), tape a line on
the wall at the centerline of the vehicle. Sight along the
centerline of the vehicle (from rear of vehicle forward) to
verify accuracy of the line placement.
(4) Rock vehicle side-to-side three times to allow
suspension to stabilize. (5) Jounce front suspension three times by pushing
downward on front bumper and releasing. (6) Measure the distance from the center of head-
lamp lens to the floor. Transfer measurement to the
alignment screen (with tape). Use this line for up/down
adjustment reference. (7) Measure distance from the centerline of the ve-
hicle to the center of each headlamp being aligned.
Transfer measurements to screen (with tape) to each
side of vehicle centerline. Use these lines for left/right
adjustment reference.
HEADLAMP ADJUSTMENT (FIG. 3, 4, 5, 6 OR 7)
A properly aimed low beam headlamp will project the
top edge of low beam hot spot on the alignment screen
from 50 mm (2 in.) above to 50 mm (2 in.) below the
headlamp centerline. The side-to-side left edge of low
beam hot spot should be from 50 mm (2 in.) left to
50mm (2 in.) right of headlamp centerline (Fig. 1). The
preferred headlamp alignment is 0 for the
