Throughout this group additional important infor-
mation is presented in three ways; Notes, Cautions,
and Warnings.
NOTESare used to help describe how switches or
components operate to complete a particular circuit.
They are also used to indicate different conditions
that may appear on the vehicle. For example, an
up-to and after condition.
CAUTIONSare used to indicate information that
could prevent making an error that may damage the
vehicle.
WARNINGSprovide information to prevent per-
sonal injury and vehicle damage. Below is a list of
general warnings that should be followed any time a
vehicle is being serviced.
WARNING: ALWAYS WEAR SAFETY GLASSES FOR
EYE PROTECTION.
WARNING: USE SAFETY STANDS ANYTIME A PRO-
CEDURE REQUIRES BEING UNDER A VEHICLE.
WARNING: BE SURE THAT THE IGNITION SWITCH
ALWAYS IS IN THE OFF POSITION, UNLESS THE
PROCEDURE REQUIRES IT TO BE ON.
WARNING: SET THE PARKING BRAKE WHEN
WORKING ON ANY VEHICLE. AN AUTOMATIC
TRANSMISSION SHOULD BE IN PARK. A MANUAL
TRANSMISSION SHOULD BE IN NEUTRAL.
WARNING: OPERATE THE ENGINE ONLY IN A
WELL-VENTILATED AREA.
WARNING: KEEP AWAY FROM MOVING PARTS
WHEN THE ENGINE IS RUNNING, ESPECIALLY THE
FAN AND BELTS.
WARNING: TO PREVENT SERIOUS BURNS, AVOID
CONTACT WITH HOT PARTS SUCH AS THE RADIA-
TOR, EXHAUST MANIFOLD(S), TAIL PIPE, CATA-
LYTIC CONVERTER, AND MUFFLER.
WARNING: DO NOT ALLOW FLAME OR SPARKS
NEAR THE BATTERY. GASES ARE ALWAYS
PRESENT IN AND AROUND THE BATTERY.WARNING: ALWAYS REMOVE RINGS, WATCHES,
LOOSE HANGING JEWELRY, AND LOOSE CLOTH-
ING.

DESCRIPTION AND OPERATION
INSTRUMENT CLUSTER
The Instrument Cluster, located on the right side
of the instrument panel, provides the operator with
gauges and warning lamps relating to vehicle opera-
tion. All gauges in the standard and optional cluster
are magnetic type and logic driven.
Battery voltage for the clusters warning lamps and
gauges is provided on the G5 circuit. This circuit con-
nects from the fuse block and is protected bya5amp
fuse located in cavity 11. The cluster is powered only
when the ignition switch is in the START or RUN
position. The cluster is also powered on initial driv-
er's door opening.
Illumination lamps, internal to the cluster, receive
battery voltage on the E2 circuit from the 4 amp fuse
located in cavity 12 of the fuse block. This circuit is
HOT only when the headlamp switch is in the ON
position. Grounding for the cluster is provided on the
Z3 circuit and terminates at the instrument panel
left center support.
The M1 circuit also feeds the cluster through a 10
amp fuse in the Power Distribution Center (PDC).
This fuse is HOT at all times and also used to power
the underhood lamp, and the interior lamps. The
fuse is also lifted OPEN during vehicle shipping to
reduce battery draw.
SPEEDOMETER
The speedometer and odometer receive their infor-
mation on the G7 circuit from the Vehicle Speed Sen-
sor (VSS) on manual and 3±spd automatic
transmission applications. The G7 circuit also pro-
vides a signal to the Powertrain Control Module
(PCM).Logic internal to the instrument cluster adjusts the
position of the gauge pointer to the correct vehicle
speed using the signal on the G7 circuit.
TACHOMETER
The tachometer is connected to the Powertrain
Control Module (PCM) on the G21 circuit. It uses
solid state circuity to decode the ignition pulses
received from the PCM to adjust the gauge pointer to
the proper position.
ENGINE COOLANT TEMPERATURE GAUGE
The temperature gauge is connected to the engine
coolant temperature sensor on the G20 circuit. The
engine coolant temperature sensor for the gauge is a
combination unit. One side of the unit is used for the
Powertrain Control Module (PCM) and the other side
for the cluster. The sending unit is case grounded to
the engine.
The logic driven gauge moves in response to the
measured resistance of the engine coolant tempera-
ture sending unit.
FUEL GAUGE
The fuel level gauge is connected to the fuel pump
module on the G4 circuit. The fuel pump module con-
tains the fuel pump and a variable resistor for the
gauge. Grounding for the fuel pump module is pro-
vided on the Z2 circuit and terminates at the left
rear wheel house.
The logic driven gauge moves in response to the
measured resistance of the fuel tank sending unit.
The fuel level sensor contains a variable resistor.
As the position of the float arm on the level sensor
changes, the resistor changes the current flow
through the fuel gauge circuit. A change in current
flow alters the magnetic field in the fuel gauge which
changes the pointer position.

Downloaded from www.Manualslib.com manuals search engine ODOMETER
The speedometer and odometer receive their infor-
mation on the G7 circuit from the Vehicle Speed Sen-
sor (VSS) on vehicles equipped with the manual or
3±spd automatic transmission. This circuit also pro-
vides a signal to the Powertrain Control Module
(PCM).
Logic internal to the cluster steps the odometer at
a high rate to indicate the proper mileage.
SERVICE ENGINE SOON LAMP
The Service Engine Soon lamp illuminates when
the ignition switch is in the ON position and prior to
starting the vehicle. The lamp will turn off after the
vehicle is started.
If while the vehicle is running a problem is
detected in the engine control system the lamp is
illuminated. This is accomplished by the Powertrain
Control Module (PCM) grounding the G3 circuit.
SEAT BELT WARNING INDICATOR
The fasten seat belt indicator is used with the
warning chime to indicate to the operator to fasten
the seat belt. There is a switch located in the drivers
side B-pillar that is normally OPEN with the seat
belt buckled.
If the seat belt is not buckled the switch CLOSES
and a ground path is completed from the G10 circuit
to the Z1 circuit. This will illuminate the lamp in the
instrument cluster.
When the ignition switch is moved to the START
position the lamp will illuminate. Logic internal to
the instrument cluster determines the length of time.
LOW FUEL LAMP
The low fuel lamp is used to indicate to the opera-
tor that the fuel level is below a predetermined level.
This lamp is logic driven by the instrument cluster.
When the instrument cluster determines a low fuel
condition based on an input from the fuel tank gauge
level sending unit (circuit G4) it illuminates the
lamp.
HEADLAMP ON CHIME
The headlamp ON chime is used to indicate to the
operator that the headlamps or parking lamps are
ON when the drivers door is OPEN. If the lamps are
ON and the drivers door is opened, a ground path is
completed from the G26 circuit at the cluster,
through the headlamp switch, to the G16 circuit and
ending at the door ajar switch. The door ajar switch
is case grounded.
KEY-IN CHIME
The key-in chime is used to indicate to the opera-
tor that the key is in the ignition with the driversdoor OPEN. If the key is in the ignition and the driv-
ers door is OPEN, a ground path is completed from
the G26 circuit at the cluster, through the CLOSED
key-in switch, to the G16 circuit and terminating at
the door ajar switch which is case grounded.
CHARGE INDICATOR LAMP
The Charge Indicator lamp is used to alert the
operator that the charging system voltage has fallen
below the normal operating range. This circuit is con-
trolled by the Powertrain Control Module (PCM).
When the PCM determines a problem, it grounds the
G12 circuit.
AIRBAG WARNING LAMP
The Airbag Warning lamp is used to alert the oper-
ator of a problem with the Airbag system. The lamp
is illuminated when the Airbag Control Module
(ACM) grounds the R41 circuit. Refer to the appro-
priate section of the Service Manual or Diagnostic
Test Procedures Manual to diagnosis this system.
LOW OIL PRESSURE LAMP
The low oil pressure lamp is used to indicate to the
operator that the engine oil pressure has dropped
below a predetermined pressure. Power for the lamp
is provided on the G5 circuit which also powers the
other warning lamps.
When the oil pressure is low the normally OPEN
oil pressure switch CLOSES completing a path to
ground on circuit G6. The oil pressure switch is case
grounded to the engine block.
HIGH BEAM INDICATOR LAMP
The High Beam Indicator Lamp is used to indicate
to the operator that the high beam headlamps are
ON. Power is supplied to the cluster on the L3 cir-
cuit. Ground is provided on the Z3 circuit.
Circuit L3 connects from the headlamp dimmer
switch to the instrument cluster.
RIGHT AND LEFT TURN SIGNAL INDICATORS
These lamps are used to indicate to the operator
which turn signal is ON. Power for the lamps comes
from the turn signal switch. The L60 circuit is for the
right turn indicator, and the L61 circuit is used for
the left turn signal indicator. Ground for the circuits
is provided on the Z3 circuit.
BRAKE WARNING INDICATOR LAMP
The Brake Warning Indicator lamp is used to alert
the operator of a problem with the vehicles braking
system. The lamp illuminates when the ignition
switch is turned to START position to perform a self
check.
