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.
