GAUGES

It is not necessary to remove instrument clus-

ter assembly from vehicle for gauge replace-
ment.

When removing gauge assemblies from cluster,

gauge must be pulled straight out, not twisted, or
damage to gauge pin may result.

MULTIPLE GAUGE MALFUNCTION

If the fuel, voltage and tachometer gauges appear

to be malfunctioning, remove the cluster assembly.
Check for good pin contact between the wire harness
and printed circuit board. If there is good contact,
check for ignition voltage at ignition cavity C of the
black connector. If there is ignition voltage, check for
continuity between the wire harness ground cavity H
of the black connector and ground. If there is conti-
nuity, replace printed circuit board.

If the temperature, oil pressure and speedometer

gauges appear to be malfunctioning remove the clus-
ter assembly. Check for a good contact between the
wire harness and the printed circuit board. If there is
good contact, check for ignition voltage at cavity J of
the red connector. If there is voltage, check for con-

tinuity at cavity H of the black connector. If there is
continuity, replace the printed circuit board.

If the temperature, fuel, voltage and speedometer

gauges appear to be malfunctioning, remove the clus-
ter assembly. Check for good pin contact between the

(2) With the ignition key ON, check for ignition

voltage at ignition pin of gauge. Check for ground at
ground pin of gauge. Refer to the individual gauge
circuit test for proper pin.

(a) If voltage at pin, replace gauge.
(b) If no voltage or ground at gauge pins, check

for ignition voltage and ground at cluster harness
connectors.

Refer to 8W, Wiring Diagrams.

(d) If there is voltage or ground, check cluster for

distorted terminals. If terminals are OK, replace
printed circuit board.

(3) When testing temperature, allow the engine to

run until the vehicle reaches a normal operating
temperature. Turn ignition OFF, and remove gauge
from cluster.

(a) Testing oil pressure gauge, engine needs to

be running.

(b) Measure and record the resistance between

sending unit pin and ground pin of the gauge in
question. Refer to Gauge Calibration.

perature and engine speed when checking temper-
ature and oil pressure gauges position. The time
between gauge position reading and sending unit
measuring should be kept to a minimum.

(d) If resistance and gauge position are not sim-

ilar, replace gauge.

(e) If OK, test resistance from the sending unit

to the cluster connector.

(f) If

resistance

reading

different,

check

printed circuit board for contact to cluster connec-
tor.

(g) If OK and contacts are not distorted, replace

printed circuit board.

(h) If everything checks out OK, refer to sending

unit test.
(4) If fuel gauge does not meet specifications, refer

to Group 14, Fuel for the test procedure.

GAUGE CALIBRATION

(1) Remove the gauge.
(2) Check for ignition voltage and ground to the

gauge.

(3) With the ignition key in the OFF position, re-

place gauge. Turn the ignition key to the ON posi-
tion. To test oil pressure gauge engine must be
running. When testing oil or temperature gauge the
engine should be at normal operating temperature.
Record the gauge position.

(4) Remove gauge and record the resistance be-

tween the sending unit pin and the gauge ground
pin. When checking gauges, it is important to have
the same engine temperature and speed when noting
gauge position. The time between gauge reading and
measuring should be kept to a minimum.

(5) The Gauge Resistance Chart (Fig. 24), is gen-

eral guidelines for checking the gauge position
against the sending unit resistance.

Because of only a few specific points of gauge posi-

tion versus sending unit resistance, a good estimate
is need when the resistance falls between gradua-
tions. Even when the resistance corresponds to grad-
uations, the gauge has a tolerance of

6 4 ohms.

Volt gauge: The calibration dot on the volt gauge

corresponds to 13 volts between the gauge ignition
and ground pins. If voltage varies from this, estimate
proper gauge position with input voltage.

ger bezels and mask/lens assembly.

(4) Check cavity H of the black connector for con-

tinuity to ground.

(5) Check for tachometer signal from the power-

train control module by connecting an AC DIGITAL
VOLTMETER to cavity B of the instrument cluster
black connector and ground. A reading of at least 1.0
volt should be present with the engine running (Fig.
26).

(a) If voltage is within specification, go to step 7.
(b) If voltage is NOT within specification, per-

form steps 6.
(6) If there is less than 1.0 volt at cavity B, check

for continuity between cavity B and pin 43 of the
powertrain control module connector.

(a) If continuity is OK, between cavity B and pin

43 of the powertrain control module connector, re-
place the powertrain control module.

(b) No continuity, check the connectors for dam-

aged pins or terminal push outs or defective wire.
(7) If all tests performed test good replace the ta-

chometer drive module.

(8) If the tachometer continues to be inoperative,

replace the tachometer assembly.

SPEEDOMETER SYSTEM

speedometer but it eliminates the cable-driven me-
chanical system. A signal is sent from a transmis-
sion-mounted

vehicle

speed

sensor

speedometer circuitry through the wiring harness.
By eliminating the speedometer cable, instrument
cluster service and removal is improved. Refer to Fig.
27 Speedometer Diagnosis Chart.
