Calibration Test
Adjust tire pressure to standard value. Using a calibrated,
reliable speedometer tester, compare reading of vehicle speedometer to
speedometer tester. See SPEEDOMETER ALLOWABLE VARIATION table. Replace
speedometer if necessary.

TACHOMETER
NOTE: DO NOT reverse polarity when installing tachometer, as diode
and transistor may be damaged.
Calibration Test
Connect a calibrated, reliable tach-dwell meter to vehicle
ignition system. Operate engine at various speeds (RPM). See
TACHOMETER ALLOWABLE VARIATION table. If comparison between tach-dwell
meter and vehicle tachometer readings do not fall in the standard
range of permissible variation, replace vehicle tachometer.

TEMPERATURE GAUGE
CAUTION: DO NOT connect sender wire directly to ground during test.
Circuit Test
Disconnect temperature sender wire from sending unit. Connect
a 12-volt, 3.4-watt test bulb between connector terminal and ground.
Turn ignition switch to ON position. If test bulb flashes and
temperature gauge needle moves, go to SENSOR RESISTANCE TEST. If test
light does not flash and gauge needle does not move, repair wiring to
sending unit.
Sensor Resistance Test
Remove thermosensor (sending unit) from engine block. Place
sending unit in hot water of 158
F (70C) temperature. Check sensor
resistance with an ohmmeter. Thermosensor resistance should be 90-117
ohms at 158
F (70C). If thermosensor resistance in okay, go to GAUGE
RESISTANCE TEST. Replace thermosensor if resistance is not as
specified.
Gauge Resistance Test
Remove instrument cluster from instrument panel. See
INSTRUMENT CLUSTER under REMOVAL & INSTALLATION. Measure resistance
between temperature gauge terminals at rear of cluster or combination

CAUTIONS & WARNINGS
SUPPLEMENTAL RESTRAINT SYSTEM (SRS) AIR BAG SYSTEM
NOTE: See the AIR BAG RESTRAINT SYSTEM article in the
ACCESSORIES/SAFETY EQUIPMENT Section.
The SRS has no user-servicable parts. Always have servicing
done by an authorized dealer.
When performing maintenance on air bag equipped vehicles
always observe proper safety precautions.
WARNING: To avoid injury from accidental air bag deployment, read and
carefully follow all warnings and service precautions. See
appropriate AIR BAG RESTRAINT SYSTEM article in the
ACCESSORIES/SAFETY EQUIPMENT section.
CAUTION: Disconnect negative battery cable before servicing any air
bag system, steering column or passenger side dash
component. After any repair, turn ignition key to the ON
position from passenger's side of vehicle in case of
accidental air bag inflation
ANTI-LOCK BRAKE SYSTEM (ABS)
CAUTION: Never mix different diameter tires. On loose or uneven
surfaces, the ABS system may require longer stopping
distances than conventional brake systems. Exercise caution
when removing mud or snow from the wheels so as not to
damage the ABS wiring or speed sensors.
BATTERY WARNING
WARNING: When battery is disconnected, vehicles equipped with
computers may lose memory data. When battery power is
restored, driveability problems may exist on some vehicles.
These vehicles may require a relearn procedure. See
appropriate COMPUTER RELEARN PROCEDURES article in the
GENERAL INFORMATION section below.
REPLACING BLOWN FUSES
Before replacing a blown fuse, remove ignition key, turn off
all lights and accessories to avoid damaging the electrical system. Be
sure to use fuse with the correct indicated amperage rating. The use
of an incorrect amperage rating fuse may result in a dangerous
electrical system overload.
BRAKE PAD WEAR INDICATOR
Indicator will cause a squealing or scraping noise, warning
that brake pads need replacement.
