DESCRIPTION & OPERATION
WARNING: Deactivate air bag system before performing any service
operation. See AIR BAG RESTRAINT SYSTEMS article. Do not
apply electrical power to any component on steering column
without first deactivating air bag system. Air bag may
deploy.
Instrument cluster includes speedometer, fuel gauge and
temperature gauge. Fuel gauge has a built-in voltage limiter to keep
voltage supply to gauges at 7 volts. Some models may also have an
ammeter, oil pressure gauge, tachometer, voltmeter and/or turbo boost
pressure gauge. Oil pressure gauge uses full battery voltage.
Tachometer operates by pulse feed.

TROUBLE SHOOTING
FUEL/TEMPERATURE GAUGE NOT WORKING
Check for blown fuse, faulty voltage limiter and faulty
relay. Ensure sending unit connections are clean and tight. Test
sending unit for correct operation. Tighten connections in instrument
cluster.
SPEEDOMETER NOT WORKING
On mechanical-type speedometers, ensure speedometer cable is
properly connected and correctly routed. If speedometer pointer and/or
odometer still do not work, replace speedometer cable or speedometer
assembly.
On electric-type speedometers, check for faulty vehicle speed
sensor, input/output sensors or faulty circuit. For testing, see
Page 824 of 1501
SPEEDOMETER TEST under COMPONENT TESTS. Repair or replace as
necessary.
TACHOMETER NOT WORKING
Tachometer is serviced as an assembly. If wiring harness is
okay, replace tachometer assembly.
WARNING LIGHTS NOT WORKING
Test for defective sending unit, burned-out bulb and broken
printed circuit. Ensure all connections are clean and tight.
COMPONENT TESTS
BOOST PRESSURE GAUGE (TURBO)
Resistance Test (Eclipse & 3000GT)
1) Remove instrument cluster from instrument panel. See
INSTRUMENT CLUSTER under REMOVAL & INSTALLATION. On 3000GT, remove air
distribution duct and combination gauges.
2) On all models, check resistance between boost pressure
gauge terminals on back of instrument cluster or combination gauges.
See Fig. 1 or 2. Resistance should be 68.2-83.4 ohms on Eclipse, or 72
ohms on 3000GT. If resistance is not as specified, replace gauge.

between harness connector terminal and ground. Turn ignition on, but
DO NOT start engine.
2) If test light comes on and gauge needle moves, go to GAUGE
RESISTANCE TEST. If test light does not come on and gauge needle does
not move, repair wiring to sending unit.
Gauge Resistance Test (Eclipse, Montero & 3000GT)
1) Remove instrument cluster from instrument panel. See
INSTRUMENT CLUSTER under REMOVAL & INSTALLATION. On 3000GT, remove air
distribution duct and combination gauges.
