Repair or replace components as necessary. If no problems exist, go to
next step.
2) Ground fan motor 3-pin connector terminal No. 3 (Black
wire). Using a fused jumper wire, connect battery voltage to 3-pin
connector terminal No. 2 (Blue wire). See WIRING DIAGRAMS. Fan motor
should operate with no abnormal noises or interferences. Repair or
replace components as necessary.
Engine Coolant Temperature (ECT) Sensor
Remove ECT sensor from vehicle. Suspend sensor in water so
that sensor does not touch container. Slowly heat water. Using an
ohmmeter, check sensor continuity as temperature increases. Replace
ECT sensor if resistance is not as specified. See
ENGINE COOLANT TEMPERATURE SENSOR RESISTANCE table.

Electric Cooling Fan Relay (Diamante, Eclipse, Galant &
Mirage)
1) Remove radiator fan motor relay from relay box located at
right side of engine compartment. Check for continuity between relay
terminals No. 1 and 3. If continuity exists, go to next step. If
continuity does not exist, replace cooling fan relay. See Fig. 8.
2) Using a fused jumper wire, connect battery voltage to
cooling fan relay terminal No. 1. Using another jumper wire, connect
cooling fan relay terminal No. 3 to battery ground. With cooling fan
relay energized, there should be continuity between cooling fan relay
terminals No. 4 and 5. With cooling fan relay not energized, there
should be no continuity between terminals No. 4 and 5. If continuity
does not exist as specified, replace cooling fan relay. See Fig. 8.
Electric Cooling Fan Relay (Montero, Montero Sport & 3000GT)
1)Remove relay from relay box in engine compartment relay
box. Check for continuity between relay terminals No. 2 and 4. If
continuity exists, go to next step. If continuity does not exist,
replace cooling fan relay. See Fig. 9.
2) Using a fused jumper wire, connect battery voltage to

1) If only the radiator fan does not operate, check fusible
link No. 6 located in engine compartment relay box. If only the
condenser fan does not operate, check dedicated fuse No. 16 (20-amp)
located in engine compartment relay box. See WIRING DIAGRAMS. Repair
as necessary.
2) If radiator fan and condenser fan operate in all speeds
except low, check appropriate low speed relay. See COMPONENT TESTS.
See WIRING DIAGRAMS . If low speed relay is okay, check PCM. See
appropriate G - TESTS W/CODES article in ENGINE PERFORMANCE.

Remove relay from engine compartment fuse/relay box. Using an
ohmmeter, check relay continuity. With battery voltage not supplied to
relay, continuity should exist between terminals No. 1 and 3. With
positive battery terminal connected to relay terminal No. 1 and
negative battery terminal connected to relay terminal No. 3,
continuity should exist between terminals No. 4 and 5. See Fig. 33. If
continuity is not as specified, replace relay.

Remove hazard light switch from instrument panel. Disconnect
switch connector. Using an ohmmeter, check switch continuity. With
switch in OFF position, continuity should exist between terminals No.
5 and 7, and between terminals No. 9 and 10. With switch in ON
position, continuity should exist between terminals No. 1, 2 and 4,
between terminals No. 5 and 6, and between terminals No. 9 and 10. See

BENCH TESTING
* PLEASE READ THIS FIRST *
CAUTION: Perform tests in less than 10 seconds to prevent damage to
coil.
NO-LOAD TEST
1) Install starter in soft-jawed vise. Connect starter in
series with a fully-charged 12-volt battery. Connect a 100-amp ammeter
and carbon pile rheostat in series with positive battery post and
starter motor terminal. See Fig. 2.
2) Install voltmeter across starter motor. Adjust carbon pile
rheostat to full resistance. Connect cable from starter motor body to
negative battery terminal. Adjust carbon pile rheostat to proper test
voltage. Ensure maximum amperage is as specified and starter rotates
