mm). If clearance exceeds specification, install a new selective snap
ring to bring clearance to specification. See SNAP RING THICKNESS
SPECIFICATION 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)

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.
Cruise control system is electronically and vacuum
controlled. System components include a control unit, actuator, vacuum
pump, cruise control switch, clutch pedal position switch (M/T),
cruise indicator light, diode, Park/Neutral (P/N) switch (A/T),
stoplight switch, vehicle speed sensor and A/T control unit (if
equipped).
System has self-diagnostic capability. When self-diagnostic
mode is activated, each switch and sensor is checked for defects. When
cruise control system has been canceled without using a normal cancel
method, a trouble code will be set and stored in control unit. Trouble
codes can be retrieved to help determine which circuit is
malfunctioning.

ADJUSTMENTS
CRUISE CONTROL CABLE
Remove link protector. Loosen lock nut. Hold link "A" so that
it touches link "B". Adjust free play by turning adjusting nut until
free play is.04-.08" (1-2 mm). Tighten lock nut. See Fig. 1 or 2.

* PLEASE READ THIS FIRST *
NOTE: For further trouble shooting information, see INPUT
INSPECTION CHART. See Fig. 3. See
INSPECTION CHART FOR TROUBLE SYMPTOMS table under SYMPTOM
TESTS.
PRELIMINARY CHECKS
Inspect vacuum pump, linkage assembly, actuator, cables and
vacuum hoses. Ensure linkage and cables move smoothly. Ensure cables
do not have excessive slack or tension.
CRUISE CONTROL SWITCH FUNCTION TEST
NOTE: If vehicle speed decreases about 9 MPH less than the set
speed, set speed will be canceled. Speed will not set beyond
system limit of 124 MPH.
1) Cruise control switch is part of multifunction switch
mounted on steering column. To operate cruise control system, turn
ignition on. Turn cruise control switch to ON position. Ensure switch
indicator light comes on.
2) With cruise control switch in ON position, drive vehicle
at least 25 MPH. Press and release SET button. Vehicle speed should
stay at set speed. Instrument cluster cruise indicator light should
come on. To increase set speed, turn control switch to RESUME position
and hold until new set speed is reached.
3) To lower set speed, press SET button and hold until new
set speed is reached. To return to set speed after cancellation, move
resume switch to ON position. Vehicle speed should return to previous
setting before cancellation. Set speed should cancel when any of the
following occurs:
* Brake pedal is depressed.
* Cruise control main switch is turned to OFF position.
* Ignition switch is turned to OFF position.
* Transmission is shifted to Neutral.
SYSTEM CANCELS OR WILL NOT RESET AFTER CANCELLATION
1) Check for trouble codes. See RETRIEVING CODES under SELF-
DIAGNOSTIC SYSTEM. If no trouble codes are stored, ensure cruise
control can be set.
2) If cruise control can be set, system may have canceled due
to driving on steep hills, or a loose wiring connection. If cruise
control still cannot be set, perform SYSTEM INPUT TESTS under SYMPTOMS
TESTS.
3) If SYSTEM INPUT TESTS check okay, check vacuum pump
circuit. See CODE 11 under DIAGNOSTIC TESTS. If SYSTEM INPUT TESTS do
not check okay, see INPUT INSPECTION CHART. See Fig. 3.
SYMPTOM TESTS
SYSTEM INPUT TESTS
1) System input tests should be performed if no trouble codes
are stored when performing RETRIEVING CODES under SELF-DIAGNOSTIC
SYSTEM. System input tests cycle each cruise control switch and
sensor.

INSPECTION PROCEDURES FOR TROUBLE SHOOTING SYMPTOMS
Test No. 1
Defect in power supply system (including ground) for
diagnostic line may be possible. Probable causes are:
* Malfunction of connector.
* Malfunction of harness.
1) Check voltage between data link connector pin No. 16 and
ground. See Fig. 35. If battery voltage is present, go to next step.
If battery voltage is not present, check junction block connectors C-
81 and C-94. See Figs. 19, 21, 26 and 27. If connectors are defective,
repair as necessary. If connectors are okay and malfunction remains,
check harness between power supply and data link connector. Repair as
necessary.
2) At data link connector, measure continuity between pin No.
4 and ground and pin No. 5 and ground. If continuity is present,
replace scan tool. If continuity is not present, check data link
connector for damage or loose connections. Repair as necessary. If
connector is okay and malfunction remains, check harness between data
link connector and ground. Repair as necessary.

13. If input switch Code 26 is still displayed, go to TEST NO. 14. If
codes are no longer displayed, replace cruise control ECU.
Test No. 9
A malfunction of Vehicle Speed Sensor (VSS) or incorrect
vacuum in cruise control vacuum pump or actuator may be present.
Probable causes are:
* Malfunction of VSS.
* Malfunction of cruise control vacuum pump.
* Malfunction of actuator.
* Malfunction of cruise control ECU.
1) Check vehicle speed sensor. See VEHICLE SPEED SENSOR TEST
under COMPONENT TESTS. If speed sensor is okay, go to next step. If
speed sensor is defective, replace VSS.
2) Check cruise control vacuum pump. See VACUUM PUMP TEST
under COMPONENT TESTS. If pump is defective, replace pump. If pump is
okay, go to next step.
3) Check actuator. See ACTUATOR TEST under COMPONENT TESTS.
If actuator is defective, replace actuator. If actuator is okay,
replace cruise control ECU.
Test No. 10
A blown bulb in cruise control main switch or malfunction of
cruise control main switch is probable cause of malfunction. Replace
cruise control main switch.
Test No. 11
A malfunction of cruise control main switch, harness or
connector may exist. Probable causes are:
* Malfunction of cruise control main switch.
* Malfunction of connector.
* Malfunction of harness.
1) Check cruise control main switch. See
CRUISE CONTROL SWITCH TESTS under COMPONENT TESTS. If switch is okay,
go to next step. If switch is defective, replace cruise control main
switch.
2) Disconnect cruise control main switch connector C-01. At
harness side of connector, measure voltage between terminal No. 2 and
ground. If battery voltage is present, go to next step. If battery
voltage is not present, check joint connector C-130 and junction block
connector C-80. Repair as necessary. See Figs. 16, 18, 26 and 28. If
connectors are okay and malfunction remains, check harness between
cruise control main switch and power supply. Repair as necessary.
3) Check cruise control main switch connector C-01,
combination meter connector C-04, and joint connector C-130. Repair as
necessary. See Figs. 8, 9, 16 and 28. If connectors are okay and
malfunction remains, check harness between cruise control main switch
and dash lights rheostat. Repair as necessary.
Test No. 12
A malfunction of bulb, connector or harness may exist.
Probable causes are:
* Malfunction of bulb.
* Malfunction of connector.
* Malfunction of harness.
* Malfunction of cruise control ECU.
1) Perform cruise control indicator test. See
