Montero
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.

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.

CRUISE CONTROL INDICATOR TEST under COMPONENT TESTS. If cruise control
indicator is defective, replace indicator. If indicator checks okay,
go to next step.
2) If cruise control indicator illuminates when cruise
control connector C-50 terminal No. 23 is grounded at harness side,
replace cruise control ECU. If indicator does not illuminate, check
combination meter connector C-12 and cruise control ECU connector C-
50. Repair as necessary. If connectors are okay and malfunction
remains, check harness between combination meter and cruise control
ECU. Repair as necessary.
Test No. 13
1) Perform stoplight switch test. See
BRAKELIGHT/STOPLIGHT SWITCH TEST under COMPONENT TESTS. If switch is
okay, go to next step. If switch is defective, replace brakelight
switch.
2) Check cruise control ECU connector C-50, stoplight switch
connector C-55 and joint connector C-131. Repair as necessary. See
Figs. 13 , 14, 16 and 29. If connectors are okay and malfunction
remains, check harness between joint connector C-131 and cruise
control ECU.
Test No. 14 (A/T)
1) Perform park/neutral switch test. See
PARK/NEUTRAL SWITCH TEST under COMPONENT TESTS. If switch is okay, go
to next step. If switch is defective, replace switch.
2) Check starter relay. Replace if defective. If relay is
okay, check cruise control ECU connector C-50 and joint connector C-
130. Repair as necessary. See Figs. 13, 16 and 28. If connectors are
okay and malfunction remains, check harness between cruise control ECU
and power supply.
COMPONENT TESTS
ACTUATOR TEST
Remove actuator. Apply vacuum to actuator. Actuator linkage
holder should move more than 1.38" (35 mm). Actuator diaphragm should
hold vacuum. Replace actuator if actuator does not test as specified.
BRAKELIGHT/STOPLIGHT SWITCH TEST
Disconnect stoplight switch connector C-55. When brake pedal
is pressed, continuity should be present between terminals No. 2 and
3. See Fig. 14. When brake pedal is released, continuity should be
present between terminals No. 1 and 4. Replace switch if it does not
test as specified.
CLOCKSPRING TEST
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.
If clockspring fails any check, replace with a NEW
clockspring.
1) Check connectors and protective tube for damage and
deformities.
2) Visually check case for damage or deformities.
Page 324 of 1501
* PLEASE READ THIS FIRST *
NOTE: Self-diagnostics should be performed when cruise control
cancels without driver using normal cancel modes.
RETRIEVING CODES
1) Data Link Connector (DLC) is located to left of steering
column. Use analog voltmeter or scan tool for code retrieval. Follow
scan tool manufacturer's instructions.
2) Using an analog voltmeter, connect leads between cruise
control terminal and ground terminal of DLC. See Fig. 35. Count number
of deflections and pauses of voltmeter needle to determine trouble
code. Digit count is about 0.5 second per pulse and pause between
digits is about 2 seconds. Once trouble codes have been displayed, see
DIAGNOSTIC TROUBLE CODE (DTC) IDENTIFICATION table.

is 600-700 RPM. Turn engine off. Curb idle speed is automatically
controlled by Idle Air Control (IAC) system. If curb idle speed is not\
as specified, see DTC P0505 in G - TESTS W/CODES article.
4) Disconnect waterproof female connector from Brown ignition
timing check connector. See Fig. 4. Using a jumper wire, ground
ignition timing check terminal to read basic ignition timing. Using
timing light, read basic ignition timing value. See
IGNITION TIMING SPECIFICATIONS table. If basic ignition timing is
within specification, go to next step. If basic ignition timing is not
within specification, see DTC P0335 in G - TESTS W/CODES article.
5) Remove jumper wire to read actual ignition timing. Using
timing light, read actual ignition timing value. If actual ignition
timing is not within specification, see DTC P0335 in G - TESTS W/CODES
article.
All Other Models
1) Ignition timing is controlled by Powertrain Control Module
(PCM) and is not adjustable. Manufacturer provides procedure for
checking timing. On models with distributor, DO NOT attempt to adjust
ignition timing by rotating distributor.
2) Connect scan tool to Data Link Connector (DLC). DLC is
located below dash, near steering column. See Fig. 2. Install a timing
light. Start engine and allow it to idle.
3) Using scan tool, read curb idle speed (RPM). Ensure curb
idle speed is about 750 RPM. Turn engine off. Curb idle speed is
automatically controlled by Idle Air Control (IAC) system. If curb
idle speed is not as specified, see DTC P0505 in G - TESTS W/CODES
article.
CAUTION: MFI system actuator test must be cancelled or test will
continue to run for 27 minutes. Driving vehicle under this
condition may damage engine.
4) Using scan tool, select MFI SYSTEM ACTUATOR TEST, then
select item 17 (BASIC IGNITION TIMING). Read basic ignition timing
value. See IGNITION TIMING SPECIFICATIONS table. If basic ignition
timing is within specification, go to next step. If basic ignition
timing is not within specification, cancel MFI system actuator test.
See DTCS P0100 (except Mirage 1.5L), P0105, P0115 and P0335 in G -
TESTS W/CODES article.
5) Read actual ignition timing value. If actual ignition
timing is not within specification, cancel MFI system actuator test.
See DTCS P0100 (except Mirage 1.5L), P0105, P0115 and P0335 in G -
TESTS W/CODES article.

DOOR LOCKS - POWER & KEYLESS ENTRY
1998 Mitsubishi Montero
1998 ACCESSORIES & EQUIPMENT
Mitsubishi - Keyless Entry & Power Door Locks
Montero & 3000GT
DESCRIPTION & OPERATION
On 3000GT, power door locks are controlled by driver or
passenger switches which send signals to Electronic Timer Alarm
Control System (ETACS) ECU. ETACS-ECU sends appropriate signals to
individual door lock actuators through individual relays.
The following features are incorporated in power door lock
systems that have an ETACS-ECU:
* Once locked door is closed, system will unlock door if key
remains in ignition switch.
* Continuous switching between lock and unlock of door will
disable system for about one minute.
On Montero, power door lock actuator receives signal from
individual control relay that is operated by a switch incorporated in
actuator. On all models, all door locks are actuated with operation of
one lock.
Montero and 3000GT offer optional keyless entry system. Use
of a 2-button portable remote control operates door locks within a
range of 13 ft. (4 m). Dome light flashes twice when doors are locked
and illuminates for 3 seconds when doors are unlocked. If, after 30
seconds, door(s) have not been opened when unlocked with keyless entry\
system, doors will relock.
