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.

TRANSMITTER PROGRAMMING
NOTE: Transmitter programming should be performed only after
verifying that door lock operates normally using key.
NOTE: Ensure ignition is off when connecting or disconnecting scan
tool.
Using Scan Tool (Montero & 3000GT)
1) Connect scan tool to DLC. Close all doors. Turn ignition
switch to ACC position, then to OFF position. Press desired
transmitter switches (secret code), then press twice within 10 seconds\
to register code.
2) Lock and unlock door once. If there are 2 transmitters,
program the first, then the second transmitter using the same
procedure within one minute. After completing the second programming,
lock and unlock door once.
3) Programming mode is finalized when programming of second
transmitter secret code is complete, one minute after setting secret
code, when scan tool is disconnected, when ignition is turned on or
when any door is opened.
Without Scan Tool (Montero)
1) Move code registration switch on RKE control unit to SET I
position. Press the LOCK or UNLOCK button on transmitter. Move code
registration switch on control unit to FIX position.
2) Confirm that keyless entry system operates normally. If
system does not operate normally, repeat step 1). If 2 transmitters
are used, register code on SET II position on RKE control unit and set
in same manner as the first transmitter.
TROUBLE SHOOTING
POWER DOOR LOCK INOPERATIVE
Operate door lock(s) with ignition switch in OFF position. If\
door lock(s) do not operate, check for following possible causes:
* Burned fuse, circuit breaker or fusible link caused by short
to body ground.
* Wire connector, or pin inside connector, disengaged at any
connector or component in system.
* Defective ETACS-ECU (if equipped).
* Defective door lock switch, relay or actuator.
* Subfreezing weather conditions, mechanical failure, or
corroded or misaligned assemblies.
KEY REMINDER SYSTEM INOPERATIVE (ETACS-ECU CONTROLLED SYSTEM)
With key inserted in ignition switch, lock driver's or
passenger's door and close door. If door locks do not unlock, check
for following possible causes:
* Defective key reminder switch or no input signal to
ETACS-ECU.
* Defective front door switch or no input signal to ETACS-ECU.
* Defective vehicle speed sensor or no input signal to
ETACS-ECU.

KEYLESS ENTRY CONTROL UNIT
Page 405 of 1501
NOTE: Testing information for RKE control unit is not available
from manufacturer at time of publication. See
PIN VOLTAGE TESTS .
NOTE: If after all testing procedures are completed, system is not
functioning properly, replace unit with a known-good keyless
entry control unit and retest.
POWER DOOR LOCK CONTROL UNIT
Montero (W/O Remote Keyless Entry)
1) Remove power door lock control unit. See
COMPONENT LOCATIONS . Apply battery voltage to control unit terminal
No. 8 (Red/Yellow wire). See WIRING DIAGRAMS.
2) Jumper control unit terminals No. 4 (Black wire), No. 5
(Blue/White wire), and No. 7 (Black/Yellow wire) to battery negative\
terminal. Connect an analog voltmeter between ground and terminal No.
3 (Blue/Red wire). Set voltmeter to DC volts.
3) Remove jumper from control unit terminal No. 5 or 7.
Voltmeter needle should deflect.
4) Jumper control unit terminals No. 4 (Black wire) and No. \
5
(Blue/White wire) to ground. Connect voltmeter between ground and
terminal No. 3 (Blue/Red wire). Jumper control unit terminal No. 7
(Black/Yellow wire) to ground. Voltmeter needle should deflect.
5) Jumper control unit terminal No. 4 (Black wire) to ground\
.
Connect voltmeter between ground and control unit terminal No. 3
(Blue/Red wire). Jumper control unit terminal No. 7 (Black/Yellow
wire) to ground. Voltmeter needle should not deflect.
6) Check if voltage is present between battery ground and
control unit terminals No. 2 (Black/Blue wire) and No. 6 (Black/Red
wire). Battery voltage should be present. If circuits do not test as
specified, replace door lock control unit.
BACK DOOR (LIFTGATE) LOCK ACTUATOR
Montero
Access door lock actuator. See DOOR LOCK ACTUATOR R & I under
REMOVAL & INSTALLATION. Disconnect back door actuator harness
connector. Remove actuator if needed. Connect positive lead of 12-volt
power source to actuator connector. Actuator should operate when
