ECU MITSUBISHI MONTERO 1998 Manual PDF

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.
INPUT SIGNAL

Scan Tool Method (3000GT)
Turn ignition off. Connect scan tool to DLC. Follow scan tool
manufacturer's instructions. Turn ignition on. Perform ON/OFF
operation of each door lock or power window switch. If scan tool
buzzer sounds once, ECU input signal to corresponding switch circuit
is normal.
Voltmeter Method (3000GT)
Using Diagnostic Trouble Code Check Harness (MB991529),
connect harness to DLC terminals No. 4 and 5. Connect voltmeter to
harness. Turn ignition on. Perform ON/OFF operation of each door lock
or power window switch. If voltmeter pointer moves once, ECU input
signal from corresponding switch circuit is normal.
COMPONENT TESTS
* PLEASE READ THIS FIRST *
NOTE: If after all testing procedures are completed, system is not
functioning properly, substitute with a known-good ETACS-ECU
and retest.
DOOR LOCK ACTUATOR
Left Front Door (Montero & 3000GT)
1) Access left front door lock actuator. See
DOOR LOCK ACTUATOR R & I under REMOVAL & INSTALLATION. Disconnect
harness connector. Set actuator in LOCK position. Connect positive
lead of 12-volt power source to actuator terminal No. 1 (Blue/Red
wire) on Montero or terminal No. 3 (Blue/Red wire) on 3000GT. See
WIRING DIAGRAMS . Actuator should move to UNLOCK position when terminal
No. 3 (White/Black wire) on Montero or terminal No. 1 (Blue/Black
wire) on 3000GT is connected to ground.
2) With actuator set in UNLOCK position, connect positive
lead of 12-volt power source to actuator terminal No. 3 (White/Black
wire) on Montero or terminal No. 1 (Blue/Black wire) on 3000GT. See
WIRING DIAGRAMS . Actuator should move to LOCK position when terminal
No. 1 (Blue/Red wire) on Montero or terminal No. 3 (Blue/Red wire) o\
n
3000GT is connected to ground.
3) On 3000GT, check for continuity between actuator terminals
No. 2 (Brown/Yellow wire) and No. 4 (Black wire). See WIRING DIAGRAMS.
Continuity should be present with actuator set in UNLOCK position.
Continuity should not be present with actuator set to LOCK position.
Right Front Door (Montero & 3000GT)
1) Access right front door lock actuator. See
DOOR LOCK ACTUATOR R & I under REMOVAL & INSTALLATION. Disconnect
harness connector. Set actuator in LOCK position. Connect positive
lead of 12-volt power source to actuator terminal No. 3 (Blue/Red
wire) on Montero or terminal No. 1 (Blue/Red wire) on 3000GT. See
WIRING DIAGRAMS . Actuator should move to UNLOCK position when terminal
No. 1 (White/Black wire) on Montero or terminal No. 3 (Blue/Black
wire) on 3000GT is connected to ground.
2) With actuator set in UNLOCK position, connect positive
lead of 12-volt power source to actuator terminal No. 1 (White/Black
wire) on Montero or terminal No. 3 (Blue/Black wire) on 3000GT. See
WIRING DIAGRAMS . Actuator should move to LOCK position when terminal
No. 3 (Blue/Red wire) on Montero or terminal No. 1 (Blue/Red wire) o\
n
3000GT is connected to ground.
3) On 3000GT, check for continuity between actuator terminals
No. 2 (Brown wire) and No. 4 (Black wire). See WIRING DIAGRAMS.
Continuity should be present with actuator set in UNLOCK position.
