Mitsubishi Outlander (2003+). Manual — part 428

The exclusive signal lines for transmitting the
multi-distribution data are connected as follows
between the ETACS-ECU, column switch
(incorporated inside the column-ECU), front-ECU,
power window main switch (incorporated inside the
power window-ECU), and power window sub
switches (incorporated inside the power
window-ECU) for internal communication.

Buzzer

Lamp reminder function

When the ignition key is removed and then the
driver's door is opened with turning ON the tail lamp
or the head lamp, the buzzer sounds continuously to
alert the driver that the lamp is still ON.
However, if the tail lamp or the headlamp is turned off
by the headlamp automatic-shutdown function, the
buzzer does not sound.

Central door locking

Central door locking system

When the front doors is locked (when the lock switch
turns ON after turning OFF the unlock switch in the
driver's door lock actuator), ETACS-ECU turns ON
the lock relay output for 0.25 second, and locks all
doors (including the tailgate).
When the front doors is unlocked (when the unlock
switch turns ON after turning OFF the lock switch on
the driver's door lock actuator), ETACS-ECU turns
ON the unlock relay output for 0.25 second, and
unlocks all doors (including the tailgate).

Ignition key reminder function

When the driver's door is opened with the ignition
key inserted to the ignition cylinder and the door is
locked (when the lock switch turns ON after turning
OFF the unlock switch in the driver's door lock
actuator), after approximately 0.3 second,
ETACS-ECU turns ON the unlock relay output for
0.25 second to discourage the door lock operation so
that the ignition key left in the ignition cylinder is
prevented.
If the discouraging the door lock operation fails, the
current supply will be retried. (The unlock relay
output is turned ON for 0.25 second up to five times
with one second interval.)
NOTE: The broken line in the graph indicates the
current supply retry state if the discouraging door
lock operation fails.

Impact detection door unlock function
If the vehicle crashed with the ignition switch ON or
30 seconds after turning the ignition switch to LOCK
(OFF), and the impact sensor detects an impact
greater than the specified value, the impact sensor
sends the signal to ETACS-ECU. Then, within the
0.1 second, ETACS-ECU energizes the unlock relay
for one second for releasing the door lock to prevent
passengers to kept inside the vehicle after the crash.
NOTE: The fail safe disables the operation under the
following conditions. (Diagnosis code No. 31 or 32 is
output at this time.) Turn ON the ignition switch again
after turning the ignition switch to LOCK (OFF) to
return from the fail safe state.

•

No. 31: When the ignition switch is ON, and the
sensor shows under the short circuit detect
voltage for 2.5 second

•

No. 32: When the ignition switch is ON, and the
sensor shows over the closed circuit detect
voltage for 0.4 second

Keyless entry system

Keyless entry hazard lamp answerback function
(the initial condition: with function of
lock/unlock)

The hazard lamp answerback function that allows
checking the lock/unlock state of the door easily
even in the daytime is installed. When the lock signal
from the keyless entry transmitter is received into
ETACS-ECU, all doors (including the tailgate) are
locked, and the hazard warning lamp blinks twice.
When the unlock signal is received, all doors
(including the tailgate) are unlocked, and the hazard
warning lamp blinks once.

NOTE: The answerback blink time can be adjusted
by the adjustment function.

Keyless entry room lamp answerback function

The room lamp blinks two times while locking the
door for easy checking the keyless entry function.
When the door is unlocked, the lamp lamps on for 15
seconds (100%), and turns off.

Timed locking mechanism
After unlocking the doors with the keyless entry
transmitter, if no doors are opened, if the ignition key
is not inserted or if the locking function is not
operated, the ETACS-ECU automatically locks the
doors in 30 seconds.
