Mitsubishi Outlander XL. Manual - part 1302

GENERAL INFORMATION

M24200100001USA0000010000

NOTE: 

In this manual, F.A.S.T.-key (Free-hand

Advanced Security Transmitter) is described as
Keyless Operation System (KOS).
The  keyless  operation  system  (KOS)  enables  the
driver to unlock all the doors*and the liftgate by just
pulling the front door outside handle or operating the
liftgate lock release handle, without taking the key out
from his/her pocket or bag when he/she is carrying a
keyless operation key which has been registered in
the vehicle's KOS-ECU. KOS also allows the driver to
lock all the doors and the liftgate by pressing the lock
switch  on  the  front  door  outside  handle  or  on  the
liftgate lock release handle (door entry function), and
start  the  engine  without  using  the  conventional
mechanical key (engine start function). KOS has the
following features:

｠

The  keyless  operation  key  incorporates  the  lock
and  unlock  switches  on  it.  Like  the  conventional
keyless entry system, remote control operation can
be performed by using these switches. The keyless
operation  key  also  incorporates  an  indicator  light
that  enables  the  driver  to  check  if  the  signal  is

transmitted correctly or if the battery in the key is
discharged. (Refer to P.42B-15.)

｠

The  keyless  operation  key  incorporates  the
immobilizer function that inhibits starting the engine
by using an unauthorized key.

｠

The  incorporated  TPMS  function  monitors  the  air
pressure of all the tires.

｠

Each vehicle is provided with two keyless operation
keys, and up to four keyless operation keys can be
registered in the vehicle's KOS-ECU.

｠

The  keyless  operation  key  incorporates  an
emergency  key  with  a  transponder  to  lock/unlock
the doors and start the engine in case the battery in
the  keyless  operation  key  is  discharged  or  the
keyless operation system is not working normally.

｠

The driver can customize KOS; enabling/disabling
all the system functions, enabling the door locking/
unlocking  function  only,  or  enabling  the  engine
starting function only.

NOTE: 

When the driver’s front door outside

handle is operated, only the driver’s door is
unlocked.

Main components and functions

Parts name

Functional description

KOS-ECU

Controls  KOS  by  using  the  following  inputs/outputs  and
communications.

｠

Input from the unlock sensor and lock switch on each door,
input from the push switch on the IG knob

｠

Communications with ETACS-ECU, ECM, ABS or ASC-ECU
and combination meter via CAN

｠

Wire communication with the steering lock unit

｠

Wireless communication with the keyless operation key via the
receiver  antenna  module  and  interior/exterior  transmitter
antennas

｠

Wireless communication with the TPMS transmitter

｠

Output to the outer tone alarm

Steering  lock  (incorporates  push  switch
and steering lock unit)

The steering lock has two unlocking mechanisms; a mechanical
mechanism  that  uses  an  emergency  key  and  an  electrical
mechanism. In the electrical unlocking mechanism, the steering
lock communicates with KOS-ECU via wire, and when requested
by KOS-ECU, the steering lock unlocks for two seconds.

KEYLESS OPERATION SYSTEM (KOS)

GENERAL INFORMATION

Parts name

Functional description

Keyless  operation  key  (incorporates
emergency key)

｠

The  keyless  operation  key  receives  signals  sent  from  each
interior/exterior  transmitter  antenna,  certifies  the  keyless
operation  key  ID  code,  calculates  the  encrypted  code,  and
sends  the  reply  data  signal  to  KOS-ECU  via  the  receiver
antenna module. When the lock/unlock switch on the keyless
operation key is pressed, corresponding signal is sent to KOS-
ECU via the receiver antenna module.

｠

If two or more keyless operation keys registered in KOS-ECU
respond  at  the  same  time,  their  signals  would  interfere.  To
avoid this interference, each signal from KOS-ECU is given
the priority*1data, and the keyless operation keys respond in
accordance with this priority.

Lock switch

Driver's door

Locks all the doors and the liftgate when a driver carrying the
keyless operation key presses the lock switch on the front door
outside handle or on the liftgate lock release handle.

Front

 passenger's
