GENERAL INFORMATION

M14209200001USA0000010000

The wireless control module (WCM) is a system that
integrates  the  keyless  entry  function,  immobilizer
function,  and  the  TPMS  function,  and  it  has  the
following features:

｠

The  ignition  key  (transmitter)  incorporates  a  lock/
unlock switch and a panic alarm switch, and can be
operated by remote control. The ignition 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.

｠

The  ignition  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  ignition  keys
(transmitter).  Up  to  eight  ignition  keys  can  be
registered.

｠

Settings  of  the  keyless  entry  function  can  be
adjusted using a customization function.

GENERAL INFORMATION

Main components and functions

Parts name

Functional description

WCM

Controls the keyless entry functions, TPMS functions and starting of the engine
by using the following communications.

｠

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

｠

Wireless communication with the ignition key (transmitter)

｠

Wireless communication with the TPMS transmitter

Ignition key (transmitter)

The  ignition  key  (transmitter)  receives  signals  sent  from  WCM,  certifies  the
transponder ID code, calculates the encrypted code, and sends the reply data
signal to WCM. The ignition key (transmitter) also sends signals to WCM when
the lock/unlock switches on it are operated. Warning symbol and message is
additionally displayed on the Multi information display.

Combination  meter  (Multi
information display, TPMS
warning light)

Communicates with WCM via CAN. Send ignition switch status. Receives the
warning request or warning information from WCM, activates*the TPMS warning
light.

ETACS-ECU

Communicates with WCM via CAN. Receives the door lock/unlock request from
WCM, outputs the lock/unlock signal and flashes the turn signal light to inform
the driver that the doors are locked/unlocked.

ABS or ASC-ECU

Communicates with WCM via CAN. Sends the vehicle speed data.

ECM

Communication with WCM via CAN. Send atmospheric pressure data.

TPMS transmitter

Measure tire pressure directly, then send radio frequency signal to WCM.

NOTE: 

 *:

｠

Illuminates for tire pressure warning.

｠

Flashes for about 1 minute and then continuously
illuminated for TPMS malfunction warning.
