The engine can be started by removing the IG knob
cap and inserting the emergency key (incorporating a
transponder ID) in KOS steering lock. In this case, the
system operates as follows:

1.

When the emergency key is turned to ON position,
the transponder (a small transmitter) incorporated
in the key transmits an ID code peculiar to each
key  (transponder  ID)  to  the  receiver  antenna
module by radio.

2.

KOS-ECU compares the transponder ID with the
ID code registered in it, and when they coincide,
KOS-ECU controls the engine ECU.

3.

The power to the transponder has been supplied
from the receiver antenna module, and therefore,
the transponder is maintenance-free. Each vehicle
is  provided  with  two  keys,  and  up  to  eight
emergency keys can be registered in the vehicle's
KOS-ECU.  More  than  one  trillion  ID  code
combinations can be registered, and parts of them
are irregularly changed whenever the ignition key

is turned ON. This feature prevents code copying,
resulting in higher security of the system.

NOTE: 

When KOS-ECU is replaced or a key is lost

or added, the ID codes of all the keys must be re-
registered as follows using scan tool:

｠

When KOS-ECU is lost, all the emergency keys and
keyless operation keys must be re-registered.

｠

When  a  key  is  lost,  all  the  emergency  keys  and
keyless operation keys other than the lost one must
be re-registered to cancel the registration of the lost
key.

｠

To add a key, all the emergency keys and keyless
operation keys to be used for the vehicle and the
additional one must be re-registered.

ENGINE STARTING FUNCTION VALID

AREA

The  engine  can  be  started  only  when  the  keyless
operation key is within the interior antenna receiving
area.

TIRE PRESSURE MONITORING SYSTEM (TPMS) FUNCTION

M24200100011USA0000010000

When the tire pressure becomes under the specified
value, the TPMS function warns the driver of that state
by illuminating the TPMS warning light.

OPERATION

｠

The signals from the TPMS receiver are received
by the KOS-ECU.

｠

KOS-ECU  processes  input  signals  from  each
TPMS transmitter as well as vehicle speed signals
from  the  ABS-ECU  or  ASC-ECU.  The  WCM  also
receives the atmospheric pressure signal from the
ECM. When the road tire pressure is low, it sends
a warning signal causing the TPMS warning light to
be  illuminated.  When  the  TPMS  has  problems,  it

sends a warning signal causing the TPMS warning
light to be flashed*.

NOTE: 

 *: Change to continuous illumination

after flashing for about 1 minute.

｠

For 3 seconds after the ignition switch is turned to
the "ON" position, KOS-ECU illuminates the TPMS
warning  light  to  check  any  breaks  in  the  TPMS
warning light circuit.

｠

By  connecting  the  scan  tool  to  the  data  link
connector,  data  stored  in  KOS-ECU  (data  of  tire
pressure and TPMS transmitter ID, the alarm status
and  warning  history,  etc.)  can  be  displayed  and
TPMS transmitter ID can be registered.

NOTE: 

If the TPMS transmitter is replaced,

register the ID codes of all the TPMS transmitters
again using the M.U.T.-III.

TPMS TRANSMITTER (TIRE PRESSURE

SENSOR)

The  TPMS  transmitter  combines  the  valve  and  tire
pressure  sensor  in  a  single  unit.  The  TPMS
transmitters are mounted inside the tires. The TPMS
transmitter measures tire pressure directly with its tire
pressure sensor and sends radio frequency signals to
KOS-ECU.

 The

 TPMS

 transmitter

 includes

acceleration  sensor  that  senses  tire  rotation.  The
KOS-ECU turns the warning light ON/OFF according
to  the  signal  from  the  acceleration  sensor  that  tells
whether the vehicle is running or stopped.

NOTE: 

Use only genuine wheels. The use of non-

genuine wheels may cause the improper installation

of the TPMS transmitters, possibly resulting in
air leakage and damage to the TPMS transmitter.

If the KOS failed, operated improperly, TPMS fails or
the tire pressure is low, KOS-ECU warns the driver of
this by setting off the outer tone alarm and the keyless

operation warning indicator, TPMS warning indicator,
or TPMS warning light on the multi information display
in the combination meter.
