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.

WARNINGS/ALARMS

M24200100006USA0000010000

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.
