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.

KEYLESS OPERATION SYSTEM (KOS)

GENERAL INFORMATION

Parts name

Functional description

Receiver antenna module

Receives the operation signals from the lock/unlock switches
and panic alarm switch on the keyless operation key, and the air
pressure signal from the TPMS transmitter, and then converts
them into data and sends them to KOS-ECU.

TPMS transmitter

Measure tire pressure directly, then send radio frequency signal
to receiver antenna module.

Combination meter (Multi information
display, TPMS warning light)

Communicates with KOS-ECU via CAN. Receives the warning
request or warning information from KOS-ECU, flashes or
activates*2the warning indicator or warnig light. Warning symbol
and message is additionally displayed on the multi information
display

ETACS-ECU

Communicates with KOS-ECU via CAN. Send ignition switch
status. Receives the door lock/unlock request from KOS-ECU,
outputs the lock/unlock signal, and flashes the turn signal light
to inform the driver that the doors are locked/unlocked.

ECM

Communicates with KOS-ECU via CAN. Permits/inhibits the
engine starting and controls the engine operation. Send
atmospheric pressure data.

ABS or ASC-ECU

Communicates with KOS-ECU via CAN. Sends the vehicle
speed data.

NOTE:

*1: When registering the keyless operation

keys, KOS-ECU numbers each key (1 to 4) in the
order they are registered (initial priority). This
priority is renewed each time the doors are
locked/unlocked and the IG knob is pressed. For
example, when only keys 1 and 3 have responded to
the signal sent from KOS-ECU, the new priority of

the keys would be 1-3-2-4. When keys 3 and 4 have
responded, then the priority of the keys becomes
3-4-1-2.

NOTE:

*2: Illuminates for tire pressure warning.

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