｠
All the responded keyless operation keys receive
the exterior data only.
NOTE:
The retry cycle for each door will be
performed twice when no keyless operation key
exists inside the vehicle.
NOTE:
When a keyless operation key is
detected inside the vehicle and the driver's
side door is locked, and when the door closed
last time is driver's door, KOS-ECU requests
ETACS-ECU to unlock the doors to prevent the
key from locked inside the vehicle.
｠
When all the responding keyless operation keys
have received the exterior data only during a
series of the keyless operation key certification
communications (driver's door →
front
passenger's door → liftgate), KOS-ECU moves to
Step 8.
Auto lock judgment (Keyless operation key
certification communication after interior/exterior
judgment)
8.
When the auto lock function has been selected,
KOS-ECU activates the auto lock answerback
function.
9.
KOS-ECU transmits the exterior data from the
exterior transmitter antenna assembly (driver's
side, passenger's side, liftgate).
10.
After the Step 9 is completed, KOS-ECU transmits
the interior data from the interior transmitter data
assembly (Front).
11.
After the specified time period (varies with the
number of the keyless operation keys registered in
KOS-ECU) has passed, KOS-ECU performs the
following condition judgments.
｠
When KOS-ECU receives the response from the
keyless operation keys that received the interior
data, KOS-ECU terminates the auto lock
judgment.
NOTE:
Steps 9 to 11 are performed in the
order of the driver's door → front
passenger's door → liftgate.
12.
The interior data are transmitted from the interior
transmitter assembly (front).
13.
After the specified time period (varies with the
number of the keyless operation keys registered in
KOS-ECU) has passed, KOS-ECU performs the
following condition judgments.
｠
When KOS-ECU receives the response from the
keyless operation keys that received the interior
data, KOS-ECU terminates the auto lock
judgment.
｠
When all the responded keyless operation keys
receive the exterior data only during a series of
the keyless operation key certification
communications,
KOS-ECU
continues
monitoring the keyless operation key. (Repeat
from Step 9.)
｠
When no response is received during a series of
the keyless operation key certification
communications, KOS-ECU moves to Step 14.
NOTE:
The retry cycle for each door are not
performed.
14.
KOS-ECU requests ETACS-ECU to lock the
doors. ETACS-ECU locks the doors and sends the
answerback request to KOS-ECU. By this request,
KOS-ECU sounds the outer tone alarm
answerback.
AUTO LOCK FUNCTION INHIBITION CONDITIONS
The door auto lock function is inhibited when:
｠
Any door or the liftgate is open/ajar (door switch is
ON). (including door ajar)
｠
The emergency key is in the ignition switch.
｠
The push switch in the steering lock is ON.
AUTO LOCK FUNCTION CANCELLATION
CONDITION
The auto lock function is cancelled when:
｠
No keyless operation key is detected on the outer
side of the vehicle during the keyless operation key
certification communication performed to detect if
all the doors are closed.
｠
Any of the keyless operation switches (on driver-
side door, front passenger-side door, or liftgate) is
pressed after all the doors are detected closed.
｠
All the auto lock function inhibition conditions are
met.
｠
A keyless operation key is detected inside the
vehicle.
