Function

Answer back function

•  When a locking operation is performed using the remote transmitter is in stand-by preparation mode, stand-by mode, the hazard warning lights flash once.

•  When a unlocking operation is performed using the remote transmitter is in initial mode, the hazard warning lights flash twice.

Intruder sensor cancel function

•  An intruder sensor cancel button has been installed on the remote transmitter. If the intruder sensor cancel button is on while the theft-deterrent system is stand-by preparatory mode, intruder sensor ultrasonic wave output is cut, and movement detection is stopped.

Operation (With Intruder Sensor)

Mode transition

•  The BCM switches the theft-deterrent system mode based on the ignition switch and door conditions.

Operation stop mode

•  In this mode, all theft-deterrent system operations are stopped.

•  The system changes to the operation stop mode when any of the following conditions are met.

―  Switch the ignition to ACC or ON (engine off).

Initial mode

•  This mode is the preparatory mode before changing to the stand-by mode. The system does not change directly to the alert mode from this mode.

Transition condition to the initial mode

•  The system changes from the operation stop mode to the initial mode if all of the following conditions are met.

―  Switch the ignition off

•  The system transitions from stand-by preparatory mode, stand-by mode, alert mode, and alert preparatory mode to the initial mode if the cancel conditions in each mode are met.

Alert mode

•  In this mode, the theft-deterrent siren and hazard warning lights are operated to alert the surrounding area.

•  When the alarm period (approx. 30 s) has elapsed, the system changes to the alert preparatory mode.

•  If the cancel conditions are met, the system changes to the initial mode.

―  Intrusion into vehicle is detected by intruder sensor

Transition condition to the stand-by mode

•  If there is no transition to cancel or alert mode for a period of 5 s after warning stand-by mode is established, the system switches to stand-by mode.

Cancel condition

•  If any of the following conditions are met, the alert preparatory mode is canceled and the system changes to the initial mode.

―  Unlock operation using remote transmitter

―  Switch the ignition ON (engine off), and engine start

―  Open the liftgate using the liftgate opener switch (With advanced keyless entry system)
