THEFT-DETERRENT SYSTEM


id091400003700


Outline

•  The theft-deterrent system operates the theft-deterrent horn and hazard warning lights if a door, liftgate or the hood is improperly opened.
•  An answer-back function has been adopted which allows visual verification of the theft-deterrent system operation.
•  Signal input/output of the theft-deterrent system is controlled by the rear body control module (RBCM).
•  The rear body control module (RBCM) performs theft-deterrent system fail-safe. (See REAR BODY CONTROL MODULE (RBCM).)

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


Operation (With Intruder Sensor)


Mode transition

•  The rear body control module (RBCM) switches the theft-deterrent system mode based on the ignition switch and door conditions.

•  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.
Transition condition to the stand-by preparatory mode
•  The system changes to the stand-by preparatory mode if the following condition are met.
―  A lock operation was performed using the remote transmitter lock button with all the doors, liftgate, and bonnet closed.


Stand-by preparatory mode

•  This is the mode prior to the stand-by mode.
•  If the cancel conditions are met, the system changes to the initial mode.

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.

Note
•  The liftgate will not open while the system is in the alert mode. (With power liftgate (PLG) system)
Transition condition to the alert preparatory mode
•  When the alarm period (approx. 30 s) has elapsed, the system changes to the alert preparatory mode.
•  The alarm period is not extended even if a transition condition to alert mode is met again during an alarm period.
Cancel condition
•  If any of the following conditions are met, the alert mode is canceled, and the system changes to the initial mode.
―  Unlock operation using remote transmitter
―  Switch the ignition to ON (engine off), and engine start
―  Open the liftgate using the liftgate opener switch (With advanced keyless entry system)


Alert preparatory mode

•  In the alert preparatory mode, the theft-deterrent siren and hazard warning light are not operated, however, the alarm triggers immediately if the condition is changed.
•  If the cancel conditions are met, the system changes to the initial mode.
Transition condition to alert mode
•  The system changes to the alert mode if any of the following conditions is met.
―  Forced ignition ON or ignition is switched ON without transmitter authorization
―  Door latch switch on (door is open)
―  Liftgate latch switch on (liftgate is open)
―  Bonnet latch switch off (bonnet is open)
―  Door lock-link switch UNLOCK
―  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)


Operation (Without Intruder Sensor)
