11.10.2 Description and Operation

11.10.2.1 Description and Operation
Remote anti-theft system is an auxiliary vehicle alarm device.
The alarm system is triggered when there is a forcible intrusion.
The system is used in conjunction with the central locking
system. Radio frequency interference or run out of battery
power can make the system inoperative. Remote anti-theft
system allows the operation of the following components.
– Door Lock
–
Anti-theft Horn
– Turn Signal
Remote anti-theft system consists of the following main
components:
– Transmitter (Remote Control Key)
– RF Receiver (BCM)
–
Door Contact Switch
–
Hood Ajar Switch
– Rear Compartment Lid (Hatchback) Contact Switch
When the button on the transmitter is pressed, the transmitter
sends a signal to BCM. Then, BCM implements the
corresponding functions.
Remote Anti-theft
Remote anti-theft system operates independently from the
engine anti-theft system. Remote anti-theft system is designed
to sound the alarm when a door, the rear compartment lid or
the engine hood is forced open. In the alarm system, the alarm
horn will sound intermittently, while turn signal lamps will flash.
After 30 s, the horn will stop working, only turn signal lamps
flash 5 min. When all doors are closed, the alarm will continue
to sound for 30 s. After 30 s, the horn and the lamps will stop
and the doors are locked, the system returns enabled. Remote
anti-theft system will not affect the engine to start or work
properly.
Rolling Code
Remote anti-theft system uses rolling code technology. The
technology prevents any person recording the message sent
EC718/EC718RV EC715/EC715RV 10/2009
from the transmitter and use the information to get into the
vehicle. The term "Rolling Code" indicates the way the remote
anti-theft system sending and receiving signals. Transmitter
transmits signals in different order each time. Transmitter and
RF receiver synchronize according to the corresponding order.
If a programmed transmitter sending a signal that is not
consistent with the RF expected signal, the synchronization will
fail. This usually occurs when the vehicle remote control
transmitter button is pressed outside the 255 times range.
Remote Control Door Lock
– When the ignition key is not inserted, press the unlock
button on the remote control, four doors unlock, turn signal
lamps flash.
– When the ignition key is not inserted, press the lock button
on the remote control, four doors lock, turn signal lamps
flash.
Anti-theft Activated
– When the ignition key is pulled out, close all doors / rear
compartment lid / engine hood with remote control door lock
(press lock button once), turn signal lamps flash once. The
anti-theft mode will be activated in 3 s.
– Automatic locking, the anti-theft mode will be activated
automatically.
Anti-theft Activation Failure
Using the remote control lock button to lock the doors, but if
any door / rear compartment lid / engine hood is not closed
properly, turn signal lamps will flash 3 times, the anti-theft horn
will sound twice, 2 s each time, in 10 s, the anti-theft alarm will
be activated (alarm loop is as following: left and right turn signal
lamps flash, anti-theft alarm horn sound, after 30 s the horn will
stop working, only the left and right turn signal lamps flash 5
min). If in 10 s, the lock button is pressed, the anti-theft alarm
will not be activated, but the system will still be in anti-theft
mode (If no other trigger conditions, horns will not sound and
turn signal lamps will not flash). In the anti-theft alarm mode, if
the remote control unlock key is pressed, it will stop the alarm
loop, and the anti-theft status will be lifted. If the lock button is
pressed again, the system will resume its original status. As
