11.9.2 Description and operation

11.9.2.1 Description and operation

The remote control anti-theft system is an auxiliary vehicle alarm device. The alarm system is
triggered when the vehicle forces to invade. The system is matched with a remote control central
lock system. The system may be invalid due to the radio frequency interference or the exhaust of
the electric quantity of the battery. The remote control anti-theft system admits the operation of
the following parts.

– Door

lock

– Anti-theft

horn

–

Light up steering lamp

The remote control anti-theft system comprises the following main parts:

– Sender(remote

key)

–

Radio frequency reception, (BCM)

–

Door contact switch

When pressing down a button on an emitter, the emitter sends out a signal to the BCM. Then,
BCM executes the corresponding function.

Remote control anti-theft

The remote control anti-theft system is operated independent from the engine anti-theft system.
The design of the remote control anti-theft system is to give the alarm when somebody forces to
open the door. Under the alarm system, the anti-theft horn will emit an intermittent alarm sound
and the steering signal lamp also flickers at the same time. After 30 seconds , the horn stops and
only left and right flashlights flash for 5 minutes . After all doors are closed, the alarm buzzer will
continually beep for 30s. After 30s, horn and lamp stop warning, and vehicle doors are locked, and
the system will return to activation status. The remote control anti-theft system does not affect

Affect the starting or normal operation of the engine.

Rolling code

The remote control anti-theft system uses a rolling code technology. The technology can prevent
anyone fro recording the information sent from the transmitter and entering the vehicle by
adopting the information. The term of "rolling code" refers to the manner of transmitting and
receiving signal through a remote alarm system. The emitter transmits signal in different order at
every turn. The emitter and the radio frequency receiver are synchronized in corresponding
sequence. If the signal sent out by a programmed emitter is inconsistent with the expected
sequence of the radio frequency receiver, the emitter loses synchronization. This usually happens

2469

after the emitter button is pressed for 255 times outside the remote control range of the vehicle.

Remote control door lock

–

Non -insert status of ignition key .pressed unlock key of remote controller for one in the 2s
(time of duration is less than 0.1s) driver's side door lock is "ON". Turning lamp flashing
confirmed

When ignition switch is not in connection status, after pressing the unlock key on remote
controller within 2s two times (lasting time should not less than 0.1s), the other three door locks
will be open at the same time, and the turning lamp will flash to confirm it.

When ignition switch is not in connection status, after pressing the unlock key on remote
controller for 1s, the remote controlled signal will separately release the signal of driver’s side
door (100s), and then release the signal of other three door locks.

Entering anti-theft

When ignition key is pulled out and the door is closed, use remote lock key to lock the door (press
the lock key once), and the turning lamp will flash once time. After 30s, it enters into anti-theft
status.

–

System automated access anti-theft status.

Entering anti-theft failure

When the door is locked by a remote control unit lock key, the steering lamp flickers three times
and the anti-theft horn sounds three times if the door/backdoor is are not closed well; then, enter
into the anti-theft alarm state after 10s (the alarm circulation is as follows: the flickering frequency
of the left and right flash lamps is consistent with the sound frequency of the anti-theft alarm horn;
then the horn stops sounding after 30s, and only the left and right flash lamps flicker for 5min. If
not entering the anti-theft alarm state by re-pressing the lock key within 10s, but entering anti-theft
alarm distribution (however, the horn does not make a sound unless other ambient condition
triggers, and the steering lamp also does not flicker). In the anti-theft alarm mode, if the remote
unlock button is pressed again, it will stop the alarm cycle, and the anti-theft alarm arrangement
status will be deactivated. Repress the lock key to restore the initial state. It is shown in figure
below:
