10.2.2 Description and Operation
10.2.2.1 Description and Operation
Overview
In order to reduce the vehicle faulty rate and implement more
effective and human friendly control, electrical accessories are
controlled by a centralized control mode (BCM). BCM includes
a radio receiver and transmitter, with a frequency of 433 MHz.
External Anti-theft Feature
When the ignition key is pulled out, close the doors, rear
compartment lid (hatchback) and the engine hood. Use the
remote control to lock doors (press the lock button once), turn
signal lamps flash once. After 3 s the system enters anti-theft
mode. If the doors, rear compartment lid (hatchback), the
engine hood is not closed, when press the remote control lock
button, the turn signal lamps will flash 3 times, the anti-theft
horns will sound twice with a 2 s interval. The system will enter
the anti-theft alarm mode after 10 s (alarm loop is as following:
left, right turn signal flash, anti-theft alarm horns sound. After
30 s, the horns will stop working, the left and right turn signals
will flash 300 s). If the lock button is pressed after 10 s, the
system will not enter the anti-theft alarm mode, but it will still
enter the anti-theft mode (if there are no other external trigger
conditions, horns will not sound and turn signal lamps will not
flash). In the alarm mode, if the remote control unlock button is
pressed, it will stop the alarm loop and deactivate the anti-theft
alarm mode. If the lock button is pressed, the system will
resume its original mode. When pressing lock or unlock button,
the motor will be provided with power for 200 ms.
In the anti-theft or alarm mode, BCM will disable the starter
relay coil. At this point you can use the remote control or receive
the release signal from the ECM through the CAN bus to
deactivate the anti-theft or alarm mode (turning signal flash /
horns sound). When the remote control has no power, insert
the key into the ignition switch in the anti-theft mode, start the
engine at the same time deactivate the anti-theft or alarm
mode. After automatic re-lock, the system will re-enter the anti-
theft mode.
In the anti-theft mode, pressing the remote control "lock" and
"unlock" buttons at the same time for more than two 2 s, turn
signal lamps will flash twice and the system will enter the silent
mode. In the silent mode, the alarms do not sound. Pressing
the remote control "lock" and "unlock" buttons at the same time
for more than two 2 s, turn signal lamps will flash twice and the
system will exit the silent mode. In the anti-theft mode, pressing
the lock button twice in 500 ms, horns will sound three times,
turn signal lamps will flash three times to achieve locating the
vehicle function (in the absence of dual lock).
Door lock Control Function
When the ignition key is not inserted, press the unlock button
on the remote control, four doors will open, turn signal lamps
will flash. Press the lock button on the remote control, four
doors will lock, turn signal lamps will flash. Turn the key on the
driver side door lock to unlock position, four door will open. Turn
the key to lock position, four doors will lock. When the inside
door unlock / lock switch is unlocked, four doors will open.
When the inside switch is locked, four door will lock. Unlock the
vehicle with the remote control, in 15 s, if none of the four doors,
engine hood or the rear compartment lid (Hatchback) is
opened, the doors will automatically re-lock. If the unlock button
is pressed within 15 s, the system will time 15 s again.
When the ignition switch is at "ON" position and the vehicle
speed is greater than 20 km/h, the four doors will automatically
lock. If the speed exceeds 20 km/h again, auto-locking action
will not be repeated. Only when the ignition switch is turned
from "OFF" to the "ON" position, or any one door is opened and
re-closed, the auto-lock will be activated again.
If the key is inserted in the ignition switch at the "OFF" position
(ACC position is not detected), the door can not be locked (key
reminder function); if the driver door is open, BCM will send
warning signals to the instrument (periodically) through the
CAN bus to remind the key is not pulled out. With doors locked,
when the ignition key is pulled out, the four doors automatically
unlock. With doors unlocked, when the ignition key is pulled
out, the four doors locking device will not operate. Rear
compartment lid can be open by the remote control or by the
release switch (sedan); hatchback can be open by the remote
control or by the release switch (hatchback). At vehicle speed
up to 5 km/h, inside trunk open function will be disabled.
When the airbag deploy signals received from the CAN bus (3
or more collision signal are received), four doors will
automatically open. But this feature may not apply due to low
battery voltage or collision damage to the door lock motor
harness power supply.
Deadlock Function (If equipped) can be achieved in two ways:
– Press the remote control "lock" button twice within 500ms.
– Insert the key into the door lock, turn the key from "unlock"
to "lock" position twice within 3s.
– Turn signal lamps will flash once to confirm the above two
ways.
