10.2.2 Description and Operation

10.2.2.1 Description and operation

Overview

In order to reduce the failure rate of vehicles, more effective humanistic control is realized. Therefore, BCM is
integrated in electric accessories. BCM includes a RF receiver, with a frequency of 433 MHz.

External Anti-theft Function

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. When the ignition key is in the non-insertion state, press the unlock key on the remote control unit
only once within 2s (the duration is not less than 0.1s), unlock the driver-side door lock, and flicker the steering
lamp for confirmation. When the ignition key is in the non-insertion state, press the unlock key on the remote
control unit twice within 2s (the duration is not less than 0.1s), unlock the other three door locks at the same time,
and flicker the steering lamp for confirmation. When the ignition key is in the non-insertion state, press the unlock
key on the remote control unit for 1s; thus, the remote signal independently unlocks the driver-side door lock
signal (100s), and the other three door lock signals (1s). When the ignition key is in the non-insertion state, press
the lock key on the remote control unit; then lock the five doors, and flicker the steering lamp for confirmation.
When the ignition key is pulled out, close the door, lock the door through a remote control lock key (press the
lock key once), and flash the steering lamp once. After 30s, it enters into anti-theft status. When automatically
locking, the system will automatically enter the anti-theft state. 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. When the vehicle enters into an anti-theft alarm state from a non-anti-theft alarm state, the
alarm circulation is as follows: left and right flash lamps flicker and an anti-theft alarm horn beeps for 30s; then
judge again after 5s, if the alarm condition is still met after 5s, start alarm for 30s again, and there is a maximum
of 8 circulations of the anti-theft alarm triggered at every turn. During anti-theft alarm, the flicker frequency of all
turn signal lamps: 83min-1; sound frequency of horn: 3s; and ringing for 30ms.

Door lock control function

When the ignition key is in the non-insertion state, press the unlock key on the remote control unit, then lock the
four door locks and the back door lock, and flicker the steering lamp for confirmation; and press the lock key on
the remote control unit, then lock the four door locks and the back door lock, and flicker the steering lamp for
confirmation. The driver-side door key is turned to the unlocking position to unlock the four door locks and the
back door lock and turned to the lock position to lock the four locks and the back door lock. When the in-vehicle
unlocking/locking switch performs the unlocking action, the four doors and back door are unlocked. When the
switch performs the locking action, the four doors and back door are locked. After the remote control unit unlocks
for 15s, the door will be automatically relocked if any one of the four doors and the backdoor is not opened. If
repress the unlock key once within 15s, re-clock for 15s. When the ignition switch is in gear ON and the speed is
higher than 30km/h, the four door locks automatically lock. If the speed exceeds 30km/h again, do not self-lock
again. Only when the ignition switch is turned from the position OFF to the position ON or any one of door is
opened and closed again, restart the automatic locking. When the key is inserted in the position OFF of the
ignition switch (the position ACC is not detected), the door can not be locked (the function that the key is forgot
to pull out); in the state that the door lock is locked, after the ignition key is pulled out or turn to the position ACC,

1887

the four door locks and the backdoor are automatically unlocked. When the door lock is not in the locking state,
the four door locks and the back door locker are not operated after pulling out the ignition key. The back door can
be unlocked by the remote control unit or the unlocking switch. When the BCM receives an airbag opening signal,
automatically open four door locks and back door lock. However, it can not ensure to be applicable to under the
condition that the power supply of door lock control motor cannot be supplied due to battery undervoltage or
because the wire harness is damaged with collision.

Comfortable Lighting Control

–

Follower home lighting :

Under the fortification state (the body anti-theft non-alarm state), consecutively press the remote-control lock
twice within 2s, output the headlamp control signal for 60s, i.e., turn off the headlamp after delaying for 60s;
within the 60s of delaying, press the remote-control unlock key once, stop the signal output through the BCM, and
turn off the headlamp.

–

Auto-lighting function :

When the ignition switch is in position "on" and the combination switch is in position of AUTO, the position lamp
relay and headlamp relay are automatically switched on or off according to the brightness of the ambient
environment. (environment sun and sun sensor signal input)

–

Steering lamp and hazard warning lamp:

When the ignition switch is at "ON" position, turn on the left steering lamp switch. The left steering lamp will
flash at a frequency of about 85 times per minute. When the ignition switch is at "ON" position, turn on the right
steering lamp switch. The right steering lamp will flash at a frequency of about 85 times per minute.

No matter what position the ignition switch is at, press the warning switch and left and right steering lamps will
flash at the same time at a frequency of about 85 times per minute. Press the warning switch again and the
warning flash function will be canceled. During turning, if one of the steering signal lamps is (21W) damaged, the
other steering signal lamps of the same side will flash at a frequency about double of normal frequency. When the
speed is higher than 30 km/h, the key is in the position ON of the ignition switch, and the alarm switch signal is
valid, the BCM drives left front, left side and left rear steering signal lamps to flicker if the lamp switch handle is
pulled to the left lane or the left turning position. Steering lamp flashed with sound。

–

Indoor lamp Control:

The BCM controls the in-vehicle roof lam to fade in within 0.7s and fade out within 1.7s. During unlocking, the
indoor ceiling lamp will fade in turning on and will fade in turning off after 30s if there is no door opened. After
the vehicle doors are properly locked (the locking device actuates), the in-vehicle roof lamp will fade out within
1.7s. After all doors are closed and the ignition switch is closed, an indoor ceiling lamp fades out and turns off
after 30s; and after all doors are closed and the ignition switch is opened, the indoor ceiling lamp fades out and
turns off immediately. If the four doors are not closed completely from the state of being closed completely, the
BCM turns on the indoor dome lamp and shields all started functions of turning on through delaying for 30s. If the
four doors are not closed completely, the indoor dome lamp turns on for 10min through delay to turn off.

If the dome lamp turns on within 10min consecutively, the timer re-clocks when there is a signal that another door
is opened.

–

Front wiper Control:

The front wiper provides a low level signal to the BCM body control unit through a wiper switch, and the BCM
drives the front wiper motor to rotate after receiving the wiper switch driving signal; the deluxe / ultimate vehicle
is further equipped with a rain sensor; when the wiper switch is in gear Auto, the BCM provides the rainfall signal
according to the rain sensor and automatically adjusts the rotational speed of the wiper motor, thereby greatly
improving driving safety and comfort.
