Comfortable Lighting Control
1. Courtesy Lights:
If the ignition key is pulled out less than 10 min, turn the light
switch from OFF to ON position within 2 s (park lamp,
headlamp, or auto-headlamp) and then turn it back to OFF
position, the courtesy headlamp will be activated. At this time,
the headlamps light up will be delayed by 30 s. When this
function is activated, if a door is opened, the headlamps will
light up for 180 s, which are any door (including the trunk)
opening timing. After all doors closed, it will re-time 30 s.
2. Automatic Lighting Function:
When the ignition switch is at "ON" position, and the headlamp
switch in at AUTO position, park lamp relay and the headlamp
relay automatically connect or disconnect in accordance with
the surrounding environment brightness. (Need signal input
from ambient and sun light sensor)
3. Turn Signal and Hazard Lamps:
When the ignition switch is at "ON" position, turn on the left turn
signal switch. The left turn signal lamp will flash at a frequency
of about 85 times per minute. When the ignition switch is at
"ON" position, turn on the right turn signal switch. The right turn
signal lamp will flash at a frequency of about 85 times per
minute. No matter what position the ignition switch is at, press
the hazard lamp button and left and right turn signals will flash
at the same time at a frequency of about 85 times per minute.
Press the hazard lamp button again and the warning flashing
will be disabled. In the turning status, if one of the turning lamps
(21 W) is damaged, the other turn signal lamp will flash at about
double the frequency.
4. Interior Lighting Control:
BCM controls the dome lamp fade in light in about 0.7 s and
fade out light in about 1.7 s. When unlocking, the dome lamp
will fade in light, if there is no door open action, the dome lamp
will fade out after 15 s. When doors are locked (lock device
operated), the dome lamp will fade out within 1.7 s. When all
doors are closed and the ignition switch is switched off, dome
lamp will fade out after 15 s; with all doors closed, if the ignition
switch is switched on, dome lamp will fade out immediately.
Any door opens, dome lamp will fade in light and keep lit, until
the door closes and it will fade out after 1.7 s, turned off
because of energy saving feature (the ignition switch is at
"OFF" position, the energy saving function will be activated
after 20 min).
5. Emergency Brake Warning Lamp:
If the vehicle speed (BCM receives the signal through the CAN
bus.) is rapidly decreased due to emergency braking, all the
turn signal lamps will be activated and flashing; if the vehicle
speed stops rapid decreasing, hazard lamp flashing will be
disabled.
6. Daytime Running Light (If equipped):
When the engine is running, the daytime running light should
be automatically turned on. The daytime running light should
be automatically turned off when the headlamps are turned on,
but remain on when the headlamps flash briefly. (High beam
lamps being turned on for less than 700 ms is regarded as
intermittent flashing warning).
Rear Wiper / Washer Control
Turn the rear wiper/washer switch to the continuous operation
position, the rear wiper relay will be activated and the rear wiper
will work continuously. Turn the rear wiper/washer switch to the
intermittent operation position, the rear wiper relay will be
activated for about 600 ms every 5 s, and the rear wiper will
work in intermittent mode. If the washer switch is pressed, the
rear wiper relay will be activated for about 4 s. If the switch is
pressed and held, BCM will be informed that the switch has
been pressed only once. If the reverse gear is selected and the
wiper switch is placed at low speed position, the rear wiper
relay will be activated by 10 s delay. The rear wipers wipe once
every 10 s.
When the voltage signal is received from the CAN bus, if the
battery voltage is greater than 10.7V, and the ignition switch is
at "ON" position, the rear defroster and heated rear window
start to work; when the detected voltage is less than 10.3 V, the
rear defroster and heated mirrors do not work.
The rear defrost and rear window heating switch is a push
button switch. When the switch is pressed, the rear defroster
and the rear window heater will start working for about 12 min;
If the switch is pressed again during the rear defroster and the
rear window heater working period, they will stop working.
Pressed again, the rear defroster and the rear window heater
will work the remaining time of the first 12 min (cumulative run
12 min). There should be a time parameter (about 36 min) to
reset the first timer. After 36 min, the pre-heating time will not
be cumulated as the next working time. In the low voltage
status, the rear defroster / heater do not work, but the previous
timer (12 min) will not be interrupted and still cumulated for the
next cycle.
Rear defroster / rear window heater working signal will be sent
to ECM through CAN.
