Reverse Sensor
Reverse sensor operation (ultrasonic wave distance-measurement)
Sound is a kind of wave. Sound frequency that can be heard by human beings range from 20 Hz to 20 KHz.
Those that exceed 20 KHz are called ultrasonic waves. Since an ultrasonic wave is also a kind of sound, its
velocity in the air also equals the sound velocity of 340 m/s. Part of the ultrasonic wave will rebound when it
encounters an obstacle. So the distance between the sound source and the obstacle can be calculated according
to the sonic speed and the time difference between the emission of sound and the receipt of sound.
Reverse sensor system composition
This system is composed of a reverse sensor head unit (ECU), four sensors (SENSOR) and an external buzzer.

Functional description and display program
1. This system will be activated within the first second after engaging the reverse gear. There will be two
beeps indicating the system is working properly.
2. After the self-check, it will start its normal detection mode. The relationship between the obstacle
distance and the alarm frequency is as follows:
A Zone: When it is a long sounding alarm, the obstacle is within the distance of (0-40±4) cm.
B Zone: When the alarm frequency is an 8 Hz continuous sound, the obstacle is within the distance of
(40±4-90±4) cm.
C Zone: When the alarm frequency is a 4 Hz intermittent sound, the obstacle is within the distance of (90±4-
150±4) cm.
Areas of importance
1. When placed near a car equipped with the same system or a similar system (having been activated)
offered by other suppliers, though this system may receive interference, i\
t can still operate normally.
2. When the relative rate of travel between the obstacle and the car is lower than 1 m/s, this system will
operate as normal. When reverse speed is accelerated, the sensing accuracy of the reverse system
may decrease. A low speed of 6 km/h is suggested.
3. When it is a long sounding alarm, please stop the car at once, because there may be an obstacle
within 40cm.
4. The inductor precision level is high. It will be very difficult to return it to normal after opening the inner
portion.
5. The reflected signal may not be received due to the location, angle, size, or material of the object.
Furthermore, the reflected signal in a complex environment may not be ac\
curate.
System malfunction causes and solutions
1. A lack of power or a low supply voltage may lead to the abnormal operation of the reverse sensor
system. Under such circumstances, check whether the supply battery voltage is normal, or whether
the ignition switch connector and other connections are accurately place\
d.
2. If the power supply is on, irregular system operation may be caused by the incorrect position of the
socket. Under such circumstances, correctly re-place all the sockets.
3. A long sounding alarm from the buzzer may be caused by the inductor coming off, incorrect installa-
tion, damage to the inductor, or detecting the car or ground. Under such circumstances, please repair
or replace the sensor.
4. Incorrect indication of an obstacle's distance may be caused by abnormal battery voltage, inaccurate
socket positioning, or inductor connection damage. At this time, check whether the battery voltage
is normal, and whether the inductor connection is connected to the exhaust pipe and muffler. It is
suggested that the system be turned off and all the sockets be correctly placed.

Combination Meter
If something is wrong with the meter, check the relevant component and circuit according to the connector defi-
nition. If the failure still cannot be eliminated, check whether the instrument itself has malfunctioned in the fur-
ther steps. The following diagram shows the view of the meter connector and its numb\

Central Door Lock
1. Lock
After closing the door (when unlocked), press the LOCK button once on the remote controller, the car lamp
flashs once, and all five doors will be locked.
2. Unlock
When locked, press the UNLOCK button once on the remote controller, the car lamp will flash twice, and all
four front doors will be unlocked.
3. Vehicle pager function
Press the LOCK button once on the remote controller while all the doors are closed and locked. The car lamp
will then flash ten times. Press the UNLOCK button to exit the vehicle pager function. If the doors are not well
closed and locked, then press the LOCK button once on the remote controller, in which case the lamps will not
flash.
4. Auto-defense function
While locked, press the UNLOCK button on the remote controller. If the doors are not open, it will automatically
lock after 30s.
5. Auto-close window function (jam protection window regulator)
(a) Pull the key out and make sure all the doors are closed, then press the LOCK button on remote controller,
the side windows will close after 1 second of negative output.
(b) After pulling out the key, the sunroof will close after 60 seconds of negative output (reserve)\
.
6. Remote controller function suspension
When the key is inserted into the ignition lock, the remote controller will not work, but the head unit will work
as normal.
7. Manual lock and unlock
Locking or unlocking can be manually controlled.
8. Deleting or registering remote learning functions of the remote controll\
er
Step one: Under normal circumstances, open the front left door (do not close). Insert the key into the ignition
lock, within five seconds, switch it ON and LOCK five times and stop it at the ON position the fifth time. The
buzzer will sound once and the light will flash once. It is now in the l\
earning state.
Step two: Press any key on the remote controller within 10 seconds, the buzzer will sound twice, and the light
will flash twice. This is the first learning state. Press any key on another remote controller, it will sound twice,
and the light will flash twice. Second learning successful (A total of four remote controllers can learn).
Step three: After successful learning, pull the key out (ON-LOCK) to exit the learning state. If no key is pressed
within 10 seconds, the system will exit from the learning state automati\
cally.
9. Dome lamp delay function
(a) Open the door and then close it, the lamp will light for 10 seconds. If the key is inserted into the ignition
lock head or door lock within these 10 seconds, the lamp will gradually \
extinguish.
(b) When the key is pulled out of the ignition lock head, the dome lamp will turn on. If the key is inserted into
it again or the door is locked, the dome lamp will turn off gradually after one minute.
10. Alert function
(a) If the key is inserted (low) and is not at the ON gear (high), when the front left door is opened (low), the
buzzer will emit an intermittent chirp.
(b) If the key is not inserted (low) and the lamplet is on (high), when the front left door is open (low), the
buzzer will emit a long chirp.
11. Trunk door independent open function
(a) After pressing the trunk lock striker of the remote controller and turning the trunk door switch on, the trunk
door actuator will open (14th pin will output positive voltage), and then the trunk door can be opened. If
the trunk door does not open after pressing the trunk lock striker for 60 seconds and then switching the
trunk door on, then the trunk door actuator is unable to open (14th pin\
is not outputting positive voltage).
(b) When the trunk lock striker of the remote controller is not pressed or the trunk door is not opened after
pressing the button for 60 seconds, the trunk door actuator cannot be opened after switching the trunk door
on (14th pin is not outputting positive voltage).
