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.

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)\
.

Immobilizer System
Immobilizer system composition
This vehicle's engine immobilizer system consists of a theft deterrent ECU assembly, a theft deterrent coil as-
sembly, and two theft deterrent converter assemblies. The theft deterrent coil assembly is put on the head of
ignition lock cylinder, with the other end connected to the theft deterrent ECU assembly. The two theft deterrent
converter assemblies are separately installed inside the plastic handles\
of the two keys.
1. Position diagram
All the components of immobilizer system are assembled on the overall vehicle except for the theft deterrent
converter assemblies inside the keys. They achieve communication functions via the wire harness connections.
The following figure shows the position of each component in the overall\
vehicle.

Ignition lock key
Theft deterrent coil
Steering column
2. Theft deterrent controller
The theft deterrent controller assembly mainly consists of a microprocessor and peripheral components. It com-
municates with the password transmitter assembly and engine ECU. The theft deterrent controller assembly
communicates with the engine ECU via the W wire, while communicating with the theft deterrent transponder
assembly via radio frequency. The theft deterrent controller connects with the scanner via the K wire. Through
the scanner, it can initiate matching, state controlling, and malfunction diagnosti\
c on the immobilizer system.
3. Theft deterrent coil
The theft deterrent coil assembly is installed on the ignition lock cylinder, the other end of wire harness
plug is connected to the theft deterrent controller assembly. The theft deterrent coil assembly can generate
an electromagnetic field to achieve communication between the theft deterrent controller assembly and the
password transmitter assembly.
4. Transponder
The theft deterrent transponder is installed inside the key handle. It has no power supply, maintains a small size,
and long use life. It acquires electric energy and transmission signals using the stimulation of the electromagnetic
field generated by the theft deterrent coil, so as to communicate with t\
he theft deterrent controller assembly.
