Power Windows
The GWFLORID electric power window actuator consist of a motor and module. Its functions include: jam
protection, centralized control rise, soft-stop, characterized by easy control, long life, etc.
The functions of electric power window actuator
1. Jam protection
Power windows have an jam protection function when manually or automatically rising after it has been
initialized. There is no limit on the amount of jam protections. When room temperature is 25±5oC, wire
resistance 150 mΩ and 14.5 V working voltage, the jam protection force risen glass is less than 100 N. When the
window is manually or electrically rising, once it encounters a force greater than the jam protection force, the glass
will immediately stop rising and make the motor rotate in reverse. Rever\
se rotation distance is about 125 mm.
2. Centralized control rise
The central door lock controller provides four lifters with a low level signal. The power windows will close until
they are completely closed. This enables the two power window actuators to start separately, which can avoid
hitting peak currents if they start up at the same time. As long as the centralized controller's rising pin receives
the low level signal, the motor will close the window until it is comple\
tely closed.
3. Soft-stop
If the motor suffers from an impacting block when the window is rolled all the way up or all the way down, it
would shorten the power window actuator's use life. In order to avoid this, the soft-stop function must be used,
in which both manual and automatic rolling up and down should have this \
function.
(a) Soft close function:
When the window is about to get to the top, that is to say, when it's rising to the soft-stop point, the engine's
power will cut off to make the motor stop working, meanwhile the rising inertia will continue to roll the
window up to the top. The soft-stop point is about 2 mm under the top limiting position.
(b) When the window is about to lower to the bottom, that is to say, when it's lowering to the soft-stop point,
the engine's power will cut off to make it stop working, meanwhile the lowering inertia will continue to roll
the window down to the bottom. The soft-stop point is about 12 mm above the bottom limiting position.
(c) Zero position calibration: This position takes the top limiting position as the zero position. In order to
guarantee reliable and safer system operation while in use, the zero pos\
ition will need constant calibration.
Manual calibration: When the window stops at the rising soft-stop position after rising for a period,
press the rise button so it will rise to the limiting position. Zero cal\
ibration is then complete.
Automatic calibration: After the motor runs forward and reverse more than 20 times, it will undergo
zero position calibration one time. That is to say, when it completely starts or stops operating, the motor will
be blocked one time. Currently, there is no soft close or start-up function. Zero position calibration is com-
pleted when the window is completely closed to the limiting position.
4. Motor locked protection
The control module will cut off the power supply to stop the motor from working within 250 ms of the l\
ocking.
5. Motor temperature protection
When the control module is powered on, the initial temperature of the motor is set at 40oC. There are two
temperature limits for the motor's thermal protection function. If the temperature of the coil exceeds the first
temperature limit (170oC), the motor will not respond to any new operation input, but it will still complete the present
operation. If the motor's temperature exceeds the first temperature limit during its operation, it will keep working until
the temperature of the motor coil reaches the second temperature limit (190oC), then the motor will not be limited by
the second temperature's threshold while reversing, so as to guarantee the safety of the users. Once the temperature of
the motor has lowered below the temperature limit, the motor will work normally.
6. Self-diagnostic protection function
So as to guarantee the system's reliability while improving the system's average non-failure time, self-diagnostic
protection measures are used: If the power supply voltage exceeds 16 V, the control module will close the auto-
rising function.
(a) Switch contact point adhesion:
If it is detected that the switch contact point adhesion has reached up to 10 m input instructions will no
longer be received. If later the switch contact is detected to be disconnected again, it's function will return
to normal.
(b) Relay contact point adhesion:
The power window actuator is controlled by two contact point relays.
After a shutoff command is sent to one of the relays, if the system detects that this relay is still on, then
the system will choose this relay contact point for adhesion. Thereupon, the system will send out another
command to make the other electric relay switch on as well, so as to guarantee the motor's power supply is

Maintenance areas of importance
1. Initialization
Considering the system's stable and reliable operation is directly related to the state of the vehicle's door sheet
and weatherstrip, the initialization process is required at the assembly line for the overall vehicle. Continuously press
the rise button of the power window actuator to roll up the window. The window will stop rising after only rolling up
45 mm. Then, after releasing the glass switch, continuously press the rise button again. It will still only roll up 45 mm.
Basic initialization will be completed when the rise has been blocked. At this point, the system will possess all the
functions except the lowering soft-stop function. During the basic initialization rise process, there is no jam protection
function. The basic initialization is completed, and it will still have the automa\
tic lowering function.
2. Re-initialization & operating instructions are as follows
(a) This function is executable only when the following items are carried out.
• Manually correct the zero position function.
• The window rests at the mechanism dead center zero position.
(b) Within two seconds of the zero position (after the motor is blocked), release the button, then press the
button again for at least 20 s.
(c) After 20 s, the window will automatically lower about 46 mm, indicating that the characteristic curve and
zero position have been deleted.
(d) After it is deleted, the power window will only have manual function.
(e) Start initialization again.
cut off. Before sending out any new input instructions, the software will first detect whether the adhesive
contact point of the relay has been released. If it has been released, then all the operations, including the
sleep pattern, will once again be executable. If the contact point is still adhered, then only operations
going in one direction have the possibility of execution (depending on which direction the relay contact is
adhered). Then soon afterwards, activate the contact point adhesion handling funct\
ion again.
(c) Motor protection when the Hall element failed or magnetic ring damaged.
If the Hall element or magnetic ring has malfunctioned, the control module can not receive the Hall
element's signal. In this case, the control module will return to the state before basic initialization, which
means it can only rise about 45 mm at most, and it will not have the jam protection function. During
the process of a centralized control rise, re-initialization is prohibited. Once any switch is activated, the
window will stop moving.

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.
Theft deterrent controller
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.

not necessarily mean that engine start failure is due to a immobilizer system malfunction. The reasons for start-
ing engine failures are numerous, including factors like fuel, gas, fire, electricity, wires, etc. If the engine cannot
start, first check if the immobilizer system is working normally. This can be judged by looking at the flashing
theft deterrent indicator lamp which is located on the dashboard in front of the driver seat: Insert the key into the
lock cylinder and turn it to the "ON" position. If a legal key is used to start the engine, once the warning lamp is
connected to the ON end and the transponder is confirmed, the LED will remain unlit. Then when the ON end is
disconnected and the key is pulled out, the LED will shine for 0.25 s and darken for 4 s, as to act as a warning.
If an illegal key is used to start up the engine or there is something wrong with the system, the alarm indicator
lamp will shine for 0.25 s and darken for 4 s. If all is normal, then check the other parts of the engine. If abnor-
mal, first perform immobilizer system troubleshooting. A scanner can be used to judge if the immobilizer system
is working normally, but the precondition is that the scanner must be able to establish communication with the
theft deterrent controller.
1. If communication cannot be established, consider the following:
(a) Check whether the battery voltage is higher than 9 V
(b) Check whether the scanner plug is well contacted to the vehicle socket
(c) Use a multimeter to check whether the 7 pin of the OBD-II plug (diagnostic plug) is connected to the theft
deterrent controller's A7 pin
(d) Check whether the power supply of the theft deterrent controller is normal. (Use a multimeter to measure
whether the voltage of the theft deterrent controller's socket A1 pin and A2 pin is higher than 9 V)
(e) Then adopt the substitution method, which is to replace the theft deterrent controller to check if there is
anything wrong with the theft deterrent controller.
• If the failure is related to the theft deterrent controller, change it and initiate re-matching.
• If the failure has nothing to do with the theft deterrent controller, remove the electronic controller which
is connected to the alarm's K wire, such as the ABS controller, engine electrojet controller, airbag ECU
assembly, etc., as to ascertain if the present fault is caused by the wire harness connected with the theft
deterrent controller's K wire.
2. If communication can be established
Connect the scanner to the vehicle diagnostic port. Insert the key into the steering lock, and turn it to the "ON"
position, then select the scanner to check the immobilizer system's trou\
ble code.
3. Security system troubleshooting
Investigate the problem and perform troubleshooting according to the tro\
uble code on the scanner:

9000 failure, it means the replaced controller has an internal
malfunction, and the new replaced controller must be re-
matched.
