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.

Low wind volume

Blower fan normal: air pipe damaged
Cooling fan operates abnormally:
(1) Blower switch abnormal
(2) Supply voltage low
(3) Speed regulation module damaged
Wind vol-
ume normal

Compressor operates normally
(1) High and low pressure side's pressure is low
(a) Expansion valve is blocked
(b) Expansion valve opening is too small
(2) High and low pressure pipe's pressure is high
(a) High pressure pipeline malfunction, uneven flow
(b) Thermistor failure
(c) Expansion valve opening is too big
(d) Too much refrigerant oil
(e) Too much refrigerant
(f) Poor condenser heat dissipation
Note: When the speed is at 2000 r/min, cooling fan at max gear, and air tem-
perature at 30-35oC, the system's low pressure side pressure should be 147-
192 KPa, and high pressure side pressure 1373-1668 KPa
