2006 GREAT WALL HOVER Service Repair Manual

Controller of the Central Door Lock
1. Positive pole of the power supply (12V) is connected to the positive pole of car’s battery through a 15A fuse; when the
engine is started, the voltage is not less than 10V.
2. Output of the central door lock. The unlock cable connected to the executor of the central door lock is usuall
y grounded
through the normally-closed contact of the internal relay; when the door is unlocked by the remote controller or unlocked
manually, the public contact of the relay will get through with the normally-open contact, realizing an output of 12V
voltage.
3. Out
put of the central door lock. The lock cable connected to the executor of the central door lock is usually grounded
through the normally-closed contact of the internal relay; when the door is locked by the remote controller or locked
manually, the public contact of the relay will get through the normally-open contact, realizing an output of 12V voltage.
4. Key detection cable. This cable is connected to the ignition lock of the car and will
get through with the grounding wire
when the key is inserted into. (negative input)
5. Ri
ght direction indicator. The cable is connected to the positive pole of the right direction indicator of the car; an output of
12V voltage will be available when this cable is at work.
6. Left direction indicator. The cable is connected to the
positive pole of the right direction indicator of the car; an output of
12V voltage will be available when this cable is at work.
7. Negative input of door switch, which is connected to the door switch of the car; this cable will be earthed when the door is
opened. (Interior lights will be on)
a. Open the door and then close it, the reading light will be on for 10 seconds; if during this period, it is detected that the key has
been inserted into the ignition lock or the door closed, then the reading light will turn off.
b. When the key is pulled out of the ignition lock, then reading light will turn on, during this period, if the key is reinserted into
the ignition lock or the door lock, the reading light will be off; if there is not any action when the door is closed within 1
minute, the reading light will automatically turn off.
8. ON power supply detection cable. A conductive wire connected to the ON gear of the ignition lock. (When the ke
y is turned
to the ON position, a 12V output will be available)
9. Car s
peedometer detection cable, which is connected to the detection cable of car's speedometer. (When the car is
accelerated to the speed of 15km/h, the instruments unit will out
put a 500mS rectangular positive pulse to the central door
lock controller, which will control the locking of the central door lock when this 500mS rectangular positive pulse signal is
detected by the controller.)
10. Output of window closing si
gnal. When the door is locked by the remote controller, this line will be available with an
output of 12V positive current for one second and then be off. (No output)
11. Locking signal. The locking signal line connected to the central door lock of car's left front door is connected throu
gh with
the grounding line when at work. (Earthing)
12. Unlockin
g signal. The unlocking signal line connected to the central door lock of car's left front door is connected through
with the grounding line when at work. (Earthing)
13. Ne
gative pole of the power supply, which is connected to the car body, (earthing) line shall be as short as possible,
over-length will produce the interference.
