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 usually 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. Output 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. Right 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 key is turned to the ON position, a 12V output will be available) 9. Car speedometer 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 output 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 signal. 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 through with the grounding line when at work. (Earthing) 12. Unlocking 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. Negative 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. Function of controller of the central door lock 1. Locking. When all the car doors are closed, press LOCK button of the remote controller once, at this time, the direction indicator will flash once and the central door lock is closed. 2. Unlocking. At the locking state, press UNLOCK button of the remote controller once, at this time, the direction indicator will flash two times and the central door lock is opened. 3. Car-finding function. At the locking state, press LOCK bottom of the remote controller once, and at this time, the direction indicator will flash ten times quickly. Press UNLOCK button of the remote controller to quit the car-finding function. 4. Automatic prevention function. At the locking state, press UNLOCK button of the remote controller to open the lock; if the |
