First, the central control door locks are not normal circumstances
1) can only open the door, can not close the door?
A: First determine the switch in the control gate control line is correct or not, according to trigger type is connected correctly, then check the white / black line fuse.
2) can not open the door, only to close?
A: This problem does not exist common vehicles, primarily targeted at the original vehicle anti-theft device such as "Passat, Nissan grace, Audi A6", etc., when the original vehicle anti-theft devices at work, only to the original car anti-theft devices do not (you can power off, you can also remove the battery remote control), because the original car's central locking alarm when the burglar is locked.
3) sound light, in the control does not move?
A: First detected in the control of the car door lock motor is good or bad, then check the central locking and remote control receiver module is good or bad, and then listen to the remote control pops when pressed relay have sound, so you can determine the host's good or bad.
4) remote control distance shorter?
A: Because the impact by high-frequency, coupled with the rolling code of the encoding, so no more than 10m are considered normal, as long as the remote control to move the antenna as metal-free place.
5) without any reaction?
A: First consider the host is normal, check whether the normal or non-electric central locking, consider a receiver module and the host is working properly.
6) The pressure lock settings?
A: If you find a closed immediately pop up, or open the door immediately locked up, then, is the pressure to set the lock time is too short, prior to December 2001 for the host to open the host jumper, plug in the drawings. December 2001 after the host according to the voice prompts on the line.



Second, the voice of the common faults
1) Silent
A: First check the amplifier speaker is connected correctly or not, distinguish between line and into the outlet, usually about 4 to 16 in Europe, was the correct jack is plugged in, the host is in alarm status
2) the current sound
A: Considering the interference of the power box, power box with the grounding of the host
3) The tone of "giggle" sound?
A: The main power supply box does not match with the host
4) No voice prompts (including non-timekeeping)
A: The host is not working properly
5) the volume is too small
A: Consider the right car horn connection



Third, the failure to call
1) a short distance dialing (wireless)
A: We do not put away the location of the antenna
2) can not dial
A: Consider the battery properly installed, dial device is working, the receiver box is working
3) can not make a phone call
A: Check the GSM antenna connection, and then dialing device "** 3" reset.



Fourth, the host just common faults encountered in power
1) keep the circuit after the alarm?
A: Check the relay is working, then check the wiring is correct ON Line
2) the direction of light does not blink?
A: Check the connection and the diode breakdown, the other special vehicles (such as 24V, ISUZU vehicles turn signals trigger voltage is different) plus the relay will change
3) can not remote start?
A: Check the power voltage signal line, the car can not launch a voltage higher than 5V, then check when the car can start without the key, such as "grace, Buick, Audi A6" The will not start, then check the start air-conditioning control lines, power lines and some of them a white car is then ACC, some cars are connected to IG, according to the specific situation to be connected.
4) can not be an emergency to the police?
A: Check the button switch is good or bad and the ground, then consider the quality of the host and telephone number of the set.
5) The password is not correct to the police?
A: The password is not correct.
6) The power to the police?
A: If installed on the host after 10 to 20 seconds after the reaction not with the remote control output, then we must check whether the line voltage of 3 feet, if not, as long as the warning, the host will be in alarm state.
7) The alarm horn silent?
A: Check the ground wire and should be connected, and then check the audio speakers.
8) In the case can start early warning?
A: The generator should check the signal cable is connected correctly, the signal voltage is comply with the requirements of



Fifth, start Fault
1) can not foot brake to lock the door?
A: Check the door probe cable is connected correctly, check the foot brake and then stepping down the voltage value is suitable for our requirements (special vehicles such as Mercedes-Benz series) plus the relay to convert the battery.
2) can not be the door to the police?
A: When using the key opened the door after 1 minute or 40 seconds can not be alarm, first check the door cable, the blue line voltage change value, followed by delay circuit should consider changes in the value of the door lights are generally not the host vehicle any problems, then check the phone settings are correct alarm
3) positioning the test?
A: The key to the delay by the time the navigation is always "tick" sound and reported the sound should first check the location of GPS antenna, the antenna is best placed in the position of an area as large as possible on the space where the top can not have heavy metal and Item block.



Six, the screen test
1) can not send and receive text messages?
A: Check the SIM card, the main short message center number and short message alarm number is set correctly.
2) dim and bright side?
A: After the shell open with a screwdriver adjustable resistance to rotation for the brightness.
3) garbled or blank screen?
A: The garbage may be due to line interference; blank check for power lines caused by, or the host state of alert. .



VII, 24V car control line connection
1) to avoid interference with the original car's electronic facilities (such as: tape recorders, electronic parking meter, etc.)
2) Lead 12V power box connection on the host output control lines 3 feet, while the relay back to 12V power supply.
3) turn signal relay to be installed.
4) Start the air conditioner not fulfilled.
5) central locking control switch to distinguish between the gate line voltage is 24V or 12V and ground.
