The car alarm keeps ringing, which is probably because the sensitivity of the anti-theft device is too high, causing the device to sound the alarm when it feels a little vibration. As for how to solve this problem, first find the main engine of the anti-theft device, which is usually located under the steering wheel and the guard board under the A-pillar. Then adjust the sensitivity adjustment knob directly, but do not adjust it too low, otherwise the car's anti-theft coefficient is very small

What's the matter with the sudden automatic alarm horn

The car alarm keeps ringing, which is probably because the sensitivity of the anti-theft device is too high, causing the device to sound the alarm when it feels a little vibration. As for how to solve this problem, first find the main engine of the anti-theft device, which is usually located under the steering wheel and the guard board under the A-pillar. Then adjust the sensitivity adjustment knob directly, but do not adjust it too low, otherwise the car's anti-theft coefficient is very small.
As we all know, the alarm is an alarm device installed in the car. However, some netizens reflected the phenomenon that the car called the police at midnight for no reason. At first, they thought it was some night cats who were making trouble, but they still called the police when nothing hit the car. So, what should we do if the car alarm goes off in disorder? First of all, we need to know where the problem is.
Of course, the circuit of the anti-theft device may also be due to a problem with the circuit of the anti-theft device host, which needs to be checked, repaired or replaced in a timely manner. However, whether it is to check the circuit or replace the alarm, it is better to hand it over to the professional personnel for handling. After all, this is beyond the scope of the solution. In addition, there are many integrated circuits distributed inside. If the installation is not professional or the circuit is reversed, the anti-theft device can not be used, and the components in the vehicle can be burned. Therefore, if you want to deal with it privately, you should think twice before you act, unless you are really skilled in this operation.
Reasons for alarm of anti-theft device without reason:
(1) Controller failure: It may be caused by the failure of the alarm itself or the triggered sensor failure. (2) Trigger sensitivity is too high. Occasional alarm will interrupt the rest. (3) If the door side switch or the hood switch or the trunk switch is closed, the door is not closed tightly. If the trigger wire is grounded, the wire is shorted. They will keep calling until the battery is dead. In this case, the sensitivity of the immobilizer can be adjusted on the immobilizer control box.
