What's the matter with the car's automatic alarm horn speakerr ringing suddenly
May 11, 2022
The car alarm speaker keeps ringing, most likely because the sensitivity of the anti-theft device is too high, causing the device to feel a little vibration and it will sound the alarm speakers. As for how to solve it, first find the main engine of the anti-theft device, which is usually located under the steering wheel and in the guard plate under the A-pillar. Then fine-tune the sensitivity adjustment knob directly, but don't adjust it too low, otherwise the anti-theft coefficient of the car is very small.
As we all know, the alarm horn speaker is an alarm device installed in the car. However, some netizens reported such a phenomenon that the car called the police in the middle of the night for no reason. At first, they thought that some night cats were at fault, but they still called the police when nothing touched the car. So, in the end what to do with car alarms, you must first know where the problem is.
Of course, the circuit of the anti-theft device may also be due to a problem with the line of the anti-theft device host, which needs to be inspected, repaired or replaced in time. But whether it is to check the line or replace the alarm, it is best to leave it to a professional to deal with it. After all, this is beyond the scope of the solution. In addition, many lines are integrated in it. If the installation is not professional or the line is reversed If so, the anti-theft device will not be able to be used, or the components in the car will be burned. Therefore, friends who want to deal with it privately have to think twice, unless they are really proficient in this operation.
The reasons for the alarm of the anti-theft device for no reason:
(1) Controller failure: It may be caused by the failure of the alarm itself or the triggered sensor failure. (2) The trigger sensitivity is too high. Irregular alarms will interrupt the rest. (3) The door side switch, cover switch or trunk switch is closed, that is, the door is not closed tightly. The trigger wire is grounded, the wire is shorted. It will be called endlessly until the battery is dead. In such cases, the sensitivity of the immobilizer can be adjusted on the immobilizer control box.
