Why Do Car Alarms Go Off For No Reason?
Immobilizer sensitivity
The car alarm 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. 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 directly fine-tune the sensitivity adjustment torque, but do not adjust it too low, otherwise the anti-theft coefficient of the car is very small.
Anti-theft circuit
Of course, it may also be because there is a problem with the line of the anti-theft device host, and it needs to be checked, repaired or replaced in time. But whether it's checking the line or replacing the alarm, we'd better leave it to a professional to handle it. After all, this is beyond our ability to solve, and there are many line distributions integrated in it. If the installation is not professional Or if the line is reversed, the anti-theft device will not be able to be used, and the components in the car will be burned. Therefore, friends who want to deal with it privately have to think twice, unless you are really proficient in this operation.
How to turn off the car alarm
First, find the line distribution position of the anti-theft system, which is generally located under the steering wheel and in the guard plate under the A-pillar. Then you can directly unplug the input wire of the anti-theft device. At this time, the anti-theft device is equivalent to losing its function. Of course, some anti-theft devices are protected by fuses. At this time, we need to find the corresponding fuse position (refer to the car maintenance manual), and then unplug it, which is equivalent to disabling the car anti-theft system.
