Why does the alarm sound while driving?

When the humidity of the outside environment is lower than 4 degrees, there is a sound of temperature alarm, which is normal, if the temperature is not very low, then it is another matter View the original post

Warnings I've encountered: 1When the ambient temperature is lower than 4 degrees, the starting and driving processes will be warned, and then you can see the instrument panel temperature display flashing.

2.When the maintenance time is up (4s will set a value for each maintenance, generally 5000 km), it will warn every time it starts, and a small wrench flashes at the bottom left of the dashboard. 3.

Outside, after the car is stopped, when the door is opened, a warning is always issued, that is, the lights are not turned off normally. 4.There are also seat belts and hand brakes, which are common.

Mine, 1900km. I have encountered the problem that it does not ring when it rings in 2 or 3 drives, which is the same as the problem of the landlord. Another time was when it was activated, it sounded 3 times in a row, and then it didn't sound again, and when it sounded, I noticed that the yellow light of the airbag was on.

I'm going to take the time to go to the 4S store to check it out. View the original post

If there is a sound, it may also be the tire pressure!! Check the tire pressure of each tyre and whether the tyre is stuck in anything. I was like this during the Chinese New Year, when I pricked something, it would dingle on uneven roads, but when you go to the meter at this time, there is no warning (the tire pressure may not be much lower)!

It wasn't until the next day that the tire pressure alarm showed on the meter, and the tire pressure was already much lower at that time. View the original post

In the course of daily driving, if you notice that the alarm in the car is sounding, check whether someone is driving in time. If it is not man-made, it needs to be checked. If it can't be solved reasonably, you can call ** to the 4S store to consult their handling opinions.

It is believed that this problem has been bothering some car owners for a long time, because it is only some wild cats wandering around the car that causes the car alarm to go off. But after observing for a while, I found that the car called the police for no reason. So, to answer this question, let's talk about how to get rid of car alarms.

The sensitivity of the trigger is too high, which is one of the reasons why many car alarms go off for no reason. These alerts. This alarm will only work if there is vibration or some noise is relatively low.

Sometimes, if the vibration is too loud, it will also cause the car alarm to work. If the alarm is too sensitive, there is a sensitivity adjustment button on the vibration sensor of the burglar alarm, which can be fine-tuned.

The doors are not closed, not only the doors, but also the hood or trunk of the car. When one of the parts is not closed tightly, the car's alarm works. If left untreated, the alarm will go off until the car's battery dies or the door closes tightly.

Controller failure is also possible When the controller of the alarm fails, short-circuits, or malfunctions, the car alarm will also alarm. If it is judged that there is a problem with the car alarm, it needs to be dealt with in time. The car alarm keeps ringing, probably because the sensitivity of the burglar alarm is too high, and when the device feels a little vibration, it will cause the alarm to sound.

As for how to solve it, first find the host of the anti-theft device, which is generally the guard plate under the steering wheel and under the A-pillar. Then adjust the sensitivity adjustment knob directly, but don't adjust it too low, otherwise the anti-theft coefficient of the car is very small.

Of course, the anti-theft circuit may also be because the circuit of the anti-theft alarm host is faulty, and it needs to be checked, repaired or replaced in time. However, whether it's checking the circuit or replacing the alarm, we're better off leaving it to a professional. After all, it's beyond our ability to solve problems.

In addition, many circuits are integrated inside. If the installation is not professional or the circuit is reversed, the burglar alarm will not work, and the interior parts of the car will be burned out. So friends who want to deal with it privately should think twice, unless you are really proficient in this operation.

It may be because the alarm has failed, or it may be because of the failure caused by the trigger of the sensor, so when the car has this situation, you must check the vehicle in time, this is not a small matter, because this can disturb the people.

In this case, it may be that your car door is not closed tightly, which is why it rings, or it may be because the trigger sensitivity of the car is too high, so it will make such a noise.

The sensitivity of the trigger is too high, the door is not closed tightly, and the controller is malfunctioning, these are the reasons for the alarm sound, so it can be improved by checking it first.

It must be because some parts are malfunctioning, because you are not wearing a seatbelt, or because there is a problem with the connection of the engine, so it makes the noise.

Such a problem often arises in real life, where the car calls the police for no reason when it is not in any danger. Not only will it cause some harassment to the surrounding environment, but it will also make the owner particularly annoyed. What happens when a car alarm calls the police for no reason?

Here are a few possible reasons.

(1) Controller failure: It may be caused by the failure of the alarm itself or the failure of the triggered sensor.

b) The trigger is too sensitive. Irregular alarms will interrupt the break.

3) The door side switch or cover switch or trunk opening and closing is not closed tightly. When the trigger wire is grounded, the wire is short-circuited. It will keep screaming until the battery is out of power.

In such cases, the sensitivity of the immobilizer can be adjusted on the immobilizer control box. Generally, the anti-theft device control box is installed under the instrument, and it can be seen after disassembly, and there is a spiral knob on it, and the sensitivity can be adjusted by turning. It is recommended that the sensitivity be reduced to the state of boarding the tire car with your feet and not alarming.

It is recommended to use a silent state when parking and using an anti-theft device, and the anti-theft device can still prevent theft without sound. When the car is started abnormally in the control circuit, it will automatically power off and alarm, and turn on the sound anti-theft. If the immobilizer detects a constant vibration, it will affect the rest of others and consume the car's power.

Hello! The alarm sound is emitted when the car is started and driving, and there are the following situations: 1. The combustion state is not good

The poor combustion state of the engine is the main reason why the engine fault light is on, and the combustion state of the engine is not good due to the inaccurate coordination between the various parts of the engine, which causes the engine indicator light to be on.

2. Engine knocking: when the engine detonation, the engine's indicator light will also light up, the general engine knocking is divided into car weakness, car weakness and engine noise is too loud and the engine has an obvious knocking sound, if the vehicle only appears weak, the engine indicator light may or may not be lit, and when the latter two situations occur, the engine's indicator light will light up.

3. The internal reason for the engine fault light to be on: the fuel quality is not good or the inside of the engine cylinder is not clean, and the engine fault light will also appear when the carbon deposition is serious, and the owner needs to check the working condition of the engine in time to avoid causing greater failures. P.S

Precautions for engine maintenance: 1. Antifreeze: Automobile antifreeze needs to be checked in time in winter, especially in the northern region, when the temperature is low, if ordinary water is used instead of antifreeze, it is easy to freeze, and the volume of water becomes larger after freezing, and it is easy to expand the water tank, and there are many impurities in the tap water, and there will be scale after a period of use, blocking the pipeline, and the water temperature is too high.

2. Engine oil: automobile engine oil is indispensable in daily maintenance, engine oil can not only play a lubricating effect, but also play a cooling effect, when adding engine oil, if inferior engine oil is added, the lubrication of the engine is not sufficient, resulting in abnormal wear of the engine, affecting the normal performance of the engine.

3. Air filter: The air intake system needs to be checked by the owner in time when using the car in daily life to check whether the air filter can work normally, the failure of the air filter will lead to engine failure, and the inferior air filter will lead to insufficient air intake, and the engine computer will misjudge and increase the generation of carbon deposits.

Summary. The vehicle alarm will give an audible and visual alarm when there is illegal entry when parked, and when it is bumped and other large vibrations.

Hello, the answer has been sorted out for you. In the event of vibration on the body of the car and the door is opened with a non-main key, the immobilizer will call the police.

The vehicle alarm will give an audible and visual alarm when there is illegal entry when parked, and when it is bumped and other large vibrations.

Only after locking the car, forcibly opening the beam, dust, starting the car, the slag mold door or the trunk door will ring. Ordinary vibrations (such as kicking a wheel or slapping a car body) are silent.

1.The alarm is too sensitive, so if there is a little wind and grass around the car, it will keep ringing, and this situation can be adjusted.

2.If the door knock switch fails, the alarm will also sound. You need to go to a repair point for repairs.

3.The sensitivity of the anti-theft sensor is too high, but this is this adjustment, there is a sensitivity adjustment torque on the anti-theft vibration sensor, and you can fine-tune it.

How car alarms work:

When you knock or shake the sensor to make it vibrate, the ball rolls inside the cylinder chamber. When it rolls away from a smaller secondary electrical contact element, the circuit formed by this secondary electrical contact element and the ** electrical contact element is disconnected. At this point, the switch will turn on, indicating that the controller ball has been displaced.

As the ball continues to roll past other secondary electrical contact elements, the circuit closes and disconnects until the ball finally stops rolling.

If the vibration of the sensor intensifies, the ball rolls longer and passes through more secondary electrical contact elements before it stops rolling. If this happens, the controller will receive a short-time pulse current from all the individual circuits. The controller can measure the intensity of the vibration based on the amount and duration of the pulse received.

If the ball only rolls from one contact element to another, the controller may not trigger an alarm at all. If someone hits the car and causes a large displacement, the vehicle may sound an alarm signal: the horn goes off, or the headlights flash.

If the ball rolls for a long distance, the controller will sound the alarm across the board.

It is basically composed of two metal contacts, with the longer elastic metal contact on top of the other metal contact. You can easily set these contacts to a simple switch: when they touch each other, current passes through.

When the car shakes violently, the elastic metal contacts also shake and come into contact with the contacts underneath, creating a closed circuit temporarily.

The solution to the alarm on the car keeps ringing is: 1. Find the host of the anti-theft device, and directly fine-tune the sensitivity to adjust the torque; 2. Check the line or replace the alarm. The reason why the alarm on the car keeps going off is:

1. The sensitivity of the immobilizer is too high; 2. There is a problem with the circuit of the immobilizer host; 3. The engine cover is too high. The functions of the on-board alarm are: 1. Trigger status recognition function and anti-robbery function; 2. The door is not closed for warning; 3. Remote control to open the suitcase; 4. Intrusion warning, power-off memory; 5. Engine locking, external emergency release; 6. The remote control and the host code matching method. Hope!

Hello It may be due to the sensitivity of the immobilizer is too high, and if you experience a little vibration, then the alarm will be sounded, and such a situation needs to be repaired as soon as possible, otherwise it will affect the normal operation of the car.

The two main reasons why the vehicle alarm is going off are that it is too sensitive, and the other is that it is faulty.

The sensitivity of the alarm is too high, and an alarm signal will be sent out as soon as there is a collision with a foreign object.

But never buy food and wear it hundreds of times. Don't think that people will do it without you looking at it, and you can give up. You look at the things you like, is to use your own income, change Hao Le and fat one bridge Nai waving.

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 sound the alarm. The solution is to first find the main engine of the immobilizer, which is generally under the steering wheel and in the guard plate under the A-pillar. Then directly fine-tune the sensitivity adjustment twist of the spirit pants pie, but don't adjust it too low, otherwise the anti-theft coefficient of the car is very small.

1. The sensitivity of the anti-theft device is too high, and there is a sensitivity adjustment torque on the anti-theft vibration sensor, and you can fine-tune it.

2. The main control door is faulty. It is commonly known as the failure of the door touch switch.

3. The alarm is too sensitive, and sometimes the wind blows. The alarm adjustment box is generally under the dashboard, and there is an adjustment knob on it, and you can adjust it yourself. You can also find the professional who installed the alarm for you to debug.

Precautions for the installation of car anti-theft devices.

Anti-theft systems are not a panacea, and now many cars are pre-installed with on-board computer anti-theft systems before leaving the factory. When the key chip data is consistent with the pre-stored data of the on-board computer, the computer will notify the relevant system to start working and allow the engine to start. Cars with their own on-board computer anti-theft system do not need to install electronic anti-theft devices.

If installed, it is easy to have a system conflict with the anti-theft system installed in the original car; If you must install an additional electronic immobilizer, please pay attention to separate it from the ignition system, otherwise it will cause the engine to fail to start and other failures. When there is a fault, do not disassemble it by yourself, you can go to a professional car lock shop and use a professional decoder to clear the fault code.
