What should I do if the tire pressure light always has false alarms, but I can t check the fault?

The tire pressure light always has a false alarm but can not detect the fault can be said to be very anxious, the car itself has no problems, but the computer has a false alarm, so you only need to reset the tire pressure to remove the annoying exclamation mark.

In order to solve this problem, here is how to initialize the tire pressure with one click.

Before introducing the one-click initialization method, let's take a look at the standard tire pressure initialization process. In the first step, turn the iDrive knob to the "Vehicle Information" menu to cut in. Step 2: Select the "Vehicle Status" option in "Vehicle Information".

The first item in the "Vehicle Status" menu is "Tire Loss Monitoring", which tells us the tire pressure status of the vehicle's 4 wheels. The second is our goal of "Confirm Tire Pressure", press the iDrive knob to confirm that this option is selected. As a result, a dialog menu appears, and you can do it all by selecting the "Tire Pressure Initialization" option.

The above is the standard "tire pressure initialization" steps, and the following is an introduction to the one-click initialization of tire pressure method. The first time you need to repeat the above steps.

When you reach the penultimate step above, press and hold any number button from 1-9 on the control panel of the air conditioner with your finger. For example, if we select the "5" button as a reference, press and hold to store it, after saving, the next time we freeze the screen on the main interface, we only need to tap the previously stored number button "5" on the air conditioning panel to reach the "tire pressure initialization" option we need.

The "Tire Pressure Initialization Operation" can then be confirmed via the iDrive knob.

It may be that the tire pressure sensor itself is faulty, causing the tire pressure light to always give false alarms.

This is not necessarily a tire pressure problem, but it may also be a faulty tire pressure sensor. It is recommended to get out of the car to see if the appearance of the tire and the actual situation of the air pressure are normal, if there is no obvious flattening. Most of that is a faulty tire pressure sensor.

It could be that the tire pressure sensor itself is malfunctioning.

Take the car to a repair shop to have it inspected and call a professional to fix it.

If you can't see this kind of problem, you can go to a repair shop or a 4S shop.

If there is no problem with the inspection, it is really a serious problem.

If you can't find a problem, it's hard to do it.

Let's go to a special repair shop.

This is not necessarily a tire pressure problem, but it may also be a faulty tire pressure sensor.

Go to the repair shop to get a tire replaced, or check if there is a problem with the tire**.

Hello dear, the tire pressure of the vehicle is not right, and the alarm light is not on, the reasons are as follows. First, the deviation related to the tire pressure before the vehicle does not reach the relevant state of the tire pressure alarm, and the general tire pressure deviation can only be alarmed normally on the left and right. The second is that there is a fault in the tire pressure system of the vehicle, which is necessary to use the computer to read the fault**, and the tire pressure sensor is checked by the checker, and if there is a problem, it needs to be replaced in time.

Thirdly, the problem of the tire pressure system program has led to this phenomenon, which is the need to redo the matching reset of the tire pressure system program. Hello, I wish you a happy life, if you have any questions, you can consult at any time, Huiyan I will reply to you as soon as possible.

The tire pressure warning light on the dashboard of the car is on, but there is no abnormality in the observation of the tires, and the possible reasons are:

1. It may be that the tire is leaking very slowly, and the phenomenon of air leakage is extremely inconspicuous and cannot be observed by the naked eye. Usually when the warning light is on, the driver will check the four tires of the car for the first time, if the phenomenon is not obvious, it will make the driver have an illusion.

2. The system is faulty and false alarm. For some reason, the sensor or receiver template is broken or the wiring is broken, which leads to the wrong tire pressure detection.

3. When the vehicle is driven for a long time, the temperature of the tire will become high, and the tire pressure will also increase due to the effect of thermal expansion and contraction. When the tires have cooled down, the tire pressure alarm is automatically eliminated.

Notes:

Regardless of whether the car's tire pressure system is faulty or not, when the tire pressure warning light is on, the driver should stop safely and lean on the side of the road as soon as possible to check whether the tire is faulty.

If it is found that the tire pressure system is faulty, resulting in a false alarm and triggering a tire pressure alarm, the tire pressure alarm light can be directly eliminated in this case. There is a button "set" button in the settings of the car control instrument to reset the tire pressure and manually turn off the alarm light.

Tire pressure that is too high or too low can cause a tire pressure alarm, and it is usually difficult to observe the abnormal tire pressure with the naked eye, except in very serious cases. It is recommended that the car should be equipped with a tire pressure gauge, when the tire pressure alarm, the tire pressure can be checked through the tire pressure gauge, and if the tire pressure is not abnormal, it may be a tire pressure system failure, reset it.

The situation you said is likely to be caused by the nerves of the tire pressure detection system of the vehicle driving computer, after the re-ignition is started or the reset button of the tire pressure monitoring is pressed, and the tire pressure monitoring is restored to normal with one button.

The tire pressure light is on, but the tire is fine, the reason is that the tire pressure is too high or the tire pressure is low, and the driving time is too long. 1.It may be a tire leak, the air leak is not prominent, and it cannot be seen by the naked eye; 2.Or the tire pressure system sensor is malfunctioning, causing a false alarm.

If the tire pressure monitoring light is on due to a punctured tire, this condition usually causes a very slow air leak, which can be measured using a tire pressure gauge. Sometimes the tire pressure monitoring light is on, it may be that the tire pressure is too high, and in the general international norms, the standard tire pressure pump standard is there; Enhanced tire pressure is in the range of; The maximum should not be higher.

Therefore, when a tire is exceeded, it will also cause the tire pressure monitoring light to turn on. The tire pressure monitoring light is on due to the low tire pressure driving time for too long, which usually occurs when the tire pressure is too low in a certain tire, and the high-speed operation will cause the tire temperature to become high, resulting in an increase in tire pressure, at this time, you should stop immediately to rest or replace the spare tire.

Hope to help you, friend, I wish you a good mood every day!

The situation you said is likely to be caused by the nerve of the tire pressure detection hole bush system of the vehicle driving computer, and after the re-ignition is started, or the hall is to press the reset button of the tire pressure monitoring, and return to normal with one button.

The tire pressure alarm but the tire is not abnormal because the air leak is extremely slow and not obvious, the tire pressure monitoring system is broken, and it may be a false alarm. The possibility of false positives is also quite high. If you don't find any problems after checking all the items, you can be sure that it's a false positive.

If there is a false alarm, just eliminate the tire pressure warning light.

The tire is pressed to the nail, and the nail is stuck on the tire, the tire is leaking very slowly, the time is short, the tire deformation is not obvious, it is not visible to the naked eye, and it is necessary to use a tire pressure gauge to measure whether there is a difference in tire pressure. If you don't have a tire pressure gauge, go to a repair shop to get it measured. Otherwise, a long-term air leak will cause the tire pressure to be too low, and a long time of low tire pressure may lead to a puncture.

Principle of tire pressure monitoring system.

The pressure sensor installed in each tire is used to directly measure the air pressure of the tire, and the pressure information is sent from the inside of the tire to the receiver module by using a wireless transmitter, and then the air pressure data of each tire is displayed.

When the tire pressure is too low or flat, the system will automatically alarm. If the Yanchangzhao sensor or receiving module is broken, the tire pressure will alarm, so that the driver can check the problem as soon as possible, find the problem, and solve the problem.

Tire pressure alarm but the tire is not abnormal, it should be caused by the false alarm of the tire pressure monitoring of the car.
