Tire pressure monitoring can only detect three tires, and one can t, what s going on

I guess there was no reset, right? You do the tire pressure study again, and it should be fine.

After the tires have been replaced, the tire pressure monitoring system must be reset, also known as "tire pressure learning".

Working principle: Each tire is equipped with a tire pressure sensor, and the tire pressure is transmitted to the tire pressure control system of the car through wireless methods, and the data meter of the car can display the tire pressure of each specific position. For example:

If the left front tire is changed to the right rear wheel, if the tire pressure system is not reset, the car will recognize the original tire and still determine that it is the left front wheel, not the right rear wheel.

How do I reset it? There are detailed instructions in the Chinese user manual for the car. But there is one place where there are Chinese translation errors that may misunderstand us.

Here's how to reset it:

1. After stopping and turning off the engine, pull the handbrake.

2. The car is powered on, but do not start the engine.

3. Press the lock and unlock buttons on the remote control at the same time, press and hold for 5 seconds, and listen to the car whistle twice (the sound is not too loud).

4. Next, follow the left front wheel. Reset each tire in the order of right front, right rear, and left rear.

5. Reset the left front wheel first: unscrew the valve cover on the tire, and continuously deflate (or refill) the tire until you hear a short horn of the car, and the tire is set. The deflation time may be 10 to 20 seconds.

If you don't hear the horn, keep it. [There is a big translation error here in the Chinese manual, which may mislead some riders: the Chinese translation says that the car whistle will last 30 seconds, but the original meaning is that you may have to wait for a while to deflate, and the time may be as long as 30 seconds, and the car will whistle to confirm that it is set.]

I went to the American Kaidi BBS to find the original English description of this step to verify].

6. Then follow the same method and the above order to reset the other three tires.

7. After the last tire is set, the car will immediately whistle twice. At this point, the tire pressure reset is complete!

8. All you have to do is to charge the air pressure of each tire, drive away!

Note: The car control system requires that the left front wheel reset should be completed within 2 minutes, and all four wheels within 5 minutes. If this time passes, you will need to start the reset again.

Some special experiences:

1. When resetting, you should find a place to pump up, so that you can inflate the air immediately after the reset. If you don't complete the reset once, you may have to do it several times.

2. Please note that there should be no strong magnetic field near the car. The signal transmission between the tire and the car is via wireless signal transmission. The external magnetic field is likely to affect tire pressure learning. I guess that's what happened to me.

3. For reference: I saw an old beauty on the American Kaidi BBS that if it can't be reset according to the deflating method, you can find a magnet and put it on the tire valve, and force the car control system to identify the tire through magnetic induction. But I haven't tried it.

1: Built-in tire pressure monitoring, at the beginning of the car has not moved, the displayed tire pressure is the tire pressure when the car was parked the night before. So it is necessary to visually check the tire pressure before getting into the car.

2: If your monitor shows three tires not showing, there are two reasons. One is that there is a problem with the receiver inside the display, and the other is that there is a problem with the sensors of the three tires.

3: Under normal circumstances, the frequency of problems with three sensors at the same time is relatively low, so it may be the cause of the display. In the case of making sure that the pressure of all four tires is normal, it is recommended that you move the car to see, if it is shown then there will be no problem.

4: If the car is still not displayed, then go to the place where it is installed and ask them to check, find the reason and replace the faulty parts.

If the pressure of one of the four tires is alarmed, it proves that there is a problem with the tire, which may be punctured.

If the tire pressure monitoring system warning light is on during driving, please keep calm, do not panic, immediately reduce the speed of the car and avoid hitting the steering wheel and braking sharply, and immediately lift the lead to check the tire. If you have your own simple inflation, you can drive to the side of the road, test and inflate each tire. If you don't have one, you can drive slowly and find the nearest service area or car repair shop or 4S shop.

Precautions for the use of tires.

Do not use the spare tire as a normal tire. In the process of using the vehicle, if it runs 100,000 to 80,000 kilometers, the good customers will use the spare tire as a good tire and the original tire as a spare tire, which is absolutely undesirable. Because the use time is different, the degree of tire aging is also different, so it is very unsafe.

Do not overload the tires. The structure, strength, pressure and speed of the tires are determined by the manufacturer's strict calculations, and the tires that are not used in accordance with the standards and overloaded will affect their service life.

The only possibility for this to happen is a damaged pressure sensor on the hub. The pressure sensor is damaged and cannot send back the tire pressure signal, so the tire pressure monitoring fails. Each tire is equipped with a tire pressure sensor, which transmits the tire pressure to the car's tire pressure control system wirelessly, and the car's data meter can display the tire pressure of each specific position.

Changing tires for a car with tire pressure monitoring is the same as changing a tire as usual, but a car with tire pressure monitoring needs to "relearn", that is, reset, after changing a tire. When the tire is changed and not reset, it may cause a tire pressure alarm, and it is necessary to reset it to eliminate the tire pressure alarm.

The reset steps are as follows:

1. Power on the car, but you can't start the engine.

2. Press the lock and unlock button on the remote control at the same time when the object collapses, and release it when you hear the car ring twice.

3. Re-set each tire in the order of left front wheel, right front, right rear and left rear. Reset the left front wheel: Unscrew the valve cap on the tire and deflate the tire continuously, which may last for 10 to 20 seconds.

4. If you don't hear the horn all the time, you have to keep playing it. Until you hear a short horn from the car, it means that the left front wheel is already set. As soon as the last tire is set, the car will make two short honks.

At this point, the tire pressure reset is complete! The remaining three tires are also set up according to the same steps, all are inflated, and the tire pressure monitoring reset is completed.

After the tyre is replaced, the tyre pressure monitoring system must be set up again. Its working principle is that each tire is equipped with a tire pressure sensor, which transmits the tire pressure to the tire pressure control system of the car through wireless transmission, and the data instrument of the car can display the tire pressure of each specific position.

If the tire pressure system is not reset, the car will still recognize the original tire, but not the new tire.

If the tire pressure alarm is still alarmed after resetting the tire pressure monitor, it is possible that the tire pressure monitoring alarm is faulty and needs to be repaired or replaced. After installing a tire pressure monitoring alarm on the car, the tire pressure can be monitored in real time to prevent safety accidents caused by abnormal tire pressure.

It could be that a vehicle's tire pressure sensor is malfunctioning.

There is no signal in the tire pressure monitoring, and it is likely that the signal is interfering or the sensor is broken. Automobile tire pressure monitoring installs an automobile tire pressure monitoring sensor inside each wheel, it can accurately measure the pressure and temperature inside the tire, the sensor sends the pressure value and temperature value of the tire to the body controller according to a certain law through wireless form, BCM sends the information frame to the dashboard through the CAN bus, and the driver obtains the pressure value and temperature value of each tire through the dashboard display.

When the pressure or temperature value of a tire changes more than the alarm value, the dashboard can accurately display the position of the alarm tire and send out an alarm. At the same time, the low-frequency antenna installed at the position of each tire fender communicates with the BCM, and analyzes and converts the operation information of the BCM tire pressure monitoring sensor into 125 kHz low-frequency wireless data and transmits it, and the automobile tire pressure monitoring sensor will receive this low-frequency wireless signal, and then work according to the analyzed operation information.

Hello, check the tire pressure sensor, signal acceptance antenna,

Hello! The sensor is abnormal, try to match it, and if it doesn't work, you have to change it.

According to the provisions and requirements of the international GBT2978-2008 standard: standard tires:. Adjust the tire pressure to the standard tire pressure.

1. Winter: Adjust the standard air pressure of automobile tires appropriately. Summer: according to the lower limit of the standard air pressure of automobile tires. In summer, the car is parked in the open air, and the air pressure can generally be about lower than the standard to avoid high temperature punctures.

2. Tire condition: new tires: the tire pressure can be adjusted according to the standard air pressure of automobile tires.

Old tires: Appropriately adjust the tire pressure according to the automobile tire pressure standard, and if the wear is serious, the lower limit of the automobile tire pressure standard shall be pressed. Soft tires:

That is, the tires with comfort patterns are appropriately adjusted according to the standard tire pressure. Hard tires: i.e., steerable tread tires, according to the lower limit of the standard tire pressure.

Hello, the tire pressure inconsistency deviation is not too normal, you can try to set the tire pressure to the left and right, or according to the air pressure marked on the car,

Hello, the tire pressure is not the same, and it is okay to charge it consistently.

Hello, gas on it,
