What could be a failure? What is this glitch?

Murmurs, whistling, echoes.

Since it is multiple ** at the same time, the small noise will be repeatedly amplified when two people are talking. Therefore, it is necessary for all parties involved to keep the environment as clear as possible when using multi-party call services. Here are some possible failures and workarounds:

If one party uses a poor quality headset, a first-class machine, or buckles the microphone on the table, it may cause whine and echo;

Answering the ** mobile phone or PHS, the location of the signal is not good, etc. will also cause various problems.

In the event of noise, echo, whistling and other faults, each caller checks whether the ** line interface of the fixed line is loose, and whether the mobile phone or PHS has a good signal; And be careful not to shake the cable of the handset Sometimes shaking the microphone cable may also cause a small current jitter, resulting in noise and whistling).

When the above fault occurs, you can ask the parties participating in the call to check whether they have the above situation, and if there is no improvement, you can try to hang up and redial the called party. 2. Disconnection and dropping words.

Due to the use of a special conference system for the transfer of calls, sometimes when the party answering the ** does not call for a long time, or uses PHS or mobile phones and the signal is poor, there may be a delay in signal transmission, resulting in the system terminal call in advance, resulting in disconnection and dropping. At this point, you can try to redial the other person. Thank you for your interest in telecom products and wish you a happy life.

<> can't understand your question.

This is the tire warning light. Check that there may be a tire with abnormal pressure. Sometimes there are false positives. Tire pressure monitoring uses a differential sensor, which is prone to false alarms.

Tire pressure alarm.

Unstable tire pressure can cause imbalance on the four wheels.

The vehicle will deviate while driving.

Serious ones are more likely to lead to catastrophe for fetal protection!

There are many reasons for the engine failure light to be lit, when the instrument shows this yellow engine fault light, it means that there is a problem with your car, the body has more than 10 sensors, these more than 10 sensors will cause the fault light to light up, so only with computer detection can you know that it is caused by a problem, so now there is no way to give you an accurate answer, it is recommended that you go to the nearest repair shop to test, I hope to help you.

The alarm indicator on the instrument panel is the tire pressure alarm indicator.

If you have this light, it means that your car has an automatic tire pressure detection function, and the light is on to indicate that there is a lack of tire pressure.

Go to the garage and check to see if there are any nails or anything like that.

After repairing and replenishing the air pressure, the same marked button near the longboard gear lever can clear the alarm.

The one with the exclamation mark in yellow in the picture is the tire pressure warning light.

I haven't liked any star in my life, except for Cai Xukun, it was one night in 2018, I mistakenly ate a package of expired spicy strips, gutter oil poisoning, the doctor said it was late, it was not saved, I watched TV when I was dying, Kun Kun was dancing, I immediately vomited out which star I have never liked in my life, except for Cai Xukun, it was one night in 2018, I mistakenly ate the expired spicy strips, gutter oil poisoning, the doctor said it was late, it was not saved, I watched TV when I was dying, Kun Kun was dancing, I immediately threw up.

There was a problem with the tire pressure. You check the tire pressure, if the tire pressure is normal, you reset the software, if it still doesn't work, remove it and try again.

Problems with the tires to see if they are punctured.

The picture you provide shows that the tire pressure alarm indicator is on, it should be that the tire pressure is insufficient, check the tire immediately, if the tire pressure is insufficient, there is no self-contained inflation equipment, please reduce the speed of the car to find the nearest inflation point to inflate; If the tire pressure is high, just deflate it immediately to reduce the pressure. Otherwise, you need to go to a professional repair station to check it before dealing with it. Driving safety is no small matter!

Good luck!

When the brake light is on, it proves that the brake pads have worn to the limit (brake oil level), and all the owner needs to do is to replace the brake pads! What needs to be paid attention to here is that the ABS light should not be confused with the brake warning light.

There is no fault from the dashboard alone, the dashboard can only show that there is oil, the vehicle is stationary, or the engine of the car is stopped, if the car is not displayed in the process of driving, it must be the speed line or the speed line is off or broken, to the auto repair shop on the line, quite simple.

This may be an engine failure caused by uneven oil, or it may be an engine leaking oil, all kinds of possibilities, it depends on how you deal with it, in fact, this kind of fault is very easy to deal with, just go to the car repair shop to see it, if it doesn't work, you just change the car!

You are a tire pressure monitor shows that there is a problem with the tire pressure, which is generally caused by insufficient tire pressure, check the tire in time, otherwise it is easy to burst the tire at high speed.

Tire pressure monitoring warning light: When a tire of the vehicle is deflated, the light will be on, when the light is on, please check the tire status in time to avoid danger.

The car's tire pressure alarm indicates that your tire pressure is high or low, and it is recommended to check the tire pressure of all four tires and the tire pressure is normal. The front driver's door or fuel tank cap of the car are marked with tire pressure values, generally the front and rear wheels.

In the case that the tires are normal after overhaul, the first decoder can be used to eliminate the fault code. Second, drive out at a speed of no less than 30 for a period of time.

Tire pressure sensor alarm, this you need to get out of the car to check whether the tire is punctured and leaking, if there is no air leak, see if the tire has foreign objects in the tire seam, if not, go to the tire repair store, check whether the air pressure of the tire is reduced, if it is reduced, after the inflation, restart should be able to eliminate the alarm, if it can not be eliminated, you need to go to the repair shop to check the fault code, and then deal with it according to the fault code!

This is a tire pressure alarm, maybe your tire pressure is low, or the nail is running and leaking. It is necessary to replenish the air, or it may be that the air pressure is different when the season is different.

This is an indicator of abnormal tire pressure, which is easy to appear when the weather is too cold and too hot, of course, it is also possible that the tire is punctured, get out of the car to check it, if the tire leak is not serious, it is recommended to repair it as soon as possible!

The yellow light is the tire pressure monitoring light, if it lights up, it means that there is less than one tire with insufficient tire pressure, and it should be stopped immediately for inspection, and there is also a situation that the light on the car will also be on after the tire is changed, and it needs to be restored.

If the tire pressure is too low, you have to go to the car shop, go to the car shop to pressurize or change the tire, there are only these two methods, if you repair it yourself, then you can repair the tire, but I still recommend you to go to the 4S shop.

The tire pressure monitoring alarm light is on, it is a tire failure, check whether the pressure of the four tires is normal, whether there is a lack of air for other reasons, paste it and repair it to replenish the air normally.

A fault is a state in which a system is unable to perform a specified function. Generally speaking, a fault is an event in which a part of a system fails to function, resulting in the deterioration of the entire system function.

Equipment failures generally have five basic characteristics: hierarchical, propagating, radioactive, delayed, uncertain, etc.

Basic characteristics of the failure:

1. Hierarchical: Complex equipment can be divided into systems, subsystems, components, and components, showing a certain hierarchy, and related to it, the failure of the equipment also has hierarchical characteristics, that is, the failure of the equipment may appear at different levels such as systems, subsystems, components, and components.

2. Propagation: The failure of the component will lead to the failure of the department, the failure of the component will cause the failure of the system, and the fault will spread along the path of the component, subsystem, and system.

4. Delay: There is a certain time process for the occurrence, development and propagation of equipment failure, and this delay characteristic of equipment failure provides conditions for the early prediction of failure.

5. Uncertainty: The occurrence of equipment failure is random, ambiguous, and unknowable.

This fault light is the brake disc indicatorThe brake disc indicator is used to show the wear of the vehicle's brake disc. Generally, the indicator light is off, and when the brake disc is faulty or excessively worn, the light lights up and turns off after repair.

Brake disc indicator icon:

The brake disc, simply put, is a round disc that rotates when the car is moving. If the brake caliper clamps the brake disc and generates braking force, it clamps the brake disc to slow down or stop when the brake is pressed. Brake discs brake well and are easier to maintain than drum brakes.

The brakes have disc brakes, drum brakes and air brakes, and many older cars have front and rear drums. Many cars have disc brakes front and rear. Because the disc brake has better heat dissipation than the drum brake, it is not easy to produce thermal decay in the high-speed braking state, so its high-speed braking effect is good.

However, at low speed cold brakes, the braking effect is not as good as drum brakes. **More expensive than drum brakes. Therefore, many middle and high-end cars use full disc brakes, while ordinary cars use front disc and rear drums, while relatively low-speed, and need large braking power for trucks and buses, still use drum brakes.

The drum brake is sealed, shaped like a drum, and there are many brake pots in China. It turns when driving. There are two curved or semicircular brake shoes fixed on the inside of the drum brake.

When stepping on the brakes, the two brake shoes are stretched outward under the action of the brake wheel cylinder, and the brake shoes are propped up and rubbed against the inner wall of the brake drum to play the role of deceleration or stopping.

E1 is the fault of many household appliances**, different types of household appliances E1 represents different specific meanings, here is an example of a washing machine to illustrate. The appearance of E1 in the washing machine indicates that the drain is faulty or the drain is overtimed, and there are generally the following reasons:

1. Check whether the drainage pipe is smooth, if it is smooth, it means that the water level sensor is faulty, and if the drainage is not smooth, it means that it is blocked.

2. If the drainage is very small or does not drain, first confirm whether the drainage pipe is lowered, and the drainage pipe cannot be placed in a high position, which is prone to the problem of non-drainage.

3. If it is not placed too high, check whether the drain pipe is blocked by foreign objects or the water pipe is too bent, if the flow of water is very small, the drain pipe should be blocked.

4. It may also be that the drain valve controller loses its effect, and the washing machine cannot control the drain valve, resulting in the water not being discharged.

5. If the above methods cannot be solved, it is recommended to find after-sales maintenance personnel for maintenance, and do not disassemble and repair without authorization.

The setting of this wrench maintenance reminder is actually the same as the function of the alarm clock, just a reminder. You can set the time of the next maintenance according to your actual situation, or ignore this reminder, learn how to eliminate the operation of the maintenance prompt online, and eliminate it yourself every time you see it. The oil change can be decided according to your own working conditions, and it is generally 10,000 mm.

Reasons for the engine failure light: 1. The sensor is damaged, the contact is poor or the signal is interrupted; 2. Poor engine maintenance; 3. The quality of fuel and oil is not good; 4. The combustion of the mixture is insufficient; 5. Spark plug failure, ignition coil failure; 6. The fuel pump is faulty and the oil circuit is blocked; 7. The air conditioner filter is blocked.

1. Sensor problems; The sensors mentioned here include water temperature, crankshaft position, air flow, intake air temperature, oxygen sensor, etc., when these sensors are damaged, poor contact or signal interruption, the ECU of the car can not accurately obtain the engine data, at this time it will cause the engine fault light to turn on. 2. Maintenance problems; Poor engine maintenance is the most common cause of engine failure to light up. We know that the vehicle has a certain maintenance cycle, if the owner does not maintain on time, coupled with bad driving habits, then it will increase the burden of engine operation, and finally can only remind you through the fault light to care about your car 3, oil quality problems; The oil quality here includes fuel and engine oil, we know that the fuel filled by the car is generally marked, and the engine oil is also semi-synthetic and fully synthetic, the manufacturer will generally recommend the owner to use which grade of fuel, which type of engine oil, if the owner does not add as required, it will cause wear and tear of the engine in the long run, and the fault light is not to blame.

Poor combustion of the mixture; The failure of the spark plug, ignition coil, fuel pump, and oil circuit blockage of the engine will cause poor combustion of the engine mixture. Poor combustion of the mixture is caused by the problem of engine carbon deposition or knocking, and these will eventually be detected by the engine's oxygen sensor and reported to the ECU, which will naturally turn on the fault light to warn of the intake air intake problem; When the engine burns, it needs to take intake, the air filter element is very important in this process, if the air filter element of the car is not clean, it will affect the air intake of the car if it is not cleaned regularly, and it will be blocked for a long time, and if it is serious, it will cause the engine failure light to turn on. pressurization issues; Intake booster lines and turbochargers can also cause engine failure lights to illuminate.

The most common of these is turbocharger damage, while the vehicle can also experience symptoms such as oil leakage, high oil consumption, loss of power, metal noise, and blue or black smoke from the exhaust pipe. 7. Exhaust problems; Rear oxygen sensor, three-way catalytic converter, exhaust camshaft and bearing. The most common of these is a failure of the three-way catalytic converter that causes the engine failure light to illuminate.

The use of leaded gasoline, the use of leaded or silicone lubricant additives, the bump of the three-way catalytic converter, and the failure of the engine oil supply system are some of the factors that can easily cause the failure of the three-way catalytic converter. anti-theft system; If the car's electronic immobilizer fails, or if the immobilizer does not match the engine electronic controller, the immobilizer system will also cause the engine to not work properly and the engine fault light will be lit at the same time.
