How to eliminate the faulty light? What to do if the light is malfunctioning and the light is on

If the light is faulty, the light may be broken, the bulb is in poor contact, or the fuse is blowing. If you notice that the light is faulty and the light is on, you should pull over safely as soon as possible and check what the cause is. If there is a problem with the bulb, change the bulb or tighten the bulb, and if there is a problem with the fuse, change the fuse.

If a lamp does not turn on, the filament is generally burned out. Remove the bulb and inspect it, and if the bulb is damaged, replace it with a new one. If several lights are not on, honk the horn, and the horn does not sound, it may be that the fuse of the general insurance is blowing.

If the bulb that belongs to the same fuse does not light up, the fuse may be blowing.

When dealing with both types of problems, the cause of the overload should be identified before resetting the fuse or replacing it with a new one. The method is to unplug the wiring of each lamp connected to the fuse from the lamp base, and use the multimeter resistance file to measure the resistance between the lamp end and the lap iron, if the resistance is small or 0, it can be concluded that there is a lap iron fault in the line. After troubleshooting, replace the fuse with a new one.

The precautions when using car lights are:

1. Turn on the low beam when driving at night;

2. When the rear car and the front car driving in the same direction are driving in close proximity, high beams shall not be used;

3. When passing through sharp bends, slopes, arch bridges, pedestrian crossings or intersections without traffic signal control at night, high and low beams should be used alternately.

The lighting system is very important for driving safety, whether it is day or night, you need to use the light prompt, if the light fails, it must be solved as soon as possible, otherwise it will be fined if it is caught by the traffic police.

Hello, it is common to use a diagnostic instrument to eliminate the fault, and then test the car again.

You can use a troubleshooter to eliminate it.

For this case, we need to make a preliminary judgment work:

De-energize the positive or negative pole of the car battery, disconnect it for a few seconds, and then install it. After that, start the car and see if the engine fault light will be lit when the instrument is still on, which means that there is no problem with the engine and there is no need to go to the repair shop to check.

Some high-end cars will lose a lot of data after the power is off, and it needs to be reset again, and the power off needs to be cautious] After doing it, you may encounter three situations: 1The light went out just after I got it down, but it came back a few days later.

2.After the power was cut off, the fault light still did not go out. This situation is that the engine is indeed faulty and needs to be tested by a repair shop.

There are two scenarios when the engine fault light is on:

1. The yellow symbol light indicates that the engine is faulty, but the fault does not affect the normal operation of the engine, but it must be tested and repaired;

2. The red symbol light indicates that the engine has a serious fault, and it needs to be repaired immediately under normal circumstances, if it is in special road conditions, it can be used in an emergency, but it is necessary to pay attention to the working status of the engine at all times.

If the water temperature is too high or the oil pressure warning light is on, if you obviously feel that the vehicle is faulty, you should immediately pull over and call the maintenance station to request rescue to avoid affecting the performance of the engine.

The car fault indicator lights on repeatedly, indicating that the system that the indicator is pointing to may be faulty. It is recommended to go to the car repair shop or 4S shop, use the car fault computer diagnostic instrument to detect the system, read the fault code, you can find the problem, and then according to the fault content prompt, the repair is good, and the broken parts need to be replaced. If it is an occasional failure, use the car fault computer diagnostic instrument, clear the fault code, and the fault indicator will be extinguished!

Hello, dear, during the driving test, I am most afraid of looking at the title of the picture. There are 192 types of car fault lights alone. I'm afraid it will take a lot of work to write them down.

There are many car owners who feel very panicked when facing the car fault lights and don't know how to respond. Next, I will hand you a few little common sense, so that the car owner can easily deal with it!

1.Engine failure lights.

When the engine fault light is on, the reason may be poor quality of fuel, insufficient combustion, excessive accumulation of pollutants inside the engine, etc. In mild cases, the owner can first check the water temperature gauge and oil pressure alarm, if there is no problem, you can continue to drive, but you must go to a special repair shop afterwards to check and troubleshoot. If it is not solved in time, the exhaust gas of the car will increase, increase fuel consumption, wear the engine, and affect the quality of driving.

2.Water temperature alarm indicator.

The water temperature alarm indicator is generally lit, first, the engine water temperature is too high; Second, the coolant is missing. When the engine water temperature is too high, do not rush to turn off the engine, the owner should slow down and stop, and then try to cool down; If you are short of coolant, wait for the temperature of the tank to drop before adding coolant. The owner can also check whether there is any water leakage in the water tank and whether the temperature of the water pipe is normal; Observe whether the fan is operating normally to avoid smooth heat dissipation at high temperatures.

3.ABS anti-lock braking system indicator.

When the ABS fault light is on, the anti-lock system is faulty. The owner does not have to panic and can still continue driving. The ABS anti-lock braking system is used to prevent the wheels from locking, which can reduce the risk of driving to a certain extent.

It can also extend the life of the wheels when the car brakes, improve the braking efficiency, and protect the safety of the owner. Therefore, when it breaks down, the owner must send it to a professional repair shop for repair in time, and don't regret it when the accident happens.

4.Brake system warning light.

Abnormalities in the braking system manifest as poor braking or brake failure. The reason is generally that the brake pads are seriously worn, the ABS is faulty, and the brake fluid does not meet the regulations. If the brake pads are worn, just replace them; Insufficient brake fluid will affect the performance of the brakes and need to be checked immediately at the workshop.

If the accident occurs suddenly, the owner can first check whether the brake fluid level is normal, and observe the brake fluid level sensor and instrument cluster.

The fault indicator light is repeatedly on, indicating that the system pointed to by the indicator light may have a fault, read the fault code, you can find the problem, and then according to the fault content prompt, the repair is good, and the broken accessories need to be replaced.

The main reasons why the fault light is on are:

1. The combustion state is not good.

2. Engine knocking.

3. The fuel quality is not good.

4. The inside of the engine cylinder is not clean and there is deposited carbon.

5. The computer cannot obtain the engine data.

Hello, very happy to answer your question, if the fault light is eliminated, and lit again, the quality, first of all, the fault should be said to be a real fault to enter the fault diagnostic instrument to read the fault code, and then find the corresponding position for a judgment fault maintenance, thank you.

Answer: Hello pro Generally, when the car fault light is on, it cannot be eliminated manually, and it can usually be eliminated after troubleshooting with a fault detector in the 4S store. Generally speaking, there are two situations when the engine fault light is on: 1. The yellow symbol light indicates that the engine is faulty, but the fault does not affect the normal operation of the engine, but it must be tested and repaired; 2. The red symbol light indicates that the engine has a serious fault, and it needs to be repaired immediately under normal circumstances.

If the water temperature is too high or the oil pressure warning light is on, if you obviously feel that the vehicle is faulty, you should immediately pull over and call the maintenance station to request rescue to avoid affecting the performance of the engine. Vehicle fault light is generally caused by the fuel emission system, when the fault light is on, the vehicle is started, extinguished, started, extinguished three times and then started the vehicle, to observe whether the fault light is still lit, or to light it up, you need to go to the store in time to check the fault code, to determine that it is the problem of the engine back to the sensor failure.

The main reasons why the car fault light is on are:

1. The combustion state is not good.

2. Engine knocking.

3. The fuel quality is not good.

4. The inside of the engine cylinder is not clean and there is deposited carbon.

5. The computer cannot obtain the engine data.

If this phenomenon occurs, it is definitely a problem with the engine of the vehicle, and it is recommended to check it carefully.

The faulty light is on because the lighting system is malfunctioning. Faulty lamps can only be eliminated if the lighting system is faulty. There are five common types of light decay lamps, and the specific elimination methods are as follows:

1.Brake system fault light: If the brake system fault light is on, confirm that the handbrake is fully released.

If the handbrake is still there when you release it, check that the brake fluid level is normal or that the brake pads are too thin. At this time, if the braking force is not weakened, you can drive cautiously and go to the nearest repair shop for repair as soon as possible. After all, the quality of braking is directly related to people's driving safety.

2.Oil Pressure Fault Light: The oil pressure fault light is used to display the oil stock and pressure in the engine, and the color is mainly red or yellow.

Turn the key, the indicator light will light up during the vehicle self-test, and the indicator light will automatically turn off when the vehicle is started. If the indicator light stays on, it may be that the oil level or pressure is lower than the standard value. Refill the oil immediately.

If the faulty lamp is still not eliminated after refueling, then it is necessary to stop, turn off the engine, and call the maintenance personnel of the 4S shop. 3.Water Temperature Warning Light:

The danger of lighting the water temperature warning state closed excavation warning light is the same as the danger of lighting the oil pressure failure lamp. The water temperature indicator is used to display the temperature core of the coolant in the vehicle's engine. Sometimes a smoking car in front of the vehicle will stop on the side of the road, indicating that the engine temperature is too high because you don't notice the water temperature.

If the water temperature is too high, the coolant will usually decrease. If coolant is available, add some coolant. If not, add some purified water and continue driving.

However, you must not ignore the situation because the consequences can be severe. Too high temperature will cause the engine to heat up, deform the cylinder block, and affect driving safety. Fault Lights:

ABS fault light is used to display the working status of the vehicle's ABS system, and the color is mainly yellow. Turn the key, the indicator light will light up during the vehicle self-test, and the indicator light will automatically turn off when the vehicle is started. If the indicator light does not light up during the car self-test, or the indicator light stays on after starting the car, it means that the ABS system may be faulty.

5.Engine fault light: The engine fault light is used to show the working status of the engine, and the color is mainly yellow.

Turn the key, the indicator light will light up during the vehicle self-test, and the indicator light will automatically turn off when the vehicle is started. If the indicator light stays on after starting the car, it means that the engine system may be faulty.
