Will the fault light on the dashboard of the car come on?

For example, engine fault lights, tire pressure warning lights, oil warning lights, and so on. Depending on the model, the difference will be large. It is recommended to check the vehicle instruction manual, which will have a clear explanation.

Solution: Stop for inspection, if the situation is more serious, don't continue driving, contact a 4S shop or a professional auto repair shop as soon as possible, and ask for professional help.

Glad to be able to your question, Xu my help to you, will the fault light of the car dashboard light illuminate? First of all, we are lighting the fire, not for the fight, but the fire is a difference, if it is our car hit, and then the fire kicks and then the fault lights should all be extinguished.

Of course I would, do you want that?

The fault indicator light is on, there may be a problem! You need a car computer detector, detect it, you can find out what the fault is, and then eliminate it according to the fault information, there is no other way!

The reason why the car dashboard light is fully lit:

The CAN bus of the ECU is faulty, and the CAN interface of the ECU is not in good contact.

Excessive dirt and carbon deposits, abnormal air circulation, and inability to accurately control the normal air intake volume, resulting in unstable gas content, so that the engine cannot work well.

The low fuel pressure combined with the poor constant pressure performance leads to a low level of atomization in the system, making it difficult for the car to start.

There is a lack of power in the system. Pay attention to check the battery level.

It is recommended to go to the car repair shop for maintenance and testing to ensure the safety of travel, thank you!

The car dashboard headlight sign is always on, it may be that you accidentally did not pull the light button back to its original position, or it may be that you are driving for a time in road conditions with insufficient light, such as night, rainy days, etc., the lights will be automatically turned on. Your greatest probability is the previous one. You put the light button back in place.

This is because your headlights are not turned off, if your headlight switch is turned on by turning the lever under the left-hand position of the steering wheel in two gears, then this indicator light means that the headlight switch is on one gear, not fully on, and not completely closed.

This is the vehicle's low beam, which is usually automatically activated and will be automatically turned on in a dark place or on a rainy day. When driving at night, it is only used as a street light, and the high beam should be turned on manually if the road lighting is not good.

This is the high beam switch is not turned off, and there is no such logo when it is turned off.

It may be that the small light is not turned off, or there is a problem with the meter, check it yourself.

It seems to be a fog lamp, and the rod on the left is turned off with a twist of the tail end.

Isn't this a daytime running light with a wide indicator light.

There are several reasons for this:

1. The combustion state is not good.

The poor combustion state of the engine is the main reason why the yellow light on the dashboard is on.

2. Engine knocking.

There are generally three scenarios:

The first case: the car is weak;

The second case: the car is weak and the engine noise is too loud;

The third case: there is an obvious knocking sound.

In the first case, the engine fault light may be on (depending on the quality of the manufacturer's parts), and in the second and third cases, the yellow light will definitely be on.

3. The internal reason why the engine failure light is on.

1) The fuel quality is not good.

2) The inside of the engine cylinder is not clean.

4.When the cold car is started, especially when the weather temperature drops sharply, the fault light will be on when starting due to the temperature correction problem of the computer, and it will not light up as long as the temperature rises to a certain temperature and stabilizes.

5.The age of the car is too old, and the aging of the device leads to abnormal operation of the engine, which causes the combustion ignition to be poor, resulting in the fault light being on.

6.Some of the sensors themselves are faulty, causing the fault light to turn on.

The reason why the car fault light is on is the failure of the water temperature sensor, the failure of the crankshaft sensor, the failure of the oxygen sensor, the failure of the spark plug, the failure of the ignition coil, etc. After the engine fault light is on, it can be divided into three situations: 1. The car cannot be started, which may be a failure of the fuel pump or ignition parts, and you can directly call ** for help; 2. The fault light is on, but there is no abnormality in driving, this may just be a sensor failure, you can continue to drive temporarily, but you should slow down at low and medium speeds; 3. The engine fault light is on, and the vehicle can be driven, but there are symptoms such as severe shaking and acceleration weakness, and in the face of this situation, you can only stop and call for rescue.

There are many faulty lights on the dashboard of a car, and there are many different shapes of specific lights. The most common ones are engine fault lights, liquid level alarm fault lights, keyless fault lights, and vehicle fault lights.

After the engine fault light is on, it needs to be interpreted and cleared with a decoding instrument.

If the fault light is red, you need to immediately turn off the engine and wait for rescue, if it is yellow or other colors, you can continue to drive.

There are many kinds of faulty lights on the car dashboard, and you can go to the auto repair shop or the fourth shop to check and repair it.

You can go to the repair shop and check it out.

It's best to send a ** up to see what kind of fault is causing it.

Instrument panels, rigid slabs or structural parts for the installation of instruments and related devices. According to the type, there are screen instrument panels, frame instrument panels, channel instrument panels, and cabinet instrument panels.

Summary. After starting, there are many fault lights on the instrument, which means that the vehicle's control system is faulty. It may be that the circuit of the body control module is expected to be loose, and it may be that the circuit board of the engine control computer is connected, or the circuit board of the engine control computer itself is problematic.

You can turn off the engine and restart it, if it still doesn't work, you can disconnect the negative terminal of the battery for a minute and then reconnect it. Take a look at whether these fault lamps can disappear, if it still doesn't work, you need to use the computer to detect, and deal with the maintenance according to the fault of the computer detection.

It may be that the action of the sensor and the dynamic turning light servo motor is contradictory due to the problem of light angle, and the fault of the position sensor of the right rotation module that occurs afterwards makes the fault light flash, and the owner can turn on the light for a simple road test after clearing the fault code.

More often than not, the failure of the car lamp will not be limited to small problems such as burned out bulbs, corroded sockets or damaged plugs, and professional diagnostic techniques are often required to analyze the root cause of the failure. Even for those low-priced cars, the interior and exterior lights are controlled by the main computer.

Precautions for lights.

The function of high and low beams is to illuminate at night, and high beams can improve the line of sight and expand the field of view.

On a pitch-black road with no street lights, the visibility range with the high beams on is much greater than when the low beams are on. The low beam is used for close lighting, the irradiation distance is short, and the concentrator cannot be adjusted, and the irradiation distance is about 30-40 meters.

The car macro hidden light is on because the voltage and current are still stable output, and the fault light is on means that the sensor is either unable to read the light data, or the current and voltage changes are not up to standard. It is recommended to check it, especially for the question of current overload.

Hello, generally it is a bulb problem, there is a bulb of poor quality that needs to be replaced.

It may be that there is a problem with the car line, it is recommended not to continue driving, go to the repair shop to check the problem.

In this case, first go to the car Weiqing jujube repair factory to detect whether it is a fault code and need to be eliminated with a sail and plum fault diagnostic instrument. Then it will be tested. Front and rear headlights as well as interior lights.

Is it not the same model of the replacement bulb.

The water temperature is high, or there is a problem with the machine.

You need to go to the repair station to check and decode.

The fault light of the car dashboard may be a fault of the parking sensor, the wear of the brake pads exceeds the potato beam standard, the engine oil pressure sensor is faulty, the brake fluid is insufficient, and the oil cut-off system intervenes or malfunctions.
