What do car fault lights represent? What are the car fault lights?

How to judge the problem of the vehicle according to the fault light lit on the dashboard. Che Shao taught the children's shoes to recognize these strange signs.

You should be the vehicle after a long time parked, the vehicle's battery is insufficient, the vehicle's battery is insufficient, after the ignition starts, these fault lights are lit up, if it is not a long-distance drive, it can run, or drive to your local brand battery store, to charge the vehicle's battery. When the battery is fully charged, re-ignite.

The meaning of the car fault indicator.

1. Tire pressure warning light:Yellow sign, an irregular circle with no seal on top, four small spikes below, and an exclamation point inside. When this sign appears, it means that the tire pressure of the car tire is abnormal, and the tire should be checked in time.

2. Water temperature indicator: This indicator light is generally always on when the car is just started, especially in winter, the blue thermometer-like shape, the water temperature will be lit if the temperature is too high or too low. Some vehicles will have a thermometer in the dashboard, and the pointer will rise or fall with the temperature of the water.

3. Oil pressure indicator:An icon on the dashboard that resembles a "kettle" is the oil pressure indicator, which lights up when the oil pressure is abnormal. When the vehicle starts, the oil pressure indicator will illuminate.

If the oil pressure is normal, it will then be extinguished. If there is an abnormality in the oil pressure, it will always be lit.

4. Warning light of braking system: () on both sides, a circle in the middle, an exclamation point inside, and the entire icon in red. Indicates that there is a problem with the braking system, such as the level of the brake fluid is too low, the handbrake is pulled up, and so on.

5. Battery indicatorIn the process of car driving, the battery is a main function, if there is a problem with this function, then it will cause problems in car driving.

The red indicators are all fault warning lights, so when you see the car indicator turning red, then pull over quickly.

The red warning lights mainly include: oil pressure warning light, engine temperature warning light, charging warning light and brake fluid level warning light.

Without the sense of urgency of the flashing red indicator, many car owners do not pay attention to the flashing of the yellow indicator. However, the appearance of the yellow indicator light means that there is a safety hazard in your vehicle, such as if a light bulb on the car is broken, the "light bulb warning light" will keep flashing to prompt replacement.

Tachometer. The tachometer is generally set up in the dashboard. Placed symmetrically with the speedodometer. The tachometer works according to the magnetic principle, and it receives the pulse signal generated when the primary current in the ignition coil is interrupted.

And convert this signal into a displayable rotational speed value. The faster the engine speed, the more pulses are generated by the ignition coil.

Now cars are generally electronic tachometer, with pointer and liquid crystal digital display, and there is a digital integrated circuit in the meter, which drives the pointer to move or digital display after calculating the voltage pulse delivered by the ignition coil.

Generally, there are the following reasons: 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.

The specific situation is analyzed as follows; 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. The extender can also cause the engine failure light to come on.

The car fault light indicates that when the vehicle is ready to start, there are some faults in the vehicle, and the car dashboard indicator light will be on or flash red to indicate danger, yellow to indicate failure, and green to indicate normal operation.

This is the engine fault light, it is recommended to go to the 4s or repair plant to read the fault code to locate the fault, only by looking at the fault code can you know what fault pro!

There are too many design contents for this problem, and the fault lights are not the same for different cars. It's best to search for "Car Fault Lights" to find out. Or go to the official websites of major automobiles to find out.

The car fault lights are: 1. Oil pressure indicator light, this light is the oil alarm light, if the lamp is always on, it means that the stock and pressure of the engine oil are lower than the standard value; 2. When the lamp is on, first check whether the handbrake is completely released, if the light is still on after releasing the handbrake, you need to check whether the brake fluid level is normal, or whether the brake pads are too thin; 3. Steering power warning light, this light is on to indicate that there is a problem with the power steering system; 4. Spike roll engine self-test indicator, this light is used to remind the driver whether the engine is running normally, if it is normal, it will automatically go out, if this light has been on, it means that the engine is faulty; 5. Tire pressure warning light, this light is used to show the condition of tire pressure, if it is normal, this light is off, otherwise it may be insufficient tire pressure or tire damage.

1. Battery indicator.

The battery indicator is used to show the working status of the car battery, and its color is usually red or yellow. Twist the key, the indicator light will light up when the vehicle performs self-inspection, and the indicator light will automatically turn off when the car is started.

2. Engine indicator.

The engine indicator is used to show the working status of the engine, and its color is mainly yellow. Twist the key, the indicator light will also light up when the vehicle performs self-inspection, and the indicator light will automatically turn off when the car is started.

3. ABS indicator light.

ABS indicator light is used to show the working status of the vehicle's ABS system, and its color is mainly yellow. Twist the key, the indicator light will light up when the vehicle performs self-inspection, and the indicator light will automatically turn off when the car is started.

4. Oil lamp.

The oil alarm light is usually caused by low oil pressure or damage to the oil pump. The pressure sensor monitors the oil pressure status of the car at all times. Too low oil pressure can cause problems with lubrication or even dry friction, leading to engine damage.

The oil alarm light is on, and it must be repaired in time.

5. Water temperature alarm indicator.

When this light is on, first pull over and turn off the engine immediately, check whether there is a lack of coolant, or the water temperature is too high, and then replenish the coolant or continue driving when it cools to the normal operating temperature of the engine.

Common car fault lights include oil warning lights, water temperature indicators, engine fault lights, brake system fault lights, ABS fault lights, low oil pressure warning lights, seat belt indicators, etc.

1.Oil warning light. Only normal oil pressure ensures that the oil is delivered to the surface of all friction parts of the engine. Too high or too low will affect the normal operation of the engine, and even cause damage to engine parts.

2.Water temperature indicator. The water temperature indicator mainly indicates the temperature of the coolant in the water tank when the engine is working. Some models that do not have a water temperature gauge will display the coolant temperature in the color of the indicator: blue indicates that the water temperature is too low; Indicates that the water temperature is normal; Red indicates that the water temperature is too high.

3.Engine failure lights. The engine fault light is used to show the working status of the engine, and the color is mainly yellow.

When the key is turned, the indicator light will also 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.

4.Brake system fault light. If the brake system fault light is on, make sure the handbrake is fully released.

If the handbrake is still on when released, 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 should drive carefully and repair it as soon as possible. After all, the quality of the brakes is directly related to driving safety.

Faulty lights. ABS is also called anti-lock braking system. The indicator light is mainly yellow.

In an emergency, the brake pedal must be fully depressed to activate the anti-lock braking system. If the indicator light does not light up during the car self-test, or the ABS indicator light keeps on after the car starts, it means that the anti-lock braking system may be faulty, which will greatly reduce the safety of the car.

Common car fault lights, organic oil warning lights, water temperature indicators, engine fault lights, brake system fault lights, ABS fault lights, low oil pressure warning lights, seat belt indicators and so on.

1. Oil alarm light. Only normal oil pressure can ensure that the oil is delivered to all the friction parts of the engine, too high or too low will affect the normal operation of the engine, and even cause damage to engine parts.

2. Water temperature indicator. The water temperature indicator mainly indicates the temperature of the coolant in the water tank when the engine is working. Some models that do not have a water temperature gauge will show the coolant temperature in the color of the indicator

Blue means that the water temperature is too low; Off means that the water temperature is normal; Red indicates that the water temperature is too high.

3. Engine fault lamp. The engine fault light is used to show the working status of the engine, and its color is mainly yellow. Twist the key, the indicator light will also light up when the vehicle is self-checked, and the indicator light will turn off after starting the car.

If the light is always on after starting the car, it means that the engine system may be faulty.

4. Brake system fault lamp. If the brake system fault light is on, first make sure that the handbrake is fully released. If the handbrake is still bright 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 need to drive cautiously and go to repair as soon as possible, after all, the quality of the brakes is directly related to driving safety.

5. ABS fault lamp. ABS is also known as anti-lock braking system. The color of the indicator is mainly yellow.

In case of emergency, the brake pedal must be pressed all the way to activate the ABS system. If the indicator light does not light up during the car self-test, or the ABS indicator light is always on after starting the car, it means that the anti-lock braking system may be faulty, which will greatly reduce the safety of the vehicle.
